Growth deceleration coefficients were shown to vary widely and differ significantly among individuals. The average value of the growth deceleration coefficient for the population is 0.060. The growth of mussels in the Livojoki River is accompanied by two regular biorhythms. These biorhythm periods were roughly constant both through an individual’s ontogeny and among mussels, their average periods were 7.16 and 4.09 years. We discuss the possibility that these biorhythms are of thermodynamic nature.

En total, achéganse nomes galegos para 534 especies de moluscos. A estrutura En primeiro lugar preséntase unha clasificación taxonómica que considera as clases, ordes, superfamilias e familias de moluscos. Aquí apúntase, de maneira xeral, os nomes dos moluscos que hai en cada familia. A seguir vén o corpo do documento, onde se indica, especie por especie, alén do nome científico, os nomes galegos e ingleses de cada molusco (nalgún caso, tamén, o nome xenérico para un grupo deles).

Alén diso, inclúense algunhas fontes básicas a respecto da metodoloxía e dos criterios terminolóxicos empregados. 2 Tratamento terminolóxico De modo moi resumido, traballouse nas seguintes liñas e cos seguintes criterios: En primeiro lugar, aprofundouse no acervo lingüístico galego. A respecto dos nomes dos moluscos, a lingua galega é riquísima e dispomos dunha chea de nomes, tanto específicos (que designan un único animal) como xenéricos (que designan varios animais parecidos). -
Conservation Officer's Report 2013
Conservation Officer’s Report 2013 ADVICE & HELP: 1. Roman snails: Numerous assistance requests were dealt with concerning Helix pomatia the Roman snail. These included: Assistance with or confirmation of correct Roman snail identification; Advice on survey options and guidance and help for those engaged in conservation work to obtain Natural England licences (H. pomatia is protected under Schedule 5 of the Wildlife & Countryside Act). Suggestions to explain the sudden deaths of Roman snails including for a North Downs population where mortality was noted as to occurring between dawn and dusk. Various suggestions were made for this unusual observation including one from David Heaver of Natural England who suggested, “I would not discount sciomyzids - the adult flies parasitise adult snails and the larvae develop within either the mantle or body of the snail. When the grown larvae leave the snail to pupate, which the evidence often suggests may be overnight, the snail succumbs and will be found in the morning, the larvae having moved off and pupated in litter”. 2. Identification issues: A number of conservation linked identification issues were undertaken. These included clarification of two incorrect identifications of Pisidium tenuilineatum from different parts of Sussex, confusion arising from separation of Valvata piscinalis and V. macrostoma, and several incidents where help was needed to identify large unionid mussels with certainty. ROMAN SNAILS THREATENED BY DEVELOPMENT PLAN: A long and sometimes acrimonious planning dispute had been running for at least nine years between some residents of Harpenden, Hertfordshire and Harpenden Town Council (HTC). This concerns a relatively small area of former allotments and adjacent Westfield Recreation Ground known both to local residents and the council to support a population of Roman snails Helix pomatia. -
Age Influences Resistance to Infestation by Freshwater Pearl Mussel (Margaritifera Margaritifera)Glochidia

Stoeckle3 & Ralph Kuehn4,5 & Per Johan Jakobsen1 Received: 30 October 2018 /Accepted: 20 March 2019 /Published online: 1 April 2019 # Springer-Verlag GmbH Germany, part of Springer Nature 2019 Abstract The freshwater pearl mussel (Margaritifera margaritifera) is an endangered bivalve with an obligate parasitic stage on salmonids. Host suitability studies have shown that glochidial growth and load vary significantly between host strains as well as among individuals of a suitable strain. Variation in host suitability has been linked to environmental conditions, host age and/or size, genetic composition of the host and parasite, or a combination of these factors. In our study, we wanted to investigate if brown trout (Salmo trutta) displayed an age-dependent response to glochidial infestation. We hypothesised that 1+ naive brown trout hosts tolerate glochidial infestation better than 0+ hosts. In order to test our hypothesis, we infested 0+ and 1+ hatchery reared brown trout with glochidia from closely related mothers and kept them under common garden conditions. This allowed us to observe a pure age dependent host response to infestation, as we eliminated the confounding effect of genotype-specific host interactions. We analysed the interaction between glochidial load and host condition, weight and length, and observed a signif- icant age-dependent relationship. Glochidial load was negatively correlated to host condition in 0+ fish hosts and positively correlated in 1+ hosts. -

Takahashi and Makoto Osada Additional information is available at the end of the chapter http://dx.doi.org/10.5772/intechopen.69165 Abstract It has been observed that 5-HT excites the heart nerves in hard clam and regulates con- traction and relaxation of the anterior byssus retractor muscle in the blue mussel. It is now known that 5-HT regulates several neurobehavioral systems such as mood, appetite, sleep, learning, and memory. It also plays critical roles in the physiological functions of peripheral organs involved in stress, growth, and reproduction in the animal kingdom. The present study reviews conserved 5-HT biosynthesis and its localization in the ner- vous system, and its physiological contribution to regulate reproduction in bivalves. In the cytosol of neurons, tryptophan hydroxylase catalyzes hydroxylation of l-tryptophan to 5-hydroxytryptophan, which is converted to 5-HT by aromatic l-amino acid decarbox- ylase. A 5-HT transporter and a monoamine oxidase reuptakes and metabolizes 5-HT to control the amount of released 5-HT in the nervous system and peripheral organs. -
Population Genetics of a Common Freshwater Mussel, Amblema Plicata, in a Southern U.S
Freshwater Mollusk Biology and Conservation 23:124–133, 2020 Ó Freshwater Mollusk Conservation Society 2020 REGULAR ARTICLE POPULATION GENETICS OF A COMMON FRESHWATER MUSSEL, AMBLEMA PLICATA, IN A SOUTHERN U.S. RIVER Patrick J. Olson*1 and Caryn C. Vaughn1 1 Department of Biology and Oklahoma Biological Survey, University of Oklahoma, Norman, OK 73019 ABSTRACT Myriad anthropogenic factors have led to substantial declines in North America’s freshwater mussel populations over the last century. A greater understanding of mussel dispersal abilities, genetic structure, and effective population sizes is imperative to improve conservation strategies. This study used microsatellites to investigate genetic structure among mussel beds and estimate effective population sizes of a common North American mussel species, Amblema plicata, in the Little River, Oklahoma. We used five microsatellite loci to genotype 270 individuals from nine mussel beds distributed throughout the river and one of its tributaries, the Glover River. Our results indicate that subpopulations of A. plicata in the Little River are genetically similar. Upstream subpopulations had less genetic diversity than sites located downstream of the confluence of the Glover and Little rivers. Downstream subpopulations were primarily assigned to the same genetic group as upstream subpopulations, but they were admixed with a second genetic group. Low flows during droughts likely influenced the observed genetic structuring in A. plicata populations in the Little River. Additionally, downstream subpopulations may be admixed with a genetically distinct population of A. plicata, which may account for the increased genetic diversity. Estimates of effective population sizes (Ne) of large mussel beds were low compared to the total abundance (N)ofA. -
