First laboratory insight on the behavioral rhythms of the bathyal crab Geryon longipes
(Pergamon-Elsevier Science Ltd, 2016-10)
The deep sea is the largest and at the same time least explored biome on Earth, but quantitative studies on the behavior of bathyal organisms are scarce because of the intrinsic difficulties related to in situ observations ...
Influence of the winter phytoplankton bloom on the settled material in a temperate shallow estuary
(Polish Acad Sciences Inst Oceanology, 2015-01)
The development of the phytoplankton winter bloom and the accumulation of particulate suspended matter (PSM) inside sediment collectors were assessed in the inner zone of the Bahía Blanca Estuary. The phytoplankton bloom ...
Species- and habitat-specific bioaccumulation of total mercury and methylmercury in the food web of a deep oligotrophic lake
(Elsevier, 2018-01-15)
Niche segregation between introduced and native fish in Lake Nahuel Huapi, a deep oligotrophic lake in Northwest Patagonia (Argentina), occurs through the consumption of different prey. Therefore, in this work we analyzed ...
Sublethal effects of ultraviolet radiation on crab larvae of Cyrtograpsus altimanus
(Elsevier Science, 2011-10)
Ultraviolet radiation (UVR, 280-400. nm) is known to be lethal to several aquatic species; however, more subtle, 'sublethal' effects of UVR have recently received more attention. Larvae of the crab Cyrtograpsus altimanus ...
Diatoms (Bacillariophyceae) associated with free-drifting Antarctic icebergs: taxonomy and distribution
(Springer, 2015-10)
There are several recent studies about life in relation to Antarctic icebergs. Diatom communities have been found living on submerged vertical walls of icebergs. In this study we complement and extend the taxonomic and ...
Decomposition of cattle manure and colonization by macroinvertebrates in sediment of a wetland of the Middle Paraná River
(Springer Heidelberg, 2016-09)
Purpose: The study was carried out in a wetland of the Middle Paraná River system, Argentina, in order to evaluate the processes associated with the decomposition of manure, which includes changes in chemical composition, ...
General ecology of coastal fish from the South Shetland Island and west Antarctic Peninsula areas
(Alfred Wegener Institut für Polar und Meeresforschung, 2008-10)
There is a lower diversity of Antarctic fish species on the continental shelves (139 spp) compared with other cold-water seas (> 350 spp in the North Atlantic). However, although the diversity of the notothenioids is limited ...
Effects of an invasive reef-builder polychaete on biomass and composition of estuarine macroalgae assemblages.
(Springer, 2012-06)
Invasive species can transform ecological communities. Their profound effects may alter the sources and pathways of primary production. We investigated the effects of the reef forming polychaete Ficopomatus enigmaticus ...
Population response during an Oceanic Anoxic Event: The case of Posidonotis (Bivalvia) from the Lower Jurassic of the Neuquén Basin, Argentina
(Elsevier Science, 2019-07-01)
Benthonic marine species show a wide range of biological reactions to seawater chemical changes through time, from subtle adjustments to extinction. The Early Toarcian Oceanic Anoxic Event (T-OAE) was recently recognized ...
Response of benthic fauna to experimental bottom fishing: A global meta-analysis
(Wiley Blackwell Publishing, Inc, 2018-07)
Bottom-contact fishing gears are globally the most widespread anthropogenic sources of direct disturbance to the seabed and associated biota. Managing these fishing disturbances requires quantification of gear impacts on ...
