BACKGROUND In Lithuania, suicides are a grave public health problem, requiring more extensive investigation. The aim of the study was to assess the seasonal variations of suicides in Lithuania throughout the years 1993-2002, describing patterns by gender, age and method of suicide. METHODS The study material consisted of all registered suicides (n = 16,147) committed throughout 1993-2002 in L...

The production of seasonal and pandemic influenza vaccines depends on the timely availability of suitable reference viruses.Seasonal vaccines are traditionally produced from high-growth reassortant viruses, which have been derived empirically using well-established techniques. However, it is not possible to use such approaches in deriving vaccine reference viruses from highly pathogenic H5N1 vi...

BACKGROUND Child under nutrition is an underlying factor in millions of under-five child deaths and poor cognitive development worldwide. Whilst many studies have examined the levels and factors associated with child under nutrition in different settings, very little has been written on the variation of child under nutrition across seasons. This study explored seasonal food availability and chi...

Non-migratory resident species should be capable of modifying their foraging behavior to accommodate changes in prey abundance and availability associated with a changing environment. Populations that are better adapted to change will have higher foraging success and greater potential for survival in the face of climate change. We studied two species of resident central place foragers from temp...

Mixed-layer dynamics exert a first order control on nutrient and light availability for phytoplankton. In this study, we examine the influence of mixed-layer net community production (NCP) in Southern Ocean intra-seasonal, seasonal, interannual, decadal timescales, using biogeochemical Argo floats satellite-derived NCP estimates during period from 1997 to 2020. On intraseasonal shoaling mixed l...

Two opposing hypotheses concerning determinants of mangabey (Cercocebus albigena) ranging patterns have been advocated. One hypothesis suggests that ranging patterns of mangabeys are largely a response to fruit availability, while the other hypothesis advocates that concerns of fruit availability are supplemented or overridden by concerns of fecal contamination and that the risk of parasite inf...

The mechanisms controlling abundance and biomass of meiofauna in marine sub-littoral systems are still poorly known. The structure of a meiobenthic community is the product of an intricate network of abiotic factors, which interact with biotic factors like food availability, intraand interspecific interactions and predation (Giere 1993). In spite of this inherent complexity, the temporal variat...

Climate change and fast extension in climatically suboptimal areas threaten the sustainability of rubber tree cultivation. A simple framework based on reduction factors of potential transpiration was tested to evaluate the water constraints on seasonal transpiration in tropical sub-humid climates, according pedoclimatic conditions. We selected a representative, mature stand in a drought-prone a...
