Abstract:
... The ability to innovate and the social transmission of innovations have played a central role in human evolution. However, innovation is also crucial for other animals, by allowing them to cope with novel socioecological challenges. Although innovation plays such a central role in animals’ lives, we still do not know the conditions required for innovative behaviour to emerge. Here, we focused on i ...

Antirrhinum majus; Bombus terrestris; Lupinus; Tecoma; bees; color; energy; flower morphology; flowers; forage; foraging; insect flight; odors; pollination; pollinators
Abstract:
... Foraging bees expend considerable time and energy handling flowers that are morphologically complex (with concealed food rewards) while simple flowers (with readily available rewards) bloom simultaneously in their foraging environment. Previous studies have investigated the consequences of floral morphology for both foragers and plants, often treating ‘complex’ and ‘simple’ morphologies as dichoto ...

Subject:
Tamias sibiricus; animal behavior; animals; ecosystems; food availability; germination; interspecific competition; nests; seeds; trees
Abstract:
... The rapid sequestering hypothesis predicts that scatter-hoarding animals quickly sequester food items by storing seeds in caches near seed sources to reduce competition. However, tests of this hypothesis usually use food-hoarding animals with a single load or a small load size. How multiple-load animals place their caches between food sources and nests remains largely unknown. Here, we hypothesize ...

Subject:
Aceria tosichella; animal behavior; phenotype; phytophagous mites; wind speed; wind tunnels
Abstract:
... Dispersal involves many behavioural interactions that if inefficient or ineffectual would lead to serious fitness consequences. Such costs would be particularly dear for passively dispersing organisms for which direction of movement is determined by external forces. In this study, we investigated whether environment and morphology influence dispersal behaviours of a passive, aerially dispersing or ...

Ammodramus savannarum; biogeography; breeding; brood parasitism; case studies; dispersal behavior; grasslands; nests; parents; predation; reproductive success; songbirds; Kansas
Abstract:
... Understanding the causes and consequences of dispersal is key to identifying selective pressures underlying species-level variation in biogeography, metapopulation dynamics and adaptive capacity. We tested the hypotheses that nest predation and/or brood parasitism avoidance drive breeding dispersal decisions and that dispersal functions to reduce subsequent reproductive failure in grasshopper spar ...

Syngnathus scovelli; age structure; animal behavior; courtship; fecundity; females; males; mating competitiveness; phenotype; pregnancy
Abstract:
... Within Syngnathidae (pipefish, seadragons and seahorses), male pregnancy often results in choosy males and competitive females. Females in these species often evolve secondary sexual traits and engage in courtship displays that make their ornaments more noticeable to males. Most syngnathids probably continue to grow larger throughout their lives, but we know little about the relationship between a ...

Subject:
Gallus gallus; chickens; chicks; computer simulation; foraging; forest litter; habitats; mimicry (behavior); pecking; predators; risk
Abstract:
... Prey and ambush predators that rely on concealment face a major constraint: motion breaks their camouflage. However, dappled light is a common feature of sunny, vegetated habitats and can, when conditions are windy, become a source of dynamic visual noise. We tested the idea that this could mask movement, reducing the risk of detection. Newly hatched domestic fowl chicks, Gallus gallus domesticus, ...

Abstract:
... Reproductive success is often highly skewed in animal populations. Yet the processes leading to this are not always clear. Similarly, connections in animal social networks are often nonrandomly distributed, with some individuals with many connections and others with few, yet whether there are simple explanations for this pattern has not been determined. Numerous social interactions involve dyads e ...

Passerculus sandwichensis; adults; information sources; juveniles; learning; prediction; social behavior; songbirds; vocalization; young animals
Abstract:
... Animals often live within close proximity of multiple conspecific individuals, allowing them to eavesdrop on other animals' signalling interactions to guide their own social behaviours. For a young animal that is learning to vocalize, eavesdropping on vocal interactions between adults may provide a rich source of information: young animals might preferentially learn vocalizations that are commonly ...

Abstract:
... Although inbreeding depression in life-history traits has been well characterized, inbreeding effects on mating behaviour and sexually selected traits have been less well studied. Here, we assess levels of inbreeding depression in a number of fitness-related reproductive parameters of female decorated crickets, Gryllodes sigillatus. We predicted that due to direct negative effects of inbreeding an ...

Cyanistes caeruleus; behavior change; breeding season; clutch size; fledglings; hatching; mortality; nests; paternity; predation; prey species; reproductive behavior; reproductive performance; reproductive success; risk perception
Abstract:
... An increase in the perceived risk of predation triggers many behavioural changes in prey species, which can have consequences for their reproductive success. Perceived predation risk may also influence investment in extrapair activities and, as a result, the frequency of extrapair paternity (EPP), but this possibility remains largely untested. Here we report on a study of a small passerine bird, t ...

Poecilia reticulata; evolution; females; fish behavior; genetic variation; heterozygosity; inbreeding; males; mating behavior; phenotype; pleiotropy; progeny; risk reduction
Abstract:
... Many animals, from humans to invertebrates, exhibit sexual preference for unfamiliar partners. This may reduce the risk of inbreeding and increase offspring heterozygosity. An alternative less tested hypothesis is that selection for neophilia in other contexts (e.g. exploration of unfamiliar environments) may promote mate preference for unfamiliar partners. We tested whether exploratory tendency c ...

Subject:
Poecilia reticulata; animals; decision making; fish behavior; fish communities; group size; memory
Abstract:
... Animals tend to learn and make decisions inductively, and simple, individual-level behavioural decisions can scale up to yield interesting emergent properties at the population level. The minority game is a theoretical formulation based on the principle of inductive learning, wherein a group of individuals, each facing two equivalent choices, self-organize to achieve maximum coordination. Coordina ...

Tadarida; echolocation; flight; sonar
Abstract:
... How bats mitigate mutual interference is a long-standing question that has ecological and technological implications as biosonar systems continue to outperform artificial sonar systems in noisy, cluttered environments. Echolocating bats display a mutual suppression response, slowing their pulse emission rates when flying in groups to gain a net improvement in sonar performance. However, flight pat ...

Gasterosteus aculeatus; Pheidole; adaptive radiation; animal behavior; fish; phenotype; phylogeny
Abstract:
... Behavioural phenotypes are notable for their plasticity, in that individual behaviour patterns can be expressed ephemerally in response to an appropriate stimulus and then disappear. In the absence of an appropriate stimulus, behavioural phenotypes can remain unexpressed over many generations, yet the capacity to perform the behaviour can be retained. Here we discuss potential evolutionary influen ...

Abstract:
... One of the most effective defensive strategies of hosts against brood parasites is rejection, commonly achieved by ejection of the parasitic egg or desertion of the parasitized nest. Nest desertion should be a costlier strategy than egg ejection, because birds must thesn spend additional time and energy renesting, and therefore we still cannot explain why some individuals desert their nests rather ...

animal behavior; cognition; courtship; decision making; diet; ecology; food choices; foraging; learning; optimal nutrition; prediction
Abstract:
... A major focus of research in behavioural ecology involves testing whether behaviour, on average, is adaptive. Here, we note that although studies often find that individuals differ in how well they perform adaptive behaviour (e.g. some individuals fit the predictions of optimal diet theory better than others, and some exhibit higher social skill than others), few studies have emphasized these cons ...

Abstract:
... The costs and benefits that come from being part of a group have most often been categorized by their adaptive function, such as reducing predation risk or increasing foraging competition. However, collective behaviours may also be characterized by several different behavioural mechanisms. For example, individuals may have a relatively fixed attraction to any group, as well as being able to flexib ...
