Influence of elevation, climate, snowmelt and floral abundance on body size of solitary bees
Ecological Entomology, EarlyView.We measured body size in bee species from a 10‐year specimen collection from Colorado sub‐alpine meadows (2450–3450 m) and tested effects of elevation and annual snowmelt, climate and floral abundance. 2 out of 4 bee species collected across a broad elevation range showed a decline in body size with higher elevations; the other two showed no effect ...

Cellular signals controlling oocyte activation
Cellular signals controlling oocyte activation. This research will significantly advance our understanding of the basic biological processes that underpin the fertility rate of all mammals and are key to the immediate and future health and well-being of ...

Fish and Fisheries, EarlyView.ABSTRACT Estimating the number of spawning events per female is key to understanding reproductive output in batch‐spawning species, yet direct observation is often infeasible in the wild. Recent advances in genetic kinship inference enable the identification of maternal half siblings from young‐of‐the‐year genomic samples, while otolith‐based age ...

The FEBS Journal, EarlyView.DNA damage in the tardigrade Hypsibius exemplaris elicits distinct cellular outcomes depending on replication status. While non‐replicating cells tolerate genotoxic stress, constitutively replicating cells undergo irreversible replication failure upon DNA damage, leading to loss of tissue homeostasis, fat depletion, sterility, and organismal death ...

Phosphorylation of BigH1 regulates its expression pattern and promotes embryonic development
The FEBS Journal, EarlyView.Phosphorylation is a key regulator of the linker histone variant BigH1 during Drosophila embryogenesis. We reveal that N‐terminal phosphorylation promotes the timely removal of BigH1 from chromatin. In contrast, C‐terminal phosphorylation supports early nuclear divisions and embryonic viability.
