ABSTRACT ∙ To investigate the value of water reservoirs for waterbirds in semi‐arid lands, we studied the waterbird community in semi‐arid of Paraíba, Brazil, and compared the results with other assemblages both in semi‐arid and humid regions of Neotropics. Birds were counted during 15 months in 12 reservoirs belonging to the Piranhas‐Açu River basin. We counted 4111 waterbirds and recorded 36 species. The most abundant species, such as Wattled Jacana (Jacana jacana) and Common Gallinule (Gallinula galeata), were strongly tied to aquatic vegetation. All species have wide distribution, far beyo

Abstract:
A new species of terrestrial isopod, Gabunillo aridicola sp. nov., is described from Ceará and Rio Grande do Norte States, in Karstic formations in the Brazilian semi-arid (caatinga). This genus, hitherto monotypic, was known only from Gabon. This occurrence is remarkable because very few genera of Armadillidae are known from both Afrotropics and Neotropics, and because it offers evidence of a tropical Gondwana biogeographical component.

This study aimed to recognize the floristic composition, the life form and the distribution of species of climbing plants occurring on 2 rock outcrops in the state of Pernambuco. Monthly botanical collections were made from February to September 2015 at Pedra do Cruzeiro (08°09′02.9″ S, 035°45′22.3″ W), municipality of Bezerros and Pico do Papagaio (07°49′25.7″ S, 038°03′14.8″ W), municipality of Triunfo. Fertile specimens were collected following the standard methodology in taxonomy. A total of 58 species were identified from the 2 areas, all widely distributed in Brazil and belonging to 20 b

Abstract:
<b>Background</b> – <i>Amanita</i> is a well-established genus by morphological, biochemical, and molecular data, in which most of the taxa are ectomycorrhizal. The generic characteristics are bilateral lamellar trama (in the agaricoid forms), longitudinally acrophysalidic stipe tissue and schizohymenial development. In the Brazilian semi-arid region putative ectomycorrhizal agaric or chanterelle species are infrequently reported. <i>Amanita lippiae, Cantharellus guyanensis, C. rubescens</i> and <i>Lactarius rupestris</i> were recently described for that region.

During an ornithological inventory conducted in Serra de Maracajú, municipality of Corguinho, we mist-netted and collected an individual of the species. The specimen was prepared as study skin and is held in the ornithological collection of the Museu Nacional, Universidade Federal do Rio de Janeiro, Rio de Janeiro. This record is located 472 km south of the closest visual/song record and 616 km southeast of the closest museum specimen, being

Abstract:
Iguanomorpha (stem + crown Iguania) is a diverse squamate clade with members that predominate many modern American lizard ecosystems. However, the temporal and palaeobiogeographic origins of its constituent crown clades (e.g. Pleurodonta (basilisks, iguanas, and their relatives)) are poorly constrained, mainly due to a meagre Mesozoic-age fossil record. Here, we report on two nearly complete skeletons from the Late Cretaceous (Campanian) of North America that represent a new and relatively large-bodied and possibly herbivorous iguanomorph that inhabited a semi-arid environment.

Abstract:
The 558 km range extension of the Amazonian aroid <em>Dracontium nivosum</em> (Lem.) G.H.Zhu into semi-arid Northeast Brazil is confirmed. This species occurs in Ceará in threatened fragments of <em>brejo</em> forest at ca. 580–870 m elevation. An illustrated taxonomic description is provided. The species' Extent of Occurrence (EOO) is estimated as 356,392 km<sup>2</sup> (meets Least Concern); the Area of Occupancy (AOO), 60 km<sup>2</sup> using a 2×2 km cell (Endangered). Within Ceará the EOO is 41.4 km<sup>2</sup> (Critically Endangered) and the AOO is 16 km<sup>2 </sup>(Endangered).

Abstract:
AbstractTemporal and spatial scarcity of water in semi-arid and seasonal ecosystems often leads to changes in movements and behaviour of large vertebrates, and in the neotropics this dynamic is poorly understood due to logistical and methodological limitations. Here we used camera trapping to elucidate variation in patterns of seasonal use of waterholes and pathways by 10 large-mammal and four large-bird species in the dry forest of north-western Costa Rica. From 2011 to 2015, we deployed trail cameras at 50 locations, including waterholes and three types of pathway (roads, human trails and an

Abstract:
In contrast to their well-studied counterparts in the Neotropics and in Asia, East African montane rain forests are surrounded by semi-arid savanna plains. These plains have a high erosion potential for salt crusts accumulated at the soil surface. Hence it may be hypothesized that East African montane forest ecosystems experience strongly enhanced nutrient inputs via dry deposition, which alters their overall biogeochemistry. The aim of our study was to test this hypothesis by investigating K, Mg, Ca, Na and N-forms in rainfall, throughfall, fine litter, litter percolate and soil solution of a
