Concepts

The interaction between a host organism and its pathogen, where genes in the host that express resistance and genes in the pathogen that express virulence are highly specific and correspond to each ot...

Water movement and chemistry dynamics that maintain fen ecosystems and support specialized plant communities

Movement of individuals into a population from external sources

Reduction in immune system function often caused by parasites or stress

Learning motor routines that mediate nectar extraction through robbing holes

A conserved nutrient-sensing signaling pathway that regulates cellular metabolism, survival, proliferation, and growth as well as reproduction

Cannibalism occurring between different age cohorts, where older individuals consume younger individuals of the same species

Water storage transfer between seasons, particularly winter snow storage contributing to summer flows

Lateral movement of snowmelt downgradient through soil zone toward topographic convergent zones to form streams

Behavioral interactions between marmots and other species sharing their habitat

Decomposition of litter isolated from tree canopy and root network influences to study selective pressures from litter chemistry alone

Regulation essential for photosynthesis, respiration, and water retention that impacts plant energy balance

Intricate networks of veins built from lignified xylem and phloem tissue that serve multiple functions including transport of water and sugars, mechanical support, and herbivory resistance

Social learning mechanism where individuals are attracted to a location simply by others being present, rather than learning specific manipulative tasks

Communication between plant tissues over distances that affects reproductive processes, such as between pollen tubes and ovarian tissues

Viral replication strategy resulting in immediate host cell lysis and viral progeny release

A nutrient-sensing pathway where mTOR kinase can be activated by amino acids and regulates cellular processes at the lysosome

The process by which macroinvertebrates establish populations on new substrate

The oxidation and reduction reactions of manganese in aquatic sediments, influenced by oxygen availability and organic carbon supply

Reduction in metabolic rate that can be active or passive

Soil microorganisms that consume nitrogen when carbon is added, affecting plant nutrient availability

Protection of local environmental conditions from broader regional climate trends by fine-scale topographic features

Associations between organic compounds and reactive minerals that can effectively protect organic compounds from microbial access and represent an important C storage mechanism in upland soil systems
