We examined long-term time series of stock status for the temperate tunas Pacific bluefin and albacore in the north Pacific, and characterized temporal changes in the stock status of both species through comparison with tropical tunas in the Western and Central Pacific. The temperate tunas appear to have historically experienced considerable fluctuation in stock status over a long period of tim...

Because of the prolonged history of disturbance caused by intense human activities, restoration in China has been a major task facing many ecologists and land managers. There are six major forest types in China: cold temperate coniferous forest, temperate coniferous and broad-leaved mixed forest, warm temperate deciduous broad-leaved forest, subtropical evergreen broad-leaved forest, tropical r...

The manuscript presents so far unpublished high-quality aircraft measurements of CO2, CO and CH4 from three large wildfires and one prescribed fire in mixed conifer forests of the northwestern United States. From these measurements, the author calculates emission factors (EF) for these species and analyses the relationship between observed modified combustion efficiency (MCE) and EFCH4. The aut...

Philodryas chamissonis, the Chilean long-tailed snake, is a diurnal predator mainly of Liolaemus lizards, but also of amphibians, birds, rodents and juvenile rabbits. Dromiciops gliroides (Colocolo opossum) is an arboreal marsupial endemic of temperate rainforest of southern South America. Little information is available about this marsupial's biology and ecology. Here we report the predation o...

Landscape fragmentation is often a major cause of species extinction as it can affect a wide variety of ecological processes. The impact of fragmentation varies among species depending on many factors, including their life-history traits and dispersal abilities. Felids are one of the groups most threatened by fragmented landscapes because of their large home ranges, territorial behavior, and lo...

The purpose of this study is to analyse the relationship between geo-climate zones of the globe and innovative outputs in order to detect favourable mechanisms that can foster high technological change. Empirical analysis shows that geographical areas with tepid latitudes have higher levels of innovative outputs than non-temperate latitudes. In effect, warm temperate climate has an appropriate ...

The study was conducted to demonstrate expression profile of cold shock protein genes; cold inducible RNA binding protein (CIRP) and RNA binding motif protein 3 (RBM3) in goats (Capra hircus) during different seasons to check the gene expression in different thermal conditions. Blood samples were collected from healthy goats of tropical and temperate region during peak winter, moderate season a...

The Australian landscape, as in many countries, has undergone a significant change. The extent of native forests in Australia has steadily decreased over time since European settlement. The establishment of towns and cities, mining and a range of other factors have all reduced forest cover, however it is land clearing for agriculture that has been the most significant process by far. Along with...

It has been argued that bacterial cells may use their temperate viruses as biological weapons. For instance, a few bacterial cells among a population of lysogenic cells could release the virus and kill susceptible non-lysogenic competitors, while their clone mates would be immune. Because viruses replicate inside their victims upon infection, this process would amplify their number in the arena...
