Zipping up the Synaptonemal Complex: Pathways to Homologous Chromosome Synapsis

BioEssays, Volume 48, Issue 1, January 2026.
The synaptonemal complex (SC) is a conserved protein structure that assembles between homologous chromosomes during meiosis. Here, we review pathways promoting homologous synapsis across model organisms, examining coordination with homolog pairing and recombination, spatiotemporal regulation of SC assembly, and the conserved molecular modules coupling ...

First European Interlaboratory Ring Test Study to Detect DNA of Crayfish and the Crayfish Plague Pathogen From Water Samples

Environmental DNA, Volume 8, Issue 1, January–February 2026.
This European interlaboratory ring test highlights how methodological differences affect eDNA‐based detection of crayfish and the crayfish plague pathogen, emphasizing the need for harmonized protocols to improve reliability in conservation and disease monitoring efforts.

The first large-scale genetic analysis of the vulnerable noble crayfish Astacus astacus reveals low haplotype diversity in central European populations

Knowledge and Management of Aquatic Ecosystems, 2011
Major global changes (e.g., human impact or climatic cycles) have a severe impact on the distribution and diversity of species such as the vulnerable European noble crayfish Astacus astacus.

Non-consumptive effects of native, alien and invasive alien crayfish on damselfly egg life history and carry-over effects on larval physiology [PDF]

NeoBiota
Invasive alien (IA) predators pose significant threats to native ecosystems, often leading to profound impacts on prey species through both direct and non-consumptive effects (NCE). This study focused on the NCE of predator-induced stress from one native

EVIDENCE OF COMMUNAL OVIPOSITION AND NEST ABANDONMENT IN THE NORTHERN TWO-LINED SALAMANDER (EURYCEA BISLINEATA, (GREEN, 1818)) IN NORTHEASTERN CONNECTICUT [PDF]

, 2014
Most plethodontid salamanders oviposit their eggs in an individual nest and attend the clutch until hatching. Here, we describe aspects of the reproduction of Eurycea bislineata (Northern Two-lined Salamander) from three field sites in northeastern ...

Diet‐manipulated body condition affects onset and speed of moult in common bulbuls in a tropical environment

Journal of Avian Biology, Volume 2026, Issue 1, January 2026.
Resource acquisition and allocation are central to life history theory, explaining the diversity of strategies among species as well as the distribution of events over the annual cycle. Moult is a major phase in the annual cycle of birds, but explanations for moult scheduling are heavily biased towards temperate systems with seasonal breeding patterns.
