On the origin of Antarctic marine benthic community structure.
Climate Change and Invasibility of the Antarctic Benthos
TLDR
As sea temperatures continue to rise, the invasion of durophagous predators will modernize the shelf benthos and erode the indigenous character of marine life in Antarctica.
Anthropogenic impacts on marine ecosystems in Antarctica
TLDR
Failure to address human impacts simultaneously at all scales will lead to the degradation of Antarctic marine ecosystems and the homogenization of their composition, structure, and processes with marine ecosystems elsewhere.
Life hung by a thread: endurance of Antarctic fauna in glacial periods.
TLDR
It is argued that during the last glacial period, faunal populations in the Antarctic were limited to very few areas of local marine productivity (polynyas), because complete, multiannual sea-ice and ice shelf coverage shut down most of the Southern Ocean productivity within today's seasonal sea- ice zone.
CHALLENGING THE COLD: CRABS RECONQUER THE ANTARCTIC
TLDR
It is hypothesize that larval lecithotrophy and cold tolerance, as recently observed in Subantarctic lithodids, represent, together with other adaptations in the adults, key features among the life-history adaptations of lithidids, potentially enabling them to conquer polar ecosystems.
Reproductive biology of the crab Munida subrugosa (Decapoda: Anomura: Galatheidae) in the Beagle Channel, Argentina
TLDR
Munida subrugosa was sampled monthly from November 1997 to November 1999 in the Beagle Channel by means of an epibenthic trawl and found that females and males attained physiological maturity at 9·9 and 8·0 mm CL respectively, and males reached morphometric maturity at 24·4 mm’CL.
The Antarctic-Magellan connection: Macrobenthos ecology on the shelf and upper slope, a progress report
SUMMARY: Ecological work carried out on the Antarctic and Magellan shelves since the first IBMANT conference held at the UMAG, Punta Arenas in 1997 is summarized to identify areas where progress has
Genetic homogeneity and circum-Antarctic distribution of two benthic shrimp species of the Southern Ocean, Chorismus antarcticus and Nematocarcinus lanceopes
TLDR
Signs of a population expansion in the late Pleistocene hinting at an impact of large-scale glaciations in particular on the shallow-water shrimp Chorismus antarcticus are found, supporting a (re)colonization and demographic expansion of this shrimp species in response to climate oscillation.
Developmental trade-offs in Subantarctic meroplankton communities and the enigma of low decapod diversity in high southern latitudes
TLDR
The impoverished Antarctic decapod fauna, with only a few representatives of caridean shrimp species left, may be related to the lack in flexibility of reptant decapods in distributing energy resources between adults and their offspring, which would allow abbreviated planktotrophic larval development.
The use of stress‐70 proteins in physiology: a re‐appraisal
TLDR
It is argued that HSP70 up‐regulation in response to stressors has been shown to be far more complex than the commonly accepted quasi‐linear relationship and requires a higher degree of validation than the majority of research currently undertakes.
