The Modified Pharaoh Approach: Stingless bees mummify beetle parasites alive
Social insect colonies usually live in nests, which are often invaded by parasitic species. Workers from these colonies use different defence strategies to combat invaders. Nevertheless, some paras…

Swift sympatric adaptation of a species of cattle tick to a new deer host in New-Caledonia
The occurrence and frequency of sympatric speciation in natural systems continue to be hotly debated issues in evolutionary biology. This might reflect the timescale over which evolution occurs res…

Prey capture and meat-eating by the wild colobus monkey Rhinopithecus bieti in Yunnan, China
If it is true that extant primates evolved from an insectivorous ancestor, then primate entomophagy would be a primitive trait. Many taxa, however, have undergone a dietary shift from entomophagy t…

Study of Fish Weight Loss in Solar Dryer Across Different Agro-Ecological Zones of Nigeria
Drying sessions were conducted across Nigeria to study the interaction between fish weight loss and the meteorological parameters. Correlation analyses using weight loss values show that latitude i…

Population genetic structure of the pelagic goby, Sufflogobius bibarbatus, in the Northern Benguela ecosystem, based on PCR-RFLP analysis of the mitochondrial control region and the ND 3 and 4 region (Dissertation).
Polymorphism within the mitochondrial NADH-3,4 dehydrogenase(ND-3/4) and control region (D-Loop) was studied by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysi…

Population Dynamics
Explicit assumption that the use of natural resources promoting and sustaining growth is proportional to the number of people living on the planet at any given time leads to a model, which reproduc…

The impact of radiation factor on the content of low-molecular antioxidants in Melandrium album and Bromopsis inermis
The East-Ural Radioactive Trace (EURT) is a result of the Mayak Production Association accident occurred in 1957. The area is a unique ground to estimate remote consequences of anthropogenic radiat…

Glacial cycles promote greater dispersal, which can help explain larger clutch sizes, in north temperate birds
Earth’s glacial history and patterns in the life history traits of the planet’s avifauna suggest the following interpretations of how recent geological history has affected these key characteristic…

The Antarctic ‘ozone hole’ combined with no sea ice causes severe oxidative damage in echinoid embryos
Over the past three decades, the ‘ozone hole’ has caused a transient increase in the levels of ultraviolet B radiation (UV-B, 280 to 320 nm) reaching Antarctic coastal marine ecosystems1. The dir…
