Question: Cocos nucifera, the coconut palm, has a pantropical distribution and reaches near monodominance in many atolls, low lying islands and coastal regions. This paper examines the ecological correlation between C. nucifera abundance and changes in forest structure, floristic diversity and forest soil characteristics. Location: Palmyra Atoll NWR (USA), Central Pacific Ocean. Methods: Plant ...

The genetic and evolutionary relationships among floral nectar-dwelling Pseudomonas 'sensu stricto' isolates associated to South African and Mediterranean plants were investigated by multilocus sequence analysis (MLSA) of four core housekeeping genes (rrs, gyrB, rpoB and rpoD). A total of 35 different sequence types were found for the 38 nectar bacterial isolates characterised. Phylogenetic ana...

The Atlantic forest is a terrestrial biome that extends along the Brazilian coast and has been subject of intense deforestation for decades. There are presently several efforts to try to preserve the flora and fauna of what remains from this region (e.g., Coco et al. 2014, Maciel-Silva et al. 2014, Missagia et al. 2014), but several questions on how the distinct floristic units of this biome ar...

flora of jahanbin mountain area in chaharmahal and bakhtiari province, located between shahrekord and hafshejan cities, with 12’187 hectares and 2’150 to 3’300 m elevation above sea level, is investigated. vegetation of this area comprises of 273 species, 189 genera and 42 families. asteraceae (37 species, 13.5%), poaceae (31 species, 11.3%) and fabaceae (25 species, 9.1%) were the most importa...

the mountainous area of fereizi is located in northwestern binalood range, khorassan, north east of iran. special climatic and geographical characteristics of the area make it a suitable habitat for various plant species. as a part of a research poject on the flora and vegetation of binalood mountain range, the floristic composition of this area, life forms and chorology of vascular plants have...

This study describes the foraging ecology of birds during summer and winter in two different types of coffee agroecosystems in Chiapas, Mexico. Avian foraging behavior is documented in two agroecosystems of differing management intensity, structurally similar but with different levels of floristic diversity, during summer and winter seasons. The distribution of tree species used by birds was mo...

The monitoring of ecosystems alterations has become a crucial task in order to develop valuable habitats for rare and threatened species. The information extracted from hyperspectral remote sensing data enables the generation of highly spatially resolved analyses of such species’ habitats. In our study we combine information from a species ordination with hyperspectral reflectance signatures to...

Despite the diversity of Burkholderia species known to nodulate legumes in introduced and native regions, relatively few taxa have been formally described. For example, the Cape Floristic Region of South Africa is thought to represent one of the major centres of diversity for the rhizobial members of Burkholderia, yet only five species have been described from legumes occurring in this region a...
