Habitat Fragmentation

2020
Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition. Perforation and dissection often occur during the initial stages of...

Biofilms have complex interactions with their surrounding environment. To comprehensively investigate biofilm-environment interactions, we present here a series of methods to create heterogeneous chemical environment for biofilm development, to quantify local flow velocity, and to analyze mass transport in and around biofilm colonies.

We demonstrate the utility of remotely sensed data and the newly developed Software for Assisted Habitat Modeling (SAHM) in predicting invasive species occurrence on the landscape. An ensemble of predictive models produced highly accurate maps of tamarisk (Tamarix spp.) invasion in Southeastern Colorado, USA when assessed with subsequent field validations.

Source: Laboratory of Dr. Neal Abrams — SUNY College of Environmental Science and Forestry Transition metals are found everywhere from vitamin supplements to electroplating baths. Transition metals also make up the pigments in many paints and compose all minerals. Typically, transition metals are found in the cationic form since they readily oxidize, or lose electrons, and are surrounded by electron donors called ligands. These ligands do not form ionic or covalent bonds with the metal center,...
FAQs
Useful features include vegetation layers, substrate types, shelters, gaps, and the three-dimensional arrangement of structural elements. Examining these components together shows how physical variation creates or limits spaces and resources within a habitat. This broader structural perspective can help explain differences in species abundance, distribution, movement, and resource use more effectively than a single feature alone.
Three-dimensional arrangement captures how habitat features are positioned through space rather than simply recording whether they are present. Differences in layering, gaps, and shelter can change the physical opportunities available to organisms and influence how they move or use resources. Recording spatial structure therefore strengthens interpretation of relationships between environmental conditions and ecological communities.
Comparing structural measurements across locations or time periods can show whether disturbance or environmental change has altered vegetation layers, substrates, shelter, gaps, or spatial arrangement. Those changes provide a physical basis for interpreting shifts in species abundance, distribution, movement, or resource use. The assessment therefore connects observable habitat modification with broader changes in ecological communities.
Researchers can combine standardized field observations with direct measurements, mapping, or image-based analysis. Field approaches document structural features in a consistent manner, while maps and images help represent their spatial distribution and arrangement. Using more than one approach can provide complementary information for habitat comparison, biodiversity monitoring, and evaluating structural changes.
Consistent observations and measurements are essential when comparing habitats. Researchers should document the same relevant features, such as vegetation layers, substrate types, shelter, gaps, and spatial arrangement, using standardized approaches. Comparable records make it easier to distinguish genuine differences in habitat structure from differences caused by inconsistent sampling, supporting reliable monitoring and environmental assessment.
The resulting structural data support biodiversity monitoring, comparison of habitats, restoration planning, and evaluation of environmental change. Managers can use the information to identify how habitat structure relates to ecological communities and to examine whether restoration or disturbance is associated with structural differences. These applications connect physical habitat observations with decisions about environmental management and conservation.
