In a mesocosm experiment, we tested whether larval fish show an active behavioural response to hydrodynamic impacts. Exposing I to 3 week old allis shad (Alosa alosa) larvae to a pulsed wave regime, we found that already I week old larvae immediately adapt their microhabitat use and activity patterns at the onset of the wave pulses. The fish larvae in stantaneously increased their activity leve...

There are many reasons for decrease of the functional activity of the brain like aging of the neurons, bacterial diseases and neuro inflammations. Nowadays, the effects of exercise on physical and mental health have been proven but its effects on motor functions as well as neuro inflammation is an issue that has recently been studding. Neuro inflammation is a mechanism that can be caused by B...

c onservationists and agriculturists face unprecedented challenges trying to minimize tradeoffs between increasing demands for food, fiber, feed, and biofuels and the resulting loss or reduced values of other ecosystem services, such as those derived from wetlands and biodiversity (Millenium Ecosystem Assessment 2005a, 2005c; Maresch et al. 2008). The Food, Conservation, and Energy Act of 2008 ...

Sustainable development requires methods and tools to measure and compare the environmental impacts of human activities for the provision of goods and services (both of which are summarized under the term "products"). Environmental impacts include those from emissions into the environment and through the consumption of resources, as well as other interventions (e.g., land use) associated with p...

The urban heat island effect 1 can be detected throughout the year, but it is of particular public policy concern during the summer, because higher surface air temperature is associated with increases in electricity demand for air conditioning, air pollution, and heat stress–related mortality and illness (Rosenfeld et al. 1995; Nowak et al. 2000; Sailor et al. 2002; Hogrefe et al. 2004). In New...

This commentary describes the likely impacts on children's health and wellbeing from climate change, based on the solid science of environmental child health. It describes likely climate change scenarios, why children are more vulnerable than older people to these changes, and what to expect in terms of diseases (e.g., infections, asthma) and problems (e.g., malnutrition, mental illness). The c...

a r t i c l e i n f o Recreation and wildlife observations occur often in hiking trails. In terms of recreation planning, few studies have combined ecological and cultural features to assess ecotourism potential of hiking trails. Seasonality has been also neglected in tourism research. In order to disperse tourists over the year and alleviate the negative impacts of mass tourism events, we prop...
