Modelling the probability of meeting IUCN Red List criteria to support reassessments

Etienne G. Henry, Luca Santini, Stuart H. M. Butchart, Manuela González‐Suárez, more

Global Change Biology > 30 > 1 > n/a - n/a

Comparative extinction risk analysis—which predicts species extinction risk from correlation with traits or geographical characteristics—has gained research attention as a promising tool to support extinction risk assessment in the IUCN Red List of Threatened Species. However, its uptake has been very limited so far, possibly because existing models only predict a species' Red List category, without...

Prioritizing the reassessment of data‐deficient species on the IUCN Red List

Victor Cazalis, Luca Santini, Pablo M. Lucas, Manuela González‐Suárez, more

Conservation Biology > 37 > 6 > n/a - n/a

Despite being central to the implementation of conservation policies, the usefulness of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species is hampered by the 14% of species classified as data‐deficient (DD) because information to evaluate these species’ extinction risk was lacking when they were last assessed or because assessors did not appropriately account...

Global patterns and predictors of avian population density

Luca Santini, Joseph A. Tobias, Corey Callaghan, Juan Gallego‐Zamorano, more

Global Ecology and Biogeography > 32 > 7 > 1189 - 1204

Aim How population density varies across animal species in the context of environmental gradients, and associated migratory strategies, remains poorly understood. The recent influx of avian trait data and population density estimates allows these patterns to be described and explored in unprecedented detail. This study aims to identify the main macroecological drivers of population density in birds...

Savviness of prey to introduced predators

Arian D. Wallach, Daniel Ramp, Ana Benítez‐López, Eamonn I. F. Wooster, more

Conservation Biology > 37 > 2 > n/a - n/a

The prey naivety hypothesis posits that prey are vulnerable to introduced predators because many generations in slow gradual coevolution are needed for appropriate avoidance responses to develop. It predicts that prey will be more responsive to native than introduced predators and less responsive to introduced predators that differ substantially from native predators and from those newly established...

Unveiling the environmental drivers of intraspecific body size variation in terrestrial vertebrates

Erin Henry, Luca Santini, Mark A. J. Huijbregts, Ana Benítez‐López

Global Ecology and Biogeography > 32 > 2 > 267 - 280

Aim Whether intraspecific spatial patterns in body size are generalizable across species remains contentious, as well as the mechanisms underlying these patterns. Here we test several hypotheses explaining within‐species body size variation in terrestrial vertebrates including the heat balance, seasonality, resource availability and water conservation hypotheses for ectotherms, and the heat conservation,...

Bat responses to climate change: a systematic review

Francesca Festa, Leonardo Ancillotto, Luca Santini, Michela Pacifici, more

Biological Reviews > 98 > 1 > 19 - 33

Understanding how species respond to climate change is key to informing vulnerability assessments and designing effective conservation strategies, yet research efforts on wildlife responses to climate change fail to deliver a representative overview due to inherent biases. Bats are a species‐rich, globally distributed group of organisms that are thought to be particularly sensitive to the effects...

The impacts of linear infrastructure on terrestrial vertebrate populations: A trait‐based approach

Melinda M. J. Jonge, Juan Gallego‐Zamorano, Mark A. J. Huijbregts, Aafke M. Schipper, more

Global Change Biology > 28 > 24 > 7217 - 7233

While linear infrastructures, such as roads and power lines, are vital to human development, they may also have negative impacts on wildlife populations up to several kilometres into the surrounding environment (infrastructure‐effect zones, IEZs). However, species‐specific IEZs are not available for the vast majority of species, hampering global assessments of infrastructure impacts on wildlife. Here,...

Time‐lagged effects of habitat fragmentation on terrestrial mammals in Madagascar

Maarten J. E. Broekman, Jelle P. Hilbers, Aafke M. Schipper, Ana Benítez‐López, more

Conservation Biology > 36 > 5 > n/a - n/a

Biodiversity is severely threatened by habitat destruction. As a consequence of habitat destruction, the remaining habitat becomes more fragmented. This results in time‐lagged population extirpations in remaining fragments when these are too small to support populations in the long term. If these time‐lagged effects are ignored, the long‐term impacts of habitat loss and fragmentation will be underestimated...

The role of artificial light at night and road density in predicting the seasonal occurrence of nocturnally migrating birds

Frank A. La Sorte, Alison Johnston, Amanda D. Rodewald, Daniel Fink, more

Diversity and Distributions > 28 > 5 > 992 - 1009

Aim Artificial light at night (ALAN) and roads are known threats to nocturnally migrating birds. How associations with ALAN and roads are defined in combination for these species at the population level across the full annual cycle has not been explored. Location Western Hemisphere. Methods We estimated range‐wide exposure, predictor importance and the prevalence of positive associations with...

Population density estimates for terrestrial mammal species

Luca Santini, Ana Benítez‐López, Carsten F. Dormann, Mark A. J. Huijbregts, more

Global Ecology and Biogeography > 31 > 5 > 978 - 994

Aim Population density is a key parameter in ecology and conservation, and estimates of population density are required for a wide variety of applications in fundamental and applied ecology. Yet, in terrestrial mammals these data are available for only a minority of species, and their availability is taxonomically and geographically biased. Here, we provide the most plausible predictions of average...

Assessing short and long‐term variations in diversity, timing and body condition of frugivorous birds

María Campo‐Celada, Pedro Jordano, Ana Benítez‐López, Carlos Gutiérrez‐Expósito, more

Oikos > 2022 > 2 > n/a - n/a

Seed dispersal by frugivorous bird species involves a fine temporal tuning between fruiting plants and birds. However, this interaction may be severely threatened by anthropogenic climate and land‐use change, which may result in phenological mismatches and pervasive ecological consequences for avian communities. In this study, we evaluate changes at long (~40 years) and short‐time (seasonal) spans...

Trait‐based projections of climate change effects on global biome distributions

Coline C.F. Boonman, Mark A.J. Huijbregts, Ana Benítez‐López, Aafke M. Schipper, more

Diversity and Distributions > 28 > 1 > 25 - 37

Aim Climate change will likely modify the global distribution of biomes, but the magnitude of change is debated. Here, we followed a trait‐based, statistical approach to model the influence of climate change on the global distribution of biomes. Location Global. Methods We predicted the global distribution of plant community mean specific leaf area (SLA), height and wood density as a function...

A data‐driven geospatial workflow to map species distributions for conservation assessments

Ruben Dario Palacio, Pablo Jose Negret, Jorge Velásquez‐Tibatá, Andrew P. Jacobson, more

Diversity and Distributions > 27 > 12 > 2559 - 2570

Aim Species distribution maps are essential for assessing extinction risk and guiding conservation efforts. However, most come sourced as expert‐drawn range maps with known issues of accuracy or are developed with overly complex modelling procedures. Thus, data‐driven alternatives that are accessible and reliable are a welcome addition to the spatial conservation toolkit. Here, we developed a geospatial...

Conditional love? Co‐occurrence patterns of drought‐sensitive species in European grasslands are consistent with the stress‐gradient hypothesis

Melinda M. J. Jonge, Ana Benítez‐López, Stephan Hennekens, Luca Santini, more

Global Ecology and Biogeography > 30 > 8 > 1609 - 1620

Aim The stress‐gradient hypothesis (SGH) postulates that species interactions shift from negative to positive with increasing abiotic stress. Interactions between species are increasingly being recognized as important drivers of species distributions, but it is still unclear whether stress‐induced changes in interactions affect continental‐to‐global scale species distributions. Here, we tested whether...

Assessing the reliability of species distribution projections in climate change research

Luca Santini, Ana Benítez‐López, Luigi Maiorano, Mirza Čengić, more

Diversity and Distributions > 27 > 6 > 1035 - 1050

Aim Forecasting changes in species distribution under future scenarios is one of the most prolific areas of application for species distribution models (SDMs). However, no consensus yet exists on the reliability of such models for drawing conclusions on species’ distribution response to changing climate. In this study, we provide an overview of common modelling practices in the field and assess the...

Large carnivore expansion in Europe is associated with human population density and land cover changes

Marta Cimatti, Nathan Ranc, Ana Benítez‐López, Luigi Maiorano, more

Diversity and Distributions > 27 > 4 > 602 - 617

Aim The recent recovery of large carnivores in Europe has been explained as resulting from a decrease in human persecution driven by widespread rural land abandonment, paralleled by forest cover increase and the consequent increase in availability of shelter and prey. We investigated whether land cover and human population density changes are related to the relative probability of occurrence of three...

Habitat destruction and overexploitation drive widespread declines in all facets of mammalian diversity in the Gran Chaco

Alfredo Romero‐Muñoz, Guillermo Fandos, Ana Benítez‐López, Tobias Kuemmerle

Global Change Biology > 27 > 4 > 755 - 767

Global biodiversity is under high and rising anthropogenic pressure. Yet, how the taxonomic, phylogenetic, and functional facets of biodiversity are affected by different threats over time is unclear. This is particularly true for the two main drivers of the current biodiversity crisis: habitat destruction and overexploitation. We provide the first long‐term assessment of multifaceted biodiversity...
