This paper describes and discusses the impacts of the passage of cold fronts on the vertical structure of the Carlos Botelho (Lobo-Broa) Reservoir as demonstrated by changes in physical, chemical, and biological variables. The data were obtained with a continuous system measuring 9 variables in vertical profiles in the deepest point of the reservoir (12 m) coupled with climatological informatio...

Giraffe populations in East Africa have declined in the past thirty years yet there has been limited research on this species. This study had four objectives: i) to provide a baseline population assessment for the two largest populations of Rothschild's giraffes in Kenya, ii) to assess whether there are differences in population structure between the two enclosed populations, iii) to assess the...

Two new species of Dolichothele Mello-Leitão, 1923 are described from Brazil and Bolivia, D. mottaisp. n. from Distrito Federal and the state of Goiás, Brazil, and D. camargorumsp. n. from the state of Rondônia, Brazil, and the La Paz region, Bolivia. Males of the two new species resemble Dolichothele bolivianum (Vol, 2001) in having a small subapical keel on the distal embolus and females in p...

This article summarises the work being undertaken by the World Health Organisation Pacific Islands Mental Health Network (PIMHnet) since its inception in 2006. The article also outlines the mental health issues that present particular challenges in the Pacific region, and the innovative approaches that have been taken to address those issues, with the goal of improving mental health throughout ...

OBJECTIVE Prospective studies have linked negative affect with hypertension, cardiovascular disease, and mortality. This study aims to identify if cardiovascular activity in day-to-day settings is related to affect levels as assessed using the Day Reconstruction Method (Kahneman, Krueger, Schkade, Schwarz, & Stone, 2004). DESIGN 186 people underwent baseline physiological testing and were mon...
