Small wetlands have a high conservation value due to their importance as biodiversity hot spots. Despite this, they are nowadays at risk due to global change variables. We surveyed a set of seasonal wetlands located in Andean Patagonian forests which are the less studied aquatic systems. The wetlands selected presented different degrees of human im...

The ability to learn in the context of predation allows prey to respond to threats by adjusting their behavior based on specific information acquired from their current environment. Habituation is a process that allows animals to adapt to environmental changes. Very little is known about habituation in wild animals in general and there are no studi...

Feeding state of animals modulates the...
Article
Patagonia's biodiversity has been explored from many points of view, however, skin secretions of native amphibians have not been evaluated for antimicrobial peptide research until now. In this sense, Pleurodema thaul is the first amphibian specie to be studied from this large region of South America. Analysis of cDNA-encoding peptide in skin sample...
Article
Behavioral and physiological adaptive responses of animals facing chronic exposure to a single stressor may allow them to overcome its negative effects for future exposures to similar stressful situations. At chemical level, the GABAA/benzodiazepine complex is considered one of the main receptor systems involved in the modulation of stress-induced...

Recognition of predation risk from cues released from injured heterospecific could be beneficial when prey belongs to the same prey guild. Here, we performed three experiments. Experiment 1 showed that P. thaul tadpoles reduced their activity levels when exposed to conspecific injury cues, but not when exposed to amphipod injury cues. Experiment 2...

Most studies of predator-induced plasticity have focused on documenting how prey species respond to predators by modifying phenotypic traits and how traits correlate with fitness. We have previously shown that Pleurodema thaul tadpoles exposed to the dragonfly Rhionaeschna variegata responded strongly by showing morphological changes, less activity...

Movement makes prey more vulnerable to predators. Antipredator responses usually have associated costs such as reduced feeding activity, and decisions made under predation risk may be affected by the feeding state of the prey. In this study, we evaluated whether food regime influences antipredator behavioural responses of Pleurodema thaul tadpoles...

The Chacoan burrowing Frog Chacophrys pierottii (Ceratophryidae-Ceratophryinae) is an endemic species of the Chaco region in south america. there is scarce information about the biology of the species and limited information about its post-metamorphic stages. in this work we determined the diet of juvenile C. pierottii and estimated the relative im...
Article
The effect of moderate exposure to ethanol during late gestation was studied in terms of its interaction with moderate exposure during nursing from an intoxicated dam. A further issue was whether behavioral effects of ethanol, especially the enhanced ethanol intake known to occur after moderate ethanol prenatally or during nursing, depend upon tera...
Article
Ethanol experiences, during late gestation as well as during nursing, modify the behavioral dynamics of the dam/pup dyad, and leads to heightened ethanol intake in the offspring. This study focuses on: a) behavioral and metabolic changes in intoxicated dams with previous exposure to ethanol during pregnancy and b) infantile consumption of milk when...

Near-term fetuses of different mammalian species, including humans, exhibit functional sensory and learning capabilities. The neurobiological literature indicates that the unborn organism processes sensory stimuli present in the amniotic fluid, retains this information for considerable amounts of time, and is also capable of associating such stimul...

Abstract.—In the presence of predators, anuran tadpoles often exhibit behavioral plasticity, which in turn reduces predationrisk. We evaluated indirect effects of odonate larva predation on activity of Bufo arenarum tadpoles. We reared intact andtail-damaged larvae in three different predator treatments: (1) caged predators fed tadpoles; (2) caged...

Project
This project constitutes a new approach to biotic interaction, mainly because traditional ecology has tended to focus mainly on predation, competition and parasitism, even in the context of climate change. Positive interactions such as facilitation between species have been little studied, and even less in relation to climate change. This kind of interaction becomes important when it forms part of fundamental ecosystem processes, like the cycling of organic matter. The degradation of organic matter by macroinvertebrate detritivores has been widely studied in streams and rivers, but up to now this process has been little analysed in wetlands, and the role of amphibian larvae in the cycling of organic matter has been explored even less. Although ecologists have traditionally labelled tadpoles as predominantly herbivorous larval stages that constitute food for many other aquatic organisms, this view is changing. Recent studies have shown that amphibian larvae can consume much more than periphyton and phytoplankton: they also feed on organic detritus and even microorganisms such as fungi and bacteria. In addition, they take part in the recycling of organic matter in many aquatic systems, including wetlands. This project will therefore contribute new information to the theory of biotic interaction, and increase knowledge of the facilitation processes that occur between macroinvertebrates and amphibian larvae involved in organic matter cycling. Exploration of these interactions in the context of climate change is essential, since macroinvertebrates and amphibian larvae are ectotherms, which appear to be the most vulnerable organisms in this scenario. If this is so, then the phenomenon will have a direct and indirect impact on the cycling of organic matter in wetlands, altering the dynamics of these ecosystems which are already deteriorating on a global level.
