Size Structure and Intraguild Interactions between Two Ambystoma Species
<p>Intraguild interactions affect population and community structure through a combination of competition and predation. Changes in size structure influence intraguild interactions by affecting the strength and direction of these species’ interactions. I tested for size-structured intraguild …

Carnivore ecology and conservation : implications for tiger conservation and management in Nepal /
… novel model to estimate prey abundance, assessed intraguild interaction between tigers and leopards in response to prey and disturbance factors, and evaluated sustainable financing mechanisms for tiger conservation programs. The success of carnivore conservation relies on better understanding …

Modeling and analysis of a three-species food web with facilitated and intraguild predation
Biotic interactions are known to shape natural community assemblages and biodiversity. Positive interactions such as facilitation have recently received attention in ecological food webs. Mechanistic models have improved our understanding of these complex food web interactions. Here, focus is given …

Ecological Assembly of Leaf-Litter Anuran Communities Across a Neotropical Land-Bridge Archipelago
… association influences the outcome of species interactions; and third, examine species co-occurrence and body size overlap patterns, assessing how differences in coloration - associated with aggressive behavior in O. pumilio - influence the assembly of leaf-litter anuran communities. In the …

Multiscale patterns of mammal diversity and occurrence in the Karoo
… was to understand how biophysical drivers and intraguild interactions have shaped the distribution of mammals at different spatial scales, relative to existing and proposed land–uses. I had three main objectives: 1) to provide a foundational understanding of the mammalian community present …

FACTORS INFLUENCING THE SPATIAL AND TEMPORAL STRUCTURE OF A CARNIVORE GUILD IN THE CENTRAL HARDWOOD REGION
… use, indicating potential for interspecific interactions. Although much is known about space use, habitat relationships, and activity patterns of the individual species separately, little is known about factors that facilitate coexistence and how interactions within this guild influence …

A DYNAMIC LANDSCAPE OF FEAR: HUMAN IMPACTS ON CARNIVORE COMMUNITIES
… community structure by altering predator-prey interactions, shifting diel activity patterns, and altering wildlife movement leading to increased sightings, nuisance reports, and harvests. To investigate how human activity influences U.S. carnivore communities, I explored variation in …

Ants and spiders in grassland food webs
… (Zikaden). Ein Experiment offenbarte starke Intraguilden Interaktionen zwischen Ameisen und Spinnen. Im Gegensatz dazu, fanden wir in einem kleinräumigen Freilandexperiment einen positiven Einfluss der Ameisenart Lasius niger auf Spinnen und ihre Beute. Eine ähnliche Wirkung von Ameisen auf …
