The Australian Hydromyine Rodents—Their Interspecific Diversity and Reproductive Biology: A Review

open access: yesIntegrative Zoology, EarlyView.
There are two major groups, the Rattus species and the Hydromyini, in Australia. Clearly, the hydromyine rodents, unlike the Rattus genus, exhibit a diverse array of reproductive biological traits in both males and females, the full evolutionary significance of which has yet to be ascertained.

Nocturnal Behavior of Wintering Common Cranes (Grus grus) Under Varying Environmental Conditions

open access: yesIntegrative Zoology, EarlyView.
For diurnal species, nighttime represents a critical ecological boundary. Understanding the ecological determinants of nocturnal activity in taxa traditionally regarded as inactive after dusk is essential for elucidating the adaptive significance of nighttime behavior. We examined how night phase, nocturnal brightness (moon illumination and cloud cover)

Premium Intraocular Lens Selection in Patients With Glaucoma: A Clinical Review

open access: yesClinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Glaucoma frequently coexists with cataract, but glaucomatous functional loss, ocular‐surface disease, anatomical abnormalities, and treatment‐related refractive variability may reduce tolerance of premium intraocular lenses. This narrative review critically appraises evidence relevant to lens selection in glaucoma. Central visual‐field status,
