Generation of Knock‐In Syrian Hamsters via Zygote Microinjection Using CRISPR/Cas9 Genome Editing

open access: yesgenesis, Volume 63, Issue 5, October 2025.
ABSTRACT Syrian hamsters (Mesocricetus auratus) have long served as valuable model organisms in diverse research fields such as oncology, immunology, and physiology owing to their unique biological and pathological characteristics. Although embryo manipulation techniques such as embryo collection, pronuclear microinjection, and embryo transfer have ...

Non‐native prey availability and over‐compensatory density dependence drive population dynamics of a native fish predator

open access: yesEcological Applications, Volume 35, Issue 7, October 2025.
Abstract Understanding the factors that regulate population dynamics is crucial for conserving imperiled species. Bull trout (Salvelinus confluentus), a piscivorous salmonid and one of North America's most threatened cold‐water species, has declined significantly due to habitat loss, overfishing, invasive species, and climate change.

Weight‐Length Ratio of Piranhas Serrasalmus (Characiformes, Serrasalmidae) in Bolivia: Relationships to Molecular Divergence and Maximum Size?

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
This study presents WLRs of nine piranha or palometa fish species of genus Serrasalmus present in the Amazon and La Plata basins of Bolivia and compares differences with genetic divergence (mtDNA COI locus) and the observed maximum size. All species showed an exponential (power type) growth pattern, and all WLRs were significantly different among all ...

Stronger Antipredatory Vigilance of Prey to Olfactory Cues From Injured Vulnerable Conspecifics

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
Eggs of spider mites are more vulnerable to predators. Reproductive females of spider mites are more vigilant to olfactory cues from injured eggs compared to that from injured adults and deutonymphs. ABSTRACT Predation risk is a key evolutionary force shaping prey behaviors and life‐history strategies across taxa. Predators often target vulnerable life
