There is now abundant evidence for a role of social learning and culture in shaping behaviour range avian species across multiple contexts, from migration routes geese foraging crows, to passerine song. Recent emerging has further linked fitness outcomes some birds, highlighting its potential importance conservation. Here, we first summarize the state knowledge on focusing best-studied contexts migration, foraging, predation We identify extensive gaps taxa but argue that existing suggests that: (i) are taxonomically clustered (ii) reliance one behavioural domain does not predict others. Together, use this build predictive framework aid conservationists species-specific decision-making under imperfect knowledge. Second, review link between conservation birds. understanding which behaviours birds likely learn socially can help refine strategies, improving trajectories threatened populations. Last, present practical steps how consideration be integrated into actions including reintroductions, translocations captive breeding programmes.This article part theme issue 'Animal culture: changing world'.

Abstract We implemented Machine Learning (ML) techniques to advance the study of sperm whale ( Physeter macrocephalus ) bioacoustics. This entailed employing Convolutional Neural Networks (CNNs) construct an echolocation click detector designed classify spectrograms generated from acoustic data according presence or absence a click. The achieved 99.5% accuracy in classifying 650 spectrograms. successful application CNNs clicks reveals potential future studies train CNN-based architectures extract finer-scale details cetacean Long short-term memory and gated recurrent unit neural networks were trained perform classification tasks, including (1) “coda type classification” where we obtained 97.5% categorizing 23 coda types Dominica dataset containing 8,719 codas 93.6% 43 Eastern Tropical Pacific (ETP) with 16,995 codas; (2) “vocal clan 95.3% for two classes 93.1% four ETP types; (3) “individual identification” 99.4% using whales. These results demonstrate feasibility applying ML bioacoustics establish validity constructing learn meaningful representations vocalizations.

The zone of latent solutions and its relevance to understanding ape cultures

Biology & Philosophy, Год журнала: 2020, Номер 35(5)

Опубликована: Окт. 1, 2020

Abstract The zone of latent solutions (ZLS) hypothesis provides an alternative approach to explaining cultural patterns in primates and many other animals. According the ZLS hypothesis, non-human great ape (henceforth: ape) cultures consist largely or solely solutions. current competing (and predominant) for culture argues instead that at least some their behavioural artefact forms are copied through specific social learning mechanisms (“copying hypothesis”) may depend on copying (copying-dependent forms). In contrast, does not require these be copied. Instead, it suggests several (non-form-copying) help determine frequency (but typically form) behaviours artefacts within connected individuals. thus increases stabilisations a particular behaviour’s artefact’s can derive from socially-mediated (cued) form reinnovations. Therefore, while genes ecology play important roles as well, according apes acquire individually, but usually socially induced do so (provided sufficient opportunity, necessity, motivation timing). is often criticized—perhaps also because challenges null which assumes requirement form-copying explain (and/or artefact) forms. However, new approach, with less accumulated literature compared confusion expected. Here, we clarify approach—also relation hypotheses—and address misconceptions objections. We believe clarifications will provide researchers coherent theoretical experimental methodology examine necessity variants apes, humans species.

Bioacoustic monitoring of animal vocal behavior for conservation

Conservation Science and Practice, Год журнала: 2019, Номер 1(8)

Опубликована: Июнь 11, 2019

Abstract The popularity of bioacoustics for threatened species monitoring has surged. Large volumes acoustic data can be collected autonomously and remotely with minimal human effort. approach is commonly used to detect cryptic and, more recently, estimate abundance or density. However, the potential conservation‐relevant information derived from signatures associated particular behavior less well‐exploited. Animal vocal reveal important about critical life history events. In this study, we argue that overlap disciplines bioacoustics, communication, conservation behavior—thus, “acoustic behavior”—has much offer monitoring. particular, vocalizations serve as indicators behavioral states contexts provide insight into populations it relates their conservation. We explore available species' relate reproduction recruitment, alarm defense, social behavior, how could translate benefits. While there are still challenges processing data, conclude may improve where behaviors informative management decision‐making.

Abstract Human activities are altering natural areas worldwide. While our ability to map these at fine scales is improving, a simplistic binary characterization of habitat and non‐habitat with focus on change in extent has dominated conservation assessments across different spatial scales. Here, we provide metric that captures both loss, quality fragmentation effects which, when combined, call intactness. We identify nine categories intactness the world's terrestrial ecoregions based changes 16‐year period. found highly impacted degraded predominant (74%) just 6% improving trajectories. It essential management degrading processes be targeted international agendas order ensure Earth's remaining intact ecosystems effectively conserved restored achieve effective outcomes.

Blind alleys and fruitful pathways in the comparative study of cultural cognition

Physics of Life Reviews, Год журнала: 2022, Номер 43, С. 211 - 238

Опубликована: Окт. 21, 2022

A mere few decades ago, culture was thought a unique human attribute. Evidence to the contrary accumulated through latter part of twentieth century and has exploded in present one, demonstrating transmission traditions social learning across all principal vertebrate taxa even invertebrates, notably insects. The scope is nevertheless highly distinctive. What makes our cultural capacities their cognitive underpinnings so different? In this article I argue that behavioural scientists' endeavours answer question, fruitful research pathways ensuing discoveries have come exist alongside popular, yet light current empirical evidence, questionable scenarios scientific blind alleys. particularly re-evaluate theories rely on centrality supposed uniquely capacity for imitative copying explaining distinctive massive cumulative evolution (CCE) species. most extreme versions perspective suffer logical incoherence severe limits testability.

Local genetic adaptation to habitat in wild chimpanzees

Science, Год журнала: 2025, Номер 387(6730)

Опубликована: Янв. 9, 2025

How populations adapt to their environment is a fundamental question in biology. Yet, we know surprisingly little about this process, especially for endangered species, such as nonhuman great apes. Chimpanzees, our closest living relatives, are particularly notable because they inhabit diverse habitats, from rainforest woodland-savannah. Whether genetic adaptation facilitates habitat diversity remains unknown, despite it having wide implications evolutionary biology and conservation. By using newly sequenced exomes 828 wild chimpanzees (388 postfiltering), found evidence of fine-scale habitat, with signatures positive selection forest the same genes underlying malaria humans. This work demonstrates power noninvasive samples reveal adaptations highlights importance adaptive chimpanzees.
