WETLAND CLASSIFICATION FOR BLACK DUCK HABITAT MANAGEMENT USING COMBINED POLARIMETRIC RADARSAT 2 AND SPOT IMAGERY
Wetlands Synthetic Aperture Radar Polarimetric data Decomposition Classification
2018/5/16
The black duck population has decreased significantly due to loss of its breeding habitat. Wetlands are an important feature that relates to habitat management and requires monitoring. Synthetic Apert...
Open and closed seascapes: Where does habitat patchiness create populations with high fractions of self-recruitment?
coral reef seascapes dispersal
2015/12/11
Which populations are replenished primarily by immigrants (open) and which
by local production (closed) remains an important question for management with implications
for response to exploitation, p...
Many corals host thermally resistant symbionts in high-temperature habitat
Symbiodinium Host–symbiont specifi city
2015/12/11
Physiologically distinct lines of dinoflagellate
symbionts, Symbiodinium spp., may confer distinct thermal
tolerance thresholds on their host corals. Therefore, if a
coral can alternately hos...
Whole-Genome Positive Selection and Habitat-Driven Evolution in a Shallow and a Deep-Sea Urchin
positive selection dN/dS
2015/12/11
Comparisons of genomic sequence between divergent species can provide insight into the action of natural
selection across many distinct classes of proteins. Here, we examine the extent of positive se...
Modeling the spread of the Argentine ant into natural areas: Habitat suitability and spread from neighboring sites
Invasion model Grid-based model
2015/12/10
To predict a fine-scale invasion of Argentine ants (Linepithema humile) into a natural area from the surrounding suburban matrix, we introduce a grid-based invasion model, similar to a cellular ...
Blue Whale Habitat Associations in the Northwest Pacific:Analysis of Remotely-Sensed Data Using a Geographic Information System
Blue Whale Habitat Associations Northwest Pacific Remotely-Sensed Data Geographic Information System
2015/8/3
Detection of stereotypic call sequences are now commonly used to locate blue whales (Balaenoptera musculus) in the North Pacific (e.g., Watkins et al., 2000a; Stafford et al., 1998; 2001; McDonald et ...
andscape Estimates of Habitat Types, Plant Biomass, and Invertebrate Densities in a Georgia Salt Marsh
Habitat Types Plant Biomass Invertebrate Densities
2015/7/16
Salt marshes often contain remarkable spatial heterogeneity at multiple scales across the landscape. A combination of advanced remote-sensing approaches (hyperspectral imagery and lidar) and conventio...
A Habitat Suitability Model for Ricord’s Iguana in the Dominican Republic

2015/1/9
The West Indian iguanas of the genus Cyclura are the most endangered group of lizards in the world (Burton & Bloxam, 2002). The Ricord’s iguana, Cyclura ricordii, is listed as critically endangered by...
Habitat Use and Seasonal Movement Patterns of Four-toed Salamanders (Hemidactylium scutatum) in Massachusetts
habitat use movement CART model
2015/1/4
Understanding the movement phenology of the four-toed salamander (Hemidactylium scutatum) is essential to guide management practices. I examined the relationship between environmental variables and th...
Dynamical behavior of a plant-herbivore system with nutrient cycling in a polluted habitat
Plant Herbivore Pollutant
2010/9/21
In this paper, a mathematical model is proposed to study the effect of pollutant on the existence of plant-herbivore system with nutrient cycling. The deterministic mathematical model is formulated us...
The role of asymmetric interactions on the effect of habitat destruction in mutualistic networks
asymmetric interactions effect habitat destruction mutualistic networks
2010/11/15
Plant-pollinator mutualistic networks are asymmetric in their interactions: specialist plants are pollinated by generalist animals, while generalist plants are pollinated by a broad involving speciali...
Metagenomic potential of microbial assemblages in the surface waters of the central Pacific Ocean tracks variability in oceanic habitat
Metagenomic potential microbial assemblages the surface waters the central Pacific Ocean tracks variability oceanic habitat
2014/4/17
Oceanic habitats may select for different organisms, thereby tuning genomic capabilities to local environmental conditions. To understand the relationship between microbial assemblage composition, fun...
