Article Reference Repeated unidirectional introgression of nuclear and mitochondrial DNA between four congeneric Tanganyikan cichlids.
With an increasing number of reported cases of hybridization and introgression, interspecific gene flow between animals has recently become a widely accepted and broadly studied phenomenon. In this study, we examine patterns of hybridization and introgression in Ophthalmotilapia spp., a genus of cichlid fish from Lake Tanganyika, using mitochondrial and nuclear DNA from all four species in the genus and including specimens from over 800 km of shoreline. These four species have very different, partially overlapping distribution ranges, thus allowing us to study in detail patterns of gene flow between sympatric and allopatric populations of the different species. We show that a significant proportion of individuals of the lake-wide distributed O. nasuta carry mitochondrial and/or nuclear DNA typical of other Ophthalmotilapia species. Strikingly, all such individuals were found in populations living in sympatry with each of the other Ophthalmotilapia species, strongly suggesting that this pattern originated by repeated and independent episodes of genetic exchange in different parts of the lake, with unidirectional introgression occurring into O. nasuta. Our analysis rejects the hypotheses that unidirectional introgression is caused by natural selection favoring heterospecific DNA, by skewed abundances of Ophthalmotilapia species or by hybridization events occurring during a putative spatial expansion in O. nasuta. Instead, cytonuclear incompatibilities or asymmetric behavioral reproductive isolation seem to have driven repeated, unidirectional introgression of nuclear and mitochondrial DNA into O. nasuta in different parts of the lake.

Book Reference Report often years of Mollusca collection in Icelandic waters by the Marine and Freshwater Research Institute
Over a period of 10 years (October 2013 - March 2022) sampling effort was operated by the Fisheries and Benthic scientists of the Marine and Freshwater Research Institute (MFRI) to keep molluscs specimens collected as by-catch when trawling during fish stock assessment around Iceland. These trawls were primarily made during deep-sea surveys (autumn campaign), as well as on shallower fishing grounds north-west of Iceland (March campaign). Some campaigns in May for stock evaluation of lobster (Nephrops norvegicusj and in August for flat fish surveys also contributed with samples. The size of the mesh of the trawls allowed mainly collection of macro-molluscs. Smaller molluscs (<10 mm) were collected in the stomach and gut of captured fish, mainly haddock (Melanogrammus aeglefinusj and long rough dab (Hippoglossoides platessoidesj. By-catches from different origins (stones, shell debris, ghost fishing nets, sponges, corals, seaweeds, kelp holdfast, sweep ups) were photographed and analysed to isolate eventual hidden molluscs. The state of the sampled molluscs, alive or dead (empty shells), is reported in all cases.

Inproceedings Reference Restoring nature's health: Investigating the effects of ecosystem restoration on zoonotic disease risk
Emerging infectious diseases (EIDs) pose a significant threat to global public health. Among the factors contributing to the increase of EIDs today, habitat degradation stands out as a prominent driver, exerting both direct and indirect influences on disease dynamics. While it is commonly assumed that simply reversing ecosystem degradation will restore disease regulation mechanisms, such a presumption may oversimplify the complex response involved. My PhD project aims to delve deeper into the mechanisms underlying the impact of ecosystem restoration on zoonotic disease risk by examining terrestrial small mammal (TSM) and microparasite diversity within sampling sites following a chronosequence of ecosystem restoration in the Congo Basin. Through comprehensive sampling methods, including the capture of TSMs, and collection of iDNA and acoustic samples, the project will investigate how small mammal and microparasite diversity and prevalence evolve over time post-restoration. An emphasis will be placed on a subset of vector-borne and directly transmitted microparasites associated with African TSMs frequently found in the Congo Basin (i.e. Hepaciviruses, Paramyxoviruses, Orthonairovirus, Leptospira, Bartonella, and Anaplasma). The findings of this study will help unravel the complex interactions between ecosystem restoration, biodiversity, and zoonotic disease risk, offering crucial insights for the improvement and safeguarding of human, animal, and ecosystem health. This research is situated within the framework of the RESTOREID project (Horizon Europe; PI: Herwig Leirs), which aims to investigate the role of landscape restoration in mitigating disease risk using various field sites in Europe and Africa.

Article Reference Resultados de la 14a campaña de excavación arqueológica del Proyecto Qubbet el-Hawa de la Universidad Jaén en Asuán (Egipto) (2022)
El presente artículo proporciona información sobre los resultados preliminares de la 14ª campaña de excavación arqueológica del Proyecto Qubbet el-Hawa de la Universidad de Jaén. Desde hace más de una década, el proyecto desarrolla su investigación en la necrópolis más meridional de Egipto. Consideramos importante destacar las nuevas incorporaciones al equipo interdisciplinar que han permitido, entre otros avances, el estudio de las momias de cocodrilos halladas con anterioridad o el descubrimiento de una mina de época bizantina. Sin embargo, también es destacable la continuación de otros estudios ya iniciados en anteriores campañas e incluso la finalización de los trabajos arqueológicos en diferentes áreas de la colina. Sin duda, y como cada año, el Proyecto Qubbet el-Hawa puede congratularse de la realización de una campaña exitosa, llena de resultados muy relevantes para la investigación.

Article Reference Results of ant collections on Santa Cruz Island within the framework of the 2012 Global Taxonomy Initiative Ant Course at Galápagos (Hymenoptera: Formicidae)
During a ten-days ant course carried out in November 2012 within the framework of a Belgian Focal Point to the Global Taxonomy Initiative GTI type 2 grant, eight students and four instructors collected 22 ant species at ten sites distributed along an altitudinal gradient on Santa Cruz Island in the Galápagos Archipelago (Ecuador). Disturbed and urbanized zones as well as natural areas were visited. We discuss the results and link the collected species to altitude and vegetation types occurring on Santa Cruz Island.

Article Reference Resurrection and neotype designation of Pilumnus spinulosus Kessler, 1861 (Crustacea: Decapoda)
ABSTRACT. The scientific name Pilumnus spinulosus Kessler, 1861 is resurrected for the representatives of the brachyuran genus Pilumnus Leach, 1816 (Decapoda: Brachyura: Pilumnidae), occurring along the northern coastal line of the Black Sea. This species has been mistakenly identified as P. hirtellus (Linnaeus, 1761) and recently, based on DNA data, referred to as P. aestuarii Nardo, 1869. Furthermore, a neotype of P. spinulosus Kessler, 1861 is designated as the original material is presently considered as lost. P. hirtellus ponticus Czerniavsky, 1868, P. aestuarii Nardo, 1869, P. hirtellus intermedia Czerniavsky, 1884 are considered as junior synonyms of P. spinulosus Kessler, 1861. РЕЗЮМЕ. Научное название Pilumnus spinulosus Kessler, 1861 восстановлено для представителей рода Pilumnus Leach, 1816 (Decapoda: Brachyura: Pilumnidae), встречающегося вдоль северной бере- говой линии Черного моря. Ранее этот вид был ошибочно идентифицирован как P. hirtellus (Linnaeus, 1761), а позднее, на основании данных ДНК, отнесён к P. aestuarii Nardo, 1869. Видовые назва- ния P. hirtellus ponticus Czerniavsky, 1868, P. aestuarii Nardo, 1869, P. hirtellus intermedia Czerniavsky, 1884 рассматриваются как младшие синонимы P. spinulosus Kessler, 1861.
