The die-off of the long-spined sea urchin Diadema antillarum in the 1980s highlighted its crucial role as a primary grazer in tropical western Atlantic coral reefs. However, natural recovery has been slow, exacerbated by a new die-off in 2022. Interest in actively restoring D. antillarum populations …

Antipredator responses could affect nutrient intake, which could lead to nutritional deficits. However, little is known about the antipredator response of small herbivores because most are nocturnal or crepuscular and therefore very difficult to study in the field. Therefore, we experimentally assessed …

Residing atop the trophic ladder, the jaguar plays a crucial role in the functioning, stability, and resilience of neotropical forest ecosystems. They influence the entire food web and have wide-ranging effects on various ecological processes. However, jaguars are a highly at-risk and near-threatened …

Diadema sea urchins (Diadema antillarum) are important algae grazers, but restoration attempts often record low survival of restocked individuals. This article sheds light on one of the causes for unsuccessful restocking. Restocked sea urchins were monitored with time-lapse cameras for 10 days. There …

Predation risk is a major driver of the distribution of prey animals, which typically show strong responses to cues for predator presence. An unresolved question is whether naïve individuals respond to mimicked cues, and whether such cues can be used to deter prey. We investigated whether playback of …

1. We assessed the hypothesized negative correlation between the influence of multiple predators and body condition and fecundity of the European hare, from 13 areas in the Netherlands. 2. Year-round abundance of predators was estimated by hunters. We quantified predator influence as the sum of their …

Currently there is an increasing political discussion in the Netherlands about declining farmland bird populations and the appropriate measures for their protection. The Dierenbescherming (DB) thinks that the birds cannot be saved by solely removing predators and is pledging for a predation management …

We humans have characteristics of both prey and predators. As mammals, great apes are also roughly in the middle of the food chain, although technology (fire, leverage and language) has enabled us to manoeuvre ourselves upwards on our own. Digital (mass) communication technology helps us to strengthen …

This study shows that the main predation pressure in the Dutch Wadden Sea is found to be on calanoid copepods, being the main prey item of C. harengus, A. tobianus, C. edulis, A. aurita and M. leidyi. Bivalve veligers are also found to be widely ingested by predator species, with the main predators being …

Camera trap technology has galvanized the study of predator-prey ecology in wild animal communities by expanding the scale and diversity of predator-prey interactions that can be analyzed. While observational data from systematic camera arrays have informed inferences on the spatiotemporal outcomes of …
