Habitat classification Phragmites australis reedbed structural heterogeneity vegetation complexity wetland conservation
2023/12/19
Mapping 3D vegetation structure in wetlands is important for conservation and monitoring. Openly accessible country-wide Airborne Laser Scanning (ALS) data-using light detection and ranging (lidar) te...
MODELLING FINE SCALE MOVEMENT CORRIDORS FOR THE TRICARINATE HILL TURTLE
Habitat connectivity Fine Scale Tricarinate Hill-turtle Circuit theory Geographical Information Systems India

Habitat loss and the destruction of habitat connectivity can lead to species extinction by isolation of population. Identifying important habitat corridors to enhance habitat connectivity is imperativ...
Micro- to Fine-Scale Chemical Gradients and Layers in Stratified Coastal Waters
Stratified Coastal Waters Chemical Gradients and Layers
2015/8/6
Models of biogeochemical dynamics and chemical variability in coastal waters have traditionally relied on the assumption that small-scale mixing processes are sufficiently strong and isotropic to rapi...
Fine-scale genetic structure and dispersal distance in the harvester ant Pogonomyrmex barbatus
dispersal distance Fine-scale genetic structure
2015/12/10
Dispersal has important genetic and evolutionary consequences. It is notoriously difficult to study in some ant
species, because reproductives fly from parent nests to
mating aggregation...

The proper knowledge of spatial precipitation structure is important as much as that of microphysics processes for reliable quantitative precipitation forecasts. This study considers some aspects of h...
Chemistry of surface waters: Distinguishing fine-scale differences in sea grass habitats of Chesapeake Bay
Chemistry of surface waters Distinguishing fine-scale differences sea grass habitats Chesapeake Bay
2014/5/9
We tested the hypothesis that the physical and chemical processes acting in sea grass habitats of the lower Chesapeake Bay are spatially structured and that dissolved elemental chemistry of sea grass-...
From Meters to Kilometers: A Look at Ocean-Color Scales of Variability, Spatial Coherence, and the Need for Fine-Scale Remote Sensing in Coastal Ocean Optics
Process of chemistry optics micrometers non-biological water nutrients and phytoplankton clastic sediment
2015/7/29
The physical, biological, chemical, and optical processes of the ocean operate on a wide variety of spatial and temporal scales, from seconds to decades and from micrometers to thousands of kilometers...
