A naturalist’s life would be a happy one if he had only to observe and never to write. Charles Darwin Acknowledgments My Ph.D. thesis was made possible through a FWO (Fonds Wetenschappelijk Onderzoek - Vlaanderen) project-collaboration between the University of Antwerp and the Catholic University of Leuven. First of all, I wish to thank Marcel Eens, the head of the Biology-Ethology research group in Antwerp, who supervised me during all phases of my thesis. Marcel, I am very grateful for your trust and patience. You gave me confidence and incentive during this difficult journey. Hartelijk bedankt! In Leuven, I was guided by Filip Volckaert, the head of the Biodiversity and Evolutionary Genomics research group, and Gregory Maes. I truly appreciate all your time, patience, knowledge, spontaneous inputs and happy welcomes that you gave me. I learned a lot; also things that go beyond this thesis and are not included in it. Cheers! I also wish to thank my other jury and committee members. Thanks Lieven Bervoets, Gudrun de Boeck, Erik Matthysen and Michael Ovidio for your contribution. I really appreciate it. In the first two months of my work for this thesis, I had also a co-supervisor, Guy Knaepkens, who had initiated the FWO project together with Greg. Although our collaboration was only of short duration, I am happy to have met you. Thanks for believing in my abilities to achieve this high goal. Jammer dat we samen niet meer donderpadden konden vangen. In Leuven, I met Alexandros Triantafyllidis, who was in Filip’s lab for a half year sabbatical. You invested a large part of your time into the “bullhead research”, I am grateful for all your interest and your help to guide me into the world of population genetics. I also met Bart Hellemans in Leuven, a very nice person and true connoisseur of genetic techniques and theory. I learned a lot and really enjoyed working together with you in the laboratory. I got much support from the Ethology research group and I want to name the people that had their part in this thesis, motivated me, taught me Dutch and/or gave me friendship: Berber De Jong (Smakelijk!), Geert Eens, Igor Eulaers, Laszlo Garamszegi (Egészségedre!), Ann Geens (was good to have a nice fairy in the office!), Hector Rivera Gutierrez, Veerle Jaspers, Stefanie Lahaye (keep me updated about the villa), Carsten Lucass, Josie Meaney-Ward, Wendt Müller, Rianne Pinxten, Maud Poisbleau, Peter Scheys (Petri Heil!), Jeff Van Camp, Evi Van 4 den Steen (was wel een leuke tijd), Alain Van Hout, Jonas Vergauwen. Thanks a lot, I have lovely memories of all of you. During my thesis I also shared great moments with the students that I supervised. Big cheers goes out to Dimitri Geelhand de Merxem, Katia Geudens, Yves Humblet and Sofie Vanwetswinkel. I was always warm-hearted welcomed in the Leuven lab.

  • Use of Stream Mouth Habitats by Cottus Perifretum and Leuciscus Cephalus Along the River Meuse (The Netherlands)
    Folia Zool. – 59(1): 44 –50 (2010) Use of stream mouth habitats by Cottus perifretum and Leuciscus cephalus along the River Meuse (the Netherlands) Bart J.A.

Cottus perifretum is a resident species, using these stream mouth habitats throughout its entire life: i.e. as a spawning, nursery and adult habitat. Leuciscus cephalus is a transient species that uses these stream mouth habitats only as a temporary 0+ juvenile habitat during fall and early winter. This study suggests that the stream mouth habitats along the river Meuse fulfil different ecological functions forC. perifretum and L. cephalus.

  • Contrasting Life Histories Contribute to Divergent Patterns of Genetic
    Baek et al. BMC Evolutionary Biology (2018) 18:52 https://doi.org/10.1186/s12862-018-1171-8 RESEARCH ARTICLE Open Access Contrasting life histories contribute to divergent patterns of genetic diversity and population connectivity in freshwater sculpin fishes Song Yi Baek1, Ji Hyoun Kang2, Seo Hee Jo1, Ji Eun Jang3, Seo Yeon Byeon1, Ju-hyoun Wang4, Hwang-Goo Lee4, Jun-Kil Choi4 and Hyuk Je Lee1* Abstract Background: Life history characteristics are considered important factors influencing the evolutionary processes of natural populations, including the patterns of population genetic structure of a species. The sister species Cottus hangiongensis and C. koreanus are small bottom-dwelling freshwater sculpin fishes from South Korea that display marked life history divergence but are morphologically nearly indistinguishable. Cottus hangiongensis evolved an ‘amphidromous’ life history with a post-hatching pelagic larval phase. They spawn many small eggs in the low reaches of rivers, and hatched larvae migrate to the sea before returning to grow to maturity in the river mouth. In contrast, C. koreanus evolved a ‘fluvial’ landlocked type with benthic larvae. They release a smaller number of larger eggs, and the larvae undergo direct development, remaining benthic in the upstream rivers throughout their entire lives. We tested whether there were differences in patterns and levels of within-population genetic diversities and spatial population structure between the two closely related Korean sculpins using mitochondrial DNA control region sequences and seven nuclear microsatellite loci. Results: The combined analyses of both marker sets revealed that C. hangiongensis harboured considerably higher levels of within-population genetic diversities (e.g.

  • Master List of Fishes
    FISHES OF THE FRESHWATER POTOMAC Compiled by Jim Cummins, The Interstate Commission on the Potomac River Basin Always DRAFT - Version 02/21/2013 The following list of one-hundred and eighteen fish species known to be present in the freshwater portions of the Potomac River basin. Included, but not numbered, are fish that once were in the Potomac but are no longer are present; eight extirpated fish species (only one of which, the log perch, was perhaps a native to the Potomac) and three with uncertain presences. The list was originally (1995) compiled through a combination of personal field experience, a search of the literature, and input from regional fisheries biologists Ed Enamait (MD), Gerald Lewis (WV), Ed Stienkoenig (VA), and Jon Siemiens (DC). However, I attempt to keep the list updated when new information becomes available, thus the list is always draft. The distribution of these fishes within the Potomac is highly variable. Many are year-round residents and are fairly wide-spread, while some, such as the torrent shiner, are only found in very limited habitats/areas. Eleven are migratory species which typically come into the river system to spawn, and nine represent occasional visitors in freshwater-tidal areas. The native or introduced status of most of these species are generally accepted, but for some species this status is an object of continued researched and therefore caution should be used in interpreting this designation, especially when noted with a “?” mark. Of the 118 species currently found in the river, approximately 80 (68%) are considered native, 23 (19%) are considered introduced, and the rest (15, or 13%) are uncertain in origin.

E-mail: [email protected] Abstract Fishes of the genus Cottus have long been taxonomically challenging because of morphological similarities among species and their tendency to hybridize, and a number of undescribed species may remain in this genus. We used a combination of genetic and morphological methods to delineate and describe Cottus schitsuumsh, Cedar Sculpin, a new species, from the upper Columbia River basin, Idaho-Montana, USA. Although historically confused with the Shorthead Sculpin (C. confusus), the genetic distance between C. schitsuumsh and C. confusus (4.84–6.29%) suggests these species are distant relatives. Moreover, the two species can be differentiated on the basis of lateral-line pores on the caudal peduncle, head width, and interpelvic width. Cottus schitsuumsh is also distinct from all other Cottus in this region in having a single small, skin-covered, preopercular spine. Haplotypes of mtDNA cytochrome oxidase c subunit 1 of C. schitsuumsh differed from all other members of the genus at three positions, had interspecific genetic distances typical for congeneric fishes (1.61–2.74% to nearest neighbors), and were monophyletic in maximum-likelihood trees.
