Unravelling negative interactions between humans, mammalian carnivores and raptors in South America
(Asociación Argentina de Ecología, 2022-08)
Human-wildlife interactions can be negative when the needs and behavior of wildlife negatively influence human goals, or vice-versa, and management of these interactions may lead to conflict. Here, we review information ...
Management of protected areas and its effect on an ecosystem function: Removal of Prosopis flexuosa seeds by mammals in argentinian drylands
(Public Library of Science, 2016-09-21)
The ecological function of animal seed dispersal depends on species interactions and can be affected by drivers such as the management interventions applied to protected areas. This study was conducted in two protected ...
Are there different vigilance strategies between types of social units in Lama guanicoe?
(Elsevier Science, 2019-07)
Group vigilance is a cooperative behaviour in social species that reduces individual risk of predation. Lama guanicoe is a social species of camelid performing cooperative vigilance, but little is known about the vigilance ...
Ants indirectly reduce the reproductive performance of a leafless shrub by benefiting aphids through predator deterrence
(Springer, 2019-12)
Ant–aphid mutualisms can generate cascade effects on the host plants, but these impacts depend on the ecological context. We studied the consequences of ant–aphid interactions on the reproductive performance of a Mediterranean ...
Lyapunov Exponent Analysis Applied to a Hyperchaotic Prey-predator Model
(Institute of Electrical and Electronics Engineers, 2013-02)
A stability analysis of strange and simple attractors of a prey-predator map is performed. An evolution of the species along generations is computed with the purpose of contrasting with more sophisticated measures of ...
Arm-wave display in a liolaemus lizard
(British Herpetological Society, 2019-07)
Lizards show a great variety of visual displays. Among them, arm-waving is a behaviour that has received little attention and its role is still controversial. Here, I analyse the armwaves of Liolaemus pacha lizards in their ...
Oomycete parasites in freshwater copepods of Patagonia: effects on survival and recruitment
(Inter-Research, 2018-07-04)
Copepods are hosts to various oomycete parasite species, but the effects of pathogens on copepod populations have rarely been studied. This study aimed to characterize oomycete infection in the freshwater copepod Parabroteas ...
Weather and agricultural intensification determine the breeding performance of a small generalist predator
(Nature, 2020-12-12)
Land-use changes due to agricultural intensification and climatic factors can affect avian reproduction. We use a top predator of agroecosystems, the American kestrel (Falco sparverius) breeding in nest boxes in Central ...
Modelling the consequence of glacier retreat on mixotrophic nanoflagellate bacterivory: a Bayesian approach
(Wiley, 2020-04)
Mixotrophic nanoflagellate bacterivory is affected by light; however, in glacially influenced lakes, glacial clay may also interfere with prey uptake. Mechanistic models based on prior quantitative hypotheses and tested ...
