Abstract:

All the currently available interspecific scented cyclamen were bred by crossing Cyclamen persicum with only a wild species, C.purpurascens. To develop cyclamen with a wider variety of fragrances, we clarified the diversity of volatile compounds emitted from the flowers of 17 wild cyclamen species. We found that 14 of the wild species emitted fragrant compounds. In particular, C. pseudibericum, C. cyprium, C. libanoticum, C. purpurascens, C. cilicium and C. alpinum emitted floral compounds, and C. mirabile emitted fruity compounds. We produced interspecific hybrids between two C. persicum cultivars and C. purpurascens (which emitted the greatest number of volatile compounds) and analysed the scent characteristics of the resulting hybrids. We found that the hybrids varied in scent characteristics, even when the same parents were crossed; for example, we obtained hybrids with various proportions of citronellol, nerol and geraniol and various ratios of floral-scented and fruity-scented compounds.

Abstract:

Utilizing the technique of DNA – DNA hybridization, we have characterized the degree of genetic variability in single-copy DNA both within and between several species of Drosophila. The results of intraspecific variation studies indicate considerable variation both for levels of nucleotide heterozygosity (estimated to be over 2%) as well as for insertions–deletions. Interspecific studies confirm this great deal of variability and further establish an extreme heterogeneity within Drosophila genomes for rates of divergence. This heterogeneity is much more extreme than that seen between exons and introns. The degree of single-copy DNA divergence generally supports phylogenetic affinities deduced from more traditional methods. However, exceptions occur where single-copy DNA divergence is not correlated with other properties such as degree of chromosomal differentiation, morphology, or ability to form interspecific hybrids. We argue that single-copy DNA divergence as measured by DNA–DNA hybridization is an accurate indicator of phylogenetic relationships and therefore sheds light on the evolution of other biological properties. Many, if not most, evolutionary tests require an accurate phylogeny of the group being studied and DNA, because of the high information content inherent within the molecule, offers the best hope of deriving true phylogenies.Key words: DNA evolution, Drosophila, molecular evolution, phylogenetics, DNA–DNA hybridization.

Abstract:

Plants emit a diverse range of biogenic volatile organic compounds (BVOCs) into the atmosphere, of which isoprene is the most abundantly emitted. Isoprene significantly affects biological and atmospheric processes, but the range of isoprene and BVOCs present in bamboos has not been well characterized. In this thesis I explore the range of isoprene emission found in bamboos and relate it to plant morphological and physiological characteristics. In addition, I measure and relate the entire suite of BVOCs present in the bamboos to their fundamental isoprene emission rate. Interspecific variation in isoprene emission documented in a comprehensive survey of bamboos. Two groups of bamboo species were measured in the greenhouse and the field. Elevated photosynthetic rate was significantly correlated with isoprene emission. In the field, dark respiration rate was highest in bamboos that made the least amount of isoprene. The total BVOC suite was significantly influenced by whether or not leaf-level isoprene emission was present. I conclude that bamboos vary with regard to physiology, morphology, and total BVOC suite and that isoprene emission is correlated with these changes, and introduce the bamboos as a novel system for studying the impacts of isoprene emission.

Abstract:

Biological invasions continue to alter the structure and functioning of ecosystems worldwide. While the vectors and pathways of establishment of Invasive species are understood, predicting the ecological changes, or impacts, these species can exert on recipient ecosystems is lacking. Using invasive freshwater amphipods as models, this thesis aimed to investigate the role of intraspecific variation and interspecific interactions in understanding and predicting invasive species' impacts. This work first looks at the inherent variation in feeding behaviour within and between populations of an invasive amphipod, and discusses the implications of such variation for the use of functional responses, or the relationship between feeding rate and prey density. in invasion ecology. Secondly, behaviours associated to dispersal and impacts, as well as parasitic profiles, are compared between two UK populations of Dikerogammarus villosus. Differences between the populations show that monitoring population level differences, including behaviour and parasitism, can inform on invasive species' spread and impacts. Thirdly, interspecific interactions are used in order to elucidate the potential impac s of Dikerogammarus haemobaphes. Two aspects in particular are highlighted: predator-prey interactions, using the comparative functional response framework, and interference competition with D. villosus in terms of habitat use. Finally. cross-ecosystem interspecilic interactions are considered and their effects on a critical ecological process: leaf litter degradation. Using two invasive/native plant pairings, the individual leaf shredding abilities of an invasive and a native amphipod are compared in a laboratory setting. While both native plant species were consumed more readily, no difference was detected between the two amphipods. However, an in situ leaf litter bag experiment showed that the indirect effect of the invasive amphipod on macroinvertebrate community diversity may modify the degradation of certain plant species. This thesis therefore provides empirical evidence of the importance of intraspecific variation and interspecific interactions for the furthering predictive ecology

Full text

Abstract:

Dental morphology and tooth shape have been used to recreate the dietary adaptations for extinct species, and thus dental variation can provide information on the relationship between fossil species and their paleoenvironments. Variation in living species with known behaviors can provide a baseline for interpreting morphology, and behavior, in the fossil record. Tooth occlusal surface outlines in hominins and non-hominin primates, and other mammals, have been used for assessments of taxonomic significance, with variability often considered as being primarily phylogenetic. Few studies have attempted to assess how diet might influence the pattern of variability in closely related species. Here the occlusal surface shape variability in anterior and postcanine maxillary dentition in primates is measured to assess whether the relationship between diet and variability is consistent. Data were collected from five non-hominin primates in a range of dietary categories, as well as two hominin species, including the derived Paranthropus robustus and a gracile australopith. Mapping a series of 50 sliding semilandmarks based on 2-D photographs using tpsDig software, occlusal surfaces were outlined. Thereafter, outline shapes were quantified using Elliptical Fourier Functional Analysis, and principle components and multivariate analyses were preformed to explore the pattern of intra and interspecific variability in occlusal outlines.These results suggest that there is not a clear relationship between dietary feeding adaptations for all categories examined and selection for larger premolars and molars, as well as smaller incisors, led to less variation in both anterior and post-canine teeth of the fossil hominin Paranthropus robustus.

Abstract:

The aim of this project was to study the population genetics of Echinostoma trivolvis, a parasitic trematode that uses multiple hosts in its lifecycle and has a significant impact on amphibian populations. Microsatellite markers were to be identified and isolated because of their highly variable nature and reported ease of use with PCR. Parasite DNA was extracted from planorbid snails from several locations within California including: Point Reyes National Seashore, Lake Tahoe, and the San Francisco Bay Area. In addition, parasite samples were obtained from Manitoba, Canada. Several microsatellites were identified and 29 PCR primers sets were designed, six of which were capable of amplifying consistently. Sequencing other published molecular markers, COl, NDl, and ITS, unveiled intriguing phylogenetic relationships and potential cryptic species. The echinostome population in central California, as a result of this project, may be much more diverse than has long been reported in the literature.

Abstract:

Understanding variation in key functional traits across gradients in high diversity systems and the ecology of community changes along gradients in these systems is crucial in light of conservation and climate change. We examined inter- and intraspecific variation in leaf mass per area (LMA) of sun and shade leaves along a 3330-m elevation gradient in Peru, and in sun leaves across a forest-savanna vegetation gradient in Brazil. We also compared LMA variance ratios (T-statistics metrics) to null models to explore internal (i.e., abiotic) and environmental filtering on community structure along the gradients. Community- weighted LMA increased with decreasing forest cover in Brazil, likely due to increased light availability and water stress, and increased with elevation in Peru, consistent with the leaf economic spectrum strategy expected in colder, less productive environments. A very high species turnover was observed along both environmental gradients, and consequently, the first source of variation in LMA was species turnover. Variation in LMA at the genus or family levels was greater in Peru than in Brazil. Using dominant trees to examine possible filters on community assembly, we found that in Brazil, internal filtering was strongest in the forest, while environmental filtering was observed in the dry savanna. In Peru, internal filtering was observed along 80% of the gradient, perhaps due to variation in taxa or interspecific competition. Environmental filtering was observed at cloud zone edges and in lowlands, possibly due to water and nutrient availability, respectively. These results related to variation in LMA indicate that biodiversity in species rich tropical assemblages may be structured by differential niche-based processes. In the future, specific mechanisms generating these patterns of variation in leaf functional traits across tropical environmental gradients should be explored.

Abstract:

Os parques eólicos estão associados a impactos em diferentes grupos de animais e as aves planadoras são um dos mais afetados. Neste estudo avaliamos diferenças interespecíficas no comportamento de evitamento de aves planadoras migradoras ao cruzarem um parque eólico no Sudoeste de Portugal. Analisámos alterações de distância às turbinas e na sinuosidade dos movimentos, comparando entre períodos antes e após a construção do parque eólico. Para além de diferenças entre espécies examinámos também diferenças no uso de diferentes classes de altura. Os resultados revelam que, após a construção, (1) os movimentos das aves são mais sinuosos, (2) algumas espécies privilegiam voos acima das turbinas, (3) bandos de águias-calçadas voam a maiores distâncias do parque e (4) os abutres não demonstram evitamento. Este estudo evidencia respostas de evitamento das turbinas por parte das aves, os quais podem resultar em gastos energéticos adicionais que poderão afetar o sucesso da migração. Isto pode servir de base para a definição de medidas de mitigação em parques eólicos diferenciadas ao nível da espécie; Abstract: Wind farms are associated with impacts on different animal groups and soaring birds are one of the most affected. In this study, we assess interspecific differences in avoidance behaviours of migratory soaring bird species while crossing a windfarm in southwestern Portugal. We analysed changes in movements’ distance to turbines and linearity, comparing between periods before and after the windfarm implementation. Beside differences between species, we also examined differences in the use of height classes. The results reveal that after the construction of the wind farm (1) birds’ movements are more sinuous, (2) some species favour flights above the turbines, (3) flocks of Booted Eagles fly at greater distances from turbines and (4) vultures show no avoidance responses. Our study highlights the existence of bird avoidance responses to wind turbines, which may result in additional energy demands that might affect the migration success. This may be used as a base to define mitigation measures in windfarms at a species level.

Abstract:

Interspecific fish reproductive patterns, outputs and life cycles display the greatest variability within the vertebrates. Early stages of oogenesis can be repeated in adult fish, contrasting with mammals; the pre-set sequence of cell divisions in gametogenesis is otherwise similar and is described in detail. Most fish deposit much yolk (vitellogenesis) in developing eggs. Migrations, beach-spawning and mouth-brooding are some of the interesting variations. Fertilization is predominantly external but is internal in some groups such as chondrichthyans. The omission of annual reproduction is well established in some freshwater species and the idea that this may also be the case for marine teleosts is gaining acceptance. This should be taken into account for intensively fished species. The possible roles of external cues, hormones, pheromones and neural factors acting as ‘switches’ and coordinators in gametogenesis and reproductive behaviour are discussed.

Full text

Abstract:

Clutch size is generally considered to be one of the most important determinants of reproductive success and lifetime fitness in birds. It is also perhaps the most well-studied life-history trait in birds, though many reviews have focused on interspecific variation. Clutch size sets an upper limit on brood size, and in single-brooded species, clutch size will therefore determine the maximum annual fledgling productivity. This chapter identifies the physiological mechanisms underlying individual, phenotypic variation in clutch size. Topics discussed include individual variations in clutch size and clutch number; why clutch size varies among individuals; selection on clutch size; and physiological mechanisms of clutch-size determination.
