Diversity Gradients

Crustaceans occur from the shelf to hadal depths, but the immense environmental change that occurs along this depth gradient results in significant faunal change. One well-established pattern is the dramatic decline in biomass with depth, a result of an exponential decline in food availability. Average body size becomes smaller, despite observations of deep-sea gigantism in some crustaceans. Crustacean species tend to occupy a limited depth range, resulting in high faunal turnover. The depths of the greatest faunal turnover vary widely throughout the oceans, and there do not appear to be distinct bathymetric “zones” at ocean-wide scales. Molecular research at the species level confirms that small bathymetric changes are often more significant at promoting population differentiation than geographic distance. Observation of crustaceans in the laboratory demonstrates that the interaction between pressure and temperature is likely to act together in limiting the bathymetric range of many species. Debate continues around species richness and diversity gradients, and it remains unclear whether there are more crustacean species on the shelf compared to bathyal depths. Diversity patterns vary between taxa. Decapods are species rich on the shelf and upper slope and less so in the abyss. Isopods show high bathyal diversity, although this pattern varies between regions. For other crustaceans, it is difficult to make generalizations on diversity gradients as there are fewer studies, and results vary depending on geographic region and the method used to estimate diversity and richness. In cumaceans, amphipods. and harpacticoids, species richness is often highest on the shelf, while maximum species diversity occurs in deeper water. Food availability and temperature are good correlates for depth-diversity gradients.

Zooplankton Communities

The lakes of Chiloé Island have a high dissolved organic carbon concentration (known as “humic”) and show a connection with brackish water. They also display a high species richness of crustacean zooplankton. The aim of the present study is to characterize the potential factors that explain crustacean species richness in Chiloé Island lakes. To that purpose parameters of the abiotic environment were determined. The results of PCA performed on those data revealed the existence of three lakes with high crustacean species richness that are relatively deep, show high nitrogen concentrations, and are located at relatively high altitude. In contrast, there are two lakes with low species richness, high mineral concentration, and situated at low altitude. One of these lowland lakes gives rise to a river effluent to the sea, and it is connected to the other lake; these observations agree with the results of a performed cluster analysis. Nevertheless, the co-occurrence null model analysis revealed the absence of regulator patterns in species associations, which could be explained to the fact that many of the species occur in most of the lakes. These results are markedly different in comparison to Patagonian lakes of Argentina and Chile that have a low crustacean species number.

Lakes And Reservoirs

The influence of trophic status on the crustacean zooplankton community was investigated in lakes and reservoirs in temperate and subtropical-tropical regions. We tested if there is a consistent relationship between crustacean species richness, assemblages, and abundance and trophic indices such as total phosphorus and chlorophyll a. We also examined if these patterns differ between regions. Cumulative species richness and assemblages varied among regions. The greatest number of crustacean species was found in the temperate oligotrophic region with the largest number of lakes sampled. However, cumulative species richness was similar in temperate and subtropical–tropical regions when comparing subsets with a similar number of lakes and reservoirs. The relationships between species richness and latitude or trophic status were difficult to assess owing to imbalance among regions in number of lakes and reservoirs sampled and to biogeography and fish predation potential influences. Trophic status was associated with changes in abundance of all major crustacean zooplankton groups. Eutrophic ecosystems supported greater crustacean abundances at all latitudes. However, cladocerans and cyclopoids were more abundant in eutrophic lakes and reservoirs, whereas calanoids were more abundant in temperate oligotrophic lakes. Total phosphorus was found to be a better predictor of the biomass of major crustacean groups than chlorophyll a in all regions.

A checklist of the decapod crustacean species from the infraorders Astacidea, Thalassinidea, Polychelida, Palinura, and Anomura from the northern and northeastern (N/NE) Brazilian coast based on literature and material deposited in the carcinological collection of the Universidade Federal de Pernambuco, Recife, Brazil, is provided. The list includes marine and estuarine species reported at least once to each of the studied area, including the oceanic islands and banks along the N/NE Brazil. A total of 146 species is reported, corresponding to an increase of 32.7% when compared to the data published in Paulo Young’s Catalogue (1998). The most representative infraorder concerning number of species is Anomura, represented in N/NE Brazil by 90 species and 10 families, followed by Thalassinidea, with 36 species and 6 families, Palinura, with 14 species and 4 families and, finally, Astacidea, which comprises 6 species and 2 families. Families with highest species richness were Porcellanidae (20), Diogenidae (19), Paguridae (18) and Galatheidae (15), all of them included in the infraorder Anomura. Zoogeographic affinities regarding the species are briefly discussed
