Neostregeria macropa is a crab endemic to the Bogotá Savanna, vulnerable and endangered. That is why the potential distribution and ecological aspects were established and eva...

Predators alter ecological communities by inducing changes in prey abundance and phenotypes, including elemental and isotopic composition. Climatic factors are known to often moderate predator effects on prey abundance, but few studies consider the combined effects of climate and predators on prey phenotype. We examined how altered precipitation mo...

A major challenge in evolutionary biology concerns how genetic and phenotypic variation is created and maintained. In this study, we investigated the origin(s) and evolutionary patterns of the female-limited colour polymorphism in Ischnura. This involves the presence of one to three colour morphs: one androchrome morph with coloration that resemble...

1. Imperfect mimicry may be maintained when the various components of an apose-matic signal have different salience for predators. Experimental laboratory studies provide robust evidence for this phenomenon. Yet, evidence from natural settings remains scarce. 2. We studied how natural bird predators assess multiple features in a multicom-ponent ap...

In the past decade, unoccupied aerial vehicles (UAVs or drones) have emerged as powerful tools for ecologists, and the quality and diversity of information they can reconstruct is increasing. Rocky outcrops or inselbergs are complex three-dimensional (3D) ecosystems with several spatial microhabitats that are difficult to characterize using ground-...

Changes in global and regional precipitation regimes are among the most pervasive components of climate change. Intensification of rainfall cycles, ranging from frequent downpours to severe droughts, could cause widespread, but largely unknown, alterations to trophic structure and ecosystem function. We conducted multi-site coordinated experiments...

There is growing recognition that ecosystems may be more impacted by infrequent extreme climatic events than by changes in mean climatic conditions. This has led to calls for experiments that explore the sensitivity of ecosystems over broad ranges of climatic parameter space. However, because such response surface experiments have so far been limit...
