Animals construct and inhabit nests that can exhibit dramatic intra- interspecific variation due to differences in behaviour, the biotic abiotic environment, evolutionary history. In ants, nest architecture reflects both ecology collective behaviour of colonies live nests. Each component (such as depth, number, size connectivity chambers) selective pressures for different functions, or structural constraints are imposed by environment To determine potential drivers structure subterranean nests, we performed a meta-analysis measures published ant compare elements within across species. We complemented this survey with 42 casts two closely related quantified features potentially impact foraging examined whether phylogeny strategy better explanatory variables observed. found explained than Our work reveals importance shaping provides an important foundation future investigations into have shaped architecture. This article is part theme issue ‘The nests: cross-taxon approach’.

Abstract The bewildering courtship phenotypes of male birds paradise ( Paradisaedae ) represent a classic example sexual selection through mate choice. While the majority studies have focused on either choice or intrasexual competition, males across variety taxa adopt alternative mating tactics as additional means obtaining fertilization when they are otherwise unable to. For example, various polygynous birds, subordinate engage in sneak copulations, which may offset fitness costs prolonged periods. Despite exhibiting strong skews and delayed plumage maturation, reports copulation exceedingly rare. After reviewing an extensive video collection interactions, we found examples mountings by female‐plumaged three species: Western parotia Parotia sefilata , Carola's carolae magnificent bird Cicinnurus magnificus . homosexual females been documented previously Lawes' P. lawesii adult violently attacked intruding attempting to mount receivers, suggesting that be immature engaging tactics. Overall, rare footage described here is suggestive two fascinating, yet unexplored phenomena birds: female behaviour.

Understanding sexual communication requires assessing the behaviour of both sender and receiver. Receiver responses to displays carry relevant information, but such signals or cues may be subtle therefore technically challenging investigate. Here, we focus on receiver body movements in response high-intensity courtship spotted bowerbirds ( Ptilonorhynchus maculatus ). Male perform a vigorous choreography dedicated display structures—bowers. Bower owners tolerate other non-territorial males at their bowers, yet these so-called ‘subordinate’ rarely result successful copulations. Males that high intensity are preferred by females this species, excessively aggressive threatening, hence scaring prospective mates away. In study, hypothesized bower better able exhibit without startling audience compared with subordinate males. To address question, used combination behavioural coding AI-based tracking movements, which allows precise spatial temporal resolution for study responses. Contrary our predictions, found evoked stronger startle than We discuss unexpected results suggest further experimental approaches future investigations.
