Anthropogenic noise is an inevitable by-product of human activities. However, the potential effects of human noise on terrestrial Antarctica’s ecosystems have been understudied. Documented impacts encompass stress, alterations in behavioural patterns, auditory masking, and, in severe instances, mortality. This Perspective note aims to call attentio...

Obesity-related type II diabetes (diabesity) has increased global morbidity and mortality dramatically. Previously, the ancient drug salicylate demonstrated promise for the treatment of type II diabetes, but its clinical use was precluded due to high dose requirements. In this study, we present a nitroalkene derivative of salicylate, 5-(2-nitroethe...
RESUMEN El monitoreo de especies y comunidades es clave en la gestión de la conservación de la biodiversidad, la elaboración y la planificación de políticas de conservación. Los anfibios experimentan a nivel global una importante crisis de diversidad. En el caso de Uruguay se cuenta con un registro de 47 especies nativas, donde el 34% de ellas se e...
Obesity-related type II diabetes (diabesity) has increased global morbidity and mortality dramatically. Previously, the ancient drug salicylate demonstrated promise for the treatment of type II diabetes, but its clinical use was precluded due to high dose requirements and concomitant side effects. Recently, we showed that the nitroalkene group of u...
The hidden diversity: invertebrates of temporary ponds in Barra Grande Uruguay. Temporary ponds of Uruguay and the invertebrates that inhabit them represent relatively unexplored ecosystems, without clearreferences in relation to the diversity levels they host. In the present work we report the presence of 216 species and morphospecies of invertebr...
The uneven spatial distribution of biodiversity is a defining feature of nature. In fact, the implementation of conservation actions both locally and globally has progressively been guided by the identification of biodiversity ‘hotspots’ (areas with exceptional biodiversity). However, different regions of the world differ drastically in the availab...
The continental and marine territories of Uruguay are characterised by a rich convergence of multiple biogeographic ecoregions of the Neotropics, making this country a peculiar biodiversity spot. However, despite the biological significance of Uruguay for the South American subcontinent, the distribution of biodiversity patterns in this country rem...
Reading scientific articles is fundamental for researchers, not only to keep pace with advances in their field, but also to know those giants on whose shoulders they are standing. In this sense, Courchamp and Bradshaw (2018) recently proposed a list of 100 seminal papers deemed to be of major importance in ecology, thus providing a general 'must-re...
Evidence is growing on the ability of anurans to make immediate call adjustments in response to the propagation properties of the environment. However, our understanding of such flexibility is typically based on dichotomous stimuli (i.e. presence/absence), while its condition-dependence has been little explored. We experimentally studied the abilit...
Understanding physiological and environmental determinants of strategies of reproductive allocation is a pivotal aim in biology. Because of their high metabolic cost, properties of sexual acoustic signals may correlate with body size, temperature, and an individual’s energetic state. A quantitative theory of acoustic communication, based on the met...
Temperature is a major factor affecting population abundance and individual performance. Net reproductive rate (R0) and intrinsic rate of increase (r) differ in their response to different temperature regimes, and much of the difference is mediated by generation time (Tg). Here, we evaluate the effects of thermal mean and variability on R0, r and T...

Size–density relationships (SDRs) frequently follow a power-law relationship, with exponents that compensate for the increase in population-level metabolic demand—the energetic equivalence rule. However, these exponents present a range of values, and elucidating its methodological and biological determinants has become a main issue. So far, a restr...
The density mass–relationship (DMR) between abundance and body size is a key attribute of biodiversity organisation. The identification of the determi-nants of the DMR has consolidated as a major research area, focused on both statistical and ecological issues. Here, we advance the connection be-tween food webs and DMR, by showing how gape limitati...
The structure of the environment surrounding signal emission produces different patterns of degradation and attenuation. The expected adjustment of calls to ensure signal transmission in an environment was formalized in the acoustic adaptation hypothesis. Within this framework, most studies considered anuran calls as fixed attributes determined by...
The structure of the environment determines patterns of signal degradation and attenuation, potentially affecting communication.

The native species of amphibians and reptiles of Uruguay were categorized according to the IUCN Red List criteria. Out of 47 amphibian species, seven are listed as Critically Endangered (CR), five as Endangered (EN), one as Vulnerable (VU), three as Near Threatened (NT), and two as Data Deficient (DD); the remaining species are considered to be Lea...
