Aim We evaluated the bathymetric gradient of benthic polychaete species richness from the Chilean coast, as well as its possible underlying causes. We tested three possible hypotheses to explain the richness gradient: (1) Rapoport’s effect; (2) the mid-domain effect (MDE); and (c) the source‐sink hypothesis. Location South-eastern Pacific coast of Chile. Methods The bathymetric gradient in richness was evaluated using the reported ranges of bathymetric distribution of 498 polychaete species… Expand

Geographic evidence for source–sink dynamics in deep‐sea neogastropods of the eastern North Atlantic: an approach using nested analysis
TLDR
The results indicate that beta diversity in neogastropods is composed of two separate processes, turnover and nestedness, and that their relative importance changes with depth. Expand
Do Rapoport's Rule, Mid-Domain Effect or Environmental Factors Predict Latitudinal Range Size Patterns of Terrestrial Mammals in China?
TLDR
Latitudinal range size pattern of terrestrial mammals in China supported Rapoport's rule, though the extent of that support was strongly influenced by methodology, and the effects of climate, energy and topography were limited. Expand
PAPER An inverse latitudinal gradient of diversity of peracarid crustaceans along the Pacific Coast of South America: out of the deep south
TLDR
It is proposed that the southern region may be a source of evolutionary novelties and/or exhibit higher diversification rates and phylogenetic conservatism of latitudinal range may limit the geographic expansion of these new taxa towards the depauperated northern region. Expand
A latitudinal diversity gradient of shallow-water gorgonians (Cnidaria: Octocorallia: Alcyonacea) along the Tropical Eastern Pacific Ocean: testing for underlying mechanisms
One of the most pervasive patterns leading the distribution of life on Earth is the latitudinal diversity gradient (LDG). Considering its generality, understanding its main causes is critical toExpand
Descending into the abyss: Bathymetric patterns of diversity in decapod crustaceans shift with taxonomic level and life strategies
TLDR
It is shown for the first time that even within the same taxonomic group and geographic region different bathymetric patterns of diversity can be observed, depending on the taxonomic level and, more importantly, on the group's life strategies. Expand
Bathymetric patterns of polychaete (Annelida) species richness in the continental shelf of the Gulf of California, Eastern Pacific
Abstract The mid-domain effect was tested to evaluate the bathymetric patterns of the polychaete species richness in the Upper and Lower Gulf of California as a possible hypothesis to explain theExpand
The Rapoport effect is detected in a river system and is based on nested organization
TLDR
Nestedness analysis has revealed that the observed Rapoport effect is based on nested organization of the meta-assemblage over the river altitudinal/longitudinal gradient: a common species pool at low (but not the lowest) altitudes and nested subsets of this pool at higher altitudes, indicating that the Rapoports effect in altitudinal and bathymetric gradients in general may be based on nests. Expand
Patterns of richness of freshwater mollusks from Chile: predictions of its distribution based on null models
TLDR
This study shows that the geographical distribution of mollusc richness is mainly explained by mainly climatic and topographical environmental components, as well as by the source-sink dynamics. Expand
Can the source–sink hypothesis explain macrofaunal abundance patterns in the abyss? A modelling test
TLDR
It is found that abyssal macrofaunal populations are unlikely to be sustained solely through influx of larvae from slope sources, and local reproduction probably sustains macrofaunaal populations in relatively high-productivity abyssal areas, which must also be considered as potential larval source areas for more food-poor abyssal regions. Expand
Latitudinal concordance between biogeographic regionalization, community structure, and richness patterns: a study on the reptiles of China
TLDR
Biogeographic realms are an appropriate scale for studying macroecological patterns and Reptilian latitudinal richness patterns of China were explained by a combination of environmental factors and geometric constraints, while the latitudinal community structure patterns were greatly affected by environmental gradients.

A Source‐Sink Hypothesis for Abyssal Biodiversity
TLDR
Examining the depth ranges of deep‐sea gastropods and bivalves in the eastern and western North Atlantic shows that the abyssal molluscan fauna largely represents deeper range extensions for a subset of bathyal species, suggesting a new explanation for abyssal biodiversity. Expand
Ecology of bathyal polychaete fauna at an Arctic–Atlantic boundary (Faroe–Shetland Channel, North-east Atlantic)
TLDR
The bathymetric distribution of polychaetes and other benthos in this region appears to be intimately linked with the thermal regime, having a long-term impact (geological timescales) on the deep-water species pool and leading to local enhancement of diversity where cold- and warm-water masses meet and mix. Expand
Mid-domain models as predictors of species diversity patterns: bathymetric diversity gradients in the deep sea
TLDR
Bathymetric patterns of species diversity for gastropods, bivalves and polychaetes differ substantially from null expectations suggesting that geometric constraints do not account for diversity–depth patterns in the deep sea benthos. Expand

TLDR
Gastropod shells are used as a source of information about both their ecological and their evolutionary functions in generating bathymetric gradients of diversity and the findings suggest the importance of interacting ecological and evolutionary processes at varying spatiotemporal scales for both morphological disparity and species richness.

The mean bathymetric (depth) range of assemblages of marine fishes is negatively correlated with the depth at which the assemblage is found and negatively correlated with species richness. TheseExpand

The results indicate that the abyssal ecosystem is not one uniform habitat but is composed of many distinct regions, and diversity and trophic structure results agree with findings made by Hessler and Jumars. Expand
