Keeping up with environmental change: The importance of sociality

Ethology, Journal Year: 2021, Volume and Issue: 127(10), P. 790 - 807

Abstract In the current era of rapid climate change, populations are facing environments in which food availability can quickly decline or become highly unpredictable. These conditions may require a high degree flexibility individuals and to adequately respond such changes. We propose that evolution be facilitated social animals form groups cooperate important tasks critically affect survival reproduction ultimately adaptive capacity. argue sociality is likely key, yet largely overlooked factor shapes rather than limits potential for phenotypic plasticity. Cooperatively breeding species most suitable studying influence both physical environmental on shaping plasticity individuals. Cooperative breeders display variation group size structure, extent cooperation competition between their members. addition, immigrants impose costs and/or benefits other members, as well whole group. cooperative breeders, we elucidate why how formation interactions members provide some all Observed adjustments behaviour strategic enhance individual fitness benefits, thus improve population persistence.

Review of Temporary Crating of Farrowing and Lactating Sows

Frontiers in Veterinary Science, Journal Year: 2022, Volume and Issue: 9

Temporary crating (TC) provides lactating sows with the opportunity to move more freely after crate opening a few days parturition. The aim of this paper was evaluate whether TC gives overall welfare improvement when compared permanent or free farrowing. This review shows that pens allow turn during majority time in farrowing unit, it is pen design and period confinement within influence extent which different functional motivated behaviors can be fulfilled. also indicates there are at least short-term benefits reduced, as shown by reported increases such exploration interactions piglets not permanently crated. It remains unclear any longer-term beneficial effects (until beyond weaning) due paucity studies. Furthermore, uncertain observed translate other indicators. Research findings indicate no reduction frequency stereotypies body lesions do provide clear answer regarding sow stress response released from confinement. Compared farrowing, appears for reducing piglet mortality. impact onset on process mortality have been inconsistent. While before prevents nest building behavior, consequences physiology ambiguous. Confining briefly may best compromise, allowing perform nest-building but risks crushing unconfined increase. Subsequent reopening seems increase only if done earlier than 3-5 methodological considerations, proposal consistent accurate terminology describing systems highlights gaps knowledge. In conclusion, step forward better pig crate, allows some freedom movement without impairing welfare. However, comprehensive research needed draw sound conclusions viable transition

How does early‐life adversity shape telomere dynamics during adulthood? Problems and paradigms

BioEssays, Journal Year: 2022, Volume and Issue: 44(4)

Published: Feb. 5, 2022

Abstract Although early‐life adversity has been associated with negative consequences during adulthood, growing evidence shows that such can also lead to subsequent stress resilience and positive fitness outcomes. Telomere dynamics are relevant in this context because of the link developmental conditions longevity. However, few studies have assessed whether effects on telomere may relate adult dynamics. We propose potential links between could be driven by constraints (the Constraint hypothesis), nature/severity Resilience or developmental‐mediated changes individual life‐history strategies Pace Life hypothesis). discuss these non‐mutually exclusive hypotheses, explore future research directions, specific test hypotheses. Our article aims expand our understanding evolutionary role dynamics, ageing.

Familiarity, age, weaning and health status impact social proximity networks in dairy calves

Scientific Reports, Journal Year: 2023, Volume and Issue: 13(1)

Published: Feb. 8, 2023

Social network analysis in dairy calves has not been widely studied, with previous studies limited by the short study duration, and low number of animals replicates. In this study, we investigated social proximity interactions 79 Holstein-Friesian from 5 cohorts for up to 76 days. Networks were computed using 4-day aggregated associations obtained ultrawideband location sensor technology, at 1 Hz sampling rate. The effect age, familiarity, health, weaning status on networks was assessed. poorly correlated (non-stable) between different periods, majority them associated heterogeneously, individuals assorted based familiarity whole duration study. Age significantly increased association strength, time eigenvector centrality decreased closeness coefficient variation (CV). Sick had a lower time, CV, higher compared healthy calves. During after weaning, centrality. These results indicate that sickness have significant impact interaction

Growing up with chronic traffic noise exposure leads to transient but not long-term noise tolerance in a songbird

Biology Letters, Journal Year: 2025, Volume and Issue: 21(1)

Published: Jan. 1, 2025

Noise pollution is on the rise worldwide. An unresolved issue regarding mitigation of noise whether and at which timescales animals may adapt to pollution. Here, we tested continuous highway exposure perinatally during juvenile development increased tolerance in a songbird, zebra finch ( Taeniopygia castanotis ). Breeding pairs were exposed recordings from pre-egg-laying until their offspring reached subadulthood. Subsequently, for both as subadults adults spatial preference test, where birds could choose enter aviaries with different levels noise. Unlike control that preferentially chose quiet aviaries, noise-reared exhibited no preferences first test. However, when experimental retested after two months without exposure, they now avoided previously tolerated preferred quieter aviary. The observed directly release treatment was thus only transient. Growing up chronic did not increase subjects’ tolerance, meaning least this songbird species, adaptation unlikely arise developmental time scale.

Juvenile socio-ecological environment shapes material technology in nest-building birds

Abstract Variation in animal material technology, such as tool use and nest construction, is thought to be caused, part, by differences the early-life socio-ecological environment—that is, who what around—but this developmental hypothesis remains unconfirmed. We used a tightly controlled paradigm determine whether adult and/or raw-material access early life shape first-time construction laboratory-bred zebra finches Taeniopygia guttata at sexual maturity. found that juvenile both an unrelated raw of one color led majority preference (75%) novice builders for over either natal-nest or novel-colored material, whereas lack 4- nearly 3-fold reduction speed which initiated completed respectively.

Leveraging big data to uncover the eco-evolutionary factors shaping behavioural development

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2023, Volume and Issue: 290(1992)

Published: Feb. 1, 2023

Mapping the eco-evolutionary factors shaping development of animals’ behavioural phenotypes remains a great challenge. Recent advances in ‘big data’ research—the high-resolution tracking individuals and harnessing that data with powerful analytical tools—have vastly improved our ability to measure model developing phenotypes. Applied study ontogeny, unfolding whole repertoires can be mapped unprecedented detail relative ease. This overcomes long-standing experimental bottlenecks heralds surge studies more finely define explore behavioural–experiential trajectories across development. In this review, we first provide brief guide state-of-the-art approaches allow collection analysis We then outline how such used address key issues regarding ecological evolutionary development: developmental feedbacks between behaviour underlying states, early life effects transitions, information integration
