Society faces a growing challenge in the management of zoonotic wildlife diseases. Unique attributes of zoonotic diseases and the shifting sociocultural contexts within which diseases are experienced create serious challenges for managers. We address 2 critical questions: how do uncertainty and severity associated with a zoonotic disease relate to public management attitudes and preferences, an...

submucosal dissection (ESD) is a minimally invasive treatment and enables en bloc resection of large le-sions. However, ESD is a technically demanding and time-consuming procedure. 1 Here, we report a " two-sword fencing " technique with an injection needle and an ESD knife. A 74-year-old man presented with a laterally spreading tumor (LST), 7 cm in diameter, on the right wall of the rectum, an...

Globally, rangelands are undergoing rapid social-ecological changes, yet the scale of these changes is rarely measured. Fencing, sedentarization, and land conversion limit access by wildlife livestock to vital resources such as water seasonal forage, leading rangeland degradation. In addition, connectivity between sub-populations, triggering a spiral decreasing biodiversity weakening ecosystem ...

The Czech University of Life Sciences Farm at Lany began farming common eland with the aim of achieving full economic self-sufficiency through animal production for breeding and meat. Alternative goals were to verify production technology for farming common eland in captivity and the utilization of this species as an alternative for meat production in mild climatic zones. The model farm was pri...

Nonnative ungulates can alter the structure and function of forest ecosystems. Feral pigs in particular pose a substantial threat to native plant communities throughout their global range. Hawaiian forests are exceptionally vulnerable to feral pig activity because native vegetation evolved in the absence of large mammalian herbivores. A common approach for conserving and restoring forests in Ha...

The oceans have long been recognized as one of humanity’s most important natural resources. Their vastness has made them appear to be limitless sources of food, transportation, recreation, and awe. The difficulty of fencing and policing them has left them largely as open access resources to be exploited by anyone with the means. However, in recent times we have begun to reach the limits of the ...

Exclosure studies have been used to great advantage in the Hawaiian Islands to evaluate and demonstrate impacts of alien vertebrate herbivores upon native vegetation. Information presented for 50 exclosures, mostly on Hawaii and Maui, shows a wide range of vegetation responses. In most situations, native biota hold their own or increase following removal of vertebrate damage, but the chance of ...

This paper describes investigations that have been undertaken on the effect of heavy vehicle traffic on residents. The study focused on sixteen roads in four North Island communities. The roads selected were predominantly regional arterial roads and had heavy vehicle volumes ranging from 2.1% to 32% of total traffic volume. The study had two main components, a residents' survey and an environme...

In recent years, steppe degradation in North China has become a serious environmental problem. Most research on steppe degradation is conducted at the level of communities or at the scale of small regions. To better understand the spatio-temporal variation and driving factors of grassland degradation, monitoring and analysis at broad regional scales are needed. This paper systematically describ...
