We developed an additive model to estimate seasonal energy expenditure of nonreproductive, free-ranging Iberian lynx (Felis pardina) at Donana National Park in southwestern Spain. We considered only resting, locomotion, hunting, and eating costs. Data for the model were provided by radiomonitoring an adult male (15.4 kg) and an adult female (9.95 kg) in 24-hour samples (n=53) between 1983 and 1985. Average daily energy expenditure was 912 kcal for the male and 673 kcal for the female, with greater seasonal ...

Data are presented on mortality rates of the Iberian lynx Felis pardina in Doñana National Park and the surrounding area in southwestern Spain, collected from 1983 to 1989. Data from radio-tagged lynxes and records of lynx mortality were used to assess causes of death. Annual mortality rate, estimated by using the Heisey and Fuller methodology, was 0·37. Human activities were the main cause of lynx mortality in this mainly fully protected area, either directly (illegal trapping: 41·7%; road traffic: ...

A combination of the dissociative anesthetic ketamine hydrochloride (KH) and the sedative xylazine hydrochloride (XH) was used to immobilize 31 wild Iberian lynx (Felis pardina) 45 times at Doñana National Park, Spain. A mean (±SE) dose of 4.6 (±0.2) mg/kg KH and 4.0 (±0.2) mg/kg XH resulted in mean (±SE) induction time of 5.6 (±0.3) min and mean (±SE) first reaction time of 59.3 (±6.5) min. Convulsions occurred four times (9%), but with no noteworthy consequences.

For some years now, the scientific community has been studying how videogames foster acquisition of mental representations of the world around us. Research to date suggests that the efficiency of videogames as learning tools largely depends on the instructional design in which they are included. This article provides empirical evidence related to the use of the videogame Angry Birds and how it can modify students’ conceptions regarding object motion.

Ischemia-modified albumin (IMA), measured with the albumin cobalt binding test, is a marker of myocardial ischemia. We measured IMA concentrations after elective direct-current cardioversion for atrial fibrillation to determine whether transient myocardial ischemia occurs. Patients with electrocardiographic changes after cardioversion (ST-depression and/or T-wave inversion) had significantly higher IMA levels than those without these changes. Thus, elevated levels of IMA after cardioversion may reflect ...

Home range size and activity pattern were evaluated by radiotracking for seven red fox Vulpes vulpes (Linnaeus, 1758) breeding females, in the Doñana Biological Reserve, SW Spain. Mean home range size was 218 ha (SD = 76, n = 7). A home range for one of the seven females was 1129 ha for one nearly complete year and only 253 ha for the same female during the breeding season. Authors suggest that size reduction could be a result of energetical and behavioral shifts due to the breeding condition. Activity ...

Most reported cases were in people who had high CD4 cell counts and similar outcomes to those without HIV. Emerging data suggest worse clinical outcomes and higher mortality in people with more advanced HIV. We describe the clinical characteristics and outcomes of mpox in a cohort of people with HIV and low CD4 cell counts (CD4 <350 cells per mm3).MethodsA network of clinicians from ...
