Abstract The western sand lance ( Ammodytes japonicus ) is a valuable fishery resource in the Seto Inland Sea. Although it survives through summer by estivating, faces threat of population decline as seawater temperature increases at an alarming rate due to climate change. We applied data from meta-analyses and laboratory analyses inform climate-linked model predicted survival determine impact change on persistence A. end century. Our results suggest that mortality during estivation with...
1. Communities of different species are often structured according to niche differentiation associated with competitive interactions. We show that similar principles may apply on an ecological time-scale when individuals a having wide size variation compete for resources, using the Lake Tanganyika cichlid Lobochilotes labiatus (5-30 cm). This has mouth especially adapted suck up invertebrates from rock crevices. 2. Individuals defended feeding territories against similar-sized conspecifics,...
Theories suggest that, in cooperatively breeding species, female control over paternity and reproductive output may affect male skew group stability. Female come about through cryptic choice or behaviour, but experimental studies are scarce. Here, we show a new form of polyandrous cichlid fish ( Julidochromis transcriptus ), which females prefer wedge-shaped nesting sites. Wedge-shaped sites allowed to manipulate the siring success member males by spawning clutch at spot where large were...

Abstract The effect of group size on reproductive success has long been studied in cooperatively breeding species, as it might provide an adaptive explanation for group‐living social species. Numerous studies have shown positive effects subordinates (‘helper effect’), but these also revealed the importance controlling statistically, or experimentally, other factors that affect success. Here, we first examine relationships between size, body members and nest cichlid Julidochromis ornatus ,...
Abstract A good understanding of how migratory animals use their habitat network is expected to provide important insights for the prediction population dynamics at both local and regional scales. We focused on physical structure a could affect fish migration between Lake Biwa its tributary lagoons. Although lagoons suitable breeding nursery grounds native fishes, it matter concern that they can also be hotbed invasive exotic fishes. Here, we assessed patterns crucian carps ( Carassius spp.)...
The plasticity of the sex roles in blenniid fish Petroscirtes breviceps , a nest brooder with exclusive paternal care, was studied throughout an 8 month breeding season. Males performed most courtships early and late season, whereas females middle These results indicated that individuals initiating courtship changed seasonally, role reversal Intrasexual aggression both sexes occurred much more frequently mid‐season than seasons. fought when available sites were limited, regardless presence...
Abstract Rice fields serve as alternative habitats for wetland species, and their recent reduction in area due to land conversion is considered one of the main human drivers biodiversity loss. Even existing rice fields, physico‐chemical disturbances, such farmland consolidation agrochemical application, also have negative effects on biodiversity. For fish that inhabit at least part life history, differences water level between irrigation ditches caused by system improvements are critical...
瀬戸内海燧灘周辺海域におけるタチウオの食性について,2011年から2013年にかけての各月標本採集により調査した。確認された餌生物のうち,カタクチイワシ,イカナゴ,ソコシラエビの餌生物重要度指数(%IRI)がそれぞれ10%以上と高い値を示した。カタクチイワシとソコシラエビはほぼ周年,イカナゴは3-4月に多く出現した。タチウオの成長に伴い,魚類の重要度は増加し,甲殻類では低下した。タチウオによるイカナゴの高頻度での利用は,本海域の特徴であると考えられた。
Ten novel microsatellite markers were developed for the western sand lance, Ammodytes japonicus, which has decreased significantly in many fishing grounds because of overexploitation and deterioration its habitat. The 10 successfully amplified two sets multiplex polymerase chain reactions (PCR). A total 63 individuals collected successive years from a single population used to assess characteristics markers. number alleles per locus ranged seven 24 with observed heterozygosity ranging 0.397...
