Evaluating the potential impact of bird predation on the SW Atlantic fiddler crab Leptuca uruguayensis
(Springer, 2019-09)
The southernmost permanent population of the fiddler crab Leptuca uruguayensis occurs along the Samborombón Bay (36°22′S, 56°45′W, Argentina), an important feeding site for many bird species, including ruddy turnstones ...
Effects of competition and egg predation on shelter use by Octopus tehuelchus females
(Inter-Research, 2013-05)
Parental care in the ocean ranges from provision to eggs and embryos to protection from predators. In particular, nest attendance has several benefits associated with relatively higher survival rates, lower vulnerability ...
Timing of nest predation events during incubation for six passerine species in the austral Chaco
(Csiro Publishing, 2018-10)
We analysed the temporal occurrence (day–night) and timing of nest predation events during incubation for six common passerine species breeding in austral Chaco, a temperate South American habitat. We recorded time of ...
Interaction between competitors and predators and its effects on morphological and behavioural defences in Scinax nasicus tadpoles
(Brill Academic Publishers, 2013)
Intra and interspecific interactions between aphidophagous ladybirds: the role of prey in predator coexistence
(Wiley Blackwell Publishing, Inc, 2017-03)
Cannibalism (CANN) and intraguild predation (IGP) may provide energy and nutrients to individuals and eliminate potential competitors. These negative competitive interactions could also affect the coexistence of predatory ...
Interactive effects of fish predation and sublethal insecticide concentrations on freshwater zooplankton communities
(Academic Press Inc Elsevier Science, 2020-06-15)
Stresses imposed by insecticides and predators are possibly the most rigorous filters to which aquatic organisms are exposed in rivers and lakes associated with agricultural lands. However, their interactive effects on ...
Avian Predation at a Southern Rockhopper Penguin colony on Staten Island, Argentina
(Springer, 2008-12)
We studied predation risk in relation to nest location and subcolony size in Southern Rockhopper Penguins (Eudyptes chrysocome chrysocome) during the chick-rearing period. Striated Caracaras (Phalcoboenus australis), the ...
Rodent seed predation on tree invader species in grassland habitats of the inland Pampa
(Springer Tokyo, 2012-03)
Woody plant invasion in grassland ecosystems is a worldwide phenomenon, and biotic interactions as competition and predation have been invoked as a possible barrier to woody encroachment in many ecosystems. We evaluated ...
The invasive freshwater bivalve Limnoperna fortunei in South America: multiannual changes in its predation and effects on associated benthic invertebrates
(Springer, 2018-07-08)
The invasive golden mussel Limnoperna fortunei is known to strongly affect benthic communities in South American freshwaters, but the evolution of these effects after the early invasion stages is poorly understood. Using ...
Use of genetic tools to assess predation on reintroduced howler monkeys (Alouatta caraya) in Northeastern Argentina
(Springer Tokyo, 2021-05)
Despite strong support from the media, the reintroduction of animals into natural environments does not always achieve its goal. Alouatta caraya is the primate species facing the greatest hunting pressure due to the illegal ...
