Habitat differentiation among tree species with small-scale variation of humus depth and topography in a tropical heath forest of Central Kalimantan, Indonesia
TLDR
In this article, small-scale spatial association of the distribution for 55 abundant tree species with two environmental factors (humus depth and surface microtopography) was examined in two 1-ha plots of a heath (kerangas) forest in Central Kalimantan, Indonesia.Abstract:
Small-scale spatial association of the distribution for 55 abundant tree species with two environmental factors (humus depth and surface microtopography) was examined in two 1-ha plots of a heath (kerangas) forest in Central Kalimantan, Indonesia. More than 80% of the 55 species showed a significant habitat preference in humus depth and/or relative elevation in at least one plot. In particular, ten species occurring in both plots showed a consistent significant preference for humus depth or relative elevation in the two plots. Using randomization tests, however, only five species significantly associated with humus depth and no species with relative elevation. These results suggest that edaphic and topographic factors, especially humus depth, contribute to determining local spatial distribution and floristic composition of abundant tree species in the forest.read more

The Tropical Rain Forest: An Ecological Study
Jiro Kikkawa,Len Webb +1 more
TL;DR: This long-awaited book would seem to mark the end of classical tropical botany and phytogeography as subjects for scholarly pursuits, but it may well become "a record of what the rainforest was like in the twentieth century", as stated on its first page.

Mesoscale distribution patterns of Amazonian understorey herbs in relation to topography, soil and watersheds
TL;DR: The results indicate high turnover in species composition, on spatial scales of 5‐10 km in central Amazonia, which is not necessarily associated with soil change, and knowledge of geographical, historical or other landscape features, such as watershed morphology, may therefore be necessary to predict the turnover patterns over mesoscales.

TL;DR: It is found that topography is an important factor for local vascular plant diversity patterns in a broad range of habitats throughout the world, even in relatively lowlands, however, the mechanisms involved are varied and complex.

TL;DR: In this paper, a GIS-environmental database with 5 arc minute (c. 10 × 10 km) resolution was combined with tree inventory data to identify environmental correlates for tropical tree diversity and composition.

TL;DR: In this article, the authors used tree and soil data from 48 and 32 1ha plots, respectively, in a Bolivian moist and dry forest, to evaluate the relationship between soil characteristics and forest structure and diversity in each of the two forest types.

Herbivores and the Number of Tree Species in Tropical Forests
TL;DR: Any event that increases the efficiency of the predators at eating seeds and seedlings of a given tree species may lead to a reduction in population density of the adults of that species and/or to increased distance between new adults and their parents.

Spatial Autocorrelation: Trouble or New Paradigm?
TL;DR: The paper discusses first how autocorrelation in ecological variables can be described and measured, and ways are presented of explicitly introducing spatial structures into ecological models, and two approaches are proposed.

Gridding with continuous curvature splines in tension
Walter H. F. Smith,Paul Wessel +1 more
TL;DR: In this article, the authors proposed to add tension to the elastic-plate flexure equation to improve the convergence of a minimum curvature gridding algorithm with a tension parameter, where the same system of equations must be solved in either case and only the relative weights of the coefficients change.

Tropical rainforest gaps and tree species diversity
TL;DR: Interest in the role of adaptations by species to different regeneration sites in structuring plant assemblages in general and tropical tree communities in particular is heightened by rising rates of deforestation throughout the tropics and a critical need for management strategies of the remaining preserves.
