Understanding the maintenance of high tropical tree species diversity requires disentangling the effects of habitat vs. geographic distance. Using floristic, topographic, and soil nutrient data from 105 0.6-ha plots in mixed dipterocarp forest throughout Sarawak, Malaysian Borneo, we explore the degree to which floristic patterns are habitat-driven from local to landscape scales. We assess how ...

ABSTRACT The northeastern slope of the Andes is an area high diversity ferns and lycophytes. In this study we assessed patterns lycophytes in ten 250 m x 2 plots installed at three elevational zones, from 418 to 3447 m.a.s.l., Napo province Ecuador. Floristic was measured using Hill numbers by partitioning species diversity. Three functional indices were calculated a set five leaf traits weight...

The Atlantic Forest contains more bryophyte species and greater endemism than any other Brazilian phytogeographic domain. We analyzed the bryoflora of an remnant along southern coast to examine: (i) floristic composition, richness, life forms bryocenological groups in different phytophysiognomies (humid lowlands, sandy Restinga forests, swampy forests); (ii) similarities among them; and, (iii) ...

BACKGROUND AND AIMS A central goal of biogeography and ecology is to uncover and understand distributional patterns of organisms. China has long been a focus of attention because of its rich biota, especially with respect to plants. Using 290 floras from across China, this paper quantitatively characterizes the composition of floristic elements at multiple scales (i.e. national, provincial and ...

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...

The aim was to assess patterns of plant diversity in response to elevation and disturbance in a tropical mountain. The study area was located in north-central portion of the Eastern Cordillera of the Ecuadorian Andes, on a road from 1,150 m a.s.l. (Osayacu) to 4,000 (Papallacta). Along a mountain road spanning a wide altitudinal gradient, at 20 elevations we sampled three plots: one at the road...
