- 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 ...

- 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 ...

- 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 ...

- 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 ...

- 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 ...

- 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 ...

- 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:

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 ...

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 ...

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 ...

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 ...

- 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 ...

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.

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 ...

- Abstract:

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 ...

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 ...
