A pan‐metazoan concept for adult stem cells: the wobbling Penrose landscape
Biological Reviews, Volume 97, Issue 1, Page 299-325, February 2022., 2022 ABSTRACT Adult stem cells (ASCs) in vertebrates and model invertebrates (e.g. Drosophila melanogaster) are typically long‐lived, lineage‐restricted, clonogenic and quiescent cells with somatic descendants and tissue/organ‐restricted activities.

Ecology and Evolution, Volume 11, Issue 18, Page 12285-12293, September 2021., 2021 Sexual contact commonly occurs among insects (Eberhard, 1994). However, descriptions of precopulatory oral sexual contact in invertebrates remain rare and the evidence for an evolutionary function of precopulatory oral sexual contact is still lacking.

Andrology, Volume 9, Issue 5, Page 1617-1630, September 2021., 2021 Abstract Background Spermatogenesis is an elaborately organized and tightly regulated differentiation process. The spermatogenesis duration is stable within a certain species but highly variable between species of the same family. Objectives In this study, the spermatogenesis duration of the Roborovski hamster was measured for the first time, and the ...

Omics‐based molecular analyses of adhesion by aquatic invertebrates
Biological Reviews, Volume 96, Issue 3, Page 1051-1075, June 2021., 2021 ABSTRACT Many aquatic invertebrates are associated with surfaces, using adhesives to attach to the substratum for locomotion, prey capture, reproduction, building or defence. Their intriguing and sophisticated biological glues have been the focus of study for decades.

The repeatable opportunity for selection differs between pre‐ and postcopulatory fitness components
Evolution Letters, Volume 5, Issue 1, Page 101-114, February 2021., 2021 Abstract In species with multiple mating, intense sexual selection may occur both before and after copulation. However, comparing the strength of pre‐ and postcopulatory selection is challenging, because (i) postcopulatory processes are generally difficult to observe and (ii) the often‐used opportunity for selection (I) metric contains both ...

Optimized protocols for RNA interference in Macrostomum lignano
G3: Genes, Genomes, Genetics, 2023 Abstract Macrostomum lignano, a marine free-living flatworm, has emerged as a potent invertebrate model in developmental biology for studying stem cells, germline, and regeneration processes. In recent years, many tools have been developed to manipulate this worm and to facilitate genetic modification.

Journal of Evolutionary Biology, Volume 33, Issue 5, Page 714-726, May 2020., 2020 knockdown of the putative SFP Mlig‐pro63 resulted in a significantly decreased ‘suck’ propensity of mating partners upon ejaculate receipt, a behaviour by which the worm apparently attempts to remove the received ejaculate. Abstract The seminal fluid proteins (SFPs) transferred to mating partners along with sperm often play crucial roles in mediating ...

The effect of mating on female reproduction across hermaphroditic freshwater snails
Invertebrate Biology, Volume 139, Issue 1, March 2020., 2020 Abstract Sexual conflicts often arise between mating partners because each sex tries to maximize its own reproductive success. One major male strategy to influence a partner's resource allocation is the transfer of accessory gland proteins. This has been shown to occur in simultaneous hermaphrodites as well as in organisms with separate sexes. Although

Genotype‐by‐environment interactions for seminal fluid expression and sperm competitive ability
Journal of Evolutionary Biology, Volume 33, Issue 2, Page 225-236, February 2020., 2020 The simultaneously hermaphroditic flatworm Macrostomum lignano often performs a post‐mating suck behaviour thought to remove received ejaculate and thus a potential source of sexual conflict. Two suckless transcripts contributing to donor seminal fluid have been found to inhibit partners from sucking.

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 7, Page 879-894, 10 March 2025.Abstract Asbestos has been used extensively in several applications. Once it is known as a dangerous mineral, its usage has been prohibited and its identification and remediation play a very important role from the health safety point of view. Nowadays, deep learning techniques are used in many applications, especially for image analysis.
