Camouflaged or tanned: plasticity in freshwater snail pigmentation [PDF]
Biology Letters, 2013 By having phenotypically plastic traits, many organisms optimize their fitness in response to fluctuating threats. Freshwater snails with translucent shells, e.g. snails from the Radix genus, differ considerably in their mantle pigmentation patterns, with snails from the same water body ranging from being completely

PLoS ONE, 2021 The management of ecosystem has been a major contributor to the control of diseases that are transmitted by snail intermediate hosts. The ability of freshwater snails to self-fertilize, giving rise to thousands of hatchlings, enables them to contribute ...

Evidence for adaptive explanations of semelparity in animals
Biological Reviews, EarlyView.ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

The freshwater prosobranch snails fagotia in Turkey
, 2009 Tatlısı Prosobranch türü Fagotia’nın Türkiye’de günümüzde yaşayan üç türü vardır. Bunlardan iki tanesi pontian kökenlidir. Bir türü ise Anadolu kara parrçası için endemic olduğu düşünülüyor. Pleistosende maydana gelen jeolojik gelişmelere gore göç yolları açıklanmaya çalışılmış ve diğer pontian türlerle bağlantıları ortaya ...

Developmental Dynamics, EarlyView.Abstract The sea anemone, Nematostella vectensis, has been used as a model organism in developmental biology studies for many years. This estuarine species has the notable capacity to regenerate its full body plan from small pieces throughout life. Nematostella have been described as having a great degree of cellular plasticity.

Ecography, EarlyView.Despite the growing number of studies on trophic networks in recent decades, there are still important gaps in our understanding of how these networks are structured across broad environmental gradients. These gaps are even greater in some groups of terrestrial vertebrates, such as snakes, requiring a cohesive synthesis of their broader trophic ...

Food Chemistry International, EarlyView.Natural actomyosin from B. bengalensis exhibited maximum solubility (∼69.9%) at 40°C and stability near neutral pH, with minimum solubility at pH 4. Surface hydrophobicity and emulsifying activity peaked at 50°C, whereas Ca2+‐ATPase and foaming peaked at 40°C. DSC and SDS–PAGE confirmed denaturation above 40°C.

Phylogeny of freshwater viviparid snails in Japan [PDF]
Journal of Molluscan Studies, 2015 We document extensive incongruence between molecular phylogeny and the current taxonomy of the freshwater gastropod family Viviparidae in Japan. A phylogeny based on the mitochondrial cytochrome oxidase subunit I and 16S rRNA genes for East Asian viviparids comprises three major clades, the two largest of which are composed primarily of paraphyletic or
