Full textGorgonians are sessile cnidarians with a three-dimensional and complex structure that plays a relevant ecological role in coastal ecosystems, providing physical habitat, refuge and food sources for other small organisms. Despite their relevance as foundation species, very few studies have addressed the ecological patterns of hosts (gorgonians) and their attendant fauna. The present study aims to analyse the temporal variability of the epifaunal assemblages associated with two of the most abundant gorgonian species from southern Portugal, Eunicella gazella and Leptogorgia lusitanica. As gorgonian populations comprise colonies of different sizes, ecological patterns of attendant assemblages were also analysed with regards to colony size (3 size classes). Replicate samples were collected in July and November 2010, March, June and August 2011 in Pedra da Greta (Algarve, Portugal). The results suggest that the gorgonian host exert a significant effect on the composition and structure of the attendant epifaunal assemblages, although most taxa were common to both hosts. Time, more than size, was found to be a main driver of the ecological patterns of these assemblages, where amphipods, molluscs and polychaetes were the more abundant and richest groups. The temporal patterns were characterized by high densities and diversity in the attendant epifaunal assemblages during spring-summer, followed by a high mortality or emigration of rare and occasional taxa, leading to a sharp decrease in the values of biodiversity and abundance indicators. During the autumnwinter period, the assemblages were mainly dominated by the resident taxa (i.e. taxa present in all sampling dates). After the peak of phytoplankton observed during this period and as the seawater temperature increased, the spring recolonization contributed to the re-establishing of rich and abundant assemblages that persisted during the summer. Therefore, temporal variability must be taken into account for the design of future biodiversity assessment studies, as different patterns may be observed depending on the sampling time.
As gorgónias são organismos sésseis que devido à sua estrutura complexa e tridimensional desempenham um papel ecológico importante nos ecossistemas costeiros, proporcionando substrato físico, local de refúgio e fonte de alimento a outros organismos. No entanto, apesar da sua importância como espécies estruturantes, poucos estudos têm tido em consideração os padrões ecológicos, tanto das gorgónias como da sua fauna associada. Este estudo tem como principal objectivo analisar os padrões temporais da fauna epibentónica de duas das gorgónias mais abundantes do sul de Portugal, Eunicella gazella e Leptogorgia lusitanica. Devido à diferença no tamanho das colónias de gorgónias presentes, os padrões ecológicos da sua fauna associada foram analisados considerando 3 classes de tamanho. Tendo como objectivo averiguar flutuações temporais, as amostras foram recolhidas em Julho e Novembro de 2010, Março, Junho e Agosto de 2011 na Pedra da Greta (Algarve). Os resultados observados, indicam que o organismo hospedeiro exerce um efeito importante na composição e estrutura da comunidade associada, ainda que a maioria dos taxa seja comum às duas gorgónias. Não obstante, com maior influência que o tamanho da colónia, a variabilidade temporal, foi considerada o principal contribuinte para a explicação dos padrões ecológicos observados na fauna associada, na qual anfípodes, moluscos e poliquetas foram os grupos mais ricos e comuns. Os padrões temporais foram caracterizados por uma elevada densidade e diversidade da epifauna no período Primavera-Verão, seguida de uma elevada mortalidade ou emigração de taxa raros ou ocasionais, resultando num decréscimo dos valores das variáveis biológicas. Durante o período Outono-Inverno, a comunidade foi maioritariamente dominada por taxa residentes (ou seja, taxa presentes em todos os períodos de amostragem). Após o aumento da abundância de fitoplâncton observado neste período e à medida que a temperatura da água aumenta, a recolonização durante a Primavera contribui para o restabelecimento da comunidade rica e abundante do Verão. Assim, a variabilidade temporal é um factor a ter em conta na elaboração de estudos de biodiversidade, visto ser provável a ocorrência de diferenças significativas durante o período de amostragem.

This study is aiming to investigate the distribution of epibenthic shrimp communities in relation to the environmental factors of their habitats in the coastal sandy bottom of southwestern Taiwan. Shrimp samples were collected from April 2002 to July 2003, with a beam trawl operated at seven stations along the coasts. Simultaneously, water temperature, salinity, dissolved oxygen were measured and sediments were collected. Particle size and organic matter of the sediments were then analyzed in the laboratory. The results of PCA analyses on these environmental factors revealed that the observations could be segregated into two groups along the PC1, representing rainy season with high temperature, low salinity and dry season with low temperature, high salinity, respectively. The observations with coarse particle (>0.125 mm), representing samples from north sites, were found to distribute in the upper part of the PC2; while those with fine particle (<0.125 mm), representing samples from south sites, distributed in the lower part. In total, 15,591 individuals of shrimp were collected, including 20 genus, 39 species. Metapenaeopsis palmensis (88.2%), Trachysalambria curvirostris (3.6%), M. barbata (3.5%) and Parapenaeopsis cornuta (1.4%) were the four dominant species. Significant differences in the spatial distribution were due to the different composition of the dominant species. Although M. palmensis was the most abundant species in most stations, its percentage abundance was the lowest at Fangliao and Jiading, where the dominant species were T. curvirostris for the former and M. barbata and P. cornuta for the latter. Species preferences for various combinations of environmental variables are responsible for shifts in the structure and overall abundance of assemblages and dictated some patterns. Higher abundances of T. curvirostris, Trachypenaeus granulosus, and Solenocera koelbeli were associated with the appearance of high temperature, low salinity and very fine sand, representing the environmental features of Fangliao and Linbian during the rainy season. Stenopus hispidus, Metapenaeus moyebi, Metapenaeus ensis and M. palmensis were abundant coinciding with low temperature, high salinity and high silt and clay that reflecting the dry season of Linyuan and Linbian waters. Metapenaeopsis dalei and M. barbata appeared in large numbers at habitats with high temperature, low salinity and coarse sand, which mainly occurred in Zouying to Jhongjhou during the rainy season. Moreover, Scyllarus rugosus and Parapenaeopsis cornuta seemed to prefer coarse sandy bottom mainly distributed from Jiading to Linyuan. Temporal fluctuations were associated with the population dynamic of the dominant species. The abundance was reduced while the M. palmensis migrated to open sea in late summer and early autumn. As the juveniles of M. palmensis and M. barbata back to the inshore waters, the abundance were increased and reached the peak in spring. Because of the limited distribution, T. curvirostris and P. cornuta were not influence the overall temporal fluctuations but the local fluctuations. Overall, temporal fluctuations act more at a specific level even structural one, and may be linked to some particular stages of the benthic shrimp life cycle, but do not significantly influence the spatial organization.

The aims of this study is to (1) establish the baseline information of the shrimp assemblages in the coastal area in order to map the biotopes, (2) elucidate how the environmental factors act on shrimp assemblages, (3) realize the reproductive season and information on the dominant species reproductive ecology and (4) combine the information on reproductive biology and hydrology to investigate the habitat usage during the life cycle history. Shrimp samples were collected twice per season from April 2002 to August 2010, with a beam trawl operated by R/V Ocean Researcher No. 3 at 10 stations, Wanggong, Taisi, Cigu, Jiading, Zouying, Jhongjhou, Linyuan, Dapeng, Linbian and Fangliao, in the western waters off Taiwan. Simultaneously, various environmental factors were also recorded by CTD. Meanwhile, we also collected the samples from fish market for reproductive biology study since January 2009 to December 2011. In total, 54,671 individual shrimp were obtained, including 12 families, 27 genera, and 53 species. Among the families, Penaeidae consisted of the most numerous species (25 species,), followed by Alpheidae (9 species) and Scyllaridae (5 species). Metapenaeopsis palmensis (49.1%), Parapenaeopsis hardwickii (29.8%), Parapeaneopsi cornuta (5.7%), Trachysalambria curvirostris (5.1%), and M. barbata (2.0%), were the numerically dominant species, contributing 91.7% of the total catches. There is significant spatial distribution in the waters off western Taiwan. The north group and south group were dominant by M. palmensis and P. hardwickii, respectively. This phenomena might be related to the year round current and water mass seasonal oscillation in the Taiwan Strait. The reproductive season of the dominant shrimp were all occur before rainy season when the water temperature exceeds 25˚C, and the juveniles were recruit after rainy season, only the larvae born in the late spawning season will successfully recruit in the dry season in September-November when the water salinity is higher than 33.5 psu, due to the low salinity and turbid water during the rainy season.

To understand the epibenthic invertebrate community on the contential shelf break of southwestern Taiwan, we had sampled along the shelf break from Yongan to southern Penghu with beam trawl. Sampling was more intensively around nature gas drill site planed by China Petroleum Corporation. Dominant species were Cnidaria and Arthropoda in this area. The distribution of dominant species was different from inshore to offshore. The composition of dominant species group of offshore area were more homogeneous than that of inshore area. The abundance of Cnidaria was positively correlated to the number of species, abundance, diversity, and richness of the sampling site. Cnidaria appeared mostly on offshore, which including Bellonella sp., Epizoanthus ramosus, Actiniaria sp., Tropidocyathus lessonii, Flabellum distinctum and Flabellum sp.. Furthermore, Parapagurus Diogenes, Actumnus sp. and Polychae sp.2 showed high co-occurrence with Cnidaria in spatial distribution. Results of multivariate analysis showed heterogeneity in community structure among inshore and offshore. Community composition of offshore can be seperated into 3 subgroups, which were western Penghu Channel, eastern Penghu Channel, and area around nature gas drill. These findings revealed a significant influence of environment condition and topography on the composition of benthic community. The dominant species of inshore area were Portunus spp. and Parapenaeopsis spp.. The dominant species of western Penghu Channel were Portunus spp., Metapenaeopsis spp., Sepia sp., and Philine sp.. The dominant species of eastern Penghu Channel were Flabellum spp., T. lessonii, Alcyonacea spp., and E. ramosus. The dominant species of area around nature gas drill were E. ramosus, Actiniaria sp., T. lessonii, and Parapagurus Diogenes.

The present study used beam trawl net to collect crabs by Ocean Researcher III at four sites, Wanggong, Taisi, Cigu and Jiading, in western waters off Taiwan from July 2006 to October 2008. In total, 3205 crabs were obtained, including 11 families, 22 genus, 41 species and 6 unknown species. Among these families, Portunidae contained the most species (21 species, 45%), followed by families Majidae (4 species, 9%), Leucosiidae (3 species, 6%) and Dorippidae (3 species, 6%). Six dominant species were Portunus hastatoides (60.1%), Portunus argentatus (13.7%), Portunus sanguinolentus (7.2%), Matuta victor (3.8%), Charybdis truncata (3.0%) and Portunus pelagicus (2.1%) contributing 89.8% of the total catch. P. sanguinolentus (35.6%), P. pelagicus (16.3%), P. hastatoides (12.0%), Calappa philargius (11.5%), P. argentatus (8.0%) and Charybdis feriatus (3.1 %) were the six dominant species (86.5%) by biomass. Spatial distributions of the benthic crabs by number were significantly different. P. argentatus was the most dominant species in Cigu, whereas in the other three stations was P. hastatoide. Among the six species, P. sanguinolentus, P. pelagicus and C. feriatus are the most important species in terms of economic value. The former appeared in large numbers in Jiading and composed 35.6% in weight of the total catch from all sites, while the latter frequently occurred in the other three sites and contributed 16.3% to the overall sample weight. Moreover, P. sanguinolentus was the dominant species in terms of weight in Jiading, but the rest of three sites dominated by P. pelagicus. P. hastatoides occurred mostly in the substrate with very fine sand. P. sanguinolentus increased in number and weight with decreasing of salinity and water depth. P. argentatus had a narrowest optimum temperature range from 24.3 to 28.3℃.
