Resumen

Deep-sea environments face increasing pressure from anthropogenic exploitation and climate change, but remain poorly studied. Hence, there is an urgent need to compile quantitative baseline data on faunal assemblages, and improve our understanding of the processes that drive faunal assemblage composition in deep-sea environments. The Southwest Atlantic deep sea is an undersampled region that hosts unique and globally important faunal assemblages. To date, our knowledge of these assemblages has been predominantly based on ex situ analysis of scientific trawl and fisheries bycatch specimens, limiting our ability to characterise faunal assemblages. Incidental sampling and fisheries bycatch data indicate that the Falkland Islands deep sea hosts a diversity of fauna, including vulnerable marine ecosystem (VME) indicator taxa. To increase our knowledge of Southwest Atlantic deep-sea epibenthic megafauna assemblages, benthic imagery, comprising 696 images collected along the upper slope (1070–1880 m) of the Falkland Islands conservation zones (FCZs) in 2014, was annotated, with epibenthic megafauna and substrata recorded. A suite of terrain derivatives were also calculated from GEBCO bathymetry and oceanographic variables extracted from global models. The environmental conditions coincident with annotated image locations were calculated, and multivariate analysis was undertaken using 288 ‘sample’ images to characterize faunal assemblages and discern their environmental drivers. Three main faunal assemblages representing two different sea pen and cup coral assemblages, and an assemblage characterised by sponges and Stylasteridae, were identified. Subvariants driven by varying dominance of sponges, Stylasteridae, and the stony coral, Bathelia candida, were also observed. The fauna observed are consistent with that recorded for the wider southern Patagonian Slope. Several faunal assemblages had attributes of VMEs. Faunal assemblages appear to be influenced by the interaction between topography and the Falkland Current, which, in turn, likely influences substrata and food availability. Our quantitative analyses provide a baseline for the southern Patagonian shelf/slope environment of the FCZs, against which to compare other assemblages and assess environmental drivers and anthropogenic impacts.

Resumen

Among the equid species named from the Cypress Hills Formation (Eocene to Miocene) of Saskatchewan, Mesohippus westoni and M. propinquus are documented from the early Chadronian Calf Creek local fauna, and M. westoni is also known from the earlier Southfork local fauna and from other Chadronian and Orellan deposits of western North America. Teeth possibly referable to Miohippus assiniboiensis are found in association with Whitneyan or early Arikareean assemblages. Miohippus grandis, not M. assiniboiensis, is the correct reference for larger Chadronian equids from Calf Creek and other local faunas. Archaeohippus stenolophus (new combination) is preserved in latest Arikareean or early Hemingfordian beds of the Cypress Hills, and occurs in faunal assemblages that show strong resemblances to the Runningwater assemblage of Nebraska.

Resumen

The Greek fossil record of small and large mammal Local Faunal Assemblages is studied and compared by means of cluster analysis techniques using Jaccard similarity index and unweighted pair-group method. The analysis allow recognizing a good arrangement of the Greek LFAs according to time and a main cluster gap, corresponding to an important faunal renewal that, however, is not synchronous in the large and small mammal community. Minor groupings of large mammal faunas seem also to fit with main climatic trends, whereas the small mammal assemblage appears to undergo longer periods oftaxonomic stability

Resumen

A faunal assemblage may be dominated by dense bones either because the soft ones have been transported away or because they have been gnawed beyond recognition. Archaeologists have often despaired of distinguishing between these hypotheses and have attributed the problem to equifinality-to the fact that different causes can produce identical outcomes. Yet under the models of transport and attrition studied here, these causes do not produce identical outcomes. It has been difficult to distinguish between them only because conventional statistical methods lack power. Using the new method of abcml (Analysis of Bone Counts by Maximum Likelihood), it is easy to distinguish assemblages that were deposited by different agents. It is also possible to distinguish between assemblages that have suffered differing degrees of attritional damage, but this distinction is more difficult to make. It is also shown that the conventional method for recognizing attritional damage in faunal assemblages is remarkably low in power. The paper closes with a discussion of the word "equifinality" itself.

Resumen

Context. World-wide, primary forest is in decline. This places increasing importance on understanding the use by biodiversity of regrowth (secondary) forest, and on the management of such regrowth. Aims. This study aimed to compare the terrestrial vertebrate assemblages in tropical eucalypt forests, regrowth in these forests (following clearing for pastoral intensification) and cleared land without regrowth, to provide evidence for developing management guidelines for regrowth vegetation in a region (the Daly catchment of the Northern Territory) subject to increasing demands for land-use intensification. Methods. The terrestrial vertebrate fauna was surveyed consistently at 43 quadrats sampling forest, 38 sampling regrowth and 19 sampling cleared land (formerly forest), and the faunal composition was compared with ordination and analysis of variance. Further analysis used generalised linear modelling to include consideration of the relative importance of disturbance (condition) of quadrats. Key results. Faunal assemblages in regrowth vegetation were found to be intermediate between cleared land and intact forest, and converged towards the faunal assemblage typical of intact forest with increase in the canopy height of the regrowth. However, even the tallest regrowth quadrats that were sampled supported relatively few hollow-associated species. The management of fire, weeds and grazing pressure substantially affected the faunal assemblages of the set of regrowth and intact forest quadrats, in many cases being a more important determinant of faunal attributes than was whether or not the quadrat had been cleared. Conclusions. In this region, regrowth vegetation has value as habitat for fauna, with this value increasing as the regrowth structure increases. The convergence of the faunal composition of regrowth vegetation to that of intact forest may be substantially affected by post-clearing management factors (including fire regime and level of grazing pressure and weed infestation). Implications. Regrowth vegetation should be afforded appropriate regulatory protection, with the level of protection increasing as the regrowth increases in stature.

Resumen

AbstractAccurately recognizing analogues between fossil and modern ecosystems allows paleoecologists to more fully interpret fossil assemblages and modern ecologists to leverage the fossil record to address long-term ecological and environmental changes. However, this becomes increasingly difficult as taxonomic turnover increases the dissimilarity between ecosystems. Here we use a guild-based approach to compare the ecological similarity of Cretaceous cold-seep assemblages preserved in the Pierre Shale surrounding the Black Hills and modern cold-seep assemblages from five previously recognized biofacies. We modify modern assemblage data to include only those taxa with fossilizable hard parts greater than 5 mm in length to make these modern data sets more comparable to potential fossil analogues. We find that while the Black Hills assemblages are more similar in ecological guild composition to the modern thyasirid biofacies, subsets share similarities in ecological structure to the lucinid and mussel-bed biofacies. The fossil seep assemblages are also more similar to one another than are modern assemblages belonging to the same biofacies, despite greater geographic and temporal dissimilarity among the fossil samples. Furthermore, guild-level ordination analyses show a secondary faunal gradient that reflects community succession in the hard substrate–dominated modern assemblages and reveals a parallel faunal gradient in the soft sediment–dominated Cretaceous assemblages, consistent with a gradient in the influence of seep fluids on the faunas. Thus, while the Black Hills assemblages are quite homogeneous in their composition, they capture ecological variation similar to successional patterns in modern seep systems.

Resumen

The Early Pleistocene was a critical time period in the evolution of eastern African mammal faunas, but fossil assemblages sampling this interval are poorly known from Ethiopia’s Afar Depression. Field work by the Hadar Research Project in the Busidima Formation exposures (~2.7–0.8 Ma) of Hadar in the lower Awash Valley, resulted in the recovery of an early Homo maxilla (A.L. 666-1) with associated stone tools and fauna from the Maka’amitalu basin in the 1990s. These assemblages are dated to ~2.35 Ma by the Bouroukie Tuff 3 (BKT-3). Continued work by the Hadar Research Project over the last two decades has greatly expanded the faunal collection. Here, we provide a comprehensive account of the Maka’amitalu large mammals (Artiodactyla, Carnivora, Perissodactyla, Primates, and Proboscidea) and discuss their paleoecological and biochronological significance. The size of the Maka’amitalu assemblage is small compared to those from the Hadar Formation (3.45–2.95 Ma) and Ledi-Geraru (2.8–2.6 Ma) but includes at least 20 taxa. Bovids, suids, and Theropithecus are common in terms of both species richness and abundance, whereas carnivorans, equids, and megaherbivores are rare. While the taxonomic composition of the Maka’amitalu fauna indicates significant species turnover from the Hadar Formation and Ledi-Geraru deposits, turnover seems to have occurred at a constant rate through time as taxonomic dissimilarity between adjacent fossil assemblages is strongly predicted by their age difference. A similar pattern characterizes functional ecological turnover, with only subtle changes in dietary proportions, body size proportions, and bovid abundances across the composite lower Awash sequence. Biochronological comparisons with other sites in eastern Africa suggest that the taxa recovered from the Maka’amitalu are broadly consistent with the reported age of the BKT-3 tuff. Considering the age of BKT-3 and biochronology, a range of 2.4–1.9 Ma is most likely for the faunal assemblage.

Resumen

Title (Bahasa Indonesia): Kumpulan fauna bentik di hamparan lamun di Albany, Australia Barat In order to compare benthic fauna assemblages in four locations of seagrass beds in Albany (Princess Royal Harbour, Oyster Harbour, Two People Bay and Frenchman Bay), a research had beenconducted between 18 and 21 April 2017. There were two aims of this study. First, to investigate six sites within four locations with various degree of anthropogenic impact in order to understand the faunal richness and abundance in those locations. Second, to measure and record the environmental factors which are assumed to be important regulators of the observed patterns between the sites. The result showed that the highest faunal abundance (227 Faunal) was found at Frenchman Bay, a less anthropogenically impacted area, while the lowest abundance (26 Faunal) was at Oyster Harbour-Emu Point which was an anthropogenically affected site. However, in terms of faunal diversity, there was no significant difference among all sites. The environmental factor which had significant relationship with the difference in benthic faunal assemblages at each site was found to be coarse sand.Satu kegiatan penelitian pada tanggal 18 hingga 21 April 2017 telah dilakukan untuk membandingkan kumpulan fauna bentik di empat lokasi padang lamun di Albany (Pelabuhan Princess Royal, Pelabuhan Oyster, Teluk Two People, dan Teluk Frenchman). Penelitian inimempunyai dua tujuan, yaitu: 1) menyelidiki enam titik penelitian yang beradadalam empat lokasi dengan berbagai tingkat dampak antropogenik untuk memahami kekayaan dan kelimpahan fauna di lokasi tersebut; dan 2) mengukur dan mencatat faktor-faktor lingkungan yang dianggap berperan sebagai pengaturdari pola yang diamati pada semua lokasi. Hasil penelitian menunjukkan,bahwa kelimpahan fauna tertinggi (227 fauna) ditemukan di Teluk Frenchmanyang merupakandaerah yang kurang terdampak gangguan antropogenik;sedangkan kelimpahan terendah (26 individu) ditemukandi Oyster Harbour-Emu Point yang merupakan lokasi yang terpengaruh secaraantropogenik. Namun, dalam hal keanekaragaman fauna, tidak ada perbedaan yang signifikan di antarasemua lokasi. Faktor lingkungan yang memiliki hubungan signifikan dengan perbedaan kumpulan fauna bentik di masing-masing lokasi ialah pasir kasar.

Resumen

We provide the first detailed systematic taxonomy and paleoecological investigation of late Paleozoic brachiopod faunas from Korea. Specifically, we focus on the brachiopods from the Geumcheon-Jangseong Formation, the lower part of the Pyeongan Supergroup in the Taebaeksan Basin. The formation yields a variety of marine invertebrate fossils, including brachiopods, molluscs, echinoderms, corals, fusulinids, and conodonts. Diverse brachiopods are described from six siliciclastic horizons of the formation at three localities, including 23 species belonging to 20 genera with two new species: Rhipidomella parva n. sp. and Stenoscisma wooi n. sp. Three brachiopod assemblages of the late Moscovian (Pennsylvanian) age are recognized based on their species compositions and stratigraphic distributions, namely the Choristites, Rhipidomella, and Hustedia assemblages. The brachiopod faunal composition varies within each assemblage as well as between the Assemblages, most likely reflecting local paleoenvironmental and hence paleoecological differences. The Choristites Assemblage includes relatively large brachiopods represented by Derbyia, Choristites, and Stenoscisma and may have inhabited open marine to partly restricted marine environments, whereas the Rhipidomella and Hustedia Assemblages consist of a small number of small-sized brachiopods living in lagoonal environments. The Choristites Assemblage shows a close affinity with Moscovian brachiopod assemblages in the eastern Paleo-Tethys regions, especially the Brachythyrina lata-Choristites yanghukouensis-Echinoconchus elegans Assemblage of North China, whereas the Rhipidomella and Hustedia assemblages both exhibit strong endemism.

Resumen

Arcellinida (testate lobose amoebae) were examined from 40 near-surface sediment samples (top 0.5 cm) from two lakes impacted by arsenic (As) contamination associated with legacy gold mining in subarctic Canada. The objectives of the study are two folds: quantify the response of Arcellinida to intra-lake variability of As and other physicochemical controls, and evaluate whether the impact of As contamination derived from two former gold mines, Giant Mine (1938–2004) and Tundra Mine (1964–1968 and 1983–1986), on the Arcellinida distribution in both lakes is comparable or different. Cluster analysis and nonmetric multidimensional scaling (NMDS) were used to identify Arcellinida assemblages in both lakes, and redundancy analysis (RDA) was used to quantify the relationship between the assemblages, As, and other geochemical and sedimentological parameters. Cluster analysis and NMDS revealed four distinct arcellinidan assemblages in Frame Lake (assemblages 1–4) and two in Hambone Lake (assemblages 5 and 6): (1) Extreme As Contamination (EAC) Assemblage; (2) High calcium (HC) Assemblage; (3) Moderate As Contamination (MAC) assemblages; (4) High Nutrients (HN) Assemblage; (5) High Diversity (HD) Assemblage; and (6) Centropyxis aculeata (CA) Assemblage. RDA analysis showed that the faunal structure of the Frame Lake assemblages was controlled by five variables that explained 43.2% of the total faunal variance, with As (15.8%), Olsen phosphorous (Olsen-P; 10.5%), and Ca (9.5%) being the most statistically significant (p < 0.004). Stress-tolerant arcellinidan taxa were associated with elevated As concentrations (e.g., EAC and MAC; As concentrations range = 145.1–1336.6 mg kg−1; n = 11 samples), while stress-sensitive taxa thrived in relatively healthier assemblages found in substrates with lower As concentrations and higher concentrations of nutrients, such as Olsen-P and Ca (e.g., HC and HM; As concentrations range = 151.1–492.3 mg kg−1; n = 14 samples). In contrast, the impact of As on the arcellinidan distribution was not statistically significant in Hambone Lake (7.6%; p-value = 0.152), where the proportion of silt (24.4%; p-value = 0.005) and loss-on-ignition-determined minerogenic content (18.5%; p-value = 0.021) explained a higher proportion of the total faunal variance (58.4%). However, a notable decrease in arcellinidan species richness and abundance and increase in the proportions of stress-tolerant fauna near Hambone Lake’s outlet (e.g., CA samples) is consistent with a spatial gradient of higher sedimentary As concentration near the outlet, and suggests a lasting, albeit weak, As influence on Arcellinida distribution in the lake. We interpret differences in the influence of sedimentary As concentration on Arcellinida to differences in the predominant As mineralogy in each lake, which is in turn influenced by differences in ore-processing at the former Giant (roasting) and Tundra mines (free-milling).

Resumen

Previous research has shown that a range of physical and biological drivers can influence the composition of faunal assemblages occupying localities within streams. There is much debate in the literature about which of these is more important. Descriptive and experimental field studies were conducted in two relatively undisturbed, second order rainforest streams in southeast Queensland, Australia. The principal objectives were to describe spatial and temporal patterns in pool fauna and explore relationships between these patterns and physical attributes of habitat, disturbance and biotic interactions. The macroinvertebrate and vertebrate fauna of 12 small stream pools were sampled approximately monthly over a period of 15 months. Samples were collected from all major within-pool habitat types and concurrent measurements of potentially important environmental parameters were made at landscape scales of stream, pool and habitat patch. Faunal assemblages were consistently different between the two streams and between the various within-pool habitat types, although the latter may partially be explained by differences in sampling protocols applied in the different habitat types. However, spatial and temporal variation in faunal assemblages within habitat types was large at the scales of whole pools and within-pool habitats, and this variation occurred apparently independently of variation in physical habitat attributes. These results indicated that very little of the local scale faunal variation could be explained by abiotic drivers and that some other factors must be responsible for the observed faunal patterns. Previous research had indicated that atyid shrimps can play a significant ecological role in rainforest streams, where they act as 'ecosystem engineers' by removing fine sediment from hard surfaces. This subsequently alters algal dynamics and faunal composition in streams. A pool-scale manipulative experiment was conducted to investigate the role of the atyid Paratya australiensis, which is an abundant and conspicuous component of the fauna. Removal of shrimp from pools had no effect on sediment accrual on hard surfaces and consequently did not affect algal biomass or faunal assemblages. The lack of effect on sediment accumulation was attributed to the low rate of deposition in these streams, which was an order of magnitude lower than in streams where atyids have been demonstrated to play a keystone role. The fish Mogurnda adspersa was found to be the primary predator of pool fauna in the study streams, where it preyed on a wide variety of taxa. Dietary analyses revealed that an ontogenetic shift occurred in both diet and the within-pool habitat where fish fed. Within this general framework, individual fish had strong individual prey preferences. Significant correlations were found between the natural abundance of Mogurnda in pools and faunal assemblage patterns in both gravel habitat and pools in general, indicating that predation had an effect on pool fauna. The nature of this effect varied between habitats. A direct density dependent response was observed in gravel habitat. In contrast, the response in pools varied considerably between individual pools, perhaps reflecting the differing prey preferences of individual fish. Despite these correlations, an experimental manipulation of the density of Mogurnda at a whole-pool scale did not conclusively identify a predation effect. This may have been due to problems with fish moving between treatments, despite attempts to constrain them, and low experimental power due to the inherent high variability of pool fauna. Overall, the results of the study indicated that there was considerable spatial and temporal variation in pool fauna despite similarities in the physical attributes of pools and their close proximity. This variation appeared to occur at random and could not be explained by abiotic or biotic factors. Predation had a small effect, but could not explain the overall patterns, whereas disturbance by spates had very little effect at all. Stochastic processes associated with low level random recruitment were identified as a possible and plausible explanation for observed patterns. These conclusions are discussed in terms of their implications for our understanding of the ecology and management of streams.

Resumen

The broad aim of this thesis is to further understanding of British Iron Age animal husbandry regimes by undertaking a comparative study of faunal assemblages. More specifically, this involves development of a uniform methodology for comparing published faunal data in order to recognise inter and intra-regional patterns of animal husbandry. Lack of uniformity in methods of recording and presenting faunal data, together with variation in the quality and quantity of information published in reports, serves as a barrier to systematic quantitative comparison. This thesis therefore seeks to develop methods of comparison which utilise the most commonly available forms of faunal data, or convert different forms of data into a single comparable format, in order that inter and intra-regional analyses of the widest possible dataset can be undertaken. To ensure viable comparisons unaffected by small sample bias, only those sites with total cattle, sheep and pig assemblages of NISP>300 or MNI>30 are included in this study. Analyses concentrate on the three main domestic species (cattle, sheep, and pig) which comprise the bulk of all faunal remains recovered from excavations of British Iron Age sites, and utilise three main types of information: Firstly, representation of different skeletal elements is examined in order to recognise the effects of taphonomic and human alteration on each assemblage. Secondly, quantification data for cattle, sheep, and pig is compared, using tripolar graphs to establish the relative importance of different species in each assemblage. Thirdly, mandibular tooth wear data is used for the composition of mortality profiles to compare herd management strategies. Both species proportions and mortality profiles from different faunal assemblages are compared, and examined for any inter and intra-regional similarities. Subsequently assemblages are examined for relationships between patterns of species proportions and/or mortality profiles and particular site characteristics (topographical location, underlying geology, settlement type, and date). Finally, using the results of these analyses, suggestions are made as to the nature of animal husbandry regimes in different regions, and the factors influencing choice of husbandry strategy in Iron Age Britain.

Resumen

The work for this thesis was undertaken in Broke Inlet, a seasonally-open estuary on the south coast of Western Australia and the only estuary in that region which is regarded as “near-pristine” (Commonwealth of Australia, 2002). The only previous seasonal studies of the environmental and biotic characteristics of this estuary involved broad-based descriptions of the trends in salinity, temperature and ichthyofaunal characteristics at a limited number of sites. Furthermore, no attempt has been made to identify statistically the range of habitats present in the nearshore and offshore waters of this system, and the extents to which the characteristics of the fish and benthic invertebrate faunas are related to habitat type. These types of data provide not only reliable inventories of the habitat and faunal characteristics of Broke Inlet, but also a potential basis for predicting the likely impact of anthropogenic and climatic changes in Broke Inlet in the future. The main aims of this thesis were as follows. (1) To use the method of Valesini et al. (2010), which employs enduring environmental characteristics, to identify quantitatively the range of habitats present throughout the nearshore and offshore waters of Broke Inlet. The enduring environmental characteristics represent three broad categories, i.e. the location of any site in terms of its proximity to marine and freshwater sources, the degree of exposure to wave activity and the type of substrate and/or submerged vegetation. (2) To test the hypothesis that the species richness, density, diversity and species compositions of the fish and benthic macroinvertebrate faunas differ among habitat types, seasons and, in the case of the fish fauna, also years. (3) To test the hypothesis that the pattern of relative differences among habitat types, as exhibited by their faunal compositions, is correlated with that defined by their (i) enduring environmental characteristics and (ii) non-enduring environmental characteristics (water physico-chemical variables and sediment characteristics). A high resolution satellite image and a digital elevation model of Broke Inlet were used to measure the enduring environmental characteristics at 104 and 36 widely-distributed sites in nearshore and offshore waters, respectively. These data were used to construct separate Manhattan distance matrices for nearshore and offshore waters, which were then subjected to the CLUSTER and SIMPROF routines in PRIMER v6 to identify the various groups of sites that did not differ significantly in their environmental characteristics and which were thus considered to represent habitat types. Twelve and four distinct habitat types were identified in nearshore and offshore waters, respectively. The ichthyofaunas at sites representing 11 nearshore (A-K) and three offshore (A-C) habitat types were sampled seasonally for two consecutive years using seine and gill nets, respectively. A total of 83,047 fish was collected from nearshore waters, representing 27 species from 19 families, with 99.6% of those fish belonging to six species which represent the Atherinidae (Atherinosoma elongata, Leptatherina wallacei and Leptatherina presbyteroides) or Gobiidae (Afurcagobius suppositus, Pseudogobius olorum and Favonigobius lateralis) and complete their life cycles within the estuary. Each of these species were found at each nearshore habitat type, except for P. olorum, which was not caught at habitat A. The species richness, density and diversity of the nearshore fish fauna differed significantly among habitats, seasons and years, with habitat being the most influential factor. Generally, mean species richness and density were greatest at habitat types located in the entrance channel (B, G and H) and/or on the southern shore of the basin (C and G), while the fish assemblages were most depauperate at habitats near freshwater sources (A and J). The nearshore ichthyofaunal composition of Broke Inlet differed significantly among habitats, seasons and years, with the first again being the most influential. However, the extents of the overall differences in composition during each sampling occasion were moderate. The lack of very pronounced ichthyofaunal differences among the various habitat types reflects the widespread distributions and high abundances of the above atherinid and gobiid species, and particularly of A. elongata and L. wallacei, which typified the fish fauna of each habitat type on almost all sampling occasions. The most distinctive of the faunas were those at habitat types in the entrance channel, where L. presbyteroides and F. lateralis, which are typically found in higher salinities, were in their greatest densities, and where several marine straggler species, such as the labrids Notolabrus parilus and Achoerodus gouldii, were occasionally caught. Seasonal and inter-annual changes in ichthyofaunal composition were small and often not consistent across habitats. The pattern of relative differences among nearshore habitats in terms of their ichthyofaunal composition was correlated at a moderate level with that defined by their enduring environmental characteristics in all but one of the eight seasons. Such indicate that the ichthyofaunal composition likely to be found at any site in the nearshore waters of Broke Inlet at any time of year can be predicted, simply by assigning that site to its most appropriate habitat type on the basis of its enduring environmental characteristics. Differences in ichthyofaunal composition among habitat types were also correlated, but to a slightly greater extent, with those among the suite of non-enduring water physico-chemical variables, with salinity and the biomass of macrophytes being particularly relevant. Gill netting in the three offshore habitats yielded 1,050 fish representing 31 species. Species richness, catch rates and diversity all varied significantly among habitats, with the values for each of these biotic characteristics always being greatest at habitat A in the entrance channel and lowest at habitat B near the Shannon River mouth. These biotic variables did not always vary, however, among seasons and/or years. In contrast to the situation in nearshore waters, the offshore ichthyofauna comprised mainly marine estuarine-opportunists and marine stragglers, which contributed 84% to the number of species and 80% to the total number of fishes. The contribution of individuals belonging to the marine straggler guild was only 5% and no estuarine resident species were caught. Ichthyofaunal composition in offshore waters differed significantly among habitats, seasons and years, with habitat being the most influential factor. Faunal composition only differed among habitats in spring and autumn, and even then the extent of those differences was low. During those seasons, habitat B contained the most distinct and depauperate fauna, which was typified mainly by Mugil cephalus and Aldrichetta forsteri. In contrast, the fish assemblages at habitats A and C were also typified by Arripis georgianus, Arripis truttaceus, Rhabdosargus sarba, Pagrus auratus, Pseudocaranx dentex and Engraulis australis. The pattern of relative differences among offshore sites in terms of their ichthyofaunal composition was significantly correlated with that defined by their enduring environmental characteristics only in autumn, but was moderately correlated with that exhibited by the suite of non-enduring water physico-chemical variables in each season except summer. Seasonal sampling of benthic macroinvertebrates at six of the nearshore habitat types (A, C, D, F, H and K) for a year yielded 7,485 individuals representing 28 species and seven phyla and, at the three offshore habitat types (A-C), 2,459 individuals representing 26 species and eight phyla. Polychaetes (64 and 57%) and crustaceans (24 and 34%) were the most abundant taxa in nearshore and offshore waters, respectively. The mean density of invertebrates in the nearshore waters did not differ significantly among habitats, but did vary significantly among seasons, and was greatest in summer. The mean densities of invertebrates in offshore waters did not differ significantly, however, among habitats or seasons. The compositions of nearshore benthic macroinvertebrate assemblages differed significantly among habitats and, less conspicuously, seasons. Comparisons between the faunal compositions in each pair of habitats in spring and summer were almost invariably significantly different and to a moderate extent. However, such pairwise comparisons were rarely significant in autumn and winter. Habitats A and K contained the most distinct and depauperate invertebrate fauna, comprising mainly the polychaete Capitella capitata and amphipod Corophium minor, whereas the other habitats also contained large numbers of the polychaete Ceratonereis aequisetis. In offshore waters, the composition of the benthic macroinvertebrate assemblages differed to a low to moderate degree among habitats, with habitat B containing the most distinct fauna due to large densities of C. minor. The extent of seasonal differences in these faunal compositions was small. The pattern of relative differences among nearshore habitats in terms of their benthic macroinvertebrate composition was highly correlated with that defined by both their (i) enduring environmental characteristics and (ii) non-enduring water physico-chemical and sediment characteristics in spring and/or summer. Although the faunal and enduring environmental data were not correlated at offshore sites, the fauna and non-enduring environmental variables at those sites were correlated to a moderate extent. In summary, the composition of the nearshore fish fauna at any site in Broke Inlet at any time of year can now be predicted by allocating that site to a particular habitat type on the basis of its enduring environmental characteristics. The less consistent spatial correlations between the compositions of the offshore fish fauna and benthic macroinvertebrate faunas and the enduring environmental variables largely reflected the ubiquitous nature of the majority of the abundant species representing those faunas, i.e. they are typically at least moderately abundant in all habitats and thus have no strong preferences for a particular habitat type.

Resumen

The thesis presents an analysis of faunal assemblages from late glacial and early postglacial sites in the northern Rhineland, Germany, and examines changes in environmental conditions and material culture between 13,000 - 9,000 BP. After a summary of research history into the Palaeolithic and Mesolithic of the region, the geographical, stratigraphical and absolute chronological framework is examined, and the archaeological terminology is described in its northern European context. Methods used by the study are discussed. these include quantification, spatial patterning and detailed study of the evidence for butchering methods. The main part of the thesis is provided by the study of three faunal assemblages from the sites Andernach-Martinsberg (Central Rhineland) and Bedburg-Königshoven (Lower Rhineland). Two distinct faunal complexes from the former site date to the earlier and later parts of the late glacial interstadial ("Bolling" and "Alleröd"), the Bedburg fauna dates to the Preboreal. The eruption of the Laacher see volcano (11,000 BP) has conserved late glacial sites in the Central Rhineland below deep pumice layers, giving generally excellent preservation of faunal remains. At the site Andernach-Martinsberg, two distinct faunal complexes are associated with lithic assemblages of the Magdalenian (13,000 BP) and Federmessergruppen (12,000 BP) traditions. The criteria for distinguishing the two faunal elements are first discussed. The Magdalenian fauna is characterized by species typical of arctic-continental conditions; horse, reindeer and arctic fox are the commonest species. The Final Palaeolithic (Alleröd) fauna is composed of species associated with temperate, forested conditionsred deer, elk, aurochs. The discovery of the site Bedburg-Königshoven revealed the existence of a new category of valley-bottom site previously unknown in the region. Pollen analysis and radiocarbon dating assign the archaeological level to the Preboreal. The lithic assemblage is typical for the northern European early mesolithic tradition; the fauna is dominated by the aurochs, associated with other species characterizing temperate, forested conditions. The final part of the study looks at two small late glacial faunal assemblages from the Central Rhineland. The sites Miesenheim 2 and Miesenheim 4 illustrate how human and non-human activity can be studied in detail under the excellent conditions of preservation due to the Laacher see pumice, and illustrate the potential for investigation of human subsistence activity and environmental background away from the larger sites examined by the previous part of the study.

Resumen

SUMMARY This study describes some of the processes of macroalgal rafting important for the dispersal of benthic marine invertebrates and structuring intertidal species assemblages in Irish coastal : waters, using a combination of fieldwork and laboratory analyses. A novel method for assessing the density and distribution of seaweed rafts, which takes into consideration sea state was devised as a cost effective approach for surveying drifting algae in coastal and offshore marine environments. During the development of this surver .;, metaodotegy macroalgal rafts. were collected at various locations around the lrish coastlineand species assemblages were characterised. Species richness and abundance relationships were apparentiwhen factoring in.algal carrying capacity, and analysis indicated that rafts are most likely and opportunistic platform for species for survival and potential dispersal, rather than " assemblages where.species-specific responses to raft composition will occur. The abundance of drilling rafts in the offshore environment along with the presence of intertidal invertebrates highlights· the potential importance of such drifting habitats for the survival and movement of intertidal species across large expanses of ocean. The colonisation of Idotea species onto seaweed rafts was investigated to elucidate some of the initial smaller scale processes involved with rafting organisms and to understand some potential: behavioural associations. This was especially important, for species with direct development as they are considered to have low dispersal potential. Results indicate an activ~ colonisation of rafts by Idoteaindividuals from the surrounding water column as supposed to[ust a passive marooning along with algae detaching from the shore. Finally a comparative.analysis of shores that receive high and low levels of drift material from the ocean was undertaken to compare intertidal species assemblages, to expose anr biodiversity signatures of species colonising the shore from 1he arrival of macroalgal rafts. Abundance effects of species were clearly seen in this investigation, with some species displaying significantly higher abundances on high drift shores. These along with species richness effects indicate that.the arrival of rafts to a shore may have some effect .on . intertidal , species assemblages, although exposing any consequences of drift is difficult in such a dynamic and-complex marine environment.

Resumen

Over the last twenty years attempts have been made to determine the nature of Upper Palaeolithic hunting specialization. This chapter traces assemblage structural ‘specialization’, where faunal assemblages are dominated by a single species, vs ‘diversity’, in which all recorded species are well represented, between 45,000 and 10,000 bp (Châtelperronian to Azilian), and demonstrates regularity in the archaeozoological record. It moves away from the assumption that assemblages with at least 90% of bones attributable to a single species result from specialized hunting strategies, and seeks explanations for patterns of diversification. The study also deals with the Late Glacial Maximum with its narrowing resource base and the Magdalenian of southwest France, when specialized reindeer hunting is traditionally considered of paramount importance. The chapter uses measures of diversity and evenness to quantify variation observed through time, highlighting a peak in single-species exploitation during the Middle Upper Palaeolithic. Finally, interpretations are offered for future consideration.

Resumen

The first human populations colonized the Bismarck Archipelago about 40,000 years ago. The zooarchaeological evidence from Buang Merabak (New Ireland) reveals that, at a first stage, hunter-gatherers only focused on the exploitation of local faunal resources, especially cave-dwelling bats and varanids. As for other Pleistocene assemblages, the contribution of fish to the diet is negligible. Introduced species appear since about 23,050 cal bp with the northern common cuscus (endemic of New Guinea), although bats still provided most of the meat consumed at the site. In later times, the cuscus dominates the assemblage, partially replacing cave-dwelling bats, and the wallaby is also introduced from New Guinea. The introduction and increasing consumption of the cuscus had major implications in terms of land use and mobility. The initial focus on cave-dwelling bats implied shorter stays at sites and required constant movements through the landscape; the shift towards cuscus consumption reduced mobility.

Resumen

Abstract The interpretation of depositional environments following sedimentological description is one of the most fundamental steps for the understanding of the vertical and lateral lithofacies groups’ distribution. This is directly linked to sequence stratigraphy and reservoir quality heterogeneity. Despite its importance, many interpretative lithofacies association schemes fail to capture, in a clear, systematic and flexible way, the key environmental features affecting the depositional fabrics’ distribution and their associated reservoir quality. This is especially true in carbonate systems, where the reservoir quality evaluation is complicated by the deep interrelation between physical (i.e. hydrodynamism) and biological processes. Our innovative depositional environment scheme (DE) comprises a variety of codes relating to key depositional and environmental characteristics in a way that captures their hierarchical organisation. These codes comprise groups of lithofacies interpreted to be genetically related, which provide metre-scale information commonly correlatable with wireline logs, that constitute ‘building blocks’ for static depositional architecture. The carbonate DE scheme is designed to be generic and flexible and therefore can be applied to any carbonate ramp, shelf or platform setting. The DE nomenclature uses an ‘initials-type’, letter-based abbreviation coding, which provides a straightforward and accessible understanding of the interpreted depositional environments. This comprises a suite of codes organised from a large to a small(er) scale using the formula: ‘1.2’. The first uppercase abbreviation code (1) defines the environmental belt and the energy level (i.e. hydrodynamism) from the continental to the deep offshore realm. Hydrodynamism abbreviations are typically appropriate for inner/proximal settings where a wide range of energy levels may occur.The second lowercase abbreviation code (2) corresponds to qualifiers that are used to highlight subtle variations in environmental conditions favouring the development of specific faunal assemblages (e.g. Lithocodium/Bacinella or rudists) or sedimentological features (e.g. clay content, lamination). These qualifiers allow a direct link to reservoir quality variations at the stage of sedimentological coding. Where specific geobodies can be interpreted within an environmental belt (e.g. an oolitic shoal in a dominantly high-energy inner/proximal setting) a code referring to the geobody can be added as a suffix in uppercase. The hierarchical organisation of this scheme is proven to be of great value for reservoir quality analysis. This is because it allows a simple and direct visualisation of the gross environmental settings on a carbonate platform, alongside its hydrodynamism (i.e. high-energy oolitic grainstones vs low-energy argillaceous-rich mudstones). Furthermore, the qualifiers capturing argillaceous content, allochem composition and/or depositional features are extremely effective to record reservoir quality heterogeneity and enhance sweet-spot prediction.
