phenomenon

prey aggregation

The clustering of prey organisms in particular locations or habitats

community ecology1 paper
phenomenon

primitively eusocial

phenomenon

pseudoflower formation

Developmental hijacking where infected plants produce bright yellow flower-like clusters that mimic co-occurring blooms to attract pollinators for pathogen reproduction

population ecology1 paper
phenomenon

puddling behavior

A form of supplemental feeding for nectivorous Lepidoptera to acquire necessary mineral nutrients, primarily sodium, that are otherwise absent from their nectar diets

population ecology1 paper
phenomenon

quantitative resistance

Plant defense that reduces but does not eliminate herbivore performance, mediated by multiple genes with additive effects

population ecology1 paper
phenomenon

rarity

Species characterized by low local abundance and small geographic range size

community ecology1 paper
phenomenon

redox gradients

Sharp redox gradients that favor the generation of ROS, created by mixing between waters with largely different chemical compositions

phenomenon

redox microsites

Non-majority spatially heterogeneous soil volumes possessing conditions differing from the bulk matrix, where internal oxygen consumption exceeds the rate of oxygen supply

phenomenon

reproductive cycle variation

Seasonal changes in ant colony composition between sexual and worker ant production phases

population ecology1 paper

residual layer

Remnant of previous day's mixed layer that persists aloft after surface cooling and formation of stable nocturnal boundary layer

climate1 paper
phenomenon

resource availability

The availability of food resources which may affect severity of ectoparasitic infestation, manipulated through food supplementation treatments

scale-free networks

Networks where the degree distribution follows a power law, giving similar properties such as robustness to random removal of individuals

methodological1 paper
phenomenon

seasonal isolation

Periods when remote ecosystems become inaccessible due to winter conditions like snow and ice cover

phenomenon

seasonal streamflow variation

Variations in water quality concentrations due to observed seasonal streamflow fluctuations, with smaller concentrations noted through the 1980-81 period for sampling sites downstream from mine draina...

phenomenon

sensor drift

methodological1 paper
phenomenon

sex-specific climate response

Differential responses between sexes to environmental variation potentially creating imbalance in the frequency of males and females

climate1 paper
phenomenon

sexual dimorphism in immune response

Marked differences between sexes in immune response, with males often having smaller spleens and higher testosterone levels linked to immunosuppression
