Lagging spawning and increasing phenological extremes jeopardize walleye (Sander vitreus) in north‐temperate lakes

open access: yesLimnology and Oceanography Letters
The phenology of critical biological events in aquatic ecosystems is rapidly shifting due to climate change. Growing variability in phenological cues can increase the likelihood of trophic mismatches (i.e., mismatches in the timing of peak prey and ...

open access: yesNordic Journal of Botany, EarlyView.
Eriope (Lamiaceae) is a Neotropical genus primarily found in Brazil's Campos Rupestres and extending to other South American regions. It was confirmed as monophyletic in recent molecular studies and includes over 30 species. Originally described with 13 species, the genus expanded through further classifications and revisions. Recent fieldwork in Monte
