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.

En los ecosistemas lóticos prístinos están presentes los hifomicetos acuáticos, que son un grupo de hongos imperfectos microscópicos responsables de la degradación del material vegetal que cae al agua, facilitando su uso en niveles tróficos superiores ...

Abstract Reciprocal relationships between fishers and marine life have been documented in Indigenous fishing contexts, but there are few case studies that describe the mechanisms of such relationships, and even fewer that explore other contexts, such as that of artisanal fishers in Latin American countries.

Determining quality of food ingested and digestibility can be helpful in understanding the mechanisms that determine trophic plasticity, which is the ability of a given species to use a more advantageous food source at a given time.

Butterfly species vary in sex‐specific sodium accumulation from larval diets
Male butterflies accumulate more sodium than females in three butterfly species, especially when larvae were exposed to high dietary sodium concentrations. Sodium bioaccumulation occurred mainly in Low Na treatments and bioexcretion was highest in females on High Na diets.

Salamander loss alters montane stream ecosystem functioning and structure through top‐down effects
Salamanders are seriously declining worldwide and, despite being important predators in both aquatic and terrestrial environments, their effects on freshwater ecosystems are virtually unknown. We demonstrated that salamander loss could alter montane stream ecosystem functioning and structure by reducing periphyton accrual, altering algal communities ...

During fall migration, avivorous raptors and avian prey co‐occur across space and time. We used a novel approach—combining eDNA metabarcoding and eBird data—to investigate predator–prey interactions between an avivorous raptor and co‐occurring avian prey species. This approach revealed prey availability and traits influence raptor‐songbird interactions

Abstract Understanding temporal dynamics in ecological networks is crucial to predict their capability to cope with global changes. Despite this, proper quantification of network dynamics still remains a challenge. Temporal dynamics are typically studied using data of interaction networks over time, through the evaluation of interaction turnover and ...

Read the free Plain Language Summary for this article on the Journal blog. Abstract Current global change scenarios demand knowledge on how anthropogenic impacts affect ecosystem functioning through changes in food web structure. Frugivorous mesocarnivores are a key link in trophic cascades because, while their abundance and behaviour are usually ...
