Ecosystem Dynamics of a Subtropical Floodplain Forest
Ecological Monographs, 1985The carbon, phosphorus, and water cycles of a subtropical floodplain forest, and related ecosystem characteristics, were studied. Located at 750 m elevation in Puerto Rico (latitude 18°N) the forest had 27 tree species, 3059 stems/ha, a basal area of 42.4 m2/ha, maximum height of 17 m, and a leaf area index of 3.3. Palm (Prestoea montana) dominated the

Proximate cues of flowering in a subtropical rain forest
Biotropica, 2023AbstractPlants have evolved mechanisms to track seasonal variation in environmental resources, enabling them to time key life‐history events to appropriate seasons. While the proximate cues for flowering initiation are well documented in the temperate region, it is still unclear what the flowering cues are in the tropics, especially in the subtropics ...

Nitrogen sink in a small forested watershed of subtropical China
Journal of Environmental Sciences, 2011Global nitrogen (N) emission and deposition have been increased rapidly due to massive mobilization of N which may have long-reaching impacts on ecosystems. Many agricultural and forest ecosystems have been identified as secondary N sources. In the present study, the input-output budget of inorganic N in a small forested watershed of subtropical China ...

Threshold and multiple indicators for nitrogen saturation in subtropical forests
Environmental Pollution, 2018The influence of nitrogen (N) deposition on forest ecosystems largely depend on the N status. Developing threshold and practical indicators for N saturation in subtropical forests, with extremely high N deposition, would both enhance forest management and the assessments of global N balance and carbon (C) sequestration.

Soil Acidification in Response to Acid Deposition in Three Subtropical Forests of Subtropical China
Pedosphere, 2010Abstract Long-term changes in soil pH, the current status of soil acidification, and the response of bulk soil and soil water pH to experimental nitrogen addition under three subtropical forests were investigated in Dinghushan Biosphere Reserve of subtropical China.

Partitioning beta diversity in a subtropical broad‐leaved forest of China
Ecology, 2009The classical environmental control model assumes that species distribution is determined by the spatial variation of underlying habitat conditions. This niche‐based model has recently been challenged by the neutral theory of biodiversity which assumes that ecological drift is a key process regulating species coexistence.

Avian Extinctions from Tropical and Subtropical Forests
Annual Review of Ecology, Evolution, and Systematics, 2004▪ Abstract Tropical forests are being lost at an alarming rate. Studies from various tropical locations report losses of forest birds as possibly direct or indirect results of deforestation. Although it may take a century for all the sensitive species to be extirpated from a site following habitat loss, species with larger or heavier bodies and those ...

Assemblage of forest communities in subtropical montane forests of western Mexico
Journal of Tropical EcologyAbstract Functional diversity indices have been used to differentiate the relative contribution of stochastic and deterministic processes that modulate the assemblage of communities; however, knowledge regarding the relative contribution of assemblage mechanisms in forest communities is scarce.

Energy fluxes at a subtropical mountain cloud forest
Forest Ecology and Management, 2006Abstract Results are presented of a 5-day micrometeorological experiment to study the fluxes of radiation and sensible and latent heat above a homogeneous Chamaecyparis forest in northeastern Taiwan at 1650 m a.s.l. The site exhibits a well pronounced diurnal cycle of winds, with valley winds from the SE during daytime, advecting warm and moist air

Geomorphological impacts of a tornado disturbance in a subtropical forest
CATENA, 2015article i nfo We studied tree uprooting associated with an EF2 tornado that touched down in portions of the Ouachita Moun- tains in western Arkansas in 2009. In the severe blowdown areas all trees in the mixed shortleaf pine-hardwood forest were uprooted or broken, with no relationship between tree species or size and whether uprooting or breakage ...
