Abstract Network optimality has been described in genes, proteins and human communicative networks. In the latter, leads to efficient transmission of information with a minimum number connections. Whilst studies show that differences centrality exist animal networks central individuals having higher fitness, network efficiency never studied groups. Here we 78 groups primates (24 species). We found group size neocortex ratio were correlated efficiency. Centralisation (whether several are...
Abstract In many studies, flight initiation distance ( FID , the at which a prey starts to flee approach of walker) is positively related starting SD walker begins approach) and alert AD focal individual becomes threat). spite fundamental differences between covariate that may not have any biological effect, measure behaviour animal, it common use as proxy for when hard (e.g. in species do exhibit distinguishable postures). However, relationship or reasons, but instead simply result from...
Raptors primarily use soaring-gliding flight which exploits thermals and ridge lifts over land to reduce energetic costs. However during migration, these birds often have cross water surfaces where thermal currents are weak; times, mainly flapping (powered) increases energy consumption mortality risk. As a result, some species evolved strategies the amount of time spent by taking extensive detours land. In this paper, we conducted meta-analysis water-crossing tendencies in Afro-Palearctic...
Abstract Honey bee foragers must supply their colony with a balance of pollen and nectar to sustain optimal development. Inter-individual behavioural variability among is observed in terms activity levels vs . collection, however the causes such variation are still open questions. Here we explored relationship between foraging performance honey bees ( Apis mellifera ) by using an automated behaviour monitoring system record mass on departing hive, trip duration, presence hind legs upon...
Abstract Animals have evolved foraging strategies to acquire blends of nutrients that maximize fitness traits. In social insects, nutrient regulation is complicated by the fact few individuals, foragers, must address divergent nutritional needs all colony members simultaneously, including other workers, reproductives, and brood. Here we used 3D geometry design examine how bumblebee workers regulate their collection 3 major macronutrients in presence absence We provided small colonies...
Variation in how individuals cope behaviourally and physiologically with stressors is widespread can have a significant impact on life-history traits fitness. Individual coping styles are characterised by differential behavioural adrenocortical reactivity to various challenges. As stress hormones affect the production of reactive chemical species antioxidant status, different may differ also oxidative status. Field studies wild mammalian populations few number none so far has simultaneously...
Workers of social insects, such as bees, ants and wasps, show some degree inter-individual variability in decision-making, learning memory. Whether these natural cognitive differences translate into distinct adaptive behavioural strategies is virtually unknown. Here we examined the movement patterns bumblebee foragers establishing routes between artificial flowers. We recorded all flower visitation sequences performed by 29 bees tested for 20 consecutive foraging bouts three experimental...
Pollutants can have severe detrimental effects on insects, even at sublethal doses, damaging developmental and cognitive processes involved in crucial behaviours. Agrochemicals been identified as important causes of pollinator declines, but the impacts other anthropogenic compounds, such metallic trace elements soils waters, received considerably less attention. Here, we exposed colonies European honey bee Apis mellifera to chronic field-realistic concentrations lead food demonstrated that...
Alpine plants are considered to be particularly vulnerable climate change and related extreme episodes, such as heat waves. Despite growing interest in the impact of waves on alpine plants, knowledge about their effects regeneration is still fragmentary. Recruitment from seeds will crucial for successful migration survival these species play a key role future adaptation change. In this study, we assessed impacts seed germination 53 high mountain Northern Apennines (Italy). The were exposed...
While many studies focus on how animals use public information, the dynamics of information spread and maintenance within groups, i.e. 'ecology information', have received little attention. Here we fruitflies trained to lay eggs specific substrates implement into groups containing both untrained individuals. We quantify inter-individual interactions then measure oviposition preference with behavioural tests. Untrained individuals increase their interactive approaches in presence individuals,...
Animals use a number of different mechanisms to acquire crucial information. During social encounters, animals can pass information from one another but, ideally, they would only that benefits survival and reproduction. Therefore, individuals need be able determine the value receive. One cue come behaviour other are already using Using previous extended dataset, we studied how individual decision-making is influenced by conspecifics in Drosophila melanogaster. We analysed uninformed flies...
Abstract Understanding how animal movements change across space and time is a fundamental question in ecology. While classical analyses of trajectories give insightful descriptors spatial patterns, satisfying method for assessing the temporal succession such patterns lacking. Network are increasingly used to capture properties complex simple graphical metrics. Here, building on this approach, we introduce that incorporates into movement network based sequences motifs. We illustrate our using...
Aggregation behaviour is the tendency for animals to group together, which may have important consequences on individual fitness. We used a combination of experimental and simulation approaches study how genetic variation social environment interact influence aggregation dynamics in Drosophila To do this, we two different natural lines that arise from polymorphism foraging gene (rovers sitters). placed groups flies heated arena. Flies could freely move towards one small, cooler refuge areas....
Matrilineal kin groups are common in social mammals and often exhibit cooperative behaviors. Social interactions such may have varying consequences on fitness depending the number of present. We used network analysis to study which factors (including individual spatial distribution, sex, age, kinship) affected patterns aggressive Columbian ground squirrels during important breeding period lactation. In addition, we studied how female reproduction fitness. Received aggressions lessened as...
The successful reintroduction and restocking of the European Bison demands a reliable knowledge biology this species. Yet little is known to date about bison, empirical data remains insufficient set up plan ensuring reintroduction, maintenance survival populations in habitats that have been largely modified by human activity. Studies ecology, social behaviour management bison are therefore crucial conservation species its cohabitation with humans. To meet these challenges, we focused on...
Parasites alter the physiology and behaviour of their hosts. In domestic honey bees, microsporidia Nosema ceranae induces energetic stress that impairs foragers, potentially leading to colony collapse. Whether this parasite similarly affects wild pollinators is little understood because low success rates experimental infection protocols. Here, we present a new approach for infecting bumblebees (Bombus terrestris) with controlled amounts N. by briefly exposing individual spores before feeding...
Central place foraging pollinators tend to develop multi-destination routes (traplines) exploit patchily distributed plant resources. While the formation of traplines by individual has been studied in detail, how populations foragers use resources a common area is an open question, difficult address experimentally. We explored conditions for emergence resource partitioning among traplining bees using agent-based models built from experimental data bumblebees on artificial flowers. In models,...
1. Pollinators, such as bees, face the complex challenge of efficiently exploiting patchily distributed floral resources across large landscapes. 2. In present study we consider utility spatial network statistics to analyse foraging patterns bees moving between feeding sites at various and temporal scales. 3. We explain how movement networks can be derived theoretically experimentally describe bee decisions. 4. illustrate this approach by analysing six datasets bumblebees honeybees in arrays...
Individual bees exhibit complex movement patterns to efficiently exploit small areas within larger plant populations. How such individual spatial behaviours scale up the collective level, when several foragers visit a common area, has remained challenging investigate, both because of low resolution field data and limited power statistical descriptors analyse them. To tackle these issues we video recorded all flower visits (N = 6205), every interaction on flowers 628), involving from...
