REQUERIMENTOS ECOLÓGICOS DE ESPÉCIES COM POTENCIAL PAISAGÍSTICO DA RESTINGA DE MARACANÃ, PARÁ
O potencial paisagístico pode ser atribuído a todo vegetal que apresente um uso ornamental e de maneira geral, qualquer vegetal poderá ter essa finalidade. Este trabalho teve como objetivo identificar alguns requerimentos ecológicos de espécies vegetais com potencial paisagístico da restinga da Área de Proteção Ambiental, Algodoal-Maiandeua, Maracanã, Pará, Brasil. Foram investigadas oito espécies entre árvores, palmeiras e arbustos. Observou-se que as características dominantes foram: propagação sexuada por sementes, luminosidade média e plantio indicado no ambiente externo. As espécies apresentam potencial para arborização urbana e jardins. Novas pesquisas poderão auxiliar no cultivo e na comercialização

MAMMALS IN PORTUGAL : A data set of terrestrial, volant, and marine mammal occurrences in P ortugal
Mammals are threatened worldwide, with 26% of all species being includedin the IUCN threatened categories. This overall pattern is primarily associatedwith habitat loss or degradation, and human persecution for terrestrial mam-mals, and pollution, open net fishing, climate change, and prey depletion formarine mammals. Mammals play a key role in maintaining ecosystems func-tionality and resilience, and therefore information on their distribution is cru-cial to delineate and support conservation actions. MAMMALS INPORTUGAL is a publicly available data set compiling unpublishedgeoreferenced occurrence records of 92 terrestrial, volant, and marine mam-mals in mainland Portugal and archipelagos of the Azores and Madeira thatincludes 105,026 data entries between 1873 and 2021 (72% of the data occur-ring in 2000 and 2021). The methods used to collect the data were: live obser-vations/captures (43%), sign surveys (35%), camera trapping (16%),bioacoustics surveys (4%) and radiotracking, and inquiries that represent lessthan 1% of the records. The data set includes 13 types of records: (1) burrowsjsoil moundsjtunnel, (2) capture, (3) colony, (4) dead animaljhairjskullsjjaws, (5) genetic confirmation, (6) inquiries, (7) observation of live animal (8),observation in shelters, (9) photo trappingjvideo, (10) predators dietjpelletsjpine cones/nuts, (11) scatjtrackjditch, (12) telemetry and (13) vocalizationjecholocation. The spatial uncertainty of most records ranges between 0 and100 m (76%). Rodentia (n=31,573) has the highest number of records followedby Chiroptera (n=18,857), Carnivora (n=18,594), Lagomorpha (n=17,496),Cetartiodactyla (n=11,568) and Eulipotyphla (n=7008). The data setincludes records of species classified by the IUCN as threatened(e.g.,Oryctolagus cuniculus[n=12,159],Monachus monachus[n=1,512],andLynx pardinus[n=197]). We believe that this data set may stimulate thepublication of other European countries data sets that would certainly contrib-ute to ecology and conservation-related research, and therefore assisting onthe development of more accurate and tailored conservation managementstrategies for each species.

Mammals in Portugal: a data set of terrestrial, volant, and marine mammal occurrences in Portugal

FORMATIONS OF COASTAL FORESTS IN THE AMAZON AND ECOLOGICAL RELATIONS WITH VASCULAR EPIPHYTES
<div><p>ABSTRACT Was investigated the vascular epiphytes and relate it to the composition and structure of the arboreal component in two formations of coastal forests in the Algodoal-Maiandeua Environmental Protetion Area, Maracanã, Pará, Brazil. We demarcated four 50m x 50m parcels (two in a dry forest and two in a flooding forest). Were registered and identified all the vascular epiphytes as well as their phorophytes. The abundance and richness of epiphytes were evaluated by the epiphyte/phorophyte ratio and differences in the use of phorophytic species by epiphytes were verified using a MDS. To analyze the influence of phorophyte diameter and height we used a multiple regression. In the dry forest we registered 193 arboreal individuals, of which 96 were phorophytes. Anacardium occidentale was the most abundant arboreal and phorophyte species as well. In the flooding forest we registered 234 arboreal individuals, 131 phorophytes. The most abundant arboreal species were also the ones with the greater number of phorophytes. In both forests the phorophytes were occupied in different ways by the epiphytes. No significant relation was found between phorophyte diameter and height and epiphytes abundance in the dry forest, nevertheless, there was a significant relation in the flooding forest.</p></div
Climate change effects on marginal savannas from central-north Brazil
Abstract This study estimated the potential effects of climate change on peripheral plant diversity by predicting the distribution of species from Cerrado of Northern Brazil. Ecological niche modeling was used to provide present and future projections of responses in terms of occurrence of ten woody species based on four algorithms and four future climate change scenarios for the year 2050. Potential refuge areas for conservation actions were identified, and evidence of the vulnerability of the flora was demonstrated based on the disparity between potential areas of climate stability amid current protected areas. The results suggested a lack of pattern between the scenarios and an idiosyncratic response of the species, indicating different impacts on plant communities and the existence of unequal stable alternative conditions, which could bring consequences to the ecological relationships and functionality of the floras. Even in the most pessimistic scenarios, most species presented an expansion of potential occurrence areas, suppressing or cohabiting with species of adjacent biomes. Typically marginal plants were the most sensitive. Overlapping adequate habitats are concentrated in the NBC. The analysis of habitats in relation to anthropized areas and PAs demonstrate low future effectiveness in the protection of these savannas
