Cyprinidae; Misgurnus anguillicaudatus; body size; diploidy; females; fish; growth performance; habitats; longevity; males; sex ratio; tetraploidy; watersheds; China; Yangtze River
Abstract:
... Diploids and tetraploids of the cyprinid loach Misgurnus anguillicaudatus coexist in many natural habitats in Asia. However, little is known about the biological and ecological differences between these two ploidy forms. We examined age, body size and growth rates of fish in a mixed ploidy population of M. anguillicaudatus in the Yangtze River basin in China. The sex ratios of both diploid and tet ...

Cyprinidae; allometry; anthropogenic activities; aquatic habitat; body size; fecundity; females; fish; habitat destruction; hydrology; lentic systems; lotic systems; males
Abstract:
... BACKGROUND: Aquatic habitats have been altered over the past century due to a variety of anthropogenic influences. Ecomorphology is an area of aquatic ecology that can both directly and indirectly assess the effects of habitat alterations on organisms. However, few studies have explored long term trends in morphological variation. Long term changes in morphology can potentially impact niche and ul ...

3. Evolution of mating systems and sexual size dimorphism in North American cyprinids

Behavioral ecology and sociobiology 2013 v.67 no.5 pp. 747-756
ISSN:

Subject:
Cyprinidae; body size; dimorphism; females; fish; males; mating systems; models; phylogeny; spawning; sperm competition; testes
Abstract:
... Mating systems evolve with sexual size dimorphism (SSD) in many animals. Mating systems with males larger than females occur when males compete for female access or guard territories, while mating systems with group mating tend to occur in species where females are the same size or larger than males. In addition to variation in SSD with mating system, sperm competition varies among mating systems ...

Cyprinidae; age determination; animal growth; body size; eggs; fecundity; females; fish; gender differences; gonadosomatic index; life history; males; sexual dimorphism; spatial variation; streams; watersheds; China
Abstract:
... Life-history traits of Acrossocheilus fasciatus were examined using 384 specimens collected monthly during May 2009 and April 2010 in the Huishui Stream of the Qingyi watershed, China. Using scales for age determination, female and male fish comprised five and four age groups, respectively. The monthly changes in marginal increment ratio suggested that annuli on scales were formed during March thr ...
