Data from: Common evolutionary trends underlie the four-bar linkage systems of sunfish and mantis shrimpYinan Hu, Nathan Nelson-Maney, Philip S.L. Anderson & Philip S. L. Anderson
Comparative biomechanics offers an opportunity to explore the evolution of disparate biological systems that share common underlying mechanics. Four-bar linkage modelling has been applied to various biological systems such as fish jaws and crustacean appendages to explore the relationship between biomechanics and evolutionary diversification. Mechanical sensitivity states that the functional output of a mechanical system will show differential sensitivity to changes in specific morphological components. We document similar patterns of mechanical sensitivity in two disparate...
Data from: Pythons, parasites and pests: anthropogenic impacts on Sarcocystis (Sarcocystidae) transmission in a multi-host systemAnne Devan-Song, Sonja Luz, Abraham Mathew, Mary-Ruth Low & David P. Bickford
Parasites are essential components of ecosystems and can be instrumental in maintaining host diversity and populations; however, their role in trophic interactions has often been overlooked. Three apicomplexan parasite species of Sarcocystis (S. singaporensis, S. zamani, and S. villivillosi) use the reticulated python as their definitive hosts and several species within the Rattus genus as intermediate hosts, and they form a system useful for studying interactions between host–parasite and predator–prey relationships, as well as anthropogenic...
1. Although many vector-borne plant pathogens can alter vector behavior to the pathogen's benefit, how plants might counter such manipulation is unknown. 2. In the Tomato yellow leaf curl virus (‘TYLCV’)-Bemisia tabaci-tomato interaction, TYLCV-mediated changes in Bemisia feeding improves viral uptake and transmission. We tested how jasmonic acid (‘JA’), a central regulator of plant anti-herbivore defenses, affected the ability of TYLCV to (A) manipulate Bemisia behavior; and (B) infect plants. 3. Viruliferous Bemisia fed much...
Data from: Satellite telemetry reveals higher fishing mortality rates than previously estimated, suggesting overfishing of an apex marine predatorMichael E. Byrne, Enric Cortés, Jeremy J. Vaudo, Guy C. McN. Harvey, Mark Sampson, Bradley M. Wetherbee & Mahmood Shivji
Overfishing is a primary cause of population declines for many shark species of conservation concern. However, means of obtaining information on fishery interactions and mortality, necessary for the development of successful conservation strategies, are often fisheries-dependent and of questionable quality for many species of commercially exploited pelagic sharks. We used satellite telemetry as a fisheries-independent tool to document fisheries interactions, and quantify fishing mortality of the highly migratory shortfin mako shark (Isurus oxyrinchus) in the...
Data from: Individual and non-additive effects of exotic sap-feeders on root functional and mycorrhizal traits of a shared conifer hostRobert N. Schaeffer, Claire M. Wilson, Laura Radville, Mauri Barrett, Elizabeth Whitney, Sofia Roitman, Esther R. Miller, Benjamin E. Wolfe, Carol S. Thornber, Colin M. Orians & Evan L. Preisser
Forest pests drive tree mortality through disruption of functional traits linked to nutrient acquisition, growth, and reproduction. The impacts of attack by individual or multiple aboveground herbivores on root functional traits critical to tree health have received little attention. This is especially true for exotic herbivores, organisms often found in disturbed forests. We excavated whole-root systems from eastern hemlock (Tsuga canadensis) individuals experimentally infested with hemlock woolly adelgid (HWA: Adelges tsugae) and elongate hemlock scale...
Aim We examine the influence of fluctuating sea levels in a land-bridge archipelago on the apportioning of intraspecific genetic diversity and divergence in the widespread Puerto Rican crested anole (Anolis cristatellus). We compare three alternative scenarios for genetic diversification in an archipelagic species that contrast the relative influences of periodic isolation versus island connectedness driven by fluctuating sea levels. Our approach combines information from geography and population genetics to assess the influence of island size,...
