Article Reference Remarks on Hymenoptera on urban green roofs in Belgium
In this paper we discuss all Hymenoptera (10.085 specimens) caught on several urban green roofs in Belgium during 2020 and 2021. We thereby try to connect species’ ecology and the specific habitat of extensive green roofs. Based on these findings we suggest what life communities can indeed be expected there. Six species on 120 taxa discovered are first reported for Belgium: Gonatopus lunatus (var. bifasciatus) Klug, 1810 (Aculeata: Dryinidae); Synacra paupera Macek, 1995 (Parasitica: Diapriidae); Alysia lucicola Haliday, 1838, Idiasta dichrocera Konigsmann, 1960 and Leiophron deficiens (Ruthe, 1856) (Parasitica: Braconidae) and Gelis declivis Forster, 1850 (Parasitica: Ichneumonidae).

Article Reference Remotely sensed seasonal dynamics of phytoplankton in the Ligurian Sea in 1997-1999.
Remotely sensed data and a one-dimensional hydrophysical model were used to study the seasonal dynamics of surface plant pigments concentration in the Ligurian-Provençal basin. The variations of phytoplankton biomass were estimated from the observations of the Coastal Zone Color Scanner (1978–1986) and Sea-viewing Wide Field-of-view Sensor (SeaWiFS) (September 1997 to October 1999) radiometers. The factors of physical environment analyzed included remotely sensed sea surface temperature (from advanced very high resolution radiometers), wind, air temperature, and atmospheric precipitation. The Geohydrodynamics and Environment Research (GHER) model was used to explain the observed correlations between the physical forcing and the response of phytoplankton biomass. The general pattern of phytoplankton seasonal dynamics was typical to subtropical areas: maximum biomass during cold season from October to April and low biomass during summer months. The intensity of winter/spring bloom significantly varied during different years. The correlation was revealed between the summer/autumn air temperature contrast (expressed as the difference between the air temperatures in August and in November) and the maximum monthly averaged surface chlorophyll concentration during the subsequent winter/spring bloom. The features of seasonal dynamics of phytoplankton are regulated by the physical impacts influencing water stratification. The difference between two seasonal cycles (from September 1997 to October 1999) illustrates the response of phytoplankton growth to local meteorological conditions. In March–April 1999 the vernal bloom was much more pronounced; it resulted from deeper winter cooling and more intensive winter convection. Heating of surface water layer, wind mixing, and freshwater load with rains and river discharge either stimulate or depress the development of phytoplankton, depending on what limiting environmental factor (light or nutrient limitation) prevailed.

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.

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.
