Habitat Fragmentation
0 Views •
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...

The Implicit Association Test

2023
Source: Julian Wills & Jay Van Bavel—New York University One of the core constructs in social psychology is the notion of an attitude toward an object or person. Traditionally, psychologists measured attitudes by simply asking people to self-report their beliefs, opinions, or feelings. This approach has limitations, however, when measuring socially sensitive attitudes, like racial prejudice, because people are often motivated to self-report unprejudiced, egalitarian beliefs (despite...

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.

Associative Learning

Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning. Classical conditioning, also known...
FAQs
Habitat association patterns emerge when several conditions act together rather than when one feature operates alone. Temperature and moisture can shape physiological suitability, while vegetation structure, food, and shelter affect survival and reproduction. Competition may further restrict access to resources, and movement across the landscape determines whether organisms can reach otherwise suitable areas.
Food and shelter provide resources that support survival and reproduction, whereas competition can influence how effectively organisms use those resources. These factors help explain why a species may occur more often in some environments than in others, even when broad physical conditions appear similar. Including them produces a more complete interpretation of distribution patterns.
Movement connects organisms with the environmental conditions and resources they need. A landscape may contain suitable temperature, moisture, vegetation, or food conditions in separate locations, so movement affects where organisms occur and how distributions appear spatially. Studying this relationship helps researchers connect habitat characteristics with observed patterns of presence, abundance, and movement.
Researchers combine field surveys with measurements of relevant environmental features. Surveys record whether organisms are present and may also assess abundance, while environmental observations characterize conditions such as temperature, moisture, vegetation structure, food availability, and shelter. Comparing these observations across locations allows researchers to examine which habitat characteristics coincide with species distributions.
Statistical models compare species presence or abundance with measured habitat characteristics, helping researchers evaluate relationships across surveyed locations. This approach organizes field observations into evidence about distribution patterns rather than relying only on individual sightings. The resulting analyses can identify important environments and support predictions about how species may respond to environmental change.
Habitat association information supports biodiversity monitoring, wildlife management, conservation planning, and habitat restoration. By identifying environments linked with species occurrence or abundance, researchers can help guide protection of ecological resources. The same information can also support predictions about responses to environmental change, making it useful for evaluating priorities across landscapes.
