Island‐restricted reptiles are more threatened but less studied than their mainland counterparts

open access: yesConservation Science and Practice, EarlyView.
Reptiles are highly diverse on islands, yet there is no comprehensive overview of island‐restricted reptiles (IRRs) regarding their distribution, threat status, and research efforts. Our assessment revealed that despite IRRs comprising nearly a quarter of global reptile species and 30.8% being threatened, only 7.2% of the literature focuses on them ...

Genetic Mapping of Orofacial Traits Reveals a Single Genomic Region Associated With Differences in Multiple Parameters of Jaw Size Between Astyanax mexicanus Surface and Cavefish

open access: yesEvolution &Development, EarlyView.
By performing a genetic association study in cave × surface fish F2 hybrids, we discovered that premaxilla width, dentary length, and maxillary length are all significantly associated with a region on Chromosome 13 containing 109 genes. ABSTRACT The regulation of bone size is a poorly understood and complex developmental process.

Chrysoperla externa (Neuroptera: Chrysopidae) as a Potential Biological Control Agent of Raoiella indica (Acari: Tenuipalpidae)

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
First and third instar Chrysoperla externa showed efficient predatory capacity at low R. indica density, but second instar C. externa exhibits a density‐dependent predatory ability. The lacewing C. externa shows promise as a biocontrol agent for R. indica in coconut because it consumed 8362 R. indica females across all its larval instars.
