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 ...

studies on floristic composition of weeds in an agricultural zone could help to reach a better weed control management strategies. the goal of this article was the study of the floristic composition of lentil weeds grown filds in khorramabad, during 2007-2008. sampling was done on 9 point of each field according to w method in 21farm. in each plat per plate of all weed species were counted sepa...

A floristic survey of the Cactaceae family was carried out in municipality Santa Maria, Brazil, which is localized central region Rio Grande do Sul state. The study conducted between August 2017 and November 2018, during time 14 species were recorded. Five are on endangered list Sul. threatened Echinopsis oxygona (Link) Zucc. Ex. Pfeiff. Otto, Parodia horstii (F. Ritter) N.P. Taylor, glaucina R...

Seasonally dry tropical forest is one of the highly threatened biome. However, studies on the effect of fire on these tree communities are still scarce. In this context, a floristic and structural survey in three forest areas in the southeast of Brazil that were affected by fire between 14 and 25 years ago was performed with the objective of evaluating post-fire regeneration. In each site, five...

This paper presents an operational methodology to map and analyze the floristic richness of “target species” in Natura 2000 sites, making use G.I.S. tools procedures. A Floristic diversity (scale 1:50,000), covering area 612 km2, was produced by a team experts as part management plans “Madonie Mountains” Sites Community Importance (SCIs), located Sicily (Italy). The primary grid represents spec...

In South America, the largest seasonal savanna region is the Brazilian cerrado. Our aim was to study temporal changes in some community descriptors, such as floristic composition, richness, species density, plant density, and cylindrical volume, in a seasonal cerrado, comparing it to a nearby hyperseasonal cerrado. In four different seasons, we placed randomly ten 1 m(2) quadrats in each vegeta...

This paper presents a floristic survey of the wood component of cerrado s.s. (eastern face) and gallery forest (western face) areas carried out in the southern part of the Serra de Maracaju. The dispersal syndromes and floristic relations of this portion of the Serra were compared to those of other formations from different regions of Brazil. Between October 2007 and September 2008, monthly col...
