Gilroy's Black Atlantic diaspora: climate displacement and rights‐bearing beyond the nation

open access: yesNations and Nationalism, EarlyView.
Abstract Nationalism studies have only recently started to grapple with the Anthropocene as a foundational shift for the discipline. One of the effects of climate change is the forced displacement of large populations, and if access to rights cannot be ensured outside the structures of territorial sovereignty, this migration could easily translate into

Defining the pyro‐thermal niche: do seed traits, ecosystem type and phylogeny influence thermal thresholds in seeds with physical dormancy?

open access: yesNew Phytologist, EarlyView.
Summary Seeds are a key pathway for plant population recovery following disturbance. To prevent germination during unsuitable conditions, most species produce dormant seeds. In fire‐prone regions, physical dormancy (PY) enables seeds to germinate after fire. The pyro‐thermal niche, incorporating temperature effects into seed dormancy and mortality, has

Leaf Turgor Loss Does Not Coincide With Cell Plasmolysis in Drought‐Tolerant Chaparral Species

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT The water potential at which leaf cells lose turgor (ΨTLP) is a useful predictor of whole‐plant drought tolerance and biome wetness. However, many plants can achieve water potential values below ΨTLP and recover, raising questions about the physiological processes that occur below ΨTLP.

Polarization on social media: Comparing the dynamics of interaction networks and language‐based opinion distributions

open access: yesPolitical Psychology, EarlyView.
Abstract When people share information and converse on social media, they create “echo chambers” through preferential attachment to like‐minded people and opinions they already support. A great deal of research uses interactional ties between people—created by retweeting and following—to identify and study polarization in social networks.

“It's all about trust!” a multilevel model of the effect of servant leadership on firefighters' group task performance, adaptivity and emotional exhaustion

open access: yesPublic Administration Review, EarlyView.
Abstract How and why does servant leaders' behavior influence both performance (individual and collective) and emotional exhaustion within dynamic and extreme environments such as those of firefighters? We develop and test a multilevel model that integrates the principles of servant leadership with social exchange theory to explore how servant ...
