Roadkill is widely recognized as one of the primary negative effects roads on many wildlife species and also has socioeconomic impacts when they result in accidents. A comprehensive dataset roadkill locations essential to evaluate factors contributing risk enhance our comprehension its impact populations dimensions. We undertook a compilation records, encompassing both published unpublished data gathered from road surveys or opportunistic sources. GLOBAL ROADKILL DATA includes 208,570...
Abstract Aim Roads are a major threat for wildlife, degrading habitat and causing mortality via wildlife–vehicle collisions. In Latin America, the conjunction of high biodiversity rapidly expanding road network is reason concern. We introduce an approach that combines species traits preferences to describe vulnerability map areas roadkill risk. Thus, we present first assessment impacts American birds mammals. Location America. Time period 1994–2020. Major taxa studied Birds Methods compiled...
Ecuador has both high richness and endemism, which are increasingly threatened by anthropic pressures, including roads. Research evaluating the effects of roads remains scarce, making it difficult to develop mitigation plans. Here, we present first national assessment wildlife mortality on that allow us (1) estimate roadkill rates per species, (2) identify affected species areas, (3) reveal knowledge gaps. We bring together data from systematic surveys citizen science efforts a dataset with...
The rapidly expanding global road network poses threats to wildlife, including direct mortality. Given limited knowledge and resources, strategic allocation is critical. We introduce a method identify areas taxa affected by vehicle collisions as priorities study protect. illustrated using Latin America case study. In this region high biodiversity an can result in impacts from roads, yet emerging research expertise offers opportunities for action. To priority targets, we combined predicted...
Abstract Roads impact wildlife around the world; however, dedicated studies are lacking in many biodiverse areas such as Amazon. Identifying which species more often hit by vehicles and landscape road-related features promote roadkill is essential to guide future development ensure adequate mitigation actions. For six months, we monitored 240 km of roads Ecuadorian Amazon recorded 1125 dead vertebrates (149 species). Reptiles were most observed Class with 380 individuals (56 species),...
Abstract We explore the effect of roads in animal mortality within Biodiversity Hotspot with highest number endemic species vertebrates on Earth, Tropical Andes. Our objectives were to know which are killed this particularly biodiversity‐rich area and how landscape composition configuration influences roadkills. systematically looked for roadkills along that border three protected areas Ecuadorian To evaluate our hypotheses, we used correlation, logistic regression, GIS analyses. surveyed a...
Abstract Reptiles are an understudied group in road ecology, despite evidence of their high vulnerability to mortality. Recently, trait‐based models have been demonstrated be valuable tools for explaining and predicting mortality risks birds mammals. The present study aimed apply such reptiles the first time. We fitted eight random forest regression models, controlling different survey design variables, explain 782 empirical road‐kill rates Brazilian selected best‐performing model predict...
To protect biodiversity we must understand its structure and composition including the bacteria microparasites associated with wildlife, which may pose risks to human health. However, acquiring this knowledge often presents challenges, particularly in areas of high where there are many undescribed poorly studied species funding resources can be limited. A solution fill gap is sampling roadkill (animals that die on roads as a result collisions circulating vehicles). These specimens help...
Varias especies alrededor del mundo están ampliando su distribución principalmente por la perturbación antropogénica. En Ecuador, el Vaquero Brilloso, Molothrus bonariensis, se registra cada vez con más frecuencia fuera de ámbito conocido, ello, analizamos cronológicamente sus registros evidenciando una expansión altitudinal 580 m en los últimos 44 años. También ejecutamos modelamientos máxima entropía que mostraron las áreas idoneidad hábitat para M. bonariensis incrementarían bajo...
Nasuella olivacea is an endemic mammal from the Andes of Ecuador and Colombia. Due to its rarity, aspects about natural history, ecology distribution patterns are not well known, therefore, research needed generate knowledge this carnivore a first step studying suitable habitat areas. We performed Ecological Niche Models applied future climate change scenarios (2.6 8.5 RCP) determine potential in Colombia Ecuador, with current conditions; furthermore, we analysed along several land covers....
Aspects about the feeding behavior of Laughing falcon (Herpetotherescachinnans)article remain poorly investigated with scarce reports identified species ingested by this bird. Worse still, information describing how bird ingests poisonous snakes is not known. Although eats snakes, there are no on Bothropsatrox . In work, I describe predation event and analyze roads seem to be a potential hunting strategy that H.cachinnans exploit prey snakes.

Nocturnal curassows (Nothocrax urumutum) are one of the most enigmatic birds from South American rainforests. Their elusive habits and their nocturnal vocal behavior have led to generalized assumption that they differ other in presumable habits. Here, we compiled camera trap data long term projects Amazon rainforest Andes Cordillera piedmont describe temporal activity Curassows. Based on an overall sampling effort 68838 nights obtained 274 independent records activity. The results this study...
Este trabajo evalúa el efecto que tienen ciertas variables paisajísticas (ríos, tierras agropecuarias, áreas antrópicas y bosque nativo) en los patrones de presencia del mono araña, Ateles fusciceps, noroccidente ecuatoriano. Se utilizaron registros geográficos fusciceps tomados campo estudios previos. evaluó la proximidad cada variable por medio prueba T Student. Posteriormente mediante regresiones logísticas Criterio Información Akaike (AIC) se seleccionaron mejores modelos identificaron...
Studying the microbial communities within gastrointestinal tract of vertebrate species can provide insights into biodiversity, disease ecology, and conservation. Currently, we have very limited understanding composition endogenous microbiota in wildlife, particularly high biodiversity tropical areas. Knowledge is by logistical ethical challenges obtaining samples for free-living animals. Roadkill carcasses offer a largely untapped source biological material, including gut microbiota. These...
The Mountain coati Nasuella olivacea is a species of carnivorous mammal, several aspects its ecology and natural history remain unknown. In Ecuador, presence reported in high Andean forest paramo between 1,300 3,700 m a.s.l., being rare over 3,200 m. this work, I present the extension altitudinal limit for Ecuador to 3,862 a.s.l.; addition, report an event possible interaction Tremarctos ornatus N. olivacea.
