A distinct trend of decreasing biodiversity from the tropics to the poles is well-known for terrestrial organisms. This pattern, however, is less clear in marine systems. In the present study, an inverse latitudinal biodiversity pattern is reported for the asellote isopods from Argentina. Species richness is shown to be about six times higher in the Beagle Channel and southern Patagonia, i.e., south of 47°S, than north of this latitude. This high species richness of Asellota south of 47°S seems…

Biodiversity of Isopoda and Cumacea (Peracarida, Crustacea) from the Marine Protected Area Namuncurá-Burdwood Bank, South-West Atlantic
TLDR
The biodiversity of the isopods and cumaceans from Burdwood Bank is typically Magellanic, and there is little correspondence between this fauna and that from the Antarctic Peninsula and Scotia Arc.

Invertebrate diversity of the unexplored marine western margin of Australia: taxonomy and implications for global biodiversity
TLDR
It is shown that infaunal macrofauna (crustaceans and polychaetes) of the lower bathyal depth range are underrepresented among available data and documented results from Australia, and estimates of global species, however made, are based on limited data.
Marine invertebrate biodiversity from the Argentine Sea, South Western Atlantic
TLDR
No model fit was found to fit to the data, showing that the recorded species represent less than 50% of the expected marine invertebrate biodiversity for the Argentine Sea, and the relative low effort in collecting and studying new species due to economical restrictions could explain the low fraction of described species.

TLDR
This work brings novel and updated data about the diversity and distribution of spatangoids from the SWAO, including the description of C. lyrida gen. et sp.

TLDR
The diagnostic characters of the genus Neasellus are revised and besides the inclusion of the two new species herein described, a new combination for the species Pelagogonium oculatum Schultz, 1977 is proposed.

Latitudinal gradients in macroalgal biodiversity in the Southwest Atlantic between 36 and 55°S
TLDR
A database summarizing the distributional ranges of macroalgae along the coast of Argentina found a clear trend of decreasing biodiversity with decreasing latitude, suggesting an upper thermal tolerance limit for most Antarctic/sub-Antarctic seaweeds.
Biodiversity of benthic Amphipoda (Crustacea: Peracarida) in the Southwest Atlantic between 35ºS and 56ºS
The aim of this study is to provide a synthesis of the present knowledge of the benthic Amphipoda in the Southwest Atlantic between 35oS and 56oS, and between the coast of Argentina and 50oW. The…
A comparative analysis of biodiversity and distribution of shallow-water marine isopods (Crustacea : Isopoda) from polar and temperate waters in the East Pacific
TLDR
An analysis by provinces indicates that, according to the present knowledge, the highest number of species in the East Pacific is recorded in the Oregonian Province (140 species), followed by the Californian (128), Cortes (95), Magel- lan (75), Temperate-Transitional (61), Aleutian ( 61), Mexican (53), Panamic (52), Peru-Chile (43), and Arctic (15) provinces.
Mollusk species diversity in the Southeastern Pacific: why are there more species towards the pole?
The most ubiquitous and well recognized diversity pattern at large spatial scales is the latitudinal increase in species richness near the equator and decline towards the poles. Although several…
Species richness of marine Bryozoa in the continental shelf and slope off Argentina (south‐west Atlantic)
TLDR
The distribution pattern of benthic stations surveyed during the most important cruises in the area shows that the sampling effort has been biased towards southern shelf areas off Santa Cruz and Tierra del Fuego, as well as around the Malvinas (Falkland) islands.
Dissecting latitudinal diversity gradients: functional groups and clades of marine bivalves
TLDR
It is found that bivalves as a whole, and both infauna and epifauna separately, show a strong latitudinal diversity gradient that is closely related to mean sea surface temperature (SST), even in analyses of residuals and first differences, which contradicts Thorson's environmental homogeneity hypothesis.

Biodiversity of Porifera in the Southwest Atlantic between 35º S and 56º S
TLDR
Biodiversity of Porifera is weakly but significantly correlated with latitude, since stations between 50o S and 55o S were on average richer than those located off Buenos Aires Province and around the Malvinas/Falkland Islands.
Benthic biodiversity off the eastern mouth of the Strait of Magellan (Argentina, south-west Atlantic)
TLDR
A five-fold increase in biodiversity can occur at scales of tens of km, suggesting that generalizations on regional biodiversity patterns should be made with caution because of the different gears used during the collection of samples, and should be based on a thorough knowledge about the physical environment.
Marine latitudinal diversity gradients: tests of causal hypotheses.
TLDR
A database of the geographic ranges of 3,916 species of marine prosobranch gastropods living on the shelves of the western Atlantic and eastern Pacific Oceans, from the tropics to the Arctic Ocean, finds diversity gradients are strikingly similar despite many important physical and historical differences between the oceans.
