Balancing tracks and trees: Assessing railroad impact on Brazilian biodiversity

PLANTS, PEOPLE, PLANET, EarlyView.
The Brazilian West–East Integration Railway (FIOL) aims to boost the national economy by improving commodity transport; however, it crosses three of Brazil's most biodiverse and fragile regions: the Caatinga, Cerrado and Atlantic Forest. Using digitised plant records and land‐use analyses, our study reveals significant vegetation loss within the ...

CAATINGA DO CARIRI PARAIBANO

Geonomos, 2013
potencial de regeneração, porém, seus mecanismos de autodefesa tornam-se consideravelmente vulneráveis as condições que lhes são impostas. Os processos morfoclimáticos típicos do meio semi-árido, com suas estações contrastadas e as degradações antrópicas, são responsáveis por um dinamismo da vegetação em que a caatinga raquítica e rala representa um ...

What are the vector species of the Oropouche virus?

Pest Management Science, EarlyView.
Here, we review the timeline of Oropouche virus (OROV) detection in various hematophagous Diptera, from 1955 to date, including mosquitoes and midges. All vector competence experiments also are described. The results suggest that Culicoides are the primary vectors.

Phylogeny and historical biogeography of the Pachira sensu lato clade (Bombacoideae, Malvaceae) with a new infrageneric classification

TAXON, EarlyView.
Abstract We explore phylogenetic relationships within the Pachira sensu lato clade (Bombacoideae, Malvaceae), test the monophyly of the genera Eriotheca and Pachira, and investigate their biogeographic history. The Pachira s.l. clade comprises ca. 72 species that traditionally have been placed in Eriotheca and Pachira. We sampled ca. 79% of its species

Detection of Leptospira in cane toads (Rhinella jimi) from urban and rural Paraíba, Brazil

Veterinary Record, EarlyView.
Abstract Background Leptospirosis is a significant zoonosis in tropical regions, where poor sanitation and favourable climate aid its spread. Synanthropic animals such as the cane toad (Rhinella jimi), which share environments with both people and wild and domestic animals, may harbour Leptospira and contribute to urban and rural transmission cycles ...
