¿Qué determina la estructura en una red trófica?

Este posteo fue proporcionado por Tomás I. Marina y Leonardo A. Saravia y cuenta la #LaHistoriaDetrasDelPaper para el artículo “Ecological network assembly: how the regional metaweb influences local food webs”,  publicado recientemente en el Journal of Animal Ecology. Leonardo es investigador principal y profesor de la Universidad Nacional de General Sarmiento (UNGS), cerca de la ciudad de Buenos Aires, aunque en las próximas semanas se mudará a … Continue reading ¿Qué determina la estructura en una red trófica?

Why do the buffalo roam? Determining what drives seasonal strategies in large mammalian herbivores

This blog post is provided by Joel O. Abraham and A. Carla Staver and tells the #StoryBehindThePaper for the paper “Seasonal strategies differ between tropical and extratropical herbivores”, which was recently published in the Journal of Animal Ecology. The idea for this project came from a project several of us worked on a few years ago, examining the responses of savanna herbivores to drought (published … Continue reading Why do the buffalo roam? Determining what drives seasonal strategies in large mammalian herbivores

Do predators create healthier prey populations?

This blog post is provided by Ellen E. Brandell and tells the #StoryBehindThePaper for the paper “Examination of the interaction between age-specific predation and chronic disease in the Greater Yellowstone Ecosystem”, which was recently published in the Journal of Animal Ecology. The debate about if and how predators kill their prey to result in “healthier” prey populations has been ongoing for the past three decades, but … Continue reading Do predators create healthier prey populations?

Long days but little time: Goslings grow faster at high latitudes

This blog post is provided by Michiel Boom and tells the #StoryBehindThePaper for the paper “Postnatal growth rate varies with latitude in range-expanding geese – the role of plasticity and day length”, which was recently published in the Journal of Animal Ecology. While some species are clearly struggling to adapt to this rapidly changing world, the barnacle goose seems to be prospering. Contrary to other … Continue reading Long days but little time: Goslings grow faster at high latitudes

Dung beetle-mammal dung interaction networks are resilient across a gradient of forest disturbance

This blog post is provided by Li Yuen Chiew and Eleanor M. Slade and tells the #StoryBehindThePaper for the paper “Tropical forest dung beetle-mammal dung interaction networks remain similar across an environmental disturbance gradient”, which was recently published in the Journal of Animal Ecology. Li Yuen Chiew: I am a conservation ecologist, whose research focuses on biodiversity conservation and ecosystem ecology, with a particular interest … Continue reading Dung beetle-mammal dung interaction networks are resilient across a gradient of forest disturbance

Finding out when rare and common species change their interactions using multi-site interaction turnover

This blog post is provided by Marie V. Henriksen and tells the #StoryBehindThePaper for the paper “A multi-site method to capture turnover in rare to common interactions in bipartite species networks”, which was recently published in the Journal of Animal Ecology. In ecological networks, species are linked by their interactions to form complex interaction networks. How species interact in these networks reveals what role they … Continue reading Finding out when rare and common species change their interactions using multi-site interaction turnover

Connections Matter: How Patterns of Habitat Connectivity Affect Population Dynamics

This blog post is provided by Paulina A. Arancibia and Peter J. Morin and tells the #StoryBehindThePaper for the paper “Network topology and patch connectivity affect dynamics in experimental and model metapopulations”, which was recently published in the Journal of Animal Ecology. Global change has increased the rate at which habitats are fragmented, increasing the creation of spatially discontinuous populations linked by migration (metapopulations). The … Continue reading Connections Matter: How Patterns of Habitat Connectivity Affect Population Dynamics

How do mesocarnivores interact in an urban environment? And how did the SARS-CoV-2 lockdown affect it?

This blog post is provided by Julie Louvrier (Twitter: @LouvrierJulie) and tells the #StoryBehindThePaper for the paper “Spatiotemporal interactions of a novel mesocarnivore community in an urban environment before and during SARS-CoV-2 lockdown”, which was recently published in the Journal of Animal Ecology. Cities represent a novel environment for wildlife species: human activities and disturbance happen during the day; a high density of buildings and … Continue reading How do mesocarnivores interact in an urban environment? And how did the SARS-CoV-2 lockdown affect it?

Climate and genomic patterns in marine fish

This blog post is provided by Alicia Dalongeville, Emilie Boulanger and Stéphanie Manel and tells the #StoryBehindThePaper for the paper “Climate differently influences the genomic patterns of two sympatric marine fish species”, which was recently published in the Journal of Animal Ecology. Boulanger and colleagues show how the genetic variation of two marine fish species is linked to climatic conditions across the Mediterranean Sea, suggesting … Continue reading Climate and genomic patterns in marine fish
