TLDR
Jensen's inequality is a mathematical proof that is seldom mentioned in the ecological literature but which provides a powerful tool for predicting some direct effects of environmental variance in biological systems.Abstract:
Many biologists now recognize that environmental variance can exert important effects on patterns and processes in nature that are independent of average conditions. Jensen’s inequality is a mathematical proof that is seldom mentioned in the ecological literature but which provides a powerful tool for predicting some direct effects of environmental variance in biological systems. Qualitative predictions can be derived from the form of the relevant response functions (accelerating versus decelerating). Knowledge of the frequency distribution (especially the variance) of the driving variables allows quantitative estimates of the effects. Jensen’s inequality has relevance in every field of biology that includes nonlinear processes.read more

Why intraspecific trait variation matters in community ecology

TL;DR: Six general mechanisms by which trait variation changes the outcome of ecological interactions are identified and synthesize recent theory and identify several direct effects of trait variation per se and indirect effects arising from the role of genetic variation in trait evolution.

TL;DR: In this paper, the impact of different gap filling methods on the annual sum of net ecosystem exchange (F NEE ) responses is investigated, based on mean diurnal variation, look-up tables (LookUp), and nonlinear regressions (Regr).

Ecological Models and Data in R
TL;DR: In step-by-step detail, Benjamin Bolker teaches ecology graduate students and researchers everything they need to know in order to use maximum likelihood, information-theoretic, and Bayesian techniques to analyze their own data using the programming language R.

Ecological consequences of genetic diversity.
TL;DR: A review of the literature reveals significant effects of genetic diversity on ecological processes such as primary productivity, population recovery from disturbance, interspecific competition, community structure, and fluxes of energy and nutrients.

Assessing the consequences of global change for forest disturbance from herbivores and pathogens.
TL;DR: This work identifies 32 syndromes of biotic disturbance in North American forests that should be carefully evaluated for their responses to climate change and suggests a list of research priorities that will allow us to refine these risk assessments and adopt forest management strategies that anticipate changes inBiotic disturbance regimes and mitigate the ecological, social, and economic risks.

Reaction kinetics of poikilotherm development.
TL;DR: A stochastic thermodynamic model of poikilotherm development has been derived from the Eyring equation assuming multiple activity states of the underlying developmental control enzymes and the resulting equation has been found applicable to a wide range of organisms.
