Cave entrances are transition zones with intermediate characteristics between epigean environments, which bear lower environmental stability, and hypogean food resources. Associated to these interfaces there is a specific community, capable of exploiting its unique characteristics. This work investigated this community in Brazilian limnestone cave, identifying arthropod species composition spatial distribution, exploring relationships climatic structural environment trophic relations. An...
Abstract The ecotone zone between epigean and hypogean environments has been delimited for two limestone caves using a new method proposed herein. richness the diversity of ecotone, their similarities have also determined. ecotones were similarity matrix inner outer sectors each cave. Dona Rita's cave was estimated to be 12 m long Retiro's 16 m.

Caves pose significant challenges for mining projects, since they harbor many endemic and threatened species, must therefore be protected. Recent discussions between academia, environmental protection agencies, industry partners, have highlighted problems with the current Brazilian legislation of caves. While licensing process is long, complex cumbersome, criteria used to assign caves into conservation relevance categories are often subjective, being mainly determined by presence obligate...
Individual movements of bats are triggered by their life requirements, limited recognition the environment and risks moving, mediated habitat selection. Mining adds fragmentation heterogeneity to landscapes, with poorly understood consequences activities bats. Cave dwelling spend most cycles within caves, as they constantly forage in external contribution input organic matter caves is paramount importance subterranean biodiversity. We investigated selection cave a mosaic Amazonian forests,...
The Brazilian semiarid region has a clear distinction between the dry season, which can last up to nine months, and rainy season.Caves are connected different extents surface ecosystems, although they idealized as stable environments due their isolation.Furthermore, little is known about effects of wet seasonal variations on underground biological assemblages.Invertebrate communities were analyzed during seasons in 24 caves northeastern Brazil.We also investigated whether environmental...
The degradation of subterranean habitats is believed to represent a serious threat for the conservation obligate dwellers (troglobites), many which are short-range endemics. However, while factors influencing cave biodiversity remain largely unknown, influence surrounding landscape and patterns connectivity terrestrial troglobitic communities have never been systematically assessed. Using spatial statistics analyze most comprehensive speleological database yet available tropical caves, we...
Cross-habitat spillover may be the outcome of a process habitat loss or degradation where receiving serves as refuge for organisms. Once surface habitats are lost degraded, animals can find underground in caves. This paper is focused on testing whether taxonomic order richness inside caves positively affected by native vegetation cover surrounding caves; predicts cave community composition; and there pattern clusters delimited similarity effects animal communities. We gathered comprehensive...
ABSTRACT Amblypygids are among the main predators in ferriferous caves Carajás National Forest, state of Pará (Amazon region Brazil). One most common amblypygid species this is Heterophrynus longicornis (Butler 1873), and its frequent prey crickets family Phalangopsidae, which abundant Pará. Because they primarily predators, necrophagy by amblypygids not nature, there only two literature records bats Amblypygi. On December 11th, 2013, we observed an individual H. eating a bat carcass cave....
We report the complete mitochondrial genome sequence of Glomeridesmus spelaeus, first sequenced order Gomeridesmida. The is 14,825 pb in length and encodes 37 (13 PCGs, 2 rRNA genes, 22 tRNA) genes contains a typical AT-rich region. base composition mitogenome was A (40.1%), T (36.4%), C (15.8%), G (7.6%), with an GC content 23.5%. Our results indicated that G. spelaeus only distantly related to other Diplopoda species available genomes public databases. As broadest genetic characterization...
Plants living above and around caves represent an important, albeit poorly studied, resource within cave ecosystems. The presence of plant material (root-like structures or rhizothemes, saplings, seeds, seedlings) correlates positively with the biodiversity dwelling animals as shown for iron-ore in Carajás, Pará, Brazil. Plant collected has proven to be difficult identify by traditional botanical methods, thus this research aims provide a qualitative insight into taxonomy morphology...
Albinism is a type of deficient in melanin production could be the result genetic anomalies that are manifest as absence coloration part or entire body an organism. This chromatic disorder can affect several vertebrate species, but rarely found nature. Among bats, more than 450 cases total partial loss pigmentation have been reported. Herein we provide first report albinism for bat species Peropteryxkappleri (Chiroptera: Emballonuridae) with two such specimens being observed from iron...
Understanding the factors underpinning species abundance patterns in space and time is essential to implement effective cave conservation actions. Yet, methods employed monitor biodiversity still lack standardization, no quantitative assessment has yet tried optimize amount type of information required efficiently identify disturbances ecosystems. Using a comprehensive monitoring dataset for tropical iron caves, comprising measurements 33 target taxa surveyed across 95 caves along four...
In this study, we report the first complete mitochondrial genome of three Mesabolivar specimens found in interior N4E_0023 cave from Serra Norte (Carajás), Parauapebas (Brazil). The mitogenomes contain 14,941, 14,845 and 14,727 bp, GC content 29.41%, 31.68% 29.34%, respectively. All include 13 protein-coding genes, 17 transfer RNA (tRNA) five putative genes two ribosomal (16S 12S rRNA). We also performed a phylogenetic analysis with concatenated coding genomes showed that analyzed...
The IUCN Red List of Threatened Species contains 175 Brazilian bat species that are threatened by extinction in some degree. From this perspective, it is essential to expand the knowledge about genetic diversity vulnerable bats. Genomic sequencing can be useful generate robust and informative references, increasing resolution when analyzing relationships among populations, species, or higher taxonomic levels. In study, we sequenced characterized detail first complete mitochondrial genomes...
Abstract Trachops cirrhosus bats are especially notable for feeding on various types of preys throughout its range, including other bat species. Here we report predation events T . Natalus macrourus, a new species among wide range prey.
Abstract Albinism is a genetic disorder that causes pigmentation anomalies. Even though supposedly rare in free-living mammals, cases of albinism have been reported worldwide, particularly bats. In this article we present new case Lionycteris spurrelli Thomas, 1913. The individual, observed an Amazon region iron ore cave, Northern Brazil, was lactating female with dark-brown pelage pup.
Coleoptera presents most of the cave fauna biodiversity, with several troglobite species belonging to aquatic family Dytiscidae. However, very little is known on both genetic and genomic diversity traits Neotropical beetles. Thus, here we present complete mitochondrial genome sequence five specimens Desmopachria collected in a ferruginous from Serra dos Carajás Parauapebas (Pará, Brazil, Eastern Amazon). Besides general characteristics mitogenome analyzed specimens, their phylogenetic...
