We deployed remote cameras at fresh wolf kills (<i>n</i> = 29) and built Bayesian generalized linear mixed models (GLMMs) to explore the use of fresh wolf-killed prey by sympatric wolves and wolverines.

Wolverines visited 100% of wolf kills in fall and winter, whereas only 18% in summer. We found that in winter, wolverines visited wolf kills 3.6 and 6.7 times more often than single wolves and wolf groups revisited their kills, and spent 10 and 25 times as much time at carcasses compared to single wolves and groups of wolves. Thus, wolverines played an important role in the depletion of wolf-killed prey, with potential effects on the scavenging behavior of other guild members.

Across three seasons, we explored the use of fresh wolf-killed prey by sympatric wolves and wolverines. Our findings reveal that wolves facilitate wolverines by providing scavenging opportunities, where biomass available from kills is influenced by wolves’ prey preference and group size.

Their modulatory potential on cognitive processes has been demonstrated in both vertebrates and invertebrates. Particularly interesting in this regard are social insects, due to their extensive use of pheromones to organise collective behaviour. Recruitment pheromones might be expected to encourage learning, but could also hinder learning due to a blocking effect, whereby the pheromone already partially predicts the reward, hindering further cues being associated with the reward. Here, we use free-running learning assays using realistic pheromone strength to test for a modulation effect on learning in the black garden ant <em>Lasius niger</em>.

The fact that associative learning does not seem to be influenced by recruitment pheromone in <em>L. niger</em> and reportedly the Argentine ant, while it is in honeybees, the possibly best-studied social insect species, is noteworthy.

We documented facultative kleptoparasitism in two similarly-sized raptors, the lesser kestrel (<i>Falco naumanni</i>) and the red-footed falcon (<i>Falco vespertinus</i>). These two species currently co-occur in Northern Italy due to recent range shifts influenced by climate and land-use changes. Multi-year focal observations revealed that single or multiple red-footed falcons were associated with 72% of foraging groups of lesser kestrels. Red-footed falcons initiated kleptoparasitic attacks on lesser kestrels in 46% of foraging group observations, with a success rate of 34%. Attacks were more likely when the prey capture rate (i.e. a proxy of foraging efficiency) of lesser kestrels was high. Red-footed falcons were more successful in stealing prey when the food items carried by lesser kestrels were larger, and kleptoparasitic attacks by groups of red-footed falcons had a higher success rate than attacks by singletons. Overall, we propose that such frequent kleptoparasitic events, which have never been previously documented in these two species, may have emerged as a consequence of their recently established co-occurrence. Kleptoparasitism could reduce the foraging efficiency and fitness of lesser kestrels, potentially leading to broader ecological consequences, such as population declines or range shifts.

However, a major challenge is to experimentally determine whether such manipulations confer an adaptive advantage to the parasite. Behavioral alterations in spiders attacked by ichneumonid wasps are characterized by the construction of modified webs. These modified webs can enhance the survival chances of the parasitoid by reducing mortality due to natural enemies and environmental factors during the pupal stage. Additionally, some modified webs offer extra protection by keeping a centrally attached leaf shelter, originally used by the spider as a refuge, where parasitoids can build their cocoon. In these webs, it is possible that web modifications are not critical for the survival of parasitoid pupae. We evaluated the hypothesis that modifications made by parasitized spiders in a web with leaf shelter do not improve the survival of the parasitoid and presented details of behavioral modifications induced by the wasp <i>Zatypota alborhombarta</i> (Ichneumonidae) in its host spider <i>Cryptachaea migrans</i> (Theridiidae). We observed that modified webs built by parasitized spiders had silk thread around the web shelter, reduced vertical lines, and an increase in forked distal ends of lines. However, these changes in the host web did not improve the survival of parasitoid pupae. Our results indicate that the benefits of host behavioral modification for the parasitoids may vary across different host species. In addition, we suggested that the effects of altered web designs may depend on specific host-created web features and environmental factors like predation pressure.</p><h3 data-test=\"abstract-sub-heading\">Significance statement</h3><p>Behavioral manipulations of hosts induced by parasites are often suggested as an adaptive trait, increasing the fitness of the parasitic organism.

Here, we demonstrate for the first time that behavioral modifications induced by Ichneumonidae wasps in a cobweb spider do not increase the survival of the parasitoids. We argue that the presence of shelters in these webs, used by parasitoids in their pupal stages, provides a safe environment for development, independent of other modifications.

To unravel whether sociality and communication systems co-evolve, research efforts have often targeted the links between social organisation and communicative repertoires. However, it is still unclear which social or interactional factors directly predict communicative complexity. To address this issue, we studied wild and zoo-housed immature orangutans of two species to assess the impact of the socio-ecological setting on the production of non-vocal signal repertoires. Specifically, we compared repertoire size, dyadic repertoire similarity, and number of social goals (i.e. observer’s estimate of the signaller’s intended interaction outcome) for communicative interactions with mothers versus other conspecifics, controlling for critical individual and environmental factors. In this small sample of immature orangutans, wild-captive contrasts were statistically significant only for other-directed repertoires, but not for mother-directed repertoires, and not for the number of social goals that immatures communicated towards. While the repertoires of individuals living in the same research setting were more similar than those living in contrasting settings, this difference was most pronounced for other-directed repertoires of the less socially tolerant orangutan species. These results suggest that the boosted interactional opportunities in captivity rather than mere differences in environmental affordances or communicative needs drive the wild-captive contrast in orangutan communicative repertoires. Overall, this fine-grained analysis of repertoires further underscores that not only a species’ social organisation but also the targeted audience may have a profound impact on communicative behaviour.</p> </span> <span> <h3>Significance statement</h3> <p>Navigating a dynamic social environment often requires flexible signal use. While it has repeatedly been shown that the social organisation and structure of species predict the complexity of their communication systems, the mechanisms underlying these relationships are largely unknown.

This contrast allows a direct test of how repertoires respond to the relevant difference in socio-ecological conditions.
