Bacterial Genomics Reveal the Complex Epidemiology of an Emerging Pathogen in Arctic and Boreal Ungulates
Northern ecosystems are currently experiencing unprecedented ecological change, largely driven by a rapidly changing climate. Pathogen range expansion, and emergence and altered patterns of infectious disease, are increasingly reported in wildlife at high latitudes. Understanding the causes and consequences of shifting pathogen diversity and host-pathogen interactions in these ecosystems is imp...
متن کاملComparative genomics of rhizobia nodulating soybean suggests extensive recruitment of lineage-specific genes in adaptations.
The rhizobium-legume symbiosis has been widely studied as the model of mutualistic evolution and the essential component of sustainable agriculture. Extensive genetic and recent genomic studies have led to the hypothesis that many distinct strategies, regardless of rhizobial phylogeny, contributed to the varied rhizobium-legume symbiosis. We sequenced 26 genomes of Sinorhizobium and Bradyrhizob...
متن کاملPhysiological adaptation in savanna ungulates.
Savannas lie between the equatorial rain forests and the semi-deserts of the southern continents. From the herbivore’s viewpoint, the savanna environment is characterized by a mixture of herbaceous and woody vegetation, varying in quantity and growth stage according to the seasonal cycle of rainfall. C4 grasses (i.e. those with the C4 photosynthetic pathway) dominate the herbaceous layer, which...
متن کاملPatterns of reproductive effort in male ungulates
In ungulates, males and females have contrasting life histories, as usually only the females raise the young. How reproductive effort in males varies with individual level and population level characteristics has received little attention in the literature. Using published information on direct (weight loss during the rut) and indirect (rutrelated changes in activity budgets, fighting frequency...
متن کاملModification of Ecosystems by Ungulates
Ecosystem ecologists traditionally have focused their attention on direct interactions among species, particularly those interactions that control flows of energy and materials among trophic levels. Emerging evidence suggests that indirect interactions may be more important than direct ones in determining ecosystem patterns and processes. Here I review indirect effects of ungulates on nutrient ...
