Competition explains tropical tree species coexistence and abundance

, 2023
Abstract The numerous tree species co-occurring in tropical forests presents a challenging puzzle1. Conventional competition models suggest that such coexistence is improbable2–7, but this study offers a novel solution. By modelling interspecific competition as both competitive intensity and susceptibility, we provide conditions for stable ...

Patterns of understorey bird diversity across Amazonian forests: survey effort and range maps predict local species richness

Ecography, EarlyView.
Species diversity typically increases from higher to lower latitudes, but the regional‐scale variation along this geographic gradient remains unclear. It has been suggested that species diversity throughout Amazonia generally increases westward toward the Andes, but this pattern and its environmental determinants require further investigation for most ...

Specific and generic stem biomass and volume models of tree species in a West African tropical semi-deciduous forest

Silva Fennica, 2016
The quantification of the contribution of tropical forests to global carbon stocks and climate change mitigation requires availability of data and tools such as allometric equations.

Trends in marine species distribution models: a review of methodological advances and future challenges

Ecography, EarlyView.
Correlative species distribution models (SDMs) are quantitative tools in biogeography and macroecology. Building upon the ecological niche concept, they correlate environmental covariates to species presence to model habitat suitability and predict species distributions.

Effects of Lightning on Trees: A Predictive Model Based on in situ Electrical Resistivity [PDF]

, 2017
The effects of lightning on trees range from catastrophic death to the absence of observable damage. Such differences may be predictable among tree species, and more generally among plant life history strategies and growth forms.

Freshwater fish functional diversity shows diverse responses to human activities, but consistently declines in the tropics

Ecography, EarlyView.
Freshwater environments are intertwined with human activities and the consequence has been environmental degradation and biodiversity loss. Fish provide key ecological and economic benefits, and fish abundance and diversity can be affected by human activities resulting in functional diversity (FD) changes that might scale up to ecosystem impacts ...

Elevational Distribution of Adult Trees and Seedlings in a Tropical Montane Transect, Southwest China

Mountain Research and Development, 2016
Montane habitats are characterized by high variation of environmental factors within small geographic ranges, which offers opportunities to explore how forest assemblages respond to changes in environmental conditions.

The scaling of seed‐dispersal specialization in interaction networks across levels of organization

Ecography, EarlyView.
Natural ecosystems are characterized by a specialization pattern where few species are common while many others are rare. In ecological networks involving biotic interactions, specialization operates as a continuum at individual, species, and community levels. Theory predicts that ecological and evolutionary factors can primarily explain specialization.

Tree community variation in a tropical continental island according to slope aspect and human interference

Anais da Academia Brasileira de Ciências, 2018
Associating description of unrecorded tropical tree community structure to sampling approaches that can help determine mechanisms behind floristic variation is important to further the comprehension of how plant species coexist at tropical forests. Thus,
