Many decisions in the lives of animals and humans require a fine balance between exploration different options exploitation their rewards. Do you buy advertised car, or do test drive models? continue feeding from current patch flowers, fly off to another one? marry your partner, try luck with someone else? The required these situations is commonly referred as exploration– tradeoff. It features prominently wide range research traditions, including learning, foraging, decision making literatures. Here, we integrate findings other often-isolated literatures order gain better understand- ing possible tradeoffs exploitation, propose new theoretical insights that might guide future research.

We conclude best conceptualized points continuum, extent an agent’s behavior can be interpreted exploratory exploitative depends upon level abstraction it considered.

The field of habitat ecology has been muddled by imprecise terminology regarding what constitutes habitat, and how importance is measured through use, selection, avoidance other bio-statistical terminology. Added to the confusion idea that scale-specific. Despite these conceptual difficulties, ecologists have made advances in understanding ‘how habitats are important animals’, data from animal-borne global positioning system (GPS) units potential help this clarification. Here, we propose a new framework connect with measures animal performance itself—towards assessing habitat–performance relationship (HPR). Long-term studies will be needed estimate consequences selection for performance. GPS wildlife can provide approaches studying useful correlates review. Recent examples include merging traditional resource information about resources used at different critical life-history events (e.g. nesting, calving, migration), uncovering facilitate movement or foraging and, ultimately, comparing strategies those resulting death. By integrating receivers technologies combining additional information, believe drivers HPRs inform improve conservation.

Carnivore guilds play a vital role in ecological communities by cascading trophic effects, energy and nutrient transfer, stabilizing or destabilizing food webs. Consequently, the structure of carnivore can be critical to ecosystem patterns. Body size is crucial influence on intraguild interactions, because it affects access prey resources, effectiveness scramble competition, vulnerability predation.

Abstract Habitat selection is a fundamental animal behavior that shapes wide range of ecological processes, including movement, nutrient transfer, trophic dynamics and population distribution. Although habitat has been focus studies for decades, technological, conceptual methodological advances over the last 20 yr have led to surge in addressing this process. Despite substantial literature focused on quantifying habitat‐selection patterns animals, there marked lack guidance best analytical practices. The foundations most commonly applied modeling frameworks can be confusing even those well versed their application. Furthermore, yet synthesis made yr. Therefore, need both current state knowledge selection, seeking study Here, we provide an approachable overview analyses (HSAs) conducted using functions, which are by far framework understanding This review purposefully non‐technical without heavy mathematical statistical notation, confuse many practitioners.

ABSTRACT General principles about the consequences of seed dispersal by animals for structure and dynamics plant populations communities remain elusive. This is in part because deposition patterns emerge from interactions between frugivore behaviour distribution food resources, both which can vary over space time. Here we advocate a frugivore‐centred, process‐based, synthetic approach to research that integrates ecology animal movement across multiple spatio‐temporal scales. To guide this synthesis, survey existing literature using paradigms movement. Specifically, studies are discussed with respect five criteria: selection focal organisms (animal or plant); measurement movement; characterization shadow; animal, environmental factors included study; scales study. Most focused on either frugivores plants characterized shadows directly combining gut retention time data indirectly conducting maternity analysis seeds. Although organismal traits were often measured, they seldom used characterize shadows. Multi‐scale analyses rare, mostly at fine spatial scales, single fruiting seasons, individual dispersers.
