Functional anatomy, jaw mechanisms, and feeding behavior of Dunkleosteus terrelli (Placodermi, Arthrodira)

The Anatomical Record, Volume 309, Issue 10, Page 2574-2635, October 2026.
A new musculoskeletal reconstruction and revision of the cranio‐mandibular anatomy of the Devonian arthrodire placoderm Dunkleosteus terrelli from a comparative and functional anatomical perspective. Dunkleosteus is a specialized arthrodire with many specializations for feeding on large vertebrates, and many of its features are part of broader ...

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

Biological Reviews, Volume 101, Issue 5, Page 2081-2102, October 2026.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

Omnidens appendages and the origin of radiodont mouthparts

Papers in Palaeontology
AbstractThe sophisticated, modular and adaptable body plan of arthropods underpins their dominance in marine invertebrate communities. The origin of this body plan from legged lobopodian worms can be inferred from Cambrian Konservat‐Lagerstätten, but our understanding retains some notable gaps: not least in the transition from swimming lobopodians such

Desert Milkweed (Asclepias erosa) as a Midsummer Resource for Arthropod Communities in the Great Basin Desert

Ecology and Evolution, Volume 16, Issue 10, October 2026.
BLURB FOR ETOC: In the Great Basin Desert, many plants senesce as heat and drought intensify in midsummer, potentially concentrating arthropods on the few species that remain physiologically active. We surveyed arthropods on desert milkweed (Asclepias erosa) during this period and recorded 1779 individuals representing 67 morphospecies across 41 plants;

Heterobathmia pseuderiocrania (Heterobathmiina): mouthparts, mouthpart sensilla, and comparison with other non-glossatan suborders (Insecta, Lepidoptera)

Revista del Museo Argentino de Ciencias Naturales, 2005
The mouthparts of Heterobathmia pseuderiocrania are primitive and well adapted for collecting and grinding pollen of Nothofagus. The five- segmented maxillary palps show specialized structures for collecting pollen: spatula-shaped sensilla chaetica.

Ranavirus risk depends on host community characteristics more than the presence of Batrachochytrium dendrobatidis

Oikos, Volume 2026, Issue 10, October 2026.
Novel parasite introductions are threatening wildlife communities globally. The degree of threat depends on the ecological context, namely host community characteristics and the presence of other parasites. How these two factors interact to shape the outcomes of parasite introductions is not known. We experimentally investigated how infection following

Large‐flowered stapeliad Edithcolea grandis (Apocynaceae: Asclepiadoideae) is pollinated by dung‐ and blood‐feeding African face flies (Muscidae: Musca xanthomelas)

TAXON, Volume 75, Issue 5, October 2026.
Abstract The more than 360 species of stem‐succulent stapeliads in the tribe Ceropegieae represent a perfect example for species radiation and diversification in response to pollination by flies. In the majority of species, the myiophilous flowers have visual and olfactory characteristics that suggest carrion or dung mimicry.

Distinctive gene expression in the reduced first thoracic legs of a nymphalid butterfly

Insect Molecular Biology, Volume 35, Issue 5, Page 504-516, October 2026.
Transcriptome analysis reveals that the small non‐walking front legs of a butterfly have distinct gene expression to the four walking legs. Reduced front legs express a gene with putative mechanosensory roles, a blue‐sensitive opsin and two homeobox genes.

Polyphenism Through RNA Chemical Modifications

Molecular Ecology, Volume 35, Issue 19, October 2026.
ABSTRACT Polyphenism, the capacity of a single genotype to produce discrete phenotypes in response to environmental cues, has long served as a model for understanding developmental plasticity. While classical studies have highlighted hormonal signalling and transcription‐factor‐driven gene regulatory networks that mediate these environmentally induced ...

The Mouthparts of Ants

, 2001
Ant mandible movements cover a wide range of forces, velocities and precision. The key to the versatility of mandible functions is the mandible closer muscle. In ants, this muscle is generally composed of distinct muscle fiber types that differ in morphology and contractile properties.
