Hox Gene Variation Drives Morphological Specialization of Humpback Grouper Cromileptes altivelis

Integrative Zoology, EarlyView.
Cromileptes altivelis exhibits a distinctive “sunken head and humpback” morphology, formed through cranial remodeling. Genetic analyses identified unique amino acid variants in Hoxa7a and Hoxa10b, with functional tests confirming their role in enhancing osteoblast activity and driving cranial remodeling.

Extreme Silk Toughness in Caerostris Spiders Is Limited to Adult Females

Integrative Zoology, EarlyView.
We ask whether species with exceptionally tough silk, like Caerostris bark spiders, show different developmental patterns in silk toughness between ontogenetic stages and sexes. We found that only large females produce exceptionally tough silk with higher initial stiffness, while juvenile females as well as adult and juvenile males produce inferior ...

Pest‐preservation paradox among insects

Conservation Biology, EarlyView.
The pest‐preservation paradox is a non‐binary perspective that insects range from those that are harmful and requiring management on the one side, to those requiring conservation intervention on the opposite end of the spectrum. Importantly, the vast majority of insects occur somewhere in the center of the two extremes, and their position along the ...

Wt1 Is Required for the Regression of Müllerian Ducts in Male Mice by Inducing Wif1 and Osx Expression

Cell Proliferation, EarlyView.
Wt1 expressed in the MD mesenchyme promotes MD regression by inducing Wif1 and Osx transcription. In male mice, mesenchyme‐specific inactivation of Wt1 results in MD retention. ABSTRACT In mammals, Müllerian ducts (MDs) are the precursors of the female reproductive tract which regress in males during embryonic development.

The Great Dividing Range as a driver of genetic divergence in a low‐dispersing dragonfly

Ecological Entomology, EarlyView.
Population genomic analyses revealed low genetic differentiation and no discrete population structure across the Great Dividing Range, indicating widespread gene flow in Synthemis eustalacta. Genetic divergence was associated with environmental gradients, elevation and landscape resistance rather than geographic distance, supporting isolation by ...

Trans‐oceanic migration and wind utilization by Amur Falcons (Falco amurensis)

Ibis, EarlyView.
The Amur Falcon Falco amurensis performs one of the world's longest raptor migrations, involving a non‐stop crossing of the Indian Ocean of approximately 2800 km. While the existence of this route is known, the mechanistic details of wind exploitation and seasonal navigation remain to be fully elucidated.

The effects of Bacillus thuringiensis var. israelensis (Bti) on tropical stream food webs vary between two consecutive dry seasons

Insect Conservation and Diversity, EarlyView.
Bti application altered tropical stream food‐web structure through changes in macroinvertebrate functional feeding groups. Collector‐filterers and predators showed context‐dependent responses, with clearer direct and indirect effects detected in 2016, the year with higher rainfall.

Dragonfly functional connectivity responses are dynamic relative to drought

Insect Conservation and Diversity, EarlyView.
During drought, dragonfly species richness decreases. Yet, dragonfly assemblages show a higher propensity for dispersal during drought. Dispersal pathways vary among the wet and dry periods, and relative to temporal changes in the landscape. While some dragonfly species can traverse plantation compartments, conservation corridors facilitate functional ...

Dragonfly taxonomic and functional responses to urbanized streams in southeastern Europe, with management recommendations

Insect Conservation and Diversity, EarlyView.
Urbanization drives turnover in dragonfly species composition, traits, and habitat conservation value. Natural stream sections have a higher conservation value (higher DBI) due to presence of specialists. Properly managed urban streams can support diverse dragonfly assemblages.
