The results show that the knowledge on biodiversity in most Brazilian PAs remain scant as 71% of PAs have less than 0.01 species records per km2, and the current PA network fails to protect the majority of endemic species.
The strong influence of collection bias on biodiversity knowledge shortfalls of Brazilian terrestrial biodiversity
The knowledge on species richness, species composition and endemism in the Brazilian biodiversity is strongly biased spatially, and despite differences in sampling effort for each taxonomic group, roadside bias affected them equally.
Selecting terrestrial arthropods as indicators of small-scale disturbance: A first approach in the Brazilian Atlantic Forest
The arachnid order Schizomida in the Brazilian Atlantic Forest: a new species of Rowlandius and new records of Stenochrus portoricensis (Schizomida: Hubbardiidae)

Two species of hubbardiid microwhipscorpions (Schizomida: Hubbardiidae) are recorded from the Brazilian Atlantic Forest. Rowlandius linsduarteae sp. nov. is described and illustrated based on…
Biogeography of Amazon birds: rivers limit species composition, but not areas of endemism

The fact that major rivers coincide with breaks in species composition suggest they can act as dispersal barriers, though not necessarily for all bird taxa, and indicates a more complex picture of the Amazonian bird distribution than previously imagined.
Systematics and evolution of ground spiders revisited (Araneae, Dionycha, Gnaphosidae)

A phylogenetic analysis of Gnaphosidae genera was performed to untangle the evolutionary history of the family and the homology and evolution of structures such as the claw tuft clasper, the spinning organs and the modification of cheliceral promargin are discussed.
Delimiting Areas of Endemism through Kernel Interpolation
The Geographical Interpolation of Endemism (GIE) was demonstrated to be effective in identifying areas of endemism in multiple scales, with fuzzy edges and supported by more synendemic species than in the other methods.
Effectiveness of sampling methods and further sampling for accessing spider diversity: a case study in a Brazilian Atlantic rainforest fragment
For a better sampling of the spider community, it is suggested that a proportion of 55, 29 and 16% of total sampling hours should be dedicated to nocturnal hand collecting, pitfall traps and beating trays, respectively, in the rainy season.
Phylogenetic analysis of Micrathena and Chaetacis spiders (Araneae: Araneidae) reveals multiple origins of extreme sexual size dimorphism and long abdominal spines
The phylogenetic relationships amongst the New World spiny orb-weaving spiders Micrathena and Chaetacis were assessed through parsimony and Bayesian analyses of morphological characters, and it is indicated that ChaetACis nests within Micrathensa and is proposed as a junior synonym of MicRathena.
Phylogeny of Sicariidae spiders (Araneae: Haplogynae), with a monograph on Neotropical Sicarius
This poster presents a probabilistic model of the response of the immune system to the presence of infectious diseases, using a model derived from the Proceedings of the National Academy of Sciences (SPA).
