Mayr's embrace of genetic coadaptation and
organismal integration, with peripatric speciation by genetic revolution its dearest offspring, is fundamental to his stormy relations with population geneticists.
Organismal factors are then discussed, including metabolism, genetics, and hormonal regulation, followed by food composition factors including macronutrient content, portion size, and solid/liquid differences.
Sparks' research seeks to determine the role of
organismal light in the aquatic realm--specifically, is the ability to produce light or to fluoresce correlated with increased species richness in the ocean?
"It seems like resources, feeding and diet are the most important factors at the initial stage," said lead author Lauren Sallan, graduate student in the Department of
Organismal Biology and Anatomy at the University of Chicago.
Phylogeny is the history of
organismal lineages as they change through time.
This series of 17 essays, rewritten from his previously published articles, applies his findings to genetic differentiation during speciation, molecular variability and hypothesis testing, methodologies such as gene trees, molecular clones within
organismal clones, aging and sexual reproduction and their relation to DNA repair, conservation genetics, the language of DNA, mating systems and natural histories, biodiversity, evolutionary biology, models and metaphors, and evolution's unanswered questions.
Although most of the faunal chapters in the Benckiser book are replete with descriptions of sampling methodology the slimmer volume of Hall (Methods for the examination of
organismal diversity in soils and sediments) provides an inexpensive source of information specifically for the collection, isolation, and culturing, where appropriate, of most organisms (from heterotrophic bacteria to mega-fauna) found in soils and sediments.

Southampton, UK) offers this careful criticism of Lovelock's Gaia hypothesis, the idea that life itself provides regulatory feedback to the geologic-climate system that keeps it habitable, analogous to
organismal homeostasis.
Any of these cases could be described as "ecological suicide," explains David Denlinger, professor of entomology and evolution, ecology and
organismal biology.
There are many records of fossilized dinosaur eggs, and even several records of fossil cocoons, but, as author Dr Jorge Genise of the Museo Argentino de Ciencias Naturales states "this is the first time that these cocoons are found closely associated with an egg." Such a study of
organismal behavior (e.g.
The ten contributions in this collection summarize current knowledge about the cellular and
organismal mechanisms that allow some plants to survive without water by drying to air equilibrium and resuming normal metabolic function on rehydration.
