  • theory
  • Here we develop a body of ecological theory to help us understand microbiome stability. (ox.ac.uk)
  • Theory that incorporates environmental heterogeneity influenced by the assembling community and additional empirical work is needed to determine when heterogeneity intrinsic to the assembling community will result in different assembly outcomes compared with heterogeneity extrinsic to the community composition.

  • temperature
  • Climate change is impacting environmental conditions, especially with respect to temperature and ice cover in high latitude regions. (bioportfolio.com)
  • Considering the various unknowns related to prebiotic chemical networks in early Earth and the dependence of reaction rates to environmental properties such as temperature and pressure variations, we argue that homochirality could have been achieved from moderate amounts of chiral selectivity in the reaction rates.

  • important
  • Understanding how multiple environmental stressors interact to affect seagrass health (measured as morphological and physiological responses) is important for responding to global declines in seagrass populations. (jove.com)
  • As a priority habitat the nature of the impacts described on M. modiolus communities are important to the development of conservation management policy and indicators of condition in Marine Protected Areas (EU Habitats Directive) as well as indicators of Good Environmental Status under the European Union Marine Strategy Framework Directive.

  • challenges
  • In Drosophila melanogaster , as in other insects, a waxy layer on the outer surface of the cuticle, composed primarily of hydrocarbon compounds, provides protection against desiccation and other environmental challenges. (jove.com)
  • Results provide an insight into how different populations respond physiologically to various environmental challenges. (jove.com)
  • samples
  • Assays of extracellular enzyme activity in environmental samples typically involve exposing the samples to artificial colorimetric or fluorometric substrates and tracking the rate of substrate hydrolysis. (jove.com)
