Orchidaceae of the Grumari restinga: floristic and similarity among restingas in Rio de Janeiro state, Brazil [PDF]

Acta Botanica Brasilica, 2014
Orchidaceae is one of the largest and most diverse plant families in the world. The number of floristic studies of this family in Rio de Janeiro state, Brazil, has increased significantly in recent years. However, only a few such studies have been conducted in areas of restinga vegetation and none of those have examined the similarity, in terms of ...

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 ...

Is the herb-shrub composition of veredas (Brazilian palm swamps) distinguishable?

Acta Botânica Brasílica, 2017
Vereda (Brazilian palm swamp) is a poorly known savannic phytophysiognomy that occurs on moist soils with high herb-shrub floristic richness. This study aimed to document the herb-shrub species of veredas of the Estação Ecológica Serra Geral do Tocantins

Succession stages‐dependent shifts in grassland community stability from asynchrony to population stability mediated by nitrogen enrichment

Ecography, EarlyView.
Understanding the stability dynamics of naturally occurring grassland succession under nutrient enrichment is crucial for effective ecosystem management. We carried out an 11‐year field experiment to examine how grassland community stability responds to nitrogen (N) enrichment across the three successional stages (early‐, mid‐ and late‐successional ...

Moss diatoms show regional structuring, high potential endemism, and an inverse latitudinal diversity gradient in the Arctic

Ecography, EarlyView.
Microorganisms perform essential functions in Arctic terrestrial ecosystems. Yet, their ecology and biogeography are poorly understood, despite being necessary to predict microbial responses to future climate change. Here, we provide the first large‐scale floristic and biogeographic study of the moss diatom flora in the tundra regions of the North ...

Patterns of turnover and floristic similarity show a non-random distribution of naturalized flora in Chile, South America [PDF]

Revista chilena de historia natural, 2008
La distribucion geografica actual de especies exoticas puede ser informativa de los procesos involucrados en las invasiones biologicas facilitadas por humanos. Debido a que los factores ambientales y antropicos pueden afectar la distribucion geografica de plantas exoticas, hipotetizamos que las plantas naturalizadas deberian exhibir una distribucion no

Effect of a Trench Combined With Exclosure on Recovery of Herbaceous Biomass in Degraded Mountain Areas in Hawasa Watershed, Southern Ethiopia

Land Degradation &Development, EarlyView.
ABSTRACT The objective of this study was to evaluate the restoration of herbaceous biomass in degraded mountain lands by comparing the impact of trenches established alongside exclosures (EX‐SWC) to exclosures alone (EX). To achieve the objective, herbaceous biomass was collected from areas restored using EX‐SWC and EX over three consecutive years ...

Carbon Stock and Environmental Variations of Typical Plantations in Mufu Mountain in Hubei Province, China

Land Degradation &Development, EarlyView.
ABSTRACT Forest ecosystems play a critical role in the global carbon cycle. As a significant terrestrial carbon sink, plantations exhibit carbon stock patterns that are shaped by tree species composition, stand structure, and environmental conditions. Here, we investigated typical plantation types in the Mufu Mountain, Hubei Province.
