With the ongoing poaching crisis, escalating population decline and destruction of suitable habitat, extinction of the Sumatran rhino in the near future is becoming increasingly likely.
A well-managed tourist sector can contribute significantly to reducing threats to, and maintain or increase, key wildlife populations and biodiversity values through tourism revenue.
The population of Japanese monkeys in Fukushima City had been systematically managed since 2008 according to a management plan based on law and regulated by Fukushima Prefecture to reduce damage to agricultural crops.
What is Sakura cat? In the 2004 survey, the number of individuals decreased by about 36% in two years, and the number of cats not receiving increased by 47.
Thus, further research is urgently needed to investigate their distribution, population trends, threats and determine if they require any conservation actions.
In this drawing, men are collecting the river water and amplifying certain DNA sequences using a handheld real-time PCR machine to estimate the population of a certain species of fish.
Ben Woodcock and colleagues examine how large-scale applications of neonicotinoids to oilseed rape crops influenced population changes among 62 wild bee species in the UK between 1994 and 2011.
通常生息地を評価するにはその場の生物の種の数とそれぞれの種に属する個体数を目で見て数えます。
The usual methods of evaluating a habitat have been done by visually counting the numbers of species and the numbers of individuals within each species in a given area.
Using new methods to calculate population numbers, Matthew Luskin and colleagues estimated the number of tigers across Sumatra in the past two decades.
They describe a surprisingly modest immune response to infection in Rana, a result that may help explain variable Bd susceptibility across populations and species.
In arid regions, such as parts of Australia, breeding may be irregular and may happen in wet periods, triggered by temporary increases in the populations of small mammals.
They found that the population of Beijing lineage M. tuberculosis increased in multiple spikes over the last 200 years, coinciding with the Industrial Revolution and the First World War; followed by a drop coinciding with the rise of antibiotic use in the 1960s.
