Saussurea × media (Asteraceae), a new natural hybrid between S. parviflora and S. controversa

Nordic Journal of Botany, EarlyView.
Saussurea × media Yusupovsky and E.Pjak (Asteraceae), a new nothospecies from the Altai‐Sayan Mountains, is described and illustrated. In this study, we sequenced the internal transcribed spacer of nuclear ribosomal DNA and the chloroplast intergenic spacers rsp16‐trnQ and ycf4‐cemA to verify the hypothesis of hybridization between Saussurea parviflora

Mechanisms and impacts of future plant invasions: research agendas and management needs under disruptive social‐ecological change scenarios

Oikos, EarlyView.
No‐analogue futures are characteristic of the Anthropocene, but how global change, and societies' responses, will affect plant invasions remains unclear. Conducting research now to address future needs is crucial for guiding invasion management and policy.

Nonlinear interactive effects of temperature and soil moisture on plant biomass and carbon fluxes

Oikos, EarlyView.
Climate warming is affecting plant growth and CO2 fluxes in high‐latitude ecosystems. However, soil moisture – and how it responds to warming – can alter the shape of the relationship between temperature and both plant performance and ecosystem processes. We conducted a microcosm experiment to test the interactive effects of temperature, soil moisture,

The interacting effects of precipitation and microhabitat on non‐native seed predation are contingent on temporal dynamics

Oikos, EarlyView.
Understanding how different drivers of global change interact to shape ecological processes remains a major challenge in ecology. Climate change is reshuffling the interactions that structure communities, with major implications for biological invasions.

Competition and soil conditions limit the growth of High Arctic non‐native plants

Oikos, EarlyView.
Non‐native vascular plant species in the High Arctic are currently restricted mainly to settlements and other anthropogenically disturbed areas. The reasons for this remain unclear, but climate or dispersal do not appear to be the main limiting factors. Instead, biotic interactions combined with soil conditions may play important roles.

Ecosystem engineers and functional dominance: when species loss matters for ecosystem function

Oikos, EarlyView.
Understanding when and why species loss affects community function in natural communities remains an open question in ecology. Recent cross‐system analyses have shown that functional dominance is associated with whether species loss matters: in communities dominated by few high‐performing species, lost species contribute little to function.

The Mexico City Policy in US Development Policy and Its Backlash‐Frontlash‐Logic

Public Administration and Development, EarlyView.
ABSTRACT The Mexico City Policy provides for the discontinuation of U.S. government funding for foreign non‐governmental organizations (NGOs) that provide legal abortion services. While Republican administrations have repeatedly pushed for the introduction of the Mexico City Policy after their re‐election, those regulations have been rescinded by ...
