The Impact

Mexico is a center of diversification for the genus Quercus, with an important number of taxa occurring along the Trans-Mexican Volcanic Belt (TMVB). However, the impact of the interaction between historical and current climatic variation and geological heterogeneity in the TMVB on the genetic and phenotypic diversification within oak species has been scarcely investigated. We used chloroplast DNA microsatellites and a geometric morphometrics analysis of leaf shape to understand differentiation between populations of Quercus deserticola Trel., which inhabits dry highlands along the TMVB. Ecological niche modeling for present-day conditions and projections into past scenarios were performed to evaluate the influence of environmental variables on the evolutionary history of the species. Results showed high genetic diversity (hS= 0.774) and high genetic structure (RST= 0.75) and the morphological subdivision of populations into two clusters, corresponding to the west/south and east/north sectors of the Q. deserticola geographic distribution. Ecological niche modeling indicated that the potential distribution of the species has remained similar from the late Pleistocene to the present. Seemingly, the phylogeographic structure of the species has been shaped by low seed-mediated gene flow and mostly local migration patterns. In turn, leaf shape is responding to climate differences either through phenotypic plasticity or local adaptation.

This study reports six new records of Convolvulaceae for Ceará state, notheastern Brazil: Ipomoea aristolochifolia G.Don, Ipomoea calyptrata Dammer, I. cynanchifolia Meisn, I. longibracteolata Sim.-Bianch. & J. R. I. Wood, I. meyeri G. Don and Jacquemontia mucronifera (Choisy) Hallier f. Of these, I. longibracteolata and I. meyeri are new records for the Atlantic Forest and Caatinga, respectively. For each species registered are provided descriptions, taxonomic and ecological comments, illustrations or photos of diagnostic characters and an ecological niche modeling analysis in northeast Brazil.

And Control

Ecological niche modeling of Triatominae bugs allow us to establish the local risk of transmission of the parasiteTrypanosoma cruzi,which causes Chagas disease.This information could help to guide health authority recommendations on infection monitoring, prevention, and control. In this study, we estimated the geographic distribution of triatomine species in Colombia and identified the relationship between landscape structure and climatic factors influencing their occurrence. A total of 2451 records of 4 triatomine species (Panstrongylus geniculatus,Rhodnius pallescens,R. prolixus, andTriatoma maculata) were analyzed.The variables that provided more information to explain the ecologic niche of these vectors were related to precipitation, altitude, and temperature. We found that the species with the broadest potential geographic distribution wereP. geniculatus,R. pallescens, andR. prolixus. In general, the models predicted the highest occurrence probability of these vectors in the eastern slope of the Eastern Cordillera, the southern region of the Magdalena valley, and the Sierra Nevada of Santa Marta.
