Summary Fundamental ecological research is both intrinsically interesting and provides the basic knowledge required to answer applied questions of importance management natural world. The 100th anniversary British Ecological Society in 2013 an opportune moment reflect on current status ecology as a science look forward high‐light priorities for future work. To do this, we identified 100 important fundamental pure ecology. We elicited from ecologists working across wide range systems...
Summary 1. It is widely accepted that the arrival order of migratory birds correlated with condition birds, which leads to high quality individuals occupying prime sites. However, theoretical backgrounds for this argument have been lacking. A simple game‐theoretic model timing provided investigates evolutionary stability condition‐dependent in territorial migrant birds. 2. Competition territories or other priority‐dependent benefits can lead dates far preceding cost‐minimizing date (the...
Some individuals (helpers) in cooperatively breeding species provide alloparental care and often suppress their own reproduction. Kin selection is clearly an important explanation for such behaviour, but a possible alternative group augmentation where survive or reproduce better large groups it therefore pays to recruit new members the group. The evolutionary stability of currently disputed. We model evolutionarily stable helping strategies by following dynamics social with varying degrees...
Sexual reproduction is associated with the evolution of anisogamy and sperm-producing males egg-laying females. The ensuing competition for mates has led to sexual selection coevolution sexes. Mathematical models are extensively used test plausibility different complicated scenarios traits. Unfortunately, diversity now itself equally bewildering. Here we clarify some current debate by reviewing evolutionary explanations relationship between anisogamy, potential reproductive rates, parental...
The evolution of mate choice for genetic benefits has become the tale two hypotheses: Fisher's 'run–away' and 'good genes', or viability indicators. These hypotheses are often pitted against each other as alternatives, with evidence that attractive males sire more viable offspring interpreted support good genes a negative null relationship between mating success sons components fitness favouring Fisher process. Here, we build general model female indirect captures essence both 'Fisherian'...
Dispersal is often risky to the individual, yet long-term survival of populations depends on having a sufficient number individuals that move, find each other, and locate suitable breeding habitats. This tension has consequences rarely meet our conservation or management goals. particularly true in changing environments, which makes study dispersal urgently topical world plagued with habitat loss, climate change, species introductions. Despite difficulty tracking mobile over potentially vast...
Avoidance of incestuous matings is widely reported across many animal taxa, and the adaptive value such behavior explained through inbreeding depression. However, an old somewhat neglected theoretical result predicts that inbred offer another, positive effect on inclusive fitness parents: individual who mates with a relative will help to spread genes identical by descent. This benefit can be substantial, if additional mating achieved does not harm his success otherwise, in context selfing...
Previously developed models of reproductive skew have overlooked one the main reasons why subordinates might remain in a group despite restricted opportunities to breed: possibility social queuing, i.e. acquiring dominant status future. Here, we present dynamic ESS model animal societies that incorporates both immediate and future fitness consequences decisions taken by members, based on their probability surviving from season next (when post–breeding survival probabilities drop zero, our...
Biases in the operational sex ratio (OSR) are seen as fundamental reason behind differential competition for mates two sexes, and a strong determinant differences choosiness. This view has been challenged by Kokko Monaghan, who argue that sex-specific parental investment, mortalities, mate-encounter rates quality variation determine mating system way is not reducible to OSR. We develop game-theoretic model of choosiness, signalling care, examine (i) whether results Monaghan remain robust...
The relative roles of ecological constraints, the benefits philopatry, and role life history continue to be debated in evolution natal philopatry cooperative breeding. We compare three routes breeding: departing search for territories as a floater, staying queuing inherit territory, or eventually shifting neighboring vacancy. Our model assumed dominance-structured population. It quantifies varying-rank subordinates contrasts it against benefit dispersal. apply data on Siberian jay Perisoreus...
Our current understanding of the operation sexual selection is predicated on a sex difference in parental investment, which favours one becoming limiting and choosy over mates, other competitive nonchoosy. This reflected operational ratio (OSR), sexually receptive males to females, considered be fundamental importance predicting direction selection. Difficulties measuring OSR directly have led use potential reproductive rates (PRR) as measure level investment offspring females. Several...
