The response of plant species to environmental change, including climate, is based on phenotypic plasticity. Empirical research can help in understanding how invasive plants adapt to changing conditions for successful establishment. Our goal was to assess the effect of environment of origin and ecotypic variation on phenotypic response of native and invasive Phragmites australis using morphological and ecophysiological measurements. We established a common garden study using seeds collected from Southwest, Midwest, and Great Lakes regions...

Global temperature changes have emphasized the need to understand how species adapt to thermal stress across their ranges. Genetic mechanisms may contribute to variation in thermal tolerance, providing evidence for how organisms adapt to local environments. We determine physiological thermal limits and characterize genome-wide transcriptional changes at these limits in bumble bees using laboratory-reared Bombus vosnesenskii workers. We analyze bees reared from latitudinal (35.7–45.7°N) and altitudinal (7–2154 m) extremes of the species’ range to correlate...

Broom snakeweed (Gutierrezia sarothrae [Pursh] Britton & Rusby) is a native invasive species that is widely distributed across western North America. It is very competitive with other vegetation and can reduce or displace desirable grasses and forbs. Removal of snakeweed from rangelands can result in increased forage production of desirable plant species. The evaluation of new herbicides to determine their efficacy in controlling broom snakeweed assists in providing land managers with alternatives to control broom...

Physical and physiological performance traits are constrained by their energetic costs, potentiating trade-offs when competing demands of the environment (internal, external) impinge upon concurrent investment. For reptiles, the costs of responding to internal challenges (e.g. infection, injury) can impede coping with external challenges (e.g. predator avoidance, foraging), and vice versa. Whether phenotypic shifts in performance occur may depend on not only challenge type and energetic state, but also challenge severity and response priority. To address...

Statement of Benefit: Our multi-year, multi-season study of oxidized mercury measurements at a site that intercepts both boundary layer and free tropospheric air masses will address major areas of uncertainty in atmospheric mercury chemistry, namely the characterization of the governing oxidation mechanism(s) in a continental atmosphere.

This investigation examined the effects of a self-study package on three early childhood special education teachers' use of coincidental teaching with preschool children with, or at risk for, disabilities. The results of this investigation showed that all teachers performed better on a posttest than a pretest measure for knowledge of coincidental teaching. Teachers were also able to complete a series of written assignments pertaining to coincidental teaching. Increases in coincidental teaching knowledge, however, were not...

This is the call for papers for the special issue on bird damage.

One Health has become more important in recent years because interactions between people, animals, plants, and our environment have dramatically changed. This Back Page article discusses One Health during the COVID-19 pandemic.
