Prioritizing and making efficient conservation plans for threatened populations requires information at both evolutionary and ecological timescales. Nevertheless, few studies integrate multidisciplinary approaches, mainly because of the difficulty for conservationists to assess simultaneously the evolutionary and ecological status of populations. Here, we sought to demonstrate how combining gen...

The United Nations Decade on Ecosystem Restoration (https://www.decadeonrestoration.org/) offers hope in a particularly turbulent time human history. We write this the throes of COVID-19 pandemic that has disrupted entire planet's social systems exacerbated by increasing totalitarianism, kakistocracy, racism, sexism, homophobia, and transphobia. Hope seems short supply. A practical path to buil...

This study reports the effects of a field trip environmental education program with a social-ecological perspective on the experience and learning of university students from China, Japan, South Korea and Vietnam. The students visited Jeju Island, the Saemangeum Sea Dike, the Demilitarized Zone and Seoul, South Korea. Their experiences and learning about social-ecological interactions were anal...

The global decline in estuarine and coastal ecosystems is affecting critical ecosystem services. The spatial agglomeration of population, industries and resources has led to the emergence of regionally-specific ecological problems. Therefore, identifying “ecological red lines”, based on specific natural and environmental features, could help to differentiate the economic development and ecologi...

2 According to the immunologist Eduardo Schiffrin from Switzerland, intestinal microflora can be considered to be an organ in its own right. In fact, intestinal microflora, made of a wide variety of bacteria, is capable, like an organ, of accomplishing important functions that can be modulated by environmental factors such as nutrition. This organ has the special feature of being acquired after...

Introduction Autonomy is crucial in planetary robotics where extreme distance and limited resource availability make continuous teleoperation impractical. Environmental obstacles represent a fundamental hurdle, as natural hazards may prevent robots from accomplishing certain tasks by invalidating path plans. In the worst-case scenario, it may even result in physical harm to the robot. Valuable ...

today, determination of the ecological species groups for current and future situation of forest and its relationship with environmental factors is necessary for forest management. for this purpose, 50 plots were established in altitude range of 2091- 2811 meters above sea level and 600 hectare in protected area of western dena. four ecological groups was identified using twinspan analysis that...

The CLF own and use a variety of high dynamic range CCD cameras that are used for a variety of measurements on many of the experiments performed at the facility. The performance and characteristics of these cameras are of utmost importance when choosing which camera to use in any particular circumstance. Therefore, a calibration to determine the dynamic range and threshold sensitivity of the ca...
