Interactions between maternal provisioning and natural selection on seed mass fluctuate across heat waves

American Journal of Botany, EarlyView.
Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

Drought Spatial Extent and Dependence Increase During Drought Propagation From the Atmosphere to the Hydrosphere

Geophysical Research Letters
As droughts propagate both in time and space, their impacts increase because of changes in drought properties. Because temporal and spatial drought propagation are mostly studied separately, it is yet unknown how drought spatial extent and connectedness ...

Linking community structure and climate vulnerability in desert plant assemblages of southern California

American Journal of Botany, EarlyView.
Abstract Premise Desert plant assemblages in southern California provide an opportunity to link patterns of community structure with climate‐driven vulnerability in a rapidly changing environment. California sustains an exceptionally diverse flora of approximately 4300 plant species, with 31% identified as endemic.

Unraveling drought propagation dynamics using causal inference from time series

Environmental Research Letters
Drought is a pervasive natural hazard that propagates through the hydrologic cycle, leading to water deficiencies across key hydroclimatic variables such as precipitation, streamflow, and soil moisture.

Event-scale investigation on spatiotemporal propagation dynamics between meteorological and agricultural drought

Agricultural Water Management
Meteorological drought can gradually propagate through land surface hydrological processes and further develop into agricultural drought, resulting in clear cascading propagation and time-lag responses between different drought types.

Triggering thresholds and influential factors in the propagation of meteorological drought to hydrological drought

Journal of Hydrology: Regional Studies
Study regions: The Huaihe River Basin (HRB), China Study focus: Quantifying the thresholds for the systematic propagation of meteorological drought (MD) to different levels of hydrological drought (HD) is essential for early warning and precision management of HDs.

Environmentally induced dynamics between intraindividual variation and trait means across vegetative, phenological, and floral traits

American Journal of Botany, EarlyView.
Abstract Premise Intraindividual variation in reiterated structures (e.g., leaves) represents an important dimension of phenotypic variation that contributes to functional diversity and the dynamics of ecological communities. It can be expressed differently across plant traits, but how environmental drivers affect intraindividual variation in different

Trigger thresholds and propagation mechanism of meteorological drought to agricultural drought in an inland river basin

Agricultural Water Management
Quantifying the thresholds and processes of drought propagation is of great significance for early drought warning and ecosystem management. Our understanding of their spatial patterns and driving mechanism remains unclear. In this study, based on Copula

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.
