What drives animal responses to high severity fire? The role of functional traits

open access: yesBiological Reviews, EarlyView.
ABSTRACT Fire regimes are changing worldwide, with increases in the frequency, extent, and severity of fires posing growing risks to biodiversity. Fire severity – the degree of habitat alteration following fire – strongly influences both immediate survival and long‐term recovery of fauna.

Economic evaluation of supplementation with Canavalia brasiliensis CIAT 17009 in a Colombian dual-purpose cattle system

open access: yesFrontiers in Sustainable Food Systems
IntroductionIn the dual-purpose cattle systems of the Colombian Caribbean region, the grass Bothriochloa pertusa (Colosuana) is predominant. Despite its overall good performance, its productivity and quality significantly decline during dry seasons ...

Land birds on atolls: diversity, origin, and function

open access: yesBiological Reviews, EarlyView.
ABSTRACT Oceanic islands are global hotspots of avian biodiversity and endemism. Their isolation and distinct environmental conditions have uniquely shaped the evolutionary trajectories of island birds, while, in turn, land bird communities have become critical providers of ecological functions to island ecosystems.

The use of the new Tropical Forages Selection Tool by research, academia, farmers and other actors in the global Tropics [PDF]

open access: yes, 2022
The Tropical Forages Selection Tool (TF) is an open-access online knowledge system used by researchers, educators, extensionists and livestock/forage producers from Latin America, Asia and Africa to obtain expert information on 172 major forages in ...

Resolving the biome debate: ecological and palaeo‐data concur that the extensive tree‐limited grassy biomes of central and north‐western Madagascar are largely anthropogenic

open access: yesBiological Reviews, EarlyView.
ABSTRACT For millennia, human activities have transformed ecosystems globally. Determining which landscapes are predominantly anthropogenic is crucial to conservation and habitat restoration. Madagascar, a critically‐threatened biodiversity hotspot, is a prominent example.

The Impact of Sustainability Labelling on Consumers' Evaluation and Choice of Food Products: A Systematic Literature Review

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The last five years of research on sustainability labelling, reported in 175 journal articles, documents its effectiveness in increasing consumer choices of more sustainable food products. Some sustainability labels come out as stronger than others and their impact varies across products, countries, and individual consumers, depending on label

Microclimate mediates the strength and direction of avian biotic interactions

open access: yesEcography, EarlyView.
Theory predicts that the strength and direction of species interactions can shift from being competitive in benign environments toward being facilitative in stressful environments. However, the environmental context dependency of species interactions has rarely been tested in animal communities.

Human pressure, habitat heterogeneity and species traits jointly determine the level of dark diversity in coastal fish communities

open access: yesEcography, EarlyView.
Understanding how anthropogenic pressures and environmental gradients shape coastal fish communities is a central question in biogeography and marine conservation. Yet, the set of species expected to occur at a site given ecological conditions but being absent – the so‐called dark diversity – has received far less attention than observed species, even ...

Managing tropical forages field genebanks at CIAT

open access: yes, 2016
Two main reasons are identified for maintaining permanent field collections of tropical forages: (1) the inability to produce reliably sufficient and viable seed, and (2) outcrossing or highly heterozygous species where particular genotypes or ...
