Thyroid hormone receptor orthologues from invertebrate species with emphasis on
BMC Evolutionary Biology, 2007 Background: Thyroid hormone receptors (TRs) function as molecular switches in response to thyroid hormone to regulate gene transcription. TRs were previously believed to be present only in chordates. Results: We isolated two TR genes from the Schistosoma

Trematode diversity reflecting the community structure of Danish freshwater systems: molecular clues
Parasites & Vectors, 2021 Background Digenean trematodes are parasitic platyhelminths that use several hosts in their life cycles and are thereby embedded in various ecosystems affected by local environmental conditions.

Microbial Metazoa Are Microbes Too
mSystems, 2019 Microbial metazoa inhabit a certain “Goldilocks zone,” where conditions are just right for the continued ignorance of these taxa. These microscopic animal species have body sizes of

Evidence for adaptive explanations of semelparity in animals
Biological Reviews, EarlyView.ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Mixed infections and hybridisation in monogenean parasites. [PDF]
PLoS ONE, 2012 Theory predicts that sexual reproduction promotes disease invasion by increasing the evolutionary potential of the parasite, whereas asexual reproduction tends to enhance establishment success and population growth rate.

Chemistry – A European Journal, EarlyView.Balancing Act: Se─M bond serving as the fulcrum of the balance scale to compare the different weight of toxicity and therapeutic effects in biological environment. ABSTRACT The synthesis and characterization of organo‐selenium compounds have attracted considerable interest for decades, driven by the search for efficient catalysts and bioinspired ...

Methods in Ecology and Evolution, EarlyView.Abstract The biodiversity crisis demands new approaches to describing and characterising species that can scale beyond the capacity of professional taxonomists alone. Hundreds of millions of specimen images are now openly available, yet almost none carry structured information about the morphology they depict. We present the Descriptron‐GBIF Annotator,

The Embryonic Development of the Cotylean Polyclad Phrikoceros jannetae
Acta Zoologica, EarlyView.ABSTRACT Polyclads exhibit distinct developmental modes ranging from direct to indirect development, with several transitional stages also recognised. The existence of an indirect developmental mode in polyclads with a planktonic life history stage in the form of a free‐swimming larva is unique among all free‐living flatworms and makes polyclads a ...

Planarian (Platyhelminthes, Tricladida) Diversity and Molecular Markers: A New View of an Old Group
Diversity, 2014 Planarians are a group of free-living platyhelminths (triclads) best-known largely due to long-standing regeneration and pattern formation research. However, the group’s diversity and evolutionary history has been mostly overlooked.

Acta Zoologica, EarlyView.ABSTRACT This study presents a formal description and taxonomic appraisal of Cacatuocotyle adrianoi sp. n., a Neotropical parasite belonging to the family Dactylogyridae, integrating AI‐assisted morphometric analyses, molecular data, and phylogenetic reconstruction. Phylogenetic analyses recovered Cacatuocotyle adrianoi sp. n.
