1Landscape features and weather influence nest survival of a ground-nesting bird of conservation concern,the greater sage-grouse,in humanaltered environments显示文摘Introduction:Ground-nesting birds experience high levels of nest predation.However,birds can make selection decisions related to nest site location and characteristics that may result in physical,visual,and olfactory impediments to predators.Methods:We studied daily survival rate[DSR]of greater sage-grouse(Centrocercus urophasianus)from 2008 to 2010 in an area in Wyoming experiencing large-scale alterations to the landscape.We used generalized linear mixed models to model fixed and random effects,and a correlation within nesting attempts,individual birds,and years.Results:Predation of the nest was the most common source of nest failure(84.7%)followed by direct predation of the female(13.6%).Generally,landscape variables at the nest site(≤30 m)were more influential on DSR of nests than features at larger spatial scales.Percentage of shrub canopy cover at the nest site(15-m scale)and distances to natural gas wells and mesic areas had a positive relationship with DSR of nests,whereas distance to roads had a negative relationship with DSR of nests.When added to the vegetation model,maximum wind speed on the day of nest failure and a 1-day lag in precipitation(i.e.,precipitation the day before failure)improved model fit whereby both variables negatively influenced DSR of nests.Conclusions:Nest site characteristics that reduce visibility(i.e.,shrub canopy cover)have the potential to reduce depredation,whereas anthropogenic(i.e.,distance to wells)and mesic landscape features appear to facilitate depredation.Last,predators may be more efficient at locating nests under certain weather conditions(i.e.,high winds and moisture).Stephen L Webb Chad V Olson Matthew R Dzialak Seth M Harju Jeffrey B Winstead Dusty Lockman 2012Ecological Processes2012,1,1:2
2Age at diagnosis of type 2 diabetes and cardiovascular risk factor profile:A pooled analysis显示文摘BACKGROUND The diagnosis of type 2 diabetes(T2D)in younger adults,an increasingly common public health issue,is associated with a higher risk of cardiovascular complications and mortality,which may be due to a more adverse cardiovascular risk profile in individuals diagnosed at a younger age.AIM To investigate the association between age at diagnosis and the cardiovascular risk profile in adults with T2D.METHODS A pooled dataset was used,comprised of data from five previous studies of adults with T2D,including 1409 participants of whom 196 were diagnosed with T2D under the age of 40 years.Anthropometric and blood biomarker measurements included body weight,body mass index(BMI),waist circumference,body fat percentage,glycaemic control(HbA1c),lipid profile and blood pressure.Univariable and multivariable linear regression models,adjusted for diabetes duration,sex,ethnicity and smoking status,were used to investigate the association between age at diagnosis and each cardiovascular risk factor.RESULTS A higher proportion of participants diagnosed with T2D under the age of 40 were female,current smokers and treated with glucose-lowering medications,compared to participants diagnosed later in life.Participants diagnosed with T2D under the age of 40 also had higher body weight,BMI,waist circumference and body fat percentage,in addition to a more adverse lipid profile,compared to participants diagnosed at an older age.Modelling results showed that each one year reduction in age at diagnosis was significantly associated with 0.67 kg higher body weight[95%confidence interval(CI):0.52-0.82 kg],0.18 kg/m^(2) higher BMI(95%CI:0.10-0.25)and 0.32 cm higher waist circumference(95%CI:0.14-0.49),after adjustment for duration of diabetes and other confounders.Younger age at diagnosis was also significantly associated with higher HbA1c,total cholesterol,low-density lipoprotein cholesterol and triglycerides.CONCLUSION The diagnosis of T2D earlier in life is associated with a worse cardiovascular risk factor profile,compared to those diagnosed later in life.Mary M Barker Francesco Zaccardi Emer M Brady Gaurav S Gulsin Andrew P Hall Joseph Henson Zin ZinHtike Kamlesh Khunti Gerald P McCann Emma L Redman David R Webb Emma G Wilmot Tom Yates Jian Yeo Melanie J Davies Jack A Sargeant 2022World Journal of Diabetes2022,13,3:2
