Exploration speed in captivity predicts foraging tactics and diet in free-living red knots
<p>Variation in foraging tactics and diet are usually attributed to differences in morphology, experience, and prey availability. Recently, consistent individual differences in behaviour (personality) have been shown to be associated with foraging strategies. Bolder or more exploratory individuals are predicted to have a faster pace-of-life and offset the costs of moving more or in risky areas, with higher energetic gains by encountering profitable foraging opportunities and prey. However, the relationship between personality, foraging, and diet is poorly understood.</p> <p>We investigated how exploratory behaviour in red knots (<em>Calidris canutus</em><i>) </i>is associated with foraging tactics and diet by combining laboratory experiments, field observations, and stable isotope analysis. First, we developed a mobile experimental arena to measure exploration speed in controlled settings. We validated the method by repeated testing of individuals over time and contexts. This setup allowed us to measure exploratory personality at the field site, eliminating the need to bring birds into captivity for long periods of time. After releasing birds within days of their capture, we asked whether exploration speed was associated with differences in foraging tactics and diet in the wild.</p> <p>We found that tactile foraging red knots mainly caught hard-shelled prey that are buried in the sediment, whereas visual foraging knots only captured soft preys located close to or on the surface. We also found that faster explorers showed a higher percentage of visual foraging than slower explorers. By contrast, morphology (bill length and gizzard size) had no significant effect on foraging tactics. Diet analysis based on δ15N and δ13C stable isotope values of plasma and red blood cells confirmed our field observations with slower explorers mainly consumed hard-shelled prey while faster explorers consumed more soft than hard-shelled prey.</p> <p>Our results show that foraging tactics and diet are associated with a personality trait, independent of morphological differences. We discuss how consistent behaviour might develop early in life through positive feedbacks between foraging tactics, prey type, and foraging efficiency.</p>
Distribution. Balabac, Ramos, and Bugsuk Is, Palawan region, Phillipines. In the late 1990s, a small stock of eight Balabac Chevrotains escaped from their enclosures on Calauit Island, a small island off the coast of Busuanga Island, north of Palawan, where the species had been maintained and bred since 1982. These animals were reported to have increased to at least 21 free-living individuals by 2006. Apparently the species was also introduced to the larger island of Palawan. No recent records confirm that it is still extant there, although unconfirmed reports suggest that it may survive in southern Palawan. in Tragulidae

Data from: Within-trio tests provide little support for post-copulatory selection on MHC haplotypes in a free-living population
<p>Sexual selection has been proposed as a force that could maintain the diversity of major histocompatibility complex (MHC) genes in vertebrates. Potential selective mechanisms can be divided into pre-copulatory and post-copulatory, and in both cases the evidence for occurrence is mixed, especially in natural populations. In this study, we used a large number of parent-offspring trios that were diplotyped for MHC class II genes in a wild population of Soay sheep (<i>Ovis aries</i>) to examine whether there was within-trio post-copulatory selection on MHC genes at both the haplotype and diplotype levels. We found there was transmission ratio distortion of one the eight MHC class II haplotype (E) which was transmitted less than expected by fathers, and transmission ratio distortion of another haplotype (A) which was transmitted more than expected by chance to male offspring. However, in both cases these deviations were not significant after correction for multiple tests. In addition, we did not find any evidence of post-copulatory selection on diplotype level. These results imply given known parents, there is no strong post-copulatory selection on MHC genes in this population.</p>
