Article
Full-text available
Bamboos are prominent components of many tropical ecosystems, yet little is known about the physiological mechanisms utilized by these gigantic forest grasses. Here, we present data on the water transport properties of Chusquea ramosissima and Merostachys claussenii, monocarpic bamboo grasses native to the subtropical Atlantic forests of Argentina....
Article
Full-text available
The bamboo fire cycle hypothesis proposed by Keeley and Bond (1999) argues that lightning-ignited wildfire has synchronized flowering and recruitment of bamboos throughout Asia. They argue that mast flowering followed by mass mortality leads to fuel-load accumulation, encouraging ignition by lightning strikes that results in complete consumption of...
Article
Full-text available
Variability in the size distributions of populations is usually studied in monocultures or in mixed plantings of two species. Variability of size distributions of populations in more complex communities has been neglected. The effects of seeding density (35 or 350 seeds/species/m2) and presence of small vertebrates on the variability of size distri...

Patterns in soil moisture availability affect plant survival, growth and fecundity. Here we link patterns in soil moisture to physiological and demographic consequences in Florida scrub plants. We use data on different temporal scales to (1) determine critical soil moisture content that leads to loss of turgor in leaves during predawn measurements...
Article
Full-text available
The phenology of sprouts (>1 year old, up to 1.5 m in height) and seedlings (x), leaf relative water content (RWC; % turgid weight), and xylem specific conductivity (K S; kg s–1 m–1 MPa–1) of sprouts were measured on two occasions during the dry season. In addition, K S of seedlings (x of deciduous species was significantly higher at the second s...

This study presents data on woody plant species richness and diversity of an inaccessible dry forest of Tula Mountains Woodland (TMW) located in the northeast of Nigeria. TMW supports a minimally disturbed mosaic of dry forest‐woodland. We sampled woody species in 190 plots of size 0.01‐ha, spaced 50 m apart on series of line transects. We found a...

Invasive alien species (IAS) and land-use represent major threats to native plant communities around the globe. However, studies on IAS and potential ecological impacts in the context of land-use are limited in sub-Saharan Africa. Using a set of 45 plots in Jos metropolis in central Nigeria, we assessed the abundance of invasive Tithonia diversifol...

Biological invasion has been identified as one of the major threats to biodiversity and ecosystem function. However, studies on introduced plant species and their potential ecological impact on natives are limited in Nigeria. We investigated the species composition of native and introduced plant across land-use types in Jos metropolis, central Nige...
Article
Full-text available
Bamboos are a diverse and ecologically important group of plants that have the potential to modulate the structure, composition, and function of forests. With the aim of increasing the visibility and representation of bamboo in forest surveys, and to standardize techniques across ecosystems, we present a protocol for bamboo monitoring in permanent...
Article
en Protected areas such as forest reserves are often assumed to be best ways to conserve biodiversity and maintain intact ecosystems. We examined woody plant composition and diversity in the gallery forest and savannah woodland habitats of Amurum Forest Reserve and areas immediately surrounding it in Jos, Nigeria. A total of 100 10 × 10 m sample pl...
Article
Full-text available
This paper describes a stream biomonitoring program that builds capacity in undergraduate college students in the field of freshwater ecology and conservation. The program involves sampling of aquatic macroinvertebrates and hydrological parameters in streams of the state of Meghalaya, India. Several colleges from Shillong initiated short-term, one-...
Article
Full-text available
Ecosystem management practices that modify the major drivers and stressors of an ecosystem often lead to changes in plant community composition. This paper examines how closely the trajectory of vegetation change in seasonally-flooded wetlands tracks management-induced alterations in hydrology and soil characteristics. We used trajectory analysis,...
Article
Full-text available
Coastal ecosystems lie at the forefront of sea level rise. We posit that before the onset of actual inundation, sea level rise will influence the species composition of coastal hardwood hammocks and buttonwood (Conocarpus erectus L.) forests of the Everglades National Park based on tolerance to drought and salinity. Precipitation is the major water...

Full-text available
We investigate the effects of Hurricane Wilma’s storm surge (23–24 October 2005) on the dominant tree Pinus elliottii var densa (South Florida slash pine) and rare plant species in subtropical pine rocklands of the Lower Florida Keys. We examine the role of elevation on species abundance in 1995 (Hurricane Betsy in 1965), 2005 (Hurricane Georges in...

Background/Question/Methods In this study we examine leaf traits of 11 woody shrubs and eight herbaceous species in Florida scrub ecosystem. Aims of our study are to test if the patterns of correlation between leaf traits such as leaf longevity, Specific Leaf Mass (SLM), and photosynthetic capacity are parallel to the global leaf traits relations...
Article
Full-text available
Although belowground biomass patterns are important in understanding aboveground re-sponses, few studies have quantified how belowground biomass changes in response to fire cycles. In this study, we determined if patterns of time-since-fire (TSF; range 3 yr to 25 yr) affect belowground and aboveground biomass in scrubby flatwoods, a type of Flor-id...
Article
Full-text available
The variation in morphological traits and photosynthetic potentials associated with light conditions in the canopy can determine whole-plant function. However, leaf structure-function relationships are poorly studied in ecosystems experiencing nominal light attenuation. We examined morphological leaf traits (area, specific leaf area, thickness, rev...
Article
Full-text available
Florida scrub is a pyrogenic shrubland ecosystem occurring on well-drained sands derived from contemporary and relictual beach dunes. Despite average annual precipitation > 1300 mm, Florida scrub is dominated by xeromorphic plants. We monitored spatio-temporal variation in soil moisture to determine if the distribution of Florida scrub communities...

"Fire is an integral component of many temperate and tropical ecosystems, but it can be disruptive when it occurs in normally fire-free environments. Tropical deciduous forests in India have experienced annual anthropogenic fires for hundreds of years. We examined the effects of anthropogenic fires and fire exclusion on the stature of juvenile tree...
Article
Full-text available
A century of annual burning of the understory of otherwise fire-free decid-uous tropical forest in central India has favored seven tree species that produce sprouts or suckers from root buds (root-sprouters) over 37 species that produce sprouts basally from root crowns (root-crown resprouters). Experiments over two years demonstrated that low-inten...

Full-text available
The regressive succession model hypothesizes tropical savanna-woodlands to be a degraded stage of primary deciduous forests. Species diversity, richness and evenness of woody species in savanna-woodlands, secondary deciduous forests and mature deciduous forests of central India were compared to test if the regressive succession explained pattern in...
Article
Components of anthropogenic fire regime are described in a central Indian deciduous forest managed by the Gond tribals of Mendha in Gadchirolli District of Maharashtra. Characteristics such as fire intensity, flame height and fire residence time were used to describe the anthropogenic fire regime. The study was conducted over three consecutive year...

Vegetation structure and composition of abandoned Tectona grandis (teak) plantations was compared with the neighboring dry deciduous secondary forests in Satpura Conservation Area located in central India. Species diversity and stem density were compared between plantations and secondary dry deciduous forests separately for adults and seedlings of...

To measure evapotranspiration from a variety of graminoid, shrub and wetland plant species by growing them in water-level and weighing lysimeters in subtropical southcentral Florida, and by measuring water loss from these. The data can fill a gap in ET estimates from subtropical savanna and wetland ecosystems, and can also be used to calibrate ET models for the region.
