Sex Determination in Sponges

Molecular Reproduction and Development, Volume 93, Issue 6, June 2026.
ABSTRACT Sex determination in Porifera remains one of the least understood aspects of early metazoan biology despite the group's key phylogenetic position. Sponges display exceptional diversity in sexual systems—ranging from stable gonochorism to sequential hermaphroditism and sex reversal—yet lack morphological dimorphism and any discrete gonadal ...

North American velvet ants form one of the world’s largest known Müllerian mimicry complexes

, 2015
SummaryColor mimicry is often celebrated as one of the most straightforward examples of evolution by natural selection, as striking morphological similarity between species evolves in response to a shared predation pressure [1].

Uncovering the effects of Müllerian mimicry on the evolution of conspicuousness in colour patterns

, 2022
Variation in the conspicuousness of colour patterns is observed within and among defended prey species. The evolution of conspicuous colour pattern in defended species can be strongly impaired because of increased detectability by predators. Nevertheless,

Persistence of multiple patterns and intraspecific polymorphism in multi-species Müllerian communities of net-winged beetles

Frontiers in Zoology, 2019
Background In contrast to traditional models of purifying selection and a single aposematic signal in Müllerian complexes, some communities of unprofitable prey contain members with multiple aposematic patterns.

Australian Mistletoe‐Host Leaf Resemblance: Support for Eco‐Physiological Convergence Rather Than Disperser‐ or Herbivore‐Driven Mimicry

Austral Ecology, Volume 51, Issue 6, June 2026.
ABSTRACT Presently, there are three main hypotheses to explain why the leaves of many Australian mistletoes resemble their hosts. The eco‐physiological convergence hypothesis suggests that mistletoes must manage their physiology, especially their water relations, to match those of the host, to avoid killing themselves or the host branch they have ...

The Homeobox Genes: Classification, Regulation, Biological Functions, and Diseases

MedComm, Volume 7, Issue 4, April 2026.
Overview of the homeobox gene superfamily and its pathophysiological roles. The homeobox superfamily comprises several major classes, including ANTP, PRD, TALE, LIM, POU, and others. Among these, the HOX clusters (A–D) play critical roles in embryonic development specifically in conferring cellular identity, regulating morphogenesis, and guiding axial ...

Müllerian mimicry of a quantitative trait despite contrasting levels of genomic divergence and selection [PDF]

, 2020
Hybrid zones, where distinct populations meet and interbreed, give insight into how differences between populations are maintained despite gene flow.

Folate receptor alpha (FRα) expression in tubo‐ovarian and endometrial tumors: a study of 923 cases

The Journal of Pathology: Clinical Research, Volume 12, Issue 2, March 2026.
Abstract Folate receptor alpha (FRα) is a promising therapeutic target due to its high expression in several tumor types and its rare expression in healthy tissue. Recently, the antibody‐drug conjugate mirvetuximab soravtansine has been approved for treatment of advanced platinum‐resistant high‐grade serous carcinoma (HGSC).

Changes in the Mare Oviduct Across Different Seasons Throughout the Year

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
Checking changes throughout the year in the oviductal structure (anatomy, permeability, oviductal cellularity and the presence of pathologies) may be relevant to understand the influence on the appearance of problems in oviductal functionality. The oviducts of 56 mares were examined, and the correlations between the time of the year and each of these ...
