Increase in Beta Power Reflects Attentional Top-Down Modulation After Psychosocial Stress Induction
(2021)
Selective attention depends on goal-directed and stimulus-driven modulatory factors,
each relayed by different brain rhythms. Under certain circumstances, stress-related
states can change the balance between goal-directed ...
Adaptation of diet in a changed environment: Increased consumption of lobster krill Munida gregaria (Fabricius, 1793) by Argentine hake
(Wiley Blackwell Publishing, Inc, 2017-08)
A well-replicated decadal-term (2005–2014) stomach content data set was analysed in order to infer inter-annual fluctuations in the diet of the Argentine hake, Merluccius hubbsi, an opportunistic predator in the San Jorge ...
Assessing the relevance of top-down and bottom-up effects as phytoplankton structure drivers in a subtropical hypereutrophic shallow lake
(Springer, 2019-03-22)
Although several studies explain the trophic cascade in water systems, we lack knowledge about top-down–bottom-up effects on phytoplankton from eutrophic lakes. In this study, we tested the importance of trophic cascades ...
Foraging by the omnivorous crab Pachygrapsus transversus affects the structure of assemblages on sub-tropical rocky shores
(INTER-RESEARCH, 2010)
The roles of herbivory and predation in determining the structure and diversity of communities have been tested across most intertidal systems. In contrast, the importance of omnivorous consumers remains untested in many ...
Modulación Afectiva de la Flexibilidad Cognitiva en un Paradigma de Cambio de Tarea Voluntario de Doble Registro
(Universidad Católica del Maule, Facultad Ciencias de la Salud, 2023)
Controles top-down y bottom-up sobre el crecimiento de la esponja Hymeniacidon perlevis en la Bahía de San Antonio, Patagonia Argentina
La dinámica trófica es central en ecología ya que es uno de los procesos que determina la distribución y abundancia de los organismos. Se reconocen dos mecanismos que intentan explicar la estructura de las tramas tróficas, ...
Trait-mediated effects on flowers: Artificial spiders deceive pollinators and decrease plant fitness
(Ecological Soc Amer, 2014)
Controlling factors in planktonic communities over a salinity gradient in high-altitude lakes
(EDP Sciences, 2015-07)
This study aimed to determine the factors affecting plankton structure along a salinity gradient during the summer in high-altitude endorheic lakes in Catamarca Province (Argentina). During the summer 2013, eight lakes ...
Does the native predator Trophon geversianus exert top-down control on the invasive barnacle Balanus glandula on Patagonian rocky shores?
(Csiro Publishing, 2019-05)
Trophic interactions between the native gastropod predator Trophon geversianus and the invasive barnacle Balanus glandula may have facilitated the successful expansion of the barnacle along rocky intertidal coastlines in ...
