Explosive Radiation of Malpighiales Supports a Mid-Cretaceous Origin of Modern Tropical Rain Forests [PDF]

open access: yes, 2005
Fossil data have been interpreted as indicating that Late Cretaceous tropical forests were open and dry adapted and that modern closed-canopy rain forest did not originate until after the Cretaceous-Tertiary (K/T) boundary.

GPS and GIS Methods in an African Rain Forest: Applications to Tropical Ecology and Conservation

open access: yesEcology and Society, 2002
Since the completion of the Navstar Global Positioning System (GPS) in 1995, the integration of GPS and Geographical Information Systems (GIS) technology has expanded to a great number of ecological and conservation applications.

(5d RG-flow) trees in the tropical rain forest

open access: yesJournal of High Energy Physics, 2021
5d superconformal field theories (SCFTs) can be obtained from 6d SCFTs by circle compactification and mass deformation. Successive decoupling of hypermultiplet matter and RG-flow generates a decoupling tree of descendant 5d SCFTs.

Simulating anthropogenic impacts to bird communities in tropical rain forests [PDF]

open access: yes, 2002
We used an aggregated modelling approach to simulate the impacts ofanthropogenic disturbances on the long-term dynamics of faunal diversityin tropical rain forests. We restricted our study to bird communities eventhough the approach is more general.

The effect of charcoal production on carbon cycling in African biomes

open access: yesGCB Bioenergy, 2023
Using biomass for charcoal production in sub‐Saharan Africa (SSA) may change carbon stock dynamics and lead to irreversible changes in the carbon balance, yet we have little understanding of whether these dynamics vary by biome in this region. Currently,

Successional, spatial, and seasonal changes in seed rain in the Atlantic forest of southern Bahia, Brazil.

open access: yesPLoS ONE, 2019
Seed arrival is a limiting factor for the regeneration of diverse tropical forests and may be an important mechanism that drives patterns of tree species' distribution.

Community structure and environmental determinants of the bacterial and fungal gut microflora in Hainan gibbons (Nomascus hainanus)

open access: yesGlobal Ecology and Conservation, 2022
High-throughput sequencing technology was used to establish the OTU (Operational Taxonomic Units) composition and diversity of bacteria and fungi in the gut of three family groups of Hainan gibbons (Nomascus hainanus) in the Bawangling National Nature ...

Temporal variation in abundance and diversity of butterflies in Bornean rain forests: opposite impacts of logging recorded in different seasons [PDF]

open access: yes, 2005
We used traps baited with fruit to examine how the temporal variation of butterflies within primary forest in Sabah, Borneo differed between species. In addition, we compared patterns of temporal variation in primary and selectively logged forest, and we

Searching for signatures across microbial communities: Metagenomic analysis of soil samples from mangrove and other ecosystems

open access: yesScientific Reports, 2017
In this study, we categorize the microbial community in mangrove sediment samples from four different locations within a vast mangrove system in Kerala, India.

Seasonal variation in soil and plant water potentials in a Bolivian tropical moist and dry forest [PDF]

open access: yes, 2010
We determined seasonal variation in soil matric potentials (¿soil) along a topographical gradient and with soil depth in a Bolivian tropical dry (1160 mm y-1 rain) and moist forest (1580 mm y-1).
