Spatial abundance patterns across species' ranges have attracted intense attention in macroecology and biogeography. One key hypothesis has been that declines with geographical distance from the range centre, but tests of this idea shown effect may occur indeed only a minority cases. We explore an alternative hypothesis: abundances decline centroid habitable conditions environmental space (the ecological niche). demonstrate consistent negative abundance-ecological relationships all 11...
Conservation and management of species require basic knowledge on their geographic distribution abundance. Here, we propose a novel approach, based the theory ecological niche, to model spatial patterns white‐tailed deer Odocoileus virginianus population density in two regions central Mexico (Balsas Basin Tehuacán‐Cuicatlán Valley). We used an niche generate binary maps each region occurrence data set environmental variables. Then, centroid distributions was calculated space (niche centroid)...
Background Many authors have claimed that snakebite risk is associated with human population density, activities, and snake behavior. Here we analyzed whether environmental suitability of vipers can be used as an indicator risk. We tested several hypotheses to explain incidence, through the construction models incorporating both socioeconomic variables in Veracruz, Mexico. Methodology/Principal Findings Ecological niche modeling (ENM) was estimate potential geographic ecological...
Climate change is currently considered one of the main phenomena affecting marine species through expansion or contraction their distribution. Being ectothermic organisms, sharks family Carcharhinidae could be highly susceptible to effects climate change. These are great ecological importance, which reflected in role integrity coastal and oceanic ecosystems as top predators that act maintain stability food chain, well providing economic value fishing, consumption, ecotourism. Currently,...
Mangroves are highly productive ecosystems that provide important environmental services, but have been impacted massively in recent years by human activities. Studies of mangroves focused on their ecology and function at local or landscape scales, little has done to understand broader distributional patterns the factors determine those distributions. Species distribution models (SDMs), used estimate potential distributions hundreds species, yet no SDM studies date assessed mangrove...
Background Biological invasions rank among the most significant threats to biodiversity and ecosystems. Correlative ecological niche modeling is frequently used tools with which estimate potential distributions of invasive species. However, when areas accessible species across its native distribution do not represent full spectrum environmental conditions that can tolerate, correlative studies often underestimate fundamental niches. Methods Here, we explore utility supraspecific units...
Abstract Species abundance patterns are influenced by a myriad of factors, including habitat availability and ecological niche characteristics. However, the evidence concerning specific impact factors such as position breadth on mean maximum abundances in vertebrates at broad geographical scale remains inconclusive. In this study, we investigated influence 47 species birds belonging to Parulidae family, commonly known New World Warblers. We obtained data presence records spanning...
The Asian tiger mosquito, Aedes albopictus (Skuse) (Diptera: Culicidae), is an invasive species and a vector of numerous human pathogens, including chikungunya, dengue, yellow fever, Zika viruses. This mosquito had been reported from 36 geographic locations in Mexico by 2005, increasing to 101 2010 501 (spanning 16 states) 2016. Here we modeled the occupied niche for Ae. characterize environmental conditions related its presence, generate updated suitability maps. predictors with greatest...
For much of the twentieth century, many or most scholarly journals in biodiversity, ecology, biogeography and conservation were owned published by scientific societies made available to broader community at relatively low cost. However, past several decades have seen a dominant process commercialization publication this field, either commercial publishing firms taking over society (e.g., Evolution), publishers starting new fill "niches" that until then empty ecosystem. Diversity...
Snakebite envenoming is a set of intoxication diseases that disproportionately affect people poor socioeconomic backgrounds in tropical countries. As it highly dependent on the environment its burden expected to shift spatially with global anthropogenic environmental (climate, land use) and demographic change. The mechanisms underlying changes snakebite epidemiology are related factors snakes humans. distribution abundance change warming via their thermal tolerance, while rainfall may timing...
Hendra virus is a paramyxovirus of Australian flying fox bats. It was first detected in August 1994, after the death 20 horses and one human. Since then it has occurred regularly within portion geographical distribution all (fruit bat) species. There is, however, little understanding about which species are most likely responsible for spillover, or why spillover does not occur other areas occupied by reservoir hosts. Using ecological niche models four we were able to identify linked events...
A widespread biogeographic pattern in nature is that population abundance not uniform across the geographic range of species: most occurrence sites have relatively low numbers, whereas a few places contain orders magnitude more individuals. The Bolson tortoise Gopherus flavomarginatus endemic to small region Chihuahuan Desert Mexico, where habitat deterioration threatens this species with extinction. In study we combined field burrows counts and approach for modeling based on calculating...
Ecoepidemiological scenarios for Chagas disease transmission are complex, so vector control measures to decrease human–vector contact and prevent infection difficult implement in all geographic contexts. This study assessed the abundance patterns of two species disease: Triatoma maculata (Erichson, 1848) Rhodnius pallescens (Barber, 1932) Latin America. We modeled their potential distribution using maximum entropy algorithm implemented Maxent calculated distances niche centroid by fitting a...
Abstract The P eruvian A ndes presents a climate suitable for many species of sandfly that are known vectors leishmaniasis or bartonellosis, including L utzomyia peruensis ( D iptera: sychodidae), among others. In the present study, occurrences data u. were compiled from several items in scientific literature eru published between 1927 and 2015. Based on these data, ecological niche models constructed to predict spatial distributions using three algorithms [Support vector machine (SVM),...
The species richness of venomous snakes in Ecuador (~39 species) is among the highest world. However, until now no information exists regarding geographic patterns ophidism. In this study, we present a detailed spatial snakebite risk map which was built by stacking weighted ecological niche models 19 snake responsible for majority Ecuador’s envenomation cases. Our weights were based on proportion cases reported each local epidemiological studies. Based our analyses, identify 184 densely...
The deviation of expected relationships between taxonomic (TD), phylogenetic (PD), and functional (FD) diversity may inform about some processes (speciation, extinction, competition, migration) responsible for current biodiversity patterns. We studied the relationship different dimensions bird (TD, PD, FD) Yucatan Peninsula (YP) in a context future climate change. used ecological niche models to predict potential distribution 257 species YP estimate their TD, FD. calculated standardized...
