Threatened Neotropical seasonally dry tropical forest: evidence of biodiversity loss in sap-sucking herbivores over 75 years [PDF]

open access: yesRoyal Society Open Science, 2021
Tropical forests cover 7% of the earth's surface and hold 50% of known terrestrial arthropod species. Alarming insect declines resulting from human activities have recently been documented in temperate and tropical ecosystems worldwide, but reliable data

Tree Species Composition and Forest Stratification along the Gradients in the Dry Deciduous Forests of Godavari Valley, Telangana, India [PDF]

open access: yes, 2018
It is important to understand the tree species composition, abundance, species diversity and stratification in tropical dry deciduous forests that are under threat. A quadrat study was attempted in the dry deciduous forests along the ecological

Spatial variations of nitrogen trace gas emissions from tropical mountain forests in Nyungwe, Rwanda [Discussion paper] [PDF]

open access: yes, 2011
Globally, tropical forest soils represent the second largest source of N2O and NO. However, there is still considerable uncertainty on the spatial variability and soil properties controlling N trace gas emission. To investigate how soil properties affect

Nesting resource availability for cavity adopter birds in a tropical dry forest of Central Mexico

open access: yesRevista Mexicana de Biodiversidad, 2022
Nesting resources for cavity-adopter birds commonly have spatial aggregation patterns within tropical dry forests. Spatial aggregation occurs because large trees, carrying large cavities, are restricted within small semideciduous forest areas.

Asynchronous response of tropical forest leaf phenology to seasonal and el Niño-driven drought. [PDF]

open access: yesPLoS ONE, 2010
The Hawaiian Islands are an ideal location to study the response of tropical forests to climate variability because of their extreme isolation in the middle of the Pacific, which makes them especially sensitive to El Niño-Southern Oscillation (ENSO ...

Forests and Landscapes of Dominican Republic [PDF]

open access: yes, 2015
Aims: This, in conjunction with the diversity of the substrates and the fact that the island is home to the highest mountains in the Caribbean and with a high rate of endemic species, allows them to be differentiated into three major groups –dry forest ...

Canopy Density and Roughness Differentiate Resistance of a Tropical Dry Forest to Major Hurricane Damage

open access: yesRemote Sensing, 2021
Tropical dry forest is vulnerable to increased climate variability with more frequent and severe storms. Studies of hurricane impact on tropical dry forest often focused on individual tree traits. How trees in tropical dry forests work together to combat

Lianas Suppress Seedling Growth and Survival of 14 Tree Species in a Panamanian Tropical Forest [PDF]

open access: yes, 2016
Lianas are a common plant growth form in tropical forests, where they compete intensely with trees, decreasing tree recruitment, growth, and survival. If the detrimental effects of lianas vary significantly with tree species identity, as is often assumed,
