Elevation, rather than land use, causes important dietary shifts in the Mediterranean golden eagle

Journal of Zoology, EarlyView.
In an ever‐changing landscape, golden eagles in the Iberian Peninsula demonstrate remarkable dietary adaptability. We monitored 50 distinct breeding events over 4 years using camera traps, collecting over 520 000 images. Elevation, rather than land use, emerged as the main driver of prey composition: lagomorphs and columbiforms dominated at lower ...

Silene, a versatile model system: from sex and genome evolution to ecology and speciation

New Phytologist, EarlyView.
Summary Fundamental and applied research in evolutionary biology benefits from the use of model systems in which approaches from disparate disciplines can be integrated. Here, we review recent progress in evolutionary research on the long‐standing model system Silene, a large genus with a well‐resolved phylogeny and newly available, expanded genomic ...

Aspects of genetic and morphological variation in selected new world land birds [PDF]

, 2000
Thesis (M.S.) University of Alaska Fairbanks, 2000The objective of this thesis is to examine variation in certain New World land birds, focusing on morphological difference at the intraspecific level and genetic differences at the intra- and ...

Postembryonic development of the predatory strike mechanics in a praying mantis (Insecta: Mantodea)

Physiological Entomology, EarlyView.
Praying mantis forelegs capture prey using specific kinematic and kinetic traits that change in size and morphology during postembryonic growth and sexual dimorphism influences these dynamics. Strike forces grow hyperallometrically with body weight; larger mantises show longer strike durations, slower joint angular velocities and increased tibia ...

Unveiling sex dimorphism in the healthy cardiac anatomy: Fundamental differences between male and female heart shapes

The Journal of Physiology, EarlyView.
Abstract figure legend We present a shape modelling‐based morphological analysis of sex differences in cardiac anatomy. We conduct our analysis on 456 healthy subjects from the UK Biobank (227M/229F) to uncover sex‐based differences in healthy cardiac morphology.

Wing morphology changes with habitat availability and elevation in an alpine-specialist bird

Global Ecology and Conservation
Intraspecific morphological variation of organisms is known to be influenced by several factors, but the role of habitat availability has been scarcely investigated.

Sensory Morphology of Geodorcus helmsi (Coleoptera: Lucanidae) and its Relevance to the Conservation of New Zealand Stag Beetles

New Zealand Journal of Zoology, Volume 53, Issue 2, June 2026.
Insects use sensilla to detect chemical and physical stimuli, mediating behaviours such as mate finding, foraging and mechanosensory responses. The distribution and density of sensilla can be examined using scanning electron microscopy. Investigating these structures can help elucidate rarely observed behaviours (e.g. mate finding and foraging).

Flooding affects fluctuating asymmetry but not growth of a riparian orbweaving spider

Ecological Entomology, Volume 51, Issue 3, Page 547-557, June 2026.
In a mesocosm experiment we assessed the impact of flood on aquatic insect emergence and on spider development using geometric morphometric analysis of fluctuating asymmetry. We observed 45% higher emergence in flooded mesocosm throughout the season. Spiders did not grow bigger but exhibited ~15% lower fluctuating asymmetry than in controls.

The Ultramorphology and Sexual Dimorphism of Antennae and Sensilla in the Pale Grass Blue, Pseudozizeeria maha (Lepidoptera: Lycaenidae)

Insects
The pale grass blue, Pseudozizeeria maha, is a small lycaenid butterfly widely distributed across Asia. Due to its exclusively diurnal lifestyle and conspicuous sexual dimorphism in wing coloration, vision has traditionally been regarded as the primary ...

Genome and transcriptome‐based identification and expression profiling of chemosensory gene families across developmental stages and tissues in Sirex noctilio (Hymenoptera: Siricidae)

Insect Molecular Biology, Volume 35, Issue 3, Page 270-283, June 2026.
The first draft genome of Sirex noctilio was produced. Fifteen S. noctilio transcriptomes were sequenced to study chemosensory gene expression patterns. SnocOR16 and SnocSNMP1 displayed tissue‐ and sex‐specific expression patterns. Abstract The Sirex woodwasp (Sirex noctilio; Hymenoptera: Siricidae) is among the most destructive invasive pests ...
