The high diversity of bats in the Neotropics is primarily associated with various ectoparasite species on their bodies. Interactions between these animals need to be comprehensively investigated at landscape scales, focusing on understanding the patterns of diversity of species. We sought to evaluate, througt bat captures and ectoparasite sampling,...
Human land use causes habitat loss and fragmentation, influencing host-parasite associations through changes in infestation rates, host mortality and possibly local extinction. Bat-ectoparasite interactions are an important host-parasite model possibly affected by such changes, as this system acts as both reservoirs and vectors of several pathogens...
A Bacia do Alto Paraguai (BAP) inclui a planície inundável do Pantanal e as áreas altas no entorno que drenam para o rio Paraguai, uma região de transição entre quatro grandes domínios fitofisionômicos da América do Sul – Cerrado, Chaco, Amazônia e Mata Atlântica. A fauna da região é pobre em endemismos, porém as posições central e transicional no...
Understanding biodiversity patterns as well as drivers of population declines, and range losses provides crucial baselines for monitoring and conservation. However, the information needed to evaluate such trends remains unstandardised and sparsely available for many taxonomic groups and habitats, including the cave-dwelling bats and cave ecosystems...
Environmental stability can have profound impacts on life history trait evolution in organisms, especially with respect to development and reproduction. In theory, free-living species, when subjected to relatively stable and predictable conditions over many generations, should evolve narrow niche breadths and become more specialised. In parasitic o...

Understanding factors affecting the distribution of vector-borne diseases in space and across species is of prime importance to conservation ecologists. Identifying the underlying patterns of disease requires a perspective encompassing large spatial scales. However, few studies have investigated disease ecology from a macroecological perspective. H...
Abstract.Mammalian carnivores are considered a key group in maintaining ecologicalhealth and can indicate potential ecological integrity in landscapes where they occur. Carni-vores also hold high conservation value and their habitat requirements can guide managementand conservation plans. The order Carnivora has 84 species from 8 families in the Ne...

Aim
Determine the relative influence of geographical distance, environmental differences, and host species composition on the similarity of bat fly species composition.
Location
Neotropics.
Taxon
Bats (Chiroptera: Phyllostomidae) and bat flies (Diptera: Streblidae).
Methods
Abundance data on bats and ectoparasites were obtained from published st...
New technological methods, such as rapidly developing molecular approaches, often provide new tools for scientific advances. However, these new tools are often not utilized equally across different research areas, possibly leading to disparities in progress between these areas. Here, we use empirical evidence from the scientific literature to test...
Morcegos são uma linhagem única entre os mamíferos por terem a capacidade de voo e ecolocalização. Os fósseis mais antigos, que datam do Eoceno, já exibem esses dois caracteres. Entretanto, ainda é muito discutido se o ancestral comum dos morcegos possuía ou não habilidade de ecolocalização, e quais aspectos de história de vida estariam associados...
For parasites in natural systems, the most common pattern of spatial distribution is aggregation among hosts. The main causes of such aggregation are variable exposure of hosts to parasites and heterogeneity in host susceptibility. The objective of this study was to determine if there are differences in the aggregation pattern of two species of ect...
Que as mudanças climáticas influenciam a biodiversidade e os serviços ecossistêmicos não há qualquer sombra de dúvida. Mas quais são exatamente essas influências? Existem espécies mais vulneráveis? Há espécies capazes de se adaptar? Podemos aprender com elas? Quais ecossistemas e serviços ambientais são mais afetados? Podemos evitar ou minimizar os...
The Pantanal, the world’s largest alluvial floodplain, is located in the savanna biome of South America. Chiroptera is the region’s richest order of mammals, comprising approximately 40% of mammal species. Bats play here significant ecological roles as food web connectors, and especially as pollinators and seed dispersers. In this study, we review...
Here we compile a data set comprising morphological and life history information of 279 mammal species from 39,850 individuals of 388 populations ranging from 5.83 to 29.75 decimal degrees of latitude and 34.82 to 56.73 decimal degrees of lon- gitude in the Atlantic forest of South America. We present trait information from 16,840 individ- uals of...
Measures of traits are the basis of functional biological diversity. Numerous works consider mean species-level measures of traits while ignoring individual variance within species. However, there is a large amount of variation within species and it is increasingly apparent that it is important to consider trait variation not only between species,...
RESUMO Uma listagem das espécies de Hippoboscidae, Nycteribiidae e Streblidae, seus hospedeiros e localidades no estado de Mato Grosso do Sul, baseada em dados de literatura e no acervo de coleções científicas, é apresentada. Cinquenta e três espécies são registradas, sendo Xenotrichobius noctilionis Wenzel, 1976 reportada pela primeira vez no Bras...
Ticks associated with bats have been poorly documented in the Neotropical Zoogeographical Region. In this study, a total of 1028 bats were sampled for tick infestations in the southern portion of the Brazilian Pantanal. A total of 368 ticks, morphologically identified as Ornithodoros hasei (n = 364) and O. mimon (n = 4), were collected from the fol...
We developed a framework to incorporate biodiversity information about target species based on expert knowledge into landscape metrics in order to subsidize conservation planning. Four steps make up our framework: 1) biodiversity expert consults, 2) processing and organizing the information, 3) validating the information and 4) incorporating biodiv...
Streblidae flies are specialised parasites of bat hosts, mainly phyllostomids. There is a high richness of streblids in the savannah-like Cerrado region; however, there is little quantitative data available in parasitological indices. Here, we describe the component community, prevalence and intensity of a streblid infestation on a phyllostomid bat...
Chapter 1. Batflies (Diptera: Streblidae e Nycteribiidae) from bats in the Campo Verde farm, Serra da Bodoquena National Park, MS. The objective of this study is to describe host-parasites relationship using the prevalence, abundance and mean intensities indexes. Beside, I tested the influence of sex and reproductive stage in theses indexes. A tota...
