We investigated the effect of short-term food restriction on metabolic thermogenesis of Chinese bulbuls (Pycnonotus sinensis) by measuring changes in body mass, body fat, basic metabolic rate (BMR), and organ mass of wild-caught Chinese bulbuls from Wenzhou, China. Short-term food restriction induced a significant decrease in body mass and body fat but body mass returned to normal levels soon after food was no longer restricted. Food restriction caused a significant reduction in BMR after 7 days (P<0.05), which returned to normal levels after food restriction ceased. Log total BMR was positively correlated with log body mass (r(2)=0.126, P<0.05). The dry masses of livers and the digestive tract were higher in birds that had been subject to temporary food restriction than in control birds and those subject to continual food restriction (P<0.001 and P<0.05, respectively). There was also significant differences in the dry mass of the lungs (P<0.05), heart (P<0.01), and spleen (P<0.05) in birds subject to short-term food restriction compared to control birds and those subject to continual food restriction. BMR was positively correlated with body and organ (heart, kidney and stomach) mass. These results suggest that the Chinese bulbul adjusts to restricted food availability by utilizing its energy reserves, lowering its BMR and changing the weight of various internal organs so as to balance total energy requirements. These may all be survival strategies that allow birds to cope with unpredictable variation in food abundance. </p>","PeriodicalId":88862,"journal":{"name":"Dong wu xue yan jiu = Zoological research","volume":"36 2","pages":"79-87"},"PeriodicalIF":0.0,"publicationDate":"2015-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4790253/pdf/ZoolRes-36-2-79.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33200463","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, several markers of oxidative stress and antioxidants activities were examined in brain, liver, kidneys, skeletal muscle and small intestine in non-lactating (Non-Lac) and lactating (Lac) KM mice. Uncoupling protein (ucps) gene expression was examined in brain, liver and muscle. During peak lactation, gross energy intake was 254% higher in Lac mice than in Non-Lac mice. Levels of H2O2 of Lac mice were 17.7% higher in brain (P<0.05), but 21.1% (P<0.01) and 14.5% (P<0.05) lower in liver and small intestine than that of Non-Lac mice. Malonadialdehyde (MDA) levels of Lac mice were significantly higher in brain, but lower in liver, kidneys, muscle and small intestine than that of Non-Lac mice. Activity of glutathione peroxidase (GSH-PX) was significantly decreased in brain and liver in the Lac group compared with that in the Non-Lac group. Total antioxidant capacity (T-AOC) activity of Lac mice was significantly higher in muscle, but lower in kidneys than Non-Lac mice. Ucp4 and ucp5 gene expression of brain was 394% and 577% higher in Lac mice than in Non-Lac mice. These findings suggest that KM mice show tissue-dependent changes in both oxidative stress and antioxidants. Activities of antioxidants may be regulated physiologically in response to the elevated ROS production in several tissues during peak lactation.

However, in habitats with sympatric similarly sized carnivores, misidentification of scats is frequent and can lead to bias in research results. To address the scat identification dilemma, molecular scatology techniques have been developed to extract DNA from the donor cells present on the outer lining of the scat samples. A total of 100 samples were collected in the winter of 2009 and 2011 in Taxkorgan region of Xinjiang, China. DNA was extracted successfully from 88% of samples and genetic species identification showed that more than half the scats identified in the field as snow leopard (Panthera uncia) actually belonged to fox (Vulpes vulpes). Correlation between scat characteristics and species were investigated, showing that diameter and dry weight of the scat were significantly different between the species. However it was not possible to define a precise range of values for each species because of extensive overlap between the morphological values. This preliminary study confirms that identification of snow leopard feces in the field is misleading. Research that relies upon scat samples to assess distribution or diet of the snow leopard should therefore employ molecular scatology techniques. These methods are financially accessible and employ relatively simple laboratory procedures that can give an indisputable response to species identification from scats. </p>","PeriodicalId":88862,"journal":{"name":"Dong wu xue yan jiu = Zoological research","volume":"36 2","pages":"72-8"},"PeriodicalIF":0.0,"publicationDate":"2015-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.13918/j.issn.2095-8137.2015.2.72","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33200462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As one of the few ecological laws, the SAR plays a vital role in the design and assessment of biodiversity protection regions (Lomolino et al, 2010; Ladle & Whittaker, 2011). \u0000 \u0000Increasing area and habitat promote species richness (Triantis et al, 2003) and both these mechanisms have theoretical support. Basically, the notion of area per se claims that the effects of area are embodied in the chance of species extinction (Preston, 1960, 1962; MacArthur & Wilson, 1963, 1967). In contrast, the habitat diversity hypothesis states that the highly diversified habitats often found in large patches positively impact species addition (Williams, 1964). Although it remains controversial which mechanism is more important in influencing species richness, some ecologists believe that the area per se and habitat diversity are mutually complementary and not mutually exclusive (Triantis et al, 2003). \u0000 \u0000Land-bridge islands are characterized by well-delineated boundaries, an inhospitable surrounding matrix and relatively homogeneous habitats (Hu et al, 2011). Land-bridge islands are considered excellent models for studying the relationship between area per se and habitat diversity. Located in Chun’an County in Zhejiang, eastern China (N29o22′-29o50′, E118o34′-119o15′), Thousand Island Lake is a large man-made lake following dam construction on the Xin’an River in 1959. With a water surface area of approximately 580 km2, the lake contains 1 078 land-bridge islands larger than 0.25 ha (108 m in water level elevation). \u0000 \u0000To understand correlations between area per se and habitat diversity we used bird data for 41 land-bridge islands in Thousand Island Lake from 2006 to 2009. This data was used to compare the goodness-of-fit of the classical Arrhenius SAR model, and the choros (K) model integrating both area and habitats (Triantis et al, 2003). The canonical power function model (logS=logc× z×logA, in which S represents the number of species and A is the size of the area; c and z are constants) was used to investigate the effect of area on bird species richness. Choros (K) (K=H×A, in which H represents habitat diversity and A is the area of the study island) was adopted to assess correlations between area and habitat diversity (Zhang et al, 2008; Wang et al, 2010). The classical SAR model can be expressed as: \u0000 \u0000Log (S)=log (c)+z log (A) (1) \u0000 \u0000and the K model can be expressed as: \u0000 \u0000Log (S)=log (c)+z log (K) (2) \u0000 \u0000Akaike Information Criterion (AIC) was used to determine the optimum model and the model with the lowest AICc (modification of AIC for small n) was considered better (Burnham & Anderson, 2002).
