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.

Network analysis was applied to evaluate the association of various ecological microbial communities, such as soil, water and rhizosphere. Presented here is a protocol on how to use the WGCNA algorithm to analyze different co-occurrence networks that may occur in the microbial communities due to different ecological environments.

In some cases, like the 2005 Banda Ache earthquake in Indonesia, the damage involved large geographic areas and casualties in the six figures. In general, the number and intensity of earthquakes is not increasing, however, the vulnerability of the built environment is...
FAQs
Vertical layers can produce different microhabitats by changing light, temperature, moisture, movement conditions, and access to food or refuge. Organisms may therefore occupy particular levels when those conditions match their requirements. Examining variation among layers helps biologists connect spatial patterns with resource availability and shelter, rather than treating the habitat as environmentally uniform.
Variation in vegetation or substrate complexity can create multiple conditions within a site, including differences in shelter, moisture, light, and movement pathways. Those contrasts may separate organisms spatially, alter access to food or refuge, and shape interactions among community members. Measuring complexity helps link physical habitat variation to biodiversity, behavior, and community dynamics.
Comparing habitat structure among sites can show whether differences in organism occurrence, resource access, behavior, or community composition coincide with physical arrangement. Researchers can examine vegetation, substrate, water, shelter, and vertical layers across locations, then relate those measurements to observed biological patterns. This approach helps reveal whether a habitat association is consistent across environments.
These features can alter light, temperature, moisture, movement, and access to food or refuge at a local scale. Their arrangement helps determine which microhabitats are available and can affect where organisms occur, how they behave, and how they interact. Considering several features together is important because one physical attribute may not explain biological patterns by itself.
A field survey can document the presence and arrangement of vegetation, substrate, water, shelter, and vertical layers at selected sites. Researchers may also measure vegetation or substrate complexity and compare resource availability among locations. These observations provide a structured basis for relating physical conditions to organism occurrence, behavior, population distribution, or community patterns.
Habitat quality can be evaluated by examining whether a site's physical features provide the light, temperature, moisture, movement conditions, food access, and refuge associated with the organisms being studied. Comparing these attributes with organism occurrence or resource availability helps researchers identify relationships between site condition and biological use, supporting more informed assessments across locations.
In conservation research, measurements of habitat structure help evaluate how disturbance or restoration changes habitat quality and biological patterns. Researchers can compare sites or conditions to determine whether vegetation, substrate, shelter, water, or layering correspond with differences in biodiversity, population distribution, behavior, or community dynamics. This makes the approach useful for tracking ecological consequences and restoration outcomes.
