Effects of social structure and management on risk of disease establishment in wild pigs
<p>1. Contact heterogeneity among hosts determines invasion and spreading dynamics of infectious disease, thus its characterization is essential for identifying effective disease control strategies. Yet, little is known about the factors shaping contact networks in many wildlife species and how wildlife management actions might affect contact networks.</p> <p>2. Wild pigs in North America are an invasive, socially-structured species that pose a health concern for domestic swine given their ability to transmit numerous devastating diseases such as African swine fever (ASF). Using proximity loggers and GPS data from 48 wild pigs in Florida and South Carolina, USA, we employed a probabilistic framework to estimate weighted contact networks. We determined the effects of sex, social group, and spatial distribution (monthly home range overlap and distance) on wild pig contact. We also estimated the impacts of management-induced perturbations on contact and inferred their effects on ASF establishment in wild pigs with simulation.</p> <p>3. Social group membership was the primary factor influencing contacts. Between-group contacts depended primarily on space use characteristics, with fewer contacts among groups separated by >2 km and no contacts among groups >4 km apart within a month.</p> <p>4. Modeling ASF dynamics on the contact network demonstrated that indirect contacts resulting from baiting (a typical method of attracting wild pigs or game species to a site to enhance recreational hunting) increased the risk of disease establishment by ~33% relative to direct contact. Low-intensity population reduction (<5.9% of the population) had no detectable impact on contact structure but reduced predicted ASF establishment risk relative to no population reduction.</p> <p>5. We demonstrate an approach for understanding the relative role of spatial, social, and individual-level characteristics in shaping contact networks and predicting their effects on disease establishment risk, thus providing insight for optimizing disease control in spatially- and socially-structured wildlife species.</p>
Wolbachia infection in wild mosquitoes (Diptera: Culicidae): Implications for transmission modes and host-endosymbiont associations in Singapore
<p><strong>Background: </strong></p> <p><em>Wolbachia</em> are intracellular bacterial endosymbionts found in most insect lineages. In mosquitoes, the influence of these endosymbionts on host reproduction and arboviral transmission has spurred numerous studies aimed at using <em>Wolbachia</em> infection as a vector control technique. However, there are several knowledge gaps in the literature and little is known about natural <em>Wolbachia</em> infection across species, their transmission modes, or associations between various <em>Wolbachia</em> lineages and their hosts. This study aims to address these gaps by exploring mosquito-<em>Wolbachia</em> associations and their evolutionary implications.</p> <p><strong>Methods:</strong></p> <p>We conducted tissue-specific polymerase chain reaction screening for <em>Wolbachia</em> infection in the leg, gut and reproductive tissues of wild mosquitoes from Singapore using the <em>Wolbachia</em> surface protein gene (<em>wsp</em>) molecular marker. Mosquito-<em>Wolbachia</em> associations were explored using three methods— tanglegram, distance-based, and event-based methods—and by inferred instances of vertical transmission and host shifts.</p> <p><strong>Results:</strong></p> <p>Adult mosquitoes (271 specimens) representing 14 genera and 40 species were screened for <em>Wolbachia</em>. Overall, 21 species (51.2%) were found positive for <em>Wolbachia</em>, including five in the genus <em>Aedes</em> and five in the genus <em>Culex</em>. To our knowledge, <em>Wolbachia</em> infections have not been previously reported in seven of these 21 species: <em>Aedes nr. fumidus, Aedes annandalei, Uranotaenia obscura, Uranotaenia trilineata, Verrallina butleri, Verrallina </em>sp.<em> and Zeugnomyia gracilis</em>. <em>Wolbachia</em> were predominantly detected in the reproductive tissues, which is an indication of vertical transmission. However, <em>Wolbachia</em> infection rates varied widely within a mosquito host species. There was no clear signal of cophylogeny between the mosquito hosts and the 12 putative <em>Wolbachia</em> strains observed in this study. Host shift events were also observed.</p> <p><strong>Conclusions:</strong></p> <p>Our results suggest that the mosquito-<em>Wolbachia</em> relationship is complex and that combinations of transmission modes and multiple evolutionary events likely explain the observed distribution of <em>Wolbachia</em> diversity across mosquito hosts. These findings have implications for a better understanding of the diversity and ecology of <em>Wolbachia</em> and for their utility as biocontrol agents.</p>

Plant species fed on by wild ring-tailed lemurs (Lemur catta) at nine sites
<p>A key aspect of a primate's ecology is its food source – the very nature of which is spatially and seasonally dependent, and may be affected by anthropic pressures. One of the most endangered, yet best-studied, strepsirrhine primates is the ring-tailed lemur (<i>Lemur catta</i>) – a species that has experienced significant human-induced habitat loss over many decades. To help understand feeding variability across time and space, I present a literature review of plant species (and parts) fed on by ring-tailed lemurs at nine sites in Madagascar: Ambatotsirongorongo, Andringitra Massif, Anja Reserve, Antserananomby, Berenty Reserve, Bezà Mahafaly Special Reserve, Cap Sainte-Marie, Tsaranoro Valley Forest, and Tsimanampetsotsa National Park. I gathered literature using keyword searches on Google Scholar (<a href="https://scholar.google.com/">https://scholar.google.com/</a>), and verified scientific names using the "Catalogue of the Plants of Madagascar" (<a href="http://legacy.tropicos.org/Project/Madagascar">http://legacy.tropicos.org/Project/Madagascar</a>). From 24 studies, I identify 221 genera and 241 species of consumed plants, with 92 genera and 70 species consumed at two or more sites. Based on the available distribution data, 63% of species are endemic and 22% native. Sixty-seven plants are known only by Malagasy common names and excluded from analyses. When authors identify the plant tissue consumed, 52% of species in the diet are represented by a single tissue type, typically leaves (mature and immature) or fruit (ripe or unripe). This review highlights the importance of studying multiple populations when creating dietary summaries of species and should prove valuable to those exploring ecological trends and habitat use by ring-tailed lemurs.</p>
Co-infection best predicts respiratory viral infection in a wild host
<p>1) The dynamics of directly transmitted pathogens in natural populations are likely to result from the combined effects of host traits, pathogen biology and interactions among pathogens within a host. Discovering how these factors work in concert to shape variation in pathogen dynamics in natural host – multi‐pathogen systems is fundamental to understanding population health.</p> <p>2) Here, we describe temporal variation in incidence and then elucidate the effect of hosts trait, season, and pathogen co‐occurrence on host infection risk using one of the most comprehensive studies of co‐infection in a wild population: a suite of seven directly‐transmitted, viral and bacterial, respiratory infections from a four‐year study of 200 free‐ranging African buffalo (<i>Syncerus caffer</i>).</p> <p>3) Incidence of upper respiratory infections was common throughout the study – five out of the seven pathogens appeared to be consistently circulating throughout our study population. One pathogen exhibited clear outbreak dynamics in our final study year and another was rarely detected.</p> <p>4) Co‐infection was also common in this system. The strongest indicator of pathogen occurrence for respiratory viruses was, in fact, the presence of other viral respiratory infections. Host traits had minimal effects on odds of pathogen occurrence but did modify pathogen‐pathogen associations. In contrast, only season predicted bacterial pathogen occurrence.</p> <p>5) Though a combination of environmental, behavioral, and physiological factors work together to shape disease dynamics, we found pathogen associations best determined infection risk. Our study demonstrates that, in absence of very fine‐scale data, the intricate changes among these factors are best represented by co‐infection.</p>
Eco-genetic additivity of diploids in allopolyploid wild wheats
Underpinnings of the distribution of allopolyploid species (hybrids with duplicated genome) along spatial and ecological gradients are elusive. As allopolyploid speciation combines the range of genetic and ecological characteristics of divergent diploids, allopolyploids initially show their additivity and are predicted to evolve differentiated ecological niches to establish in face of their competition. Here, we use four diploid wild wheats that differentially combined into four independent allopolyploid species to test for such additivity and assess the impact of ecological constraints on species ranges. Divergent genetic variation from diploids being fixed in heterozygote allopolyploids supports their genetic additivity. Spatial integration of comparative phylogeography and modeling of climatic niches supports ecological additivity of locally adapted diploid progenitors into allopolyploid species which subsequently colonized wide ranges. Allopolyploids fill suitable range to a larger extent than diploids and conservative evolution following the combination of divergent species appears to support their expansion under environmental changes.

Diet variation driven by color vision phenotype in wild capuchin monkeys
<p>The polymorphic color vision of platyrrhine monkeys is a fascinating example of balancing selection acting on multiple genetic and phenotypic morphs. Yet, the mechanism of natural selection maintaining this variation remains elusive. Past research has demonstrated task-specific foraging advantages to dichromatic (two-opsin vision, red-green colorblind) and trichromatic (three-opsin vision, human "normal") monkeys, raising the potential for dietary niche differentiation. We ask whether color vision type influences diet variation in a population of wild, white-faced capuchins (<i>Cebus imitator</i>) in Costa Rica. To assess this, we record food intake during simultaneous focal follows of adult female dichromats and trichromats, and classify the conspicuity of diet items in capuchin visual space. We assess the degree of dietary and nutritional niche overlap during periods of high and low fruit abundance using nutritional geometry and Pianka's index. We find that in months of high fruit abundance, trichromats have higher intake of conspicuously-colored fruits, while dichromats have higher intake of camouflaged invertebrates, resulting in lower niche overlap. These differences disappear in months of low habitat-wide fruit abundance, a time when overall dietary breadth collapses. Our results support the hypothesis that niche differentiation in diet contributes to maintaining color vision variation without compromising species-specific nutritional intake.</p>
Testing the niche differentiation hypothesis in wild capuchin monkeys with polymorphic color vision
<p>The polymorphic color vision system of most North, Central, and South American monkeys is a textbook case of balancing selection, yet the mechanism behind it is poorly understood. Previous work has established task-specific foraging advantages to different color vision phenotypes: dichromats (red-green colorblind) are more efficient foraging for invertebrates, while trichromats (color "normal" relative to humans) are more efficient foraging for "reddish" ripe fruit, suggesting that niche differentiation may underlie the maintenance of color vision variation. We explore a prediction of the niche differentiation hypothesis by asking whether dichromatic and trichromatic capuchin monkeys (<i>Cebus imitator</i>) diverge in their foraging activity budget, specifically testing whether dichromats forage more frequently for invertebrates and trichromats forage more frequently for "reddish" ripe fruit. To assess this, we analyze a large dataset of behavioral scan samples (n = 21,984) from 48 wild adult female capuchins of known color vision genotype, dominance rank and reproductive status, together with models of food conspicuity. We find no significant differences between dichromats and trichromats in the frequency of scans spent foraging for different food types but do find that nursing females forage less overall than cycling females. Our results suggest that the potential for color vision-based niche differentiation in foraging time may be curtailed by the energetic requirements of reproduction, behavioral synchrony caused by group-living, and/or individual preferences. While niche differentiation in activity budgets by color vision type is not apparent, fine-scale niche differentiation may be occurring. This research enhances our understanding of the evolutionary processes maintaining sensory polymorphisms.</p>
