Trophic cascades : the primacy of trait-mediated indirect interactions
Trophic cascades are textbook examples of predator indirect effects on ecological systems. Yet there is considerable debate about their nature, strength and overall importance. This debate stems inExpand

Factors Influencing Site Abandonment and Site Selection in a Sit-and-Wait Predator: A Review of Pit-Building Antlion Larvae
There is a large body of evidence indicating that predator behavior may strongly influence patterns and processes at the population and community level. Site selection is a major component of fitnessExpand

Plastic bet-hedging in an amphicarpic annual: an integrated strategy under variable conditions
Amphicarpy is a form of diversified bet-hedging expressed mostly in annual plants, where two types of offspring are produced with two distinct ecological roles: long-range aerial dispersers andExpand

Consequences of variation in male harem size to population persistence: Modeling poaching and extinction risk of Bengal tigers (Panthera tigris)
Abstract Poaching of tigers (Panthera tigris) and its prey base are considered important factors influencing wild tiger populations in India. At present, wild tigers are disappearing even fromExpand

Efficiency evaluation of two competing foraging modes under different conditions.
Various foraging modes are employed by predators in nature, ranging from ambush to active predation. Although the foraging mode may be limited by physiological constraints, other factors, such asExpand

Gene Expression Patterns of Oxidative Phosphorylation Complex I Subunits Are Organized in Clusters
After the radiation of eukaryotes, the NUO operon, controlling the transcription of the NADH dehydrogenase complex of the oxidative phosphorylation system (OXPHOS complex I), was broken down andExpand

A trade-off between growth and starvation endurance in a pit-building antlion
Trade-offs have a central role in evolutionary ecology and life-history theory. Here, we present evidence for the existence of a rarely studied trade-off between growth rate and starvation enduranceExpand

Ashkenazi Jewish mtDNA haplogroup distribution varies among distinct subpopulations: lessons of population substructure in a closed group
The quest for genes associated with diseases is widely recognized as an essential task in the effort to investigate the genetic basis of complex human disorders and traits. A basic stage inExpand

Individual size variation and population stability in a seasonal environment: a discrete-time model and its calibration using grasshoppers.
Much recent literature is concerned with how variation among individuals (e.g., variability in their traits and fates) translates into higher-level (i.e., population and community) dynamics. AlthoughExpand
