The acute toxicity of endocrine disrupters in two crustaceans, Americamysis bahia (A. bahia) and Daphnia magna (D. magna), was investigated the toxicological responses compared. Bisphenol A had lowest to D. magna, 48 hr median lethal concentrations (LC50) values 12.8 mg/l. However, toxic sensitivity A. bisphenol approximately 10-fold higher than for (48 LC50; 1.34 mg/l). LC50 estradiol-17β 2.97 1.69 mg/l bahia, respectively. Nonylphenol highest against both 0.051 mg/l) 0.18 ecdysteroids,...
Abstract Aim Natural disaster risk reduction (DRR) is becoming a more important function of protected area (PAs) for current and future global warming. However, biodiversity conservation DRR have been handled separately their interrelationship has not explicitly addressed. This mainly because, due prevailing strategies criteria PA placement, large proportion PAs are currently located far from human‐occupied areas, habitats in areas largely ignored as potential sites despite high...
Ecological information on the golden venus chub (Hemigrammocypris rasborella Fowler, 1910) was collected during field surveys and used to analyze habitat use by this species at each growth stage. Surveys were conducted every month for approximately 2 years in an irrigation ditch near Ushizu River, Kyushu Island, Japan. Based characteristic nuptial coloration of males, it estimated that H. spawns between spring summer. Size measurements 2697 individuals indicated two size classes. The...
In Japan, Pseudorasbora parva has not been negatively affected by artificial changes in its habitat. Ecological traits of the species may explain this easy adaptation to habitats. An ecological investigation P. inhabiting irrigation ditches was conducted monthly for approximately two years on northwestern Kyushu Island, Japan. Measurements 1927 individuals revealed size classes, maturation age (1 year), and lifespan (1–2 years). Results study previous studies show that exhibits life history...
The presence and populations of freshwater fishes the revetment conditions in creeks were investigated at 48 sampling sites around Sea Ariake northwestern Kyushu, Japan. Each creek studied this survey was classified into one three following types terms conditions: Type-1, have earthen revetments except when crossing roads; Type-2, although there are concrete creeks, these short, agricultural water flows over reaches bank vegetations or banks during off-season; Type-3, high does not flow any...
This study presents the complete mitochondrial genome sequence of Gammarus nipponensis, a freshwater crustacean found in western regions Honshu, Shikoku and Kyushu Japan. The entire is 16,429 bp length, encoding standard set 13 protein-coding genes, two ribosomal RNA genes 22 transfer as well putative control regions. G. nipponensis characterized by high concentration A T nucleotides (67.1%). Notably, mitogenome contains long TATTTTA repeats region 2 at 686 long. newly available information...
Opsariichthys uncirostris was introduced from Lake Biwa to several freshwater areas in Kyusyu Island, and the gut contents of this fish were observed order evaluate effect internal invasion on native aquatic organisms. The specimens captured Futatsugawa river, north- western Kyushu Japan, between February 2007 January 2008, their examined under a stereomicroscope. exotic species comprised various prey ani- mals, mainly fishes most seasons. empty ratio approximately 80% seasons 100% during...
