Abstract

Social animals make behavioural decisions based on local habitat and conspecifics, as well as memorized past experience (i.e. 'familiarity') with habitat and conspecifics. Here, we develop a conceptual and empirical understanding of how spatial and social familiarity fit within the spatial–social interface—a novel framework integrating the spatial and social components of animal behaviour. We conducted a multi-scale analysis of the movements of GPS-collared plains bison (Bison bison, n = 66) residing in and around Yellowstone National Park, USA. We found that both spatial and social familiarity mediate how individuals respond to their spatial and social environments. For instance, individuals with high spatial familiarity rely on their own knowledge as opposed to their conspecifics, and individuals with high social familiarity rely more strongly on the movement of conspecifics to guide their own movement. We also found that fine-scale spatial and social phenotypes often scale up to broad-scale phenotypes. For instance, bison that select more strongly to align with their nearest neighbour have larger home ranges. By integrating spatial and social familiarity into the spatial–social interface, we demonstrate the utility of the interface for testing hypotheses, while also highlighting the pervasive importance of cognitive mechanisms in animal behaviour. This article is part of the theme issue 'The spatial–social interface: a theoretical and empirical integration'. [ABSTRACT FROM AUTHOR]

Abstract

Ce chapitre intitulé « Quelques constats de la revue de littérature sur le concept d’impact : applications à la gestion des impacts sociaux, économiques et environnementaux par les propriétaires d’actifs immobiliers » est extrait du recueil de textes : Penser l’immobilier autrement : nouvelles perspectives en recherche (2023). Les auteurs présentent la synthèse des résultats d'une revue de littérature menée dans le cadre d'un projet de recherche sur l'intégration de la gestion des impacts sociaux, économiques et environnementaux (SEE) dans la gouvernance et la gestion des risques ESG des propriétaires d'immeubles. Le projet visait à réaliser une étude bibliométrique du concept d'impact et à analyser son lien avec la gouvernance, la gestion des risques et les enjeux ESG des entreprises. L'article aborde l'évolution de la gouvernance des entreprises depuis les années 1990, mettant en évidence le passage de la maximisation de la valeur des actionnaires à l'approche des parties prenantes, avec une attention croissante portée aux enjeux environnementaux, sociaux et de gouvernance (ESG). Il souligne également l'influence des avancées scientifiques sur les modes de gouvernance et les modèles d'affaires des entreprises et des investisseurs, se rapprochant du concept de triple reddition de compte. Les objectifs de la recherche étaient de comprendre l'évolution du concept d'impact et son application potentielle aux modes de gouvernance et aux modèles d'affaires des propriétaires et investisseurs immobiliers, confrontés aux défis du développement durable et de la lutte contre les changements climatiques. La méthodologie de la recherche comprenait une revue de la littérature narrative exploratoire utilisant la base de données Scopus et des sources secondaires pour les documents publics. La revue était structurée en trois parties, couvrant les origines étymologiques du concept d'impact, une analyse bibliométrique, et une revue documentaire sur l'utilisation du concept dans des d

Abstract

COVID-19 lockdowns in early 2020 reduced human mobility, providing an opportunity to disentangle its effects on animals from those of landscape modifications. Using GPS data, we compared movements and road avoidance of 2300 terrestrial mammals (43 species) during the lockdowns to the same period in 2019. Individual responses were variable, with no change in average movements or road avoidance behavior, likely due to variable lockdown conditions. However, under strict lockdowns, 10-day 95th percentile displacements increased by 73%, suggesting increased landscape permeability. Animals' 1-hour 95th percentile displacements declined by 12%, and animals were 36% closer to roads in areas of high human footprint, indicating reduced avoidance during lockdowns. Overall, lockdowns rapidly altered some spatial behaviors, highlighting variable but substantial impacts of human mobility on wildlife worldwide.

Abstract

Cyclic adenosine monophosphate (cAMP) plays a crucial role as a signaling molecule for capacitation, motility, and acrosome reaction in mammalian spermatozoa. It is well‐known that cAMP degradation by phosphodiesterase (PDE) enzyme has a major impact on sperm functions. This study was undertaken to characterize cAMP‐PDE activity in bovine spermatozoa. Total cAMP‐PDE activity in cauda epididymal and ejaculated spermatozoa was 543.2 ± 49.5 and 1252.6 ± 86.5 fmoles/min/106 spermatozoa, respectively. Using different family‐specific PDE inhibitors, we showed that in cauda epididymal and ejaculated spermatozoa, the major cAMP‐PDE activity was papaverine‐sensitive (44.5% and 57.5%, respectively, at 400 nm, papaverine is a specific inhibitor of the PDE10 family). These data are supporting the functional presence of PDE10 in bovine spermatozoa and were further confirmed by western blot to be PDE10A. Using immunocytochemistry, we showed immunoreactive signal for PDE10A present on the post‐acrosomal region of the head and on the flagella of ejaculated spermatozoa. Using papaverine, we showed that it promotes tyrosine phosphorylation of sperm proteins, phosphorylation of Erk1 and Erk2, and Ca²+ release from Ca²+ store. These results suggest that PDE10 is functionally present in bovine spermatozoa and is affecting different molecular events involved in capacitation, most probably by cAMP local regulation.

17. Sociality helps mitigate anthropogenic risks: Evidence from elk crossing a major highway.

Author

Poulin MP, Cherry SG, and Merkle JA

Abstract

Phenotypic variation among individuals scales up when they associate with others, creating variation within and among groups that can shape group-level outcomes such as when and where groups move. While sociality is thought to be a fitness-rewarding behaviour, empirical evidence supporting how it influences individual behaviour and the resulting fitness consequences (e.g. risk experienced) remains limited, especially in the context of human-modified landscapes. Here, we use empirical observations to test whether sociality helps animals cross busy roads. Our data came from free-ranging elk in a population where >75% of the adults were tracked, and in which group size and composition were highly variable. We combined field observations with GPS collar data to quantify four social phenotypes of individuals and groups: dominance (initiation of successful agonistic interactions), social connectedness (number and importance of social connections), social familiarity (frequency of association with group members in the past) and social stability (time since fusion with group members). We then investigated how these four social phenotypes influenced an individual's probability of crossing a major highway and tested if particular social phenotypes made better road crossing decisions (i.e. crossed at lower traffic volume). We found that who is in a group shapes the behaviour of group members around anthropogenic risks. Individuals in groups that were more dominant, more connected, and, to a lesser extent, more familiar had a lower probability of crossing the highway. Individuals that had spent more time with group members had a higher probability of crossing the highway. Importantly, our results suggest that sociality plays a role in safe movements around anthropogenic risks. Individuals in highly connected and familiar groups were less likely to cross the highway at high traffic volumes. Our work provides empirical evidence that sociality influences the movements of group-living individuals through anthropogenic disturbances and helps individuals mitigate the risks associated with such disturbances. Developing a comprehensive understanding of animal sociality in human-modified landscapes is especially important as social behaviours are simultaneously threatened by human disturbances, which could be particularly detrimental for group-living species if those same behaviours help individuals mitigate risks., (© 2025 The Author(s).
