Predation risk drives long-term shifts in migratory behavior and demography in a large herbivore population
<p>Migration is an adaptive life-history strategy that helps individuals across taxa maximize fitness by obtaining forage and avoiding predation risk. The mechanisms driving migratory changes are poorly understood, and links between migratory behavior, space use, and demographic consequences are rare. Here, we use a nearly 20-year record of individual-based monitoring of elk (<em>Cervus canadensis</em>) to test hypotheses for changing patterns of migration in a large herbivore, elk (<em>Cervus canadensis</em>), in and adjacent to a large protected area in Banff National Park (BNP), Canada. We test whether bottom-up (forage quality) or top-down (predation risk) factors explained trends in i) the proportion of individuals using 5 different migratory tactics, ii) differences in survival rates of migratory tactics during migration and whilst on summer ranges, iii) cause-specific mortality by wolves and grizzly bears, and iv) population abundance. We found dramatic shifts in migration consistent with behavioral plasticity in individual choice of annual migratory routes. Shifts were inconsistent with exposure to the bottom-up benefits of migration. Instead, exposure to landscape gradients in predation risk caused by exploitation outside the protected area drove migratory shifts. Carnivore exploitation outside the protected area led to higher survival rates for female elk remaining resident or migrating outside the protected area. Cause-specific mortality aligned with exposure to predation risk along migratory routes and summer ranges. Wolf predation risk was higher on migratory routes than summer ranges of montane-migrant tactics, but wolf predation risk traded-off with heightened risk from grizzly bears on summer ranges. A novel eastern migrant tactic emerged following a large forest fire that enhanced forage in an area with lower predation risk outside of the protected area. The changes in migratory behavior translated to population abundance, where abundance of the montane-migratory tactics declined over time. The presence of diverse migratory life histories maintained a higher total population abundance than would have been the case with one migratory tactic in the population. Our study demonstrates the complex ways in which migratory populations change over time through behavioral plasticity and associated demographic consequences because of individuals balancing predation risk and forage trade-offs.</p>
Signatures of adaptive decreased virulence of deformed wing virus in an isolated population of wild honey bees (Apis mellifera)
<p>Understanding the ecological and evolutionary processes that drive host-pathogen interactions is critical for combating epidemics and conserving species. The <em>Varroa</em> <em>destructor</em> mite and deformed wing virus (DWV) are two synergistic threats to Western honey bee (<em>Apis</em> <em>mellifera</em>) populations across the globe. Distinct honey bee populations have been found to self-sustain despite <em>Varroa</em> infestations, including colonies within the Arnot Forest outside Ithaca, NY, USA. We hypothesized that in these bee populations, DWV has been selected to produce an avirulent infection phenotype, allowing for the persistence of both host and disease-causing agents. To investigate this, we assessed the titer of viruses in bees from the Arnot Forest and managed apiaries, and assessed genomic variation and virulence differences between DWV isolates. Across groups, we found viral abundance was similar, but DWV genotypes were distinct. We also found that infections with isolates from the Arnot Forest resulted in higher survival and lower rates of symptomatic deformed wings, compared to analogous isolates from managed colonies, providing preliminary evidence to support the hypothesis of adaptive decreased viral virulence. Overall, this multi-level investigation of virus genotype and phenotype across different contexts reveals critical insight into global bee health and the ecological and evolutionary processes driving host-pathogen interactions.</p>
Figure 5 in Genetic integrity of the European grayling (Thymallus thymallus) populations within the Vienne River drainage basin after five decades of stockings
Figure 5 - Results of the Structure analysis (Q-values) for 8 loci (A) and 10 loci (B). Colours represent the different "k" units chosen using the approach of Evanno et al. (2005). Population names are shown on the x-axis, and Q-values (contribution or assignment from each k partition) are shown on the Y-axis. For 8 loci, k = 8, and for 10 loci k = 11.

All new haplotypes use the simple abbreviation "Ht" with a serial number reflecting the order in which they were first found in our data. The small black dots indicate substitutional steps whereas the small red dots represent multifurcating nodes. The following haplotypes and corresponding clade names stem from Weiss et al. (2002). "Danube drainage (Northern Alps)": Da1, Da2, Da4, Da11; "Mixed Central Europe": Rh1, Rh4, Rh6 all first reported from the Rhone basin; "Mixed Central Europe": At14, At15 both frequent and widespread in the Rhine basin; "Scandinavia": At6 reported from Finland; and AT1 first reported from the Loire River.
