ABSTRACT The invasive freshwater jellyfish Craspedacusta sowerbii, likely of Asian origin, is globally distributed, yet its invasion history in South America remains poorly understood. Following a mass mortality event of tilapia (Oreochromis niloticus) during a jellyfish bloom in Paraná, Brazil, in March 2022, we conducted morphological and molecular ...

Modeling Phenotypic Trait Variation and Plasticity in Elymus elymoides to Guide Climate‐Informed Seed Transfer

open access: yesEvolutionary Applications, Volume 19, Issue 3, March 2026.
ABSTRACT Information on climate‐associated phenotypic variation is essential for sourcing seed that matches restoration site conditions. Spatially explicit seed transfer models can effectively deliver this information. However, standard modeling approaches often do not provide flexibility for practical considerations and may not capture highly complex ...

Pacing Early Mars Sedimentary Rock Formation

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Mars' sedimentary rock record documents past surface and/or near‐surface liquid water. However, paleoclimate models struggle to explain conditions warm enough for past liquid water. One hypothesis is transient warming by H2 ${\mathrm{H}}_{2}$‐CO2 ${\text{CO}}_{2}$ collision‐induced absorption (CIA) (H2 ${\mathrm{H}}_{2}$‐CO2 ${\text{CO}}_{2 ...
