Forest conversion into pasture selects dung beetle traits at different biological scales depending on species pool composition. [PDF]

open access: yesEcol Evol, 2023
Briefly, we assess the impacts of forest conversion on the functional diversity of dung beetles in two different regions of Brazil, considering in particular intraspecific variation. To do this we conducted standardized surveys in seven forest fragments and adjacent pastures for every region and measured fourteen traits in individuals collected in each

Prioritizing Conservation Areas for the Hyacinth Macaw (Anodorhynchus hyacinthinus) in Brazil From Low-Coverage Genomic Data. [PDF]

open access: yesEvol Appl
ABSTRACT Estimates of current genetic diversity and population connectivity are especially important for endangered species that are subject to illegal harvesting and trafficking. Genetic monitoring can also ensure that management units are sustaining viable populations, while estimating genetic structure and population dynamics can influence genetic ...

Reassessment of generic boundaries in Neotropical Chrysophylloideae (Sapotaceae): Eleven reinstated genera and narrowed circumscriptions of Chrysophyllum and Pouteria

open access: yesTAXON, Volume 72, Issue 2, Page 307-359, April 2023., 2023
Abstract Classifications of the pantropical plant family Sapotaceae based solely on morphology have historically recognized between 125 and 53 genera. Phylogenetic analyses using molecular data have repeatedly demonstrated that broad concepts of two large genera belonging to subfamily Chrysophylloideae, Chrysophyllum and Pouteria, are untenable and ...

Unlocking the evolution of abdominal specializations in Luciuranus fireflies (Coleoptera, Lampyridae)

open access: yesZoologica Scripta, Volume 51, Issue 6, Page 708-723, November 2022., 2022
Abstract Understanding the evolution of genitalic traits and their co‐evolution between sexes is at the core of Evolutionary Biology. Cross‐species reproductive trait co‐variation can be the outcome of hybrid avoidance and/or sexual selection. Although the outcome of these two phenomena will look similar, they yield distinct patterns of species co ...

Roadkill patterns in Latin American birds and mammals

open access: yesGlobal Ecology and Biogeography, Volume 31, Issue 9, Page 1756-1783, September 2022., 2022
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 and a rapidly expanding road network is reason for concern. We introduce an approach that combines species traits and habitat preferences to describe vulnerability and map ...

Commodity risk assessment of Jasminum polyanthum unrooted cuttings from Uganda

open access: yesEFSA Journal, Volume 20, Issue 5, May 2022., 2022
Abstract The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation EU/2018/2019 as ‘High risk plants, plant products and other objects’. This Scientific Opinion covers plant health risks posed by unrooted cuttings of Jasminum polyanthum that are ...

The role of agroforestry in restoring Brazil's Atlantic Forest: Opportunities and challenges for smallholder farmers

open access: yesPeople and Nature, Volume 4, Issue 2, Page 462-480, April 2022., 2022
Abstract Restoring the degraded Atlantic Forest is one of the biggest conservation challenges in Brazil. In a biome with high human presence, understanding the potential for restoration approaches, such as agroforestry, to provide benefits to smallholder farmers and biodiversity is essential in developing equitable restoration strategies.

Spatial and temporal heterogeneity in a subtropical reservoir and their effects over the benthic macroinvertebrate community

open access: yesActa Limnologica Brasiliensia, 2014
AIM: The objective of the present study was to demonstrate the influences of the environment spatial heterogeneity on benthic macroinvertebrates considering transverse and longitudinal gradients as also seasonality. METHODS: Four samplings were performed:

Richness and abundance of the cardini group of Drosophila (Diptera, Drosophilidae) in the Caatinga and Atlantic Forest biomes in northeastern Brazil

open access: yesAnais da Academia Brasileira de Ciências, 2014
Brazil has a high diversity of flies of the genus Drosophila, and part of this richness is represented by the cardini group. We analyzed the fluctuations in the richness and abundance of this group, in environments that had never previously been studied ...

Distributional patterns of the neotropical fly genus Polietina Schnabl & Dziedzicki (Diptera, Muscidae): a phylogeny-supported analysis using panbiogeographic tools

open access: yesPapéis Avulsos de Zoologia, 2005
Over the last decades, Neotropical region has been subdivided into smaller units (areas of endemism), yet these subdivisions were not necessarily based on an evolutionary perspective.
