The growth of vines in a semi-arid tropical environment climate is heavily influenced by soil type and its chemical physical attributes. This work investigated the relationship between properties leaf nutrient absorption São Francisco Valley vineyards, northeastern Brazil, to contribute wine production. Five types soils were selected, under crops Tempranillo Syrah grape varieties conducted an espalier system. classified as Argissolo Vermelho-Amarelo (Ultisol) (PVA) with clay texture four Argissolos Amarelos (Ultisols), (PA1, PA2, PA3, PA4) medium/clayey, sandy/medium, respectively. Morphological characteristics determined grapevine field, while attributes nutritional contents analyzed laboratory. No differences found leaves during maturation. subsurface PVA had suitable distribution nutrients, pH, base sum, content, which favorable for development vines. Although PA2 has high phosphorus (436 mg kg-1) total organic carbon (25 g shallow horizons (0-10 cm), higher bulk density (~2.0 kg dm-3) lower porosity (~30%) diagnostic horizons, occured thereby jeoperdizing infiltration water into quality grapes, consequently. In general, was most promising obtaining fine-quality grapes

Abstract We report the first confirmed geographical occurrences of three species leaf-nosed bats (family Phyllostomidae) in Brazilian Caatinga, based on specimens collected semideciduous forests and rupestrian grasslands Chapada Diamantina National Park. The new records include Artibeus anderseni , A. gnomus (Stenodermatinae), Rhinophylla pumilio (Rhinophyllinae). Additionally, we expand known distribution five taxa previously recorded other sectors Caatinga but either unknown Bahia state or whose presence this region is supported by few museum specimens: Uroderma magnirostrum, Micronycteris megalotis, M. minuta, sanborni Gardnerycteris crenulata . findings highlight need for precise morphological diagnoses voucher field surveys assessments bat communities from including taxonomic revision historical records. Previous reported transitional areas between natural Atlantic Forest suggest that, with additional sampling efforts areas, could be added to inventories dry ecosystems northeastern Brazil.

A recent global systematic review of invasive plants in tropical dry forests published by Restoration Ecology has unfortunately misrepresented the forest ecosystems Tropical America, completely missing Caatinga biome, largest found on continent, as well large areas other South American forests, despite information about these having been available literature for many decades. The species list provided is compared with a purpose‐built online database to evaluate whether inaccurate representation continent reflects its completeness and usefulness scientific community restoration practitioners alike.

Abstract Urbanisation is one of the most severe land use changes with significant negative impacts on several biological groups. However, response arthropods to this process still unclear, especially in cities located arid regions, which represent an important part global urban ecosystems. Here, we examined variations abundance, richness, diversity and taxonomic composition tree crown‐dwelling 10 Brazilian semiarid climate dry forest region (Caatinga), taking into account temperature gradients number street trees along cities. We expected that cooler (in a hot range temperature) more forested would present richer, abundant distinct communities than warmer This hypothesis supported by large amount evidence showing effects local structuring communities. used method arboreal arthropod collector sample community inhabiting crowns up m height. collected total 22,911 specimens belonging two classes (Insecta Arachnida) 24 orders.
