A new tool to improve the estimates of interaction rewiring considering the whole community composition

Methods in Ecology and Evolution, Volume 15, Issue 8, Page 1438-1449, August 2024.
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 ...

Apex predators can structure ecosystems through trophic cascades: Linking the frugivorous behaviour and seed dispersal patterns of mesocarnivores

Functional Ecology, Volume 38, Issue 6, Page 1407-1419, June 2024.
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 ...

Effects of protection and temperature variation on temporal stability in a marine reserve network

Conservation Biology, Volume 38, Issue 3, June 2024.
Abstract Understanding the drivers of ecosystem stability has been a key focus of modern ecology as the impacts of the Anthropocene become more prevalent and extreme. Marine protected areas (MPAs) are tools used globally to promote biodiversity and mediate anthropogenic impacts.

Uso de modelos nulos para el estudio de comunidades de crustáceos zooplanctónicos de aguas continentales chilenas

Cuadernos de investigación UNED, 2013
El zooplancton tiene una importante función en las cadenas tróficas de los ecosistemas lénticos, transfiriendo la energía de los productores primarios fotosintéticos hacia los niveles tróficos superiores.

Plant phylogenetic diversity influences arthropod communities in tropical forest restoration plots

Biotropica, Volume 56, Issue 3, May 2024.
We assessed the impact of plant phylogenetic diversity on arthropod communities in 12 experimental restoration plots with either high or low plant phylogenetic diversity. Arthropods with different feeding habits (herbivores, predators, pollinators, and detritivores) were collected after 1 and 3 years and were identified as morphospecies or operational ...

Lipid biomarkers reveal trophic relationships and energetic trade‐offs in contrasting phenotypes of the cold‐water coral Desmophyllum dianthus in Comau Fjord, Chile

Functional Ecology, Volume 38, Issue 1, Page 126-142, January 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Benthic suspension feeders like corals and sponges are important bioengineers in many marine habitats, from the shallow tropics to the depth of polar oceans. While they are generally considered opportunistic, little is known about their actual in situ diet.

Variación temporal de la dieta de Lithobates spectabilis y Lithobates zweifeli en un matorral rosetófilo del Estado de Puebla [PDF]

, 2020
"La repartición de los recursos tróficos en anuros es importante en las interacciones inter e intraespecíficas. Aunque los hábitos alimentarios en ránidos se han estudiado a diferentes niveles, son pocos los trabajos enfocados en especies simpátricas ...
