ISSN 1989‐8649 Manag. Biolog. Invasions, 2010, 1 Abstract Non‐Native freshwater fish management in Biosphere Reserves The consideration of non‐native freshwater fish species in the Andrea PINO‐DEL‐CARPIO*, Rafael MIRANDA & Jordi PUIG management plans of 18 Biosphere Reserves is evaluated. Additionally, impacts caused by introduced freshwater fish species are described.

Selection, Constraint, and Adaptation in the Visual Genes of Neotropical Cichlid Fishes and Other Vertebrates
SELECTION, CONSTRAINT, AND ADAPTATION IN THE VISUAL GENES OF NEOTROPICAL CICHLID FISHES AND OTHER VERTEBRATES by Frances Elisabeth Hauser A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Ecology and Evolutionary Biology University of Toronto © Copyright by Frances E. Hauser 2018 SELECTION, CONSTRAINT, AND ADAPTATION IN THE VISUAL GENES OF NEOTROPICAL CICHLID FISHES AND OTHER VERTEBRATES Frances E. Hauser Doctor of Philosophy, 2018 Department of Ecology and Evolutionary Biology University of Toronto 2018 ABSTRACT The visual system serves as a direct interface between an organism and its environment. Studies of the molecular components of the visual transduction cascade, in particular visual pigments, offer an important window into the relationship between genetic variation and organismal fitness. In this thesis, I use molecular evolutionary models as well as protein modeling and experimental characterization to assess the role of variable evolutionary rates on visual protein function. In Chapter 2, I review recent work on the ecological and evolutionary forces giving rise to the impressive variety of adaptations found in visual pigments. In Chapter 3, I use interspecific vertebrate and mammalian datasets of two visual genes (RH1 or rhodopsin, and RPE65, a retinoid isomerase) to assess different methods for estimating evolutionary rate across proteins and the reliability of inferring evolutionary conservation at individual amino acid sites, with a particular emphasis on sites implicated in impaired protein function. ii In Chapters 4, and 5, I narrow my focus to devote particular attention to visual pigments in Neotropical cichlids, a highly diverse clade of fishes distributed across South and Central America. -

Personality, Habitat Selection and Territoriality Kathleen Church A
Habitat Complexity and Behaviour: Personality, Habitat Selection and Territoriality Kathleen Church A Thesis In the Department of Biology Presented in Partial Fulfilment of the Requirements For the Degree of Doctor of Philosophy (Biology) at Concordia University Montréal, Québec, Canada July 2018 © Kathleen Church, 2018 iii Abstract Habitat complexity and behaviour: personality, habitat selection and territoriality Kathleen Church, Ph.D. Concordia University, 2018 Structurally complex habitats support high species diversity and promote ecosystem health and stability, however anthropogenic activity is causing natural forms of complexity to rapidly diminish. At the population level, reductions in complexity negatively affect densities of territorial species, as increased visual distance increases the territory size of individuals. Individual behaviour, including aggression, activity and boldness, is also altered by complexity, due to plastic behavioural responses to complexity, habitat selection by particular personality types, or both processes occurring simultaneously. This thesis explores the behavioural effects of habitat complexity in four chapters. The first chapter, a laboratory experiment based on the ideal free distribution, observes how convict cichlids (Amatitlania nigrofasciata) trade-off the higher foraging success obtainable in open habitats with the greater safety provided in complex habitats under overt predation threat. Dominants always preferred the complex habitat, forming ideal despotic distributions, while subordinates altered their habitat use in response to predation. The second chapter also employs the ideal free distribution to assess how convict cichlids within a dominance hierarchy trade-off between food monopolization and safety in the absence of a iv predator. Dominants again formed ideal despotic distributions in the complex habitat, while dominants with lower energetic states more strongly preferred the complex habitat. -
They're Not Just Convicts Anymore
2008 FAAS Publication Awards. Please follow reprint instructions at http://www.faas.info/2008_publication_awards_winners.html#reprintpolicy They’re Not Just Convicts Anymore By Daniel Spielman All Photos by Daniel Spielman Introduction Convicts get no respect, with many a cichlidophile turning up his or her nose at the sight of a group on Convicts in a tank or a bag of fry in an auction. It’s time for that to change. Easy to breed and exhibiting wonderful parental care, Convict cichlids (Cryptoheros nigrofasciatus) have long been staples in the hobby. Indeed, for many new fishkeepers, the satisfaction of watching a pair of Convict parents herd a group of fry around a tank sparks the initial desire to keep other mem bers of the cichlid family. Indeed, my fish cichlids were Convicts, and watch ing them care for their fry definitely got me hooked. The contrast with trying to keep guppies or swordtails from eating their own offspring is striking (how did eating one’s own young ever evolve in the first place?). However, the very fact that Convicts spawn so readily in the aquarium causes many hobbyists to quickly lose interest in the species. Although Convicts occasionally appear on experienced hobbyists’ lists of most favorite cichlid, the problem is they are just too common and too easy to breed. Typical Convict spawning jokes involve two fish and a wet paper towel, and one often feels fortunate to break the $1 barrier at the auction to avoid the indignity of having to bring one’s fish back home again at the end of the monthly club meeting. -

Rapid Evolution and Selection Inferred from the Transcriptomes of Sympatric Crater Lake Cichlid Fishes
Rapid evolution and selection inferred from the transcriptomes of sympatric crater lake cichlid fishes K. R. ELMER, S. FAN, H. M. GUNTER, J. C. JONES, S. BOEKHOFF, S. KURAKU and A. MEYER Lehrstuhl fUr Zoologie und Evolutionsbiologie, Department of Biology, University of Konstanz, Universitiitstrasse 10, 78457 Konstanz, Germany Abstract Crater lakes provide a natural laboratory to study speciation of cichlid fishes by ecological divergence. Up to now, there has been a dearth of transcriptomic and genomic information that would aid in understanding the molecular basis of the phenotypic differentiation between young species. We used next-generation sequencing (Roche 454 massively parallel pyrosequencing) to characterize the diversity of expressed sequence tags between ecologically divergent, endemic and sympatric species of cichlid fishes from crater lake Apoyo, Nicaragua: benthic Amphilophus astorquii and limnetic Amphilophus zaliosus. We obtained 24174 A. astorquii and 21382 A. zaliosus high quality expressed sequence tag contigs, of which 13 106 pairs are orthologous between species. Based on the ratio of non synonymous to synonymous substitutions, we identified six sequences exhibiting signals of strong diversifying selection (KalKs > 1). These included genes involved in biosynthesis, metabolic processes and development. This transcriptome sequence variation may be reflective of natural selection acting on the genomes of these young, sympatric sister species. Based on Ks ratios and p-distances between 3'-untranslated regions (UTRs) calibrated to previously published species divergence times, we estimated a neutral transcriptome-wide substitutional mutation rate of ~1.25 x 10-6 per site per year. We conclude that next-generation sequencing technologies allow us to infer natural selection acting to diversify the genomes of young species, such as crater lake cichlids, with much greater scope than previously possible. -

OTTONI Laboratório de Ictiologia Geral e Aplicada, Departamento de Zoologia, Universidade Federal do Rio de Janeiro Cidade Universitária, CEP 21994-970, Caixa Postal 68049, Rio de Janeiro, RJ, Brazil fpottoni(at)yahoo.com.br Received on November 13, 2009, accepted on February 14, 2010. Published online at www.vertebrate-zoology.de on May 12, 2010. > Abstract Australoheros capixaba, new species, is distributed along the rio Itaúnas, rio Barra Seca, rio São Mateus and the lower rio Doce basins. The new species is distinguished from its congeners in the rio Paraná-Uruguay system and Laguna dos Patos system by having 12 caudal vertebrae (vs. 13 – 15). Australoheros capixaba differs from the other species of Australoheros from south-eastern Brazil by its coloration in life (a reddish chest, large spots on the dorsal region of the trunk and a green iridescence on the pelvic fi ns). It also differs from some of its congeners by having a longer caudal peduncle, a longer anal- fi n spine, fewer dorsal-fi n spines and fewer anal-fi n rays. Australoheros capixaba sp. n. is the fi rst species from the genus described for the Estado do Espírito Santo, south-eastern Brazil. The phylogenetic placement of the species in the genus cannot be discussed, because there is no phylogenetic work about the Australoheros species from south-eastern Brazil. > Resumo Australoheros capixaba, nova espécie, se distribui ao longo das bacias do rio Itaúnas, rio Barra Seca, rio São Mateus e baixo rio Doce.
