Biogeographic regionalization of the Neotropical region: New map and shapefile

Abstract

We provide a map and shapefi le of the 57 biogeographic provinces of the Neotropical region. Recognition of these provinces is based on their endemic species, but their delimitation on the map is based on ecoregions combining climatic, geological, and biotic criteria. These provinces belong to the Antillean, Brazilian and Chacoan subregions, and the Mexican and South American transition zones. We provide a vector fi le of the biogeographical regionalization by converting the map into a polygon shapefi le and a raster fi le with all provinces.

The future scenario of an iconic tree from the Brazilian Cerrado: perspectives on Eremanthus Less. (Asteraceae) conservation

“…It is widely recognized as one of the largest biodiversity hotspots in the world due to its high species richness and index of endemism, with 44% of the total plant species and 80% of its woody plants exclusive to this environment (Lenthall et al 1999; Klink and Machado 2005). The high environmental heterogeneity of the Cerrado favours the oristic diversity of plant communities, especially through the variety of soils (latosols, cambisols, gleis, hydromorphic laterite, litholic, sands quartzous, podzolic oxisols), climates and geomorphologies ( The campos rupestres constituted one of the Cerrado physiognomies in this ecoregion, but recently it was recognized as a different and independent ecoregion and in this study Cerrado and campos rupestres will be treated as distinct phytophysiognomies, in agreement with recent ecoregion proposals (Colli-Silva et al 2019; Morrone et al 2022). Campos rupestres present remarkable topographic features with the presence of rock outcrops, promoting an endemic habitat for several species (Alves et al 2014).…”

Good news! Sampling intensity needed for accurate assessments of dung beetle diversity may be lower in the Neotropics

“…We included only those articles that met the following criteria: (1) the study should address the ecology and diversity of Scarabaeinae; (2) the study should be conducted within the Neotropics (sensu Morrone et al, 2022); (3) the study should report the abundance of collected dung beetles; (4) abundance data should be reported separately for each species, habitat, or locality; (5) each dataset should be unique, i.e., not having been used previously in a different publication.…”

“…From each selected article, we extracted the number of individuals collected by species, habitat type, and number of replicate samples collected in each habitat (n); the Scopus impact factor of the journal where and when each paper was published; the species collection method; the total number of traps per habitat; the bait type; geographic information regarding the sampling sites, including the locality, municipality, and country; the climatic season when samples were collected; and the Neotropical dominion zone (sensu Morrone et al, 2022) where the study was carried out (Supplementary Tables 1, 2). Dominions are part of a hierarchical system that categorizes geographic regions according to their extant biota (Morrone, 2014).…”

Distribution of Phloeosinus tacubayae Hopkins, 1905 (Curculionidae, Scolytinae), the Cypress Bark Beetle, and new records from potential distribution models

“…8 (ESRI 2020) using the Lambert conformal conic projection and the WGS84 geodetic datum. The current distribution of the species was described using both the states of the Mexican Republic layer and the biogeographic provinces of Mexico as proposed by Morrone (2020) and Morrone et al (2017Morrone et al ( , 2022. The latter was chosen because it combines climatic, geological, and biotic criteria .…”

“…For its description, the model was projected on the map of the biogeographic provinces of Mexico (Morrone et al 2017(Morrone et al , 2022. Based on this projection, to conduct field sampling, establish new records, and corroborate the presence of P. tacubayae in some locations, which are representative of its geographic distribution, sites with high environmental suitability were selected in the north, center, and south of its known distribution.…”
