Dietary resilience of coral reef fishes to habitat degradation
Metabarcoding of gut contents shows that two common benthic‐feeding reef fishes with different feeding stratgies—a butterflyfish (Chaetodon capistratus) and a hamlet (Hypoplectrus puella)—shift diets on degraded reefs. These shifts mirror contrasting patterns in body condition: butterflyfish showed strong individual variation, whereas condition was ...

Record phenological responses to climate change in three sympatric penguin species
This paper is impressive because we managed to monitor extensively a really difficult place to reach and operate in. We deployed 77 cameras across Antarctica and the Sub Antarctic islands to monitor three different species of penguins. We found that they are the fastest advancing vertebrates with respect to their timing of breeding.

Effects of landscape fragmentation on floodplain fishes as revealed by species–habitat networks
Abstract How species interact with habitat patches is influenced primarily by habitat configuration (e.g., connectivity) and species’ functional traits. As levels of fragmentation increase, identifying the intricate connections between these components is crucial for biodiversity conservation.

Dinámica del control biológico basado en un modelo de cadena alimenticia con tres niveles tróficos [PDF]
En esta tesis se estudia la dinámica del control biológico mediante un modelo matemático de cadena alimenticia simple de tres niveles tróficos. Este modelo matemático esta basado en un modelo depredador presa con respuesta funcional Holling tipo II razón

We examined the temporal dynamics and ecological stability of tropical forest moth communities using a unique dataset spanning 6 months before and up to 5 years after two extreme hurricanes. While abundance and richness recovered within 2 years, species composition continued to shift, indicating ongoing reassembly with a directional trajectory toward ...

Exploration Behavior Is Consistent and Associated With Foraging Behavior in Island Songbirds
We tested the neophobia threshold hypothesis in six landbird species, including four Darwin's finches. Exploration behavior was consistent over time and contexts, with species exhibiting greater foraging diversity showing higher exploratory tendencies.

Perspectivas de una producción sostenible en acuicultura multitrófica integrada (IMTA): una revisión
La acuicultura tradicional se enfrenta a serios problemas medioambientales, particularmente por el uso de grandes volúmenes de agua, con las consecuentes descargas de efluentes ricos en nutrientes inorgánicos y partículas orgánicas.
