Article
Full-text available
Biodiversity loss from deforestation may be partly offset by the expansion of secondary forests and plantation forestry in the tropics. However, our current knowledge of the value of these habitats for biodiversity conservation is limited to very few taxa, and many studies are severely confounded by methodological shortcomings. We examined the cons...

Plantations and secondary forests are becoming dominant components of many tropical forest landscapes. Yet we have an insufficient understanding of the value of these habitats for biodiversity conservation, and almost none for most arthropods in species-rich tropical forests. We sampled epigeic arachnids (Amblypygi, Araneae, Opiliones, Scorpiones,...

The global demand for different land-use practice commodities in the Amazonia is growing, and this region is increasingly affected by the impacts of land management. The aim of this study was to evaluate the influence of land-use intensification on soil spider assemblages from six different land-use systems in Colombia and Brazil. The systems were...
Article
Full-text available
Spiders’ spinning skills have fascinated mankind since ancient times. These animals owe this ability to unique appendages named spinnerets. These structures are connected to silk-producing glands and are responsible for silk extrusion and manipulation, granting spiders the ability to use the threads for functions far beyond web-building. In spite o...
Article
Spiders constitute more than 49,000 described species distributed all over the world, and all ecological environments. Their order, Araneae, is defined by a set of characteristics with no parallel among their arachnid counterparts (e.g., spinnerets, silk glands, chelicerae that inoculate venom, among others). Changes in developmental pathways often...

A academia científica está edificada sobre um profundo viés que privilegia os homens e resulta numa progressão de carreira diferenciada entre gêneros e áreas. Nas chamadas ciências duras (Ciências, Matemática, Engenharia e Tecnologia) a presença feminina domina a base da pirâmide da carreira acadêmica, mas declina a cada nível seguinte devido às di...

Resumo: A representação feminina na ciência é frequentemente explicada pela metáfora do “leaky pipeline”, onde em cada estágio da academia, há uma redução ou ausência de pesquisadoras ocupando o mais alto nível da academia, semelhante a um vazamento em um oleoduto. Várias razões para as mulheres interromperem suas carreiras científicas foram identi...
Presentation
Full-text available
This study analyses the presence of men and women in the research that formed the last arachnology congresses, scientific editorial members, reviewers, order of authorship of papers, evaluation committees, etc. This study was focused on Araneae and examined topics encompassed by studies of this order: systematic, ecology, behavior, conservation, bi...
Conference Paper
Full-text available
Las aracnólogas de la generación Y, o millennials, traen nuevas demandas al mundo académico y si destacan por su confianza, alta formación académica, ambición, objetivos profesionales definidos y conciencia de los problemas a cerca de la baja representatividad de los grupos minoritarios. Sin embargo, aún con todas estas actitudes, todavía no hay mu...

Arachnids are charismatic animals, very abundant and/or diverse in some habitats and are important components of the ecosystems of the planet and of human culture. They are mostly generalist predators, highly dependent on microclimatic conditions of their environments and with a strong relationship and even close interactions with plants. Arachnids...

Invertebrates can be sampled using any of several well-established, rapid and cost-effective methods for documenting species richness and composition. Despite their many differences, different orders of arachnids have been often sampled together in various studies. Active nocturnal search has been long considered the most efficient method for sampl...

The Neotropical genus Austrohahnia Mello-Leitão, 1942 is revised, comprising four species from Argentina. The genus is here transferred to the subfamily Hahniinae Bertkau, 1878 from Cybaeolinae Lehtinen, 1967. Austrohahnia is diagnosed by a single synapomorphy, short setae ventrally on the abdomen, in immature as well as adult stages. The type spec...

We present a list of species of spiders collected at the Pico da Neblina, the highest mountain in Brazil (Amazonas, Brazil). We sampled at six altitudes (100, 400, 860, 1,550, 2,000 and 2,400 m a.s.l.), through manual active search, during the night and with a beating tray, during the day. We obtained a total of 3,143 adult individuals, which were...

A new species of Cryptocellus Westwood, 1874 is described, based on males, females and all free-living immature stages. Cryptocellus muiraquitan sp. nov. from Juruti, Pará, Brazil, is a member of the foedus group of species and probably closely related to Cryptocellus icamiabas Tourinho & Azevedo, 2007, C. abaporu Bonaldo & Pinto-da-Rocha, 2003 and...

The effect of forest fragmentation on the abundance of the whip spiders Heterophrynus longicornis (Butler 1973) in land-bridge island fragments created by the lake formed by Tucuruí Dam, Pará, Brazil, was investigated. These fragments have been isolated for at least 23 years, on small islands that range in size from 12.9 to 91.3 ha. The abundance o...

The identification of high-performance indicator taxa that combine practical feasibility and ecological value requires an understanding of the costs and benefits of surveying different taxa. We present a generic and novel framework for identifying such taxa, and illustrate our approach using a large-scale assessment of 14 different higher taxa acro...

Project
Support Women in Arachnology is an organization that brings together female scientists working in the field of Arachnology. Our organization arose from the strong need to make known both persistent and pressing gender biases and stereotypes in our community, to advance in the scientific investigations of this bias, and to act and propose guidelines and policies to be adopted to mitigate the worrying and pervasive effects of these issues in the career of women arachnologists.
Project
One of the great challenges for evolutionary biology is to understand the genetic basis of complex phenotypes, and how they were affected by genetic changes that occurred in the distant past. In this project, we will address this question by using the silk-spinning apparatus, or spinneret, of spiders as experimental model. There is a remarkable diversity of spinneret morphology, and yet very little is known about spinneret evolution. In fact, it is surprising that the very character that defines spiders has received so little attention from evolutionary biologists. We propose an interdisciplinary approach to study spinneret genetics, evolution and development. We will test if the diversity in spinneret morphology is a result of natural selection or genetic drift by using a quantitative genetics approach. At the same time, we will compare publicly available genomic and transcriptomic data in a phylogenetic framework to search for evidence of gene selection and/or correlated patterns of gene-phenotype diversity. Candidate genes and genomic regions will be studied in detail using a combination of molecular evolution approaches in a broader phylogenetic setting. Comparisons of developmental phenotypes and gene expression will be assessed by in situ hybridization in several spiders, and using scorpions as outgroup, which lacks spinnerets. By using this integrative approach to study morphological variation and evolutionary novelties, we expect to uncover the genetic and developmental mechanisms of spiders’ silk-spinning apparatus.
