Genomic analysis reveals a polygenic architecture of antler morphology in wild red deer (Cervus elaphus)
<p>Sexually-selected traits show large variation and rapid evolution across the animal kingdom, yet genetic variation often persists within populations despite apparent directional selection. A key step in solving this long-standing paradox is to determine the genetic architecture of sexually-selected traits to understand evolutionary drivers and constraints at the genomic level. Antlers are a form of sexual weaponry in male red deer. On the island of Rum, Scotland, males with larger antlers have increased breeding success, yet there has been no evidence of any response to selection at the genetic level. To try and understand the mechanisms underlying this observation, we investigate the genetic architecture of ten antler traits and their principal components using genomic data from >38,000 SNPs. We estimate the heritabilities and genetic correlations of the antler traits using a genomic relatedness approach. We then use genome-wide association and haplotype-based regional heritability to identify regions of the genome underlying antler morphology, and an Empirical Bayes approach to estimate the underlying distributions of allele effect sizes. We show that antler morphology is highly repeatable over an individual's lifetime, heritable, and has a polygenic architecture, and that almost all antler traits are positively genetically correlated with some loci identified as having pleiotropic effects. Our findings suggest that a large mutational target and genetic covariances among antler traits, in part maintained by pleiotropy, are likely to contribute to the maintenance of genetic variation in antler morphology in this population.</p>

Dust deposition in Red Sea corals
<p>Climate change-related increase in seawater temperature has become a leading cause of coral bleaching and mortality. However, corals from the northern Red Sea show high thermal tolerance and no recorded massive bleaching event. This specific region is frequently subjected to intense dust storms, coming from the surrounding arid deserts, which are expected to increase in frequency and intensity in the future. The aerial dust deposition supplies essential bioelements to the water column. Here, we investigated the effect of dust deposition on the physiology of a Red Sea coral, <em>Stylophora pistillata</em>. We measured the modifications in coral and Symbiodiniaceae metallome (cellular metal content), as well as the changes in photosynthesis and oxidative stress status of colonies exposed during few weeks to dust deposition. Our results show that 1 mg L<sup>-1</sup> of dust supplied nanomolar amounts of nitrate and other essential bioelements, such as iron, manganese, zinc, and copper, rapidly assimilated by the symbionts. At 25 °C, metal bioaccumulation enhanced the chlorophyll concentration and photosynthesis of dust-exposed corals compared to control corals. These results suggest that primary production was limited by metal availability in seawater. A 5 °C increase in seawater temperature enhanced iron assimilation in both control and dust-enriched corals. Temperature rise increased the photosynthesis of control corals only, dust-exposed ones having already reached maximal photosynthesis rates at 25 °C. Finally, we observed a combined effect of temperature and bioelement concentration on the assimilation of molybdenum, cadmium, manganese, and copper, which were in higher concentrations in symbionts of dust-exposed corals maintained at 30 °C. All together these observations highlight the importance of dust deposition in the supply of essential bioelements, such as iron, to corals and its role in sustaining coral productivity in Red Sea reefs.</p>
Giant sengi or elephant-shrew (Rhynchocyon species) interactions with Red-Capped Robin-Chat (Cossypha natalensis) and White-Chested Alethe (Chamaetylas fuelleborni) in Tanzania
<p>Using camera traps and direct observations, we recorded interactions between three species of giant sengi (<em>Rhynchocyon sp.</em>) and two insectivorous bird species from five forests in Tanzania. In all instances, the birds closely followed the giant sengis who were moving and foraging in the leaf litter. Given the two bird species are insectivorous and follow ant swarms to obtain flushed prey, these interactions suggest that following the sengi represents an adaptive foraging strategy. Our observations indicate that these behaviors and associations may be more pervasive than previously thought.</p>

Spatial variation in antler investment of Apennine red deer
<p>Heterogeneity in resource availability and quality can trigger spatial patterns in the expression of sexually selected traits such as body mass and weaponry. While relationships between habitat features and phenotypic quality are well established at a broad geographical scale, information is scanty on spatial patterns at a finer, intra-population scale. We used data collected on 1965 male red deer Cervus elaphus over 20 years from a non-migratory population living on two sides of a mountainous ridge with substantial differences in land cover and habitat quality but similar climate and population density. We investigate spatial patterns in (i) body mass, (ii) antler mass, (iii) antler investment. We also tested for site- and age-specific patterns in allometric relationship between body mass and antler mass. Statistically significant fine-scale spatial variations in body mass, antler mass and, to a lesser extent, antler allocation matched spatial differences in land cover. All three traits were greater in the northern slope, characterized by higher habitat heterogeneity and greater availability of open habitats, than in the southern slope. Moreover, the allometric relationship between body mass and antler mass differed among age classes, in a pattern that was consistent between the two mountain slopes. Our results support the occurrence of spatial patterns in the expression of individual attributes also at a fine, intra-population scale. Our findings emphasize the role of environmental heterogeneity in shaping spatial variations of key life-history traits, with potential consequences for reproductive success.</p>

Bimodal acoustic calls used in mate-choice and aggression by red-eyed treefrogs
<p>Dataset in support of the manuscript entitled: Beyond sound: Bimodal acoustic calls used in mate-choice and aggression by red-eyed treefrogs.</p> <p>Included are results from bimodal, sound and vibration, playback trials with male and female red-eyed treefrogs (Agalychnis callidryas). Listed are trial type, whether the animal, if female, was collected in amplexus, and measures of its response to playback. These data may be reused freely.</p> <p>A description of the study follows.</p> <p>Airborne sound signals function as key mediators of mate-choice, aggression, and other social interactions in a wide range of vertebrate and invertebrate animals. Calling animals produce more than sound, however. When displaying on or near a solid substrate, such as vegetation or soil, they also unavoidably excite substrate vibrations due to the physics of sound production and of acoustic propagation, and these vibrations can propagate to receivers. Despite their near ubiquity, these vibrational signal components have received very little research attention, and in vertebrates it is completely unknown whether they are relevant to mate-choice, an important driver of evolutionary divergence. Here we show that female red-eyed treefrogs are more than twice as likely to choose a male mating call when airborne sound is paired with its corresponding substrate vibrations. Furthermore, males of the same species are more aggressive towards and display a greater range of aggressive behaviors in response to bimodal (sound and vibration) versus unimodal (sound or vibration alone) calls. In aggressive contexts, at least, air- and substrate-borne signal components function non-redundantly. These results are a clear demonstration that vibrations produced by a calling animal can function together with airborne sound to markedly enhance the function of a signal. If this phenomenon proves widespread, this finding has the potential to substantially influence our understanding of the function and evolution of acoustic signals.</p>
