Protected areas are a cornerstone of local, regional, and global strategies for the conservation biodiversity. However, ecological performance these areas, both in terms representation maintenance key biodiversity features, remains poorly understood. A large rapidly expanding literature bears on issues, but it is highly fragmented, principally comprises particular case studies, employs diverse array approaches. Here we provide synthetic review this work, discriminating between issues...
Abstract Pollinators play a crucial role in ecosystems globally, ensuring the seed production of most flowering plants. They are threatened by global changes and knowledge their distribution at national continental levels is needed to implement efficient conservation actions, but this still fragmented and/or difficult access. As step forward, we provide an updated list around 3000 European bee hoverfly species, reflecting current distributional status level (in form present, absent,...
A high proportion of global coverage by protected areas is composed relatively few very large (vLPAs); it therefore important to understand their contribution biological conservation. Here, using fresh analyses and a review literature, we examine five particular contentions about existing terrestrial vLPAs: that they (1) are highly biased in environmental coverage, (2) contain low numbers overall rare species, (3) make limited contributions toward meeting conservation prioritization schemes,...
Abstract Knowledge of species’ functional traits is essential for understanding biodiversity patterns, predicting the impacts global environmental changes, and assessing efficiency conservation measures. Bats are major components mammalian diversity occupy a variety ecological niches geographic distributions. However, an extensive compilation their attributes still missing. Here we present EuroBaTrait 1.0, most comprehensive up-to-date trait dataset covering 47 European bat species. The...
The InsectAI COST action will support insect monitoring and conservation at the national continental scale in order to understand counteract widespread declines. Action bring together a critical mass of researchers stakeholders image-based AI technologies direct drive research agenda, build capacity across Europe innovation application. There is mounting evidence that populations insects around world are sharp decline. Understanding trends species their drivers key knowing size challenge,...
Abstract Climate change is predicted to drive geographical range shifts that will result in changes species diversity and functional composition have potential repercussions for ecosystem functioning. However, the effect of these on (FD) remains unclear, especially mammals, specifically bats. We used distribution models a comprehensive ecological morphometrical trait database estimate how projected future climate land‐use could influence distribution, composition, FD European bat community....
According to Bergmann's and Allen's rules, climate change may drive morphological shifts in species, affecting body size appendage length. These rules predict that species colder climates tend be larger have shorter appendages improve thermoregulation. Bats are thought sensitive therefore expected respond climatic changes across space time. We conducted a phylogenetic meta‐analysis on > 27 000 forearm length (FAL) mass (BM) measurements from 20 sedentary European bat examine patterns....
Abstract Aim Coyote ( Canis latrans ) distribution in Mexico and Central America has expanded recently reaching the Yucatan peninsula, Belize Panama, probably promoted by deforestation of tropical areas. Historically, southern coyotes prior to European settlement was described as only far south central that introduction livestock favoured migration America. However, coyote fossil records Yucatan, well observational travellers during sixteenth century suggest coyote's arrival region earlier....
Abstract Aim We use data based on species checklists and geographical range maps for 3096 amphibian, 4100 bird 1878 terrestrial mammal to explore possible discrepancies in estimates of richness protected areas. predict substantial differences between checklist map smaller areas, where higher errors commission from are likely occur. also how inventories may affect assessments reserve prioritization representation.

Summary Up‐to‐date knowledge on species distribution is needed for efficient biodiversity conservation and management decision‐making. Implementing sampling strategies to identify previously unknown locations of conservation‐concern therefore a key challenge. Both structured expert judgement habitat suitability models may help target towards areas where chances find the are highest. However, practitioners often object use believe they do not result in better decisions than subjective opinion...
We studied the food habits of coyote (Canis latrans) in a tropical deciduous forest along Mexican Pacific coast during 1996 and 1997. Small mammals, chiefly Jaliscan cotton rat (Sigmodon mascotensis), were main prey items dry season. Cultivated fruits, like mango papaya, most important for coyotes wet Given importance our study area human related rat, we expect expansion populations due to deforestation forest.
Abstract The effect of an open landfill and the seasonality a tropical deciduous forest in Jalisco, Mexico, was tested on home range group size coyotes Canis latrans under Resource Dispersion Hypothesis (RDH), which proposes that social carnivores dispersion patches limited resources determines home‐range size, whereas independently, abundance affects size. predictions this study were using landfill, where food is available all year due to continuous arrival wastes are concentrated single...
Abstract Hoverflies (Syrphidae) are essential pollinators, and their severe decline jeopardizes invaluable contribution to plant diversity agricultural production. However, we know little about the dispersal abilities of hoverflies in urbanized landscapes, limiting our understanding spatiotemporal dynamics plant–pollinator systems reducing ability preserve biodiversity context global change. Previous work has not addressed how urbanization affects functional connectivity whether is a factor...
Abstract Aim To assess the relative effects of spatial features protected areas ( PA s), and their interactions, on species richness representation. Location Continental America associated islands. Methods We used a novel dataset comprising estimates for amphibians, birds mammals more than 400 s in Western Hemisphere. Using tools remote sensing imagery, we calculated four each : size, shape index, fragmentation level proximity to closest . The effect size both environmental covariates levels...
Efforts to expand protected area networks are limited by the costs of managing sites. Volunteers who donate labor help manage areas can defray these costs. However, volunteers may be willing more some than others. Understanding variation in volunteering effort would enable conservation organizations account for volunteer their strategic planning. We examined across 59 small managed Yorkshire Wildlife Trust, a regional nonprofit United Kingdom. Three surveys reveal consistent patterns areas....
Abstract The diet and pattern of food resource use by the pygmy skunk Spilogale pygmaea , an endemic threatened species western Mexico, was evaluated in tropical dry forest Chamela, Jalisco. Analysis scats ( n = 104) stomach contents 5) obtained during 1997, 1998 2000 showed that skunks fed mainly on invertebrates. Insect larvae constituted most represented item samples. During 2000, quantified comparing occurrence available prey with items found scats. Even though seem to be opportunistic...

Specifically, effect different study designs and distance metrics tested terms model convergence misspecification rates (Type I error). Methods optimisation resistance...
Abstract Population genetics is a valuable tool for assessing the impact of human‐altered landscapes on genetic connectivity in various species. However, when applied to insects, challenges arise due potentially large effective population sizes (), high dispersal capacities and recency anthropogenic impacts. This study assessed structure two pollinators across landscape Luxembourg. Samples from ashy mining bee ( Andrena cineraria , N = 201) greater fly Bombylius major, 637) were genotyped at...
Coyotes are one of the most intensively studied carnivores world. However, information on coyote ecology has been obtained from individuals living within northern portion their distribution. In southern range (Mexico and Central America), home ranges (e.g., Hernandez et al. 1993, Servin Huxley 1995) food habits 1994, Sanabria 1996) have in temperate areas or subtropical deserts scrublands. tropical areas, about coyotes is limited to diet analyses (Vaughan Rodriguez 1986, HidalgoMihart 2001),...
ABSTRACT Dry season den use by the pygmy spotted skunk Spilogale pygmaea , an endemic and threatened species of western Mexico, was evaluated at micro macrohabitat level, in tropical deciduous forest Chamela, Jalisco, Mexico.
