Jorissen, Auguste Chocha Manda, Célestin Danadu Mizani, Karen Smeets, Jos Snoeks, Gontran Sonet, Yang Tingbao, Maarten Van Steenberge, Emmanuel Vreven, Soleil Lunkayilakio Wamuini, Maarten P. M. Vanhove & Tine Huyse
During colonial times, Nile tilapia Oreochromis niloticus (Linnaeus, 1758) was introduced in non-native parts of the Congo Basin (Democratic Republic of the Congo, DRC) for the first time. Currently, it is the most farmed cichlid in the DRC, and is present throughout the Congo Basin. Although Nile tilapia has been reported as an invasive species, documentation of historical introductions into this basin and its consequences are scant. Here, we study the genetic consequences of these...

Data from: Wind-associated detours promote seasonal migratory connectivity in a flapping flying long-distance avian migrant

Gabriel Norevik, Susanne Akesson, Tom Artois, Natalie Beenaerts, Greg Conway, Brian Cresswell, Ruben Evens, Ian Henderson, Frederic Jiguet & Anders Hedenström
1. It is essential to gain knowledge about the causes and extent of migratory connectivity between stationary periods of migrants to further the understanding of processes affecting populations, and to allow efficient implementation of conservation efforts throughout the annual cycle. Avian migrants likely use optimal routes with respect to mode of locomotion, orientation and migration strategy, influenced by external factors such as wind and topography. In self-powered flapping flying birds any increases in fuel loads...

Environmental safety of consumer products: legal and regulatory issues

D.G. Domrachev, А.А. Kirillovykh, V.N. Pugach & Y.M. Gordeeva
Modern problems of ensuring ecological safety of consumer products in the Russian Federation are considered, and also measures for improvement of the mechanism of regulation of quality and ecological safety in the sphere of consumption are offered. The methodological basis of the research is the analytical method, which allows to consider the practice of regulation of the environmental safety of products, the formal legal method, which allows to reveal the systemic connections in legal regulation,...

Redefining Near-Unity Luminescence in Quantum Dots with Photothermal Threshold Quantum Yield

David Hanifi, Noah Bronstein, Brent Koscher, Zach Nett, Joseph Swabeck, Kaori Takano, Adam Schwartzberg, Lorenzo Maserati, Koen Vandewal, Yoeri Van De Burgt, Alberto Salleo & Paul Alivisatos
Herin is the code and example data sets for the publication titled: "Redefining Near-Unity Luminescence in Quantum Dots with Photothermal Threshold Quantum Yield." The abstract of this paper is as follows. A variety of optical applications rely on the absorption and reemission of light. The quantum yield of this process often plays an essential role. When the quantum yield deviates from unity by significantly less than 1%, applications such as luminescent concentrators and optical refrigerators...

Data from: Lyme neuroborreliosis and bird populations in northern Europe

Atle Mysterud, Dieter Heylen, Erik Mathyssen, Aïda Garcia, Solveig Jore & Hildegunn Viljugrein
Many vector-borne diseases are transmitted through complex pathogen-vector-host networks, which makes it challenging to identify the role of specific host groups in disease emergence. Lyme borreliosis in humans is now the most common vector-borne zoonosis in the northern hemisphere. The disease is caused by multiple genospecies of Borrelia burgdorferi sensu lato bacteria transmitted by ixodid (hard) ticks, and the major host groups transmit Borrelia genospecies with different pathogenicity, causing variable clinical symptoms in humans. The...

Data from: Convergent losses of decay mechanisms and rapid turnover of symbiosis genes in mycorrhizal mutualists

Annegret Kohler, Alan Kuo, Laszlo G. Nagy, Emmanuelle Morin, Kerrie W. Barry, Francois Buscot, Bjorn Canback, Cindy Choi, Nicolas Cichocki, Alicia Clum, Jan Colpaert, Alex Copeland, Mauricio D. Costa, Jeanne Dore, Dimitrios Floudas, Gilles Gay, Mariangela Girlanda, Bernard Henrissat, Sylvie Herrmann, Jaqueline Hess, Nils Hogberg, Tomas Johansson, Hassine-Radhouane Khouja, Kurt LaButti, Urs Lahrmann … & Francis Martin
To elucidate the genetic bases of mycorrhizal lifestyle evolution, we sequenced new fungal genomes, including 13 ectomycorrhizal (ECM), orchid (ORM) and ericoid (ERM) species, and five saprotrophs, which we analyzed along with other fungal genomes. Ectomycorrhizal fungi have a reduced complement of genes encoding plant cell wall–degrading enzymes (PCWDEs), as compared to their ancestral wood decayers. Nevertheless, they have retained a unique array of PCWDEs, thus suggesting that they possess diverse abilities to decompose lignocellulose....

Mapping species richness using opportunistic samples: a case study on ground-floor bryophyte species richness in the Belgian province of Limburg

Thomas Neyens, Peter Diggle, Christel Faes, Natalie Beenaerts, Tom Artois & Emanuele Giorgi
In species richness studies, citizen-science surveys where participants make individual decisions regarding sampling strategies provide a cost-effective approach to collect a large amount of data. However, it is unclear to what extent the bias inherent to opportunistically collected samples may invalidate our inferences. Here, we compare spatial predictions of forest ground-floor bryophyte species richness in Limburg (Belgium), based on crowd- and expert-sourced data, where the latter are collected by adhering to a rigorous geographical randomisation...

Temporally consistent species differences in parasite infection but no evidence for rapid parasite-mediated speciation in Lake Victoria cichlid fish

Tiziana P Gobbin, Maarten PM Vanhove, Antoine Pariselle, Ton GG Groothuis, Martine E Maan & Ole Seehausen
Parasites may have strong eco-evolutionary interactions with their hosts. Consequently, they may contribute to host diversification. The radiation of cichlid fish in Lake Victoria provides a good model to study the role of parasites in the early stages of speciation. We investigated patterns of macroparasite infection in a community of 17 sympatric cichlids from a recent radiation and 2 older species from 2 non-radiating lineages, to explore the opportunity for parasite-mediated speciation. Host species had...

Summary of the microsatellite genotyping analysis of 280 C. gariepinus samples originating from eight locations in the Congo basin using five microsatellite markers

Aim The formation history of Africa’s current river basins remains largely unknown. In order to date changes in landscape and climate, we studied the biogeography of the African freshwater fish with the largest natural distribution. We also validated biogeographic units. Location Continental Africa. Taxon Clarias gariepinus sl. Methods We investigated mitochondrial cytb sequences of 443 individuals from 97 localities, using a haplotype network and a genetic landscape analysis. We inferred a dated phylogeny using maximum...

Data from: Early detection of chronic hepatitis B and risk factor assessment in Turkish migrants, Middle Limburg, Belgium.

Özgür Muhammet Koc, Cécile Kremer, Niel Hens, Rob Bielen, Dana Busschots, Pierre Van Damme & Geert Robaeys
Background Turkey is an intermediate hepatitis B virus (HBV) endemic country. However, prevalence among Turkish migrants in Belgium is unknown, especially in those born in Belgium with a foreign-born parent, i.e. second-generation migrants (SGM). Aims To evaluate the prevalence of HBV infection and associated risk factors in Turkish first-generation migrants (FGM), i.e. foreign-born, and SGM. Methods Between September 2017 and May 2019, free outreach testing for hepatitis B surface antigen (HBsAg), hepatitis B core antibodies...

Data from: Study on the foraging behaviour of the European nightjar Caprimulgus europaeus reveals the need for a change in conservation strategy in Belgium

Ruben Evens, Natalie Beenaerts, Nele Witters & Tom Artois
Effective nature conservation requires coherent actions based on the best available evidence concerning protected species. Recent studies have suggested that European nightjars Caprimulgus europaeus forage outside their recognized breeding habitats, yet, for Flanders (northern Belgium) information on nightjar foraging behaviour and key foraging habitats is lacking. To assess whether the foraging ecology of nightjars in Flanders is similar to that observed in other parts of Europe, we studied the crepuscular behaviour of this species in...
