Which ecological indicators can robustly detect effects of fishing?

Towards Culturally-Situated Agent Which Can Detect Cultural Differences

Amethod to calculate the semantic dissimilarity in two countries’ pictogram interpretations is proposed. Two countries’ pictogram interpretation words are mapped to SUMO classes via WordNet2SUMO. Appropriate concept weights are assigned to SUMO classes using the interpretation ratios. The edges between the two SUMO classes are counted to obtain the path length of the two classes. Three bipartit...

Application of Ecological Indicators*

Ecological indicators have widespread appeal to scientists, environmental managers, and the general public. Indicators have long been used to detect changes in nature, but the scientific maturation in indicator development primarily has occurred in the past 40 years. Currently, indicators are mainly used to assess the condition of the environment, as early-warning signals of ecological problems...

Ecosystem effects of fishing.

Fishing down and fishing hard: ecological change in the Nile perch of Lake Nabugabo, Uganda

Fishing is a potent ecological force. In Lake Victoria, East Africa, Nile perch, Lates niloticus contributes to a multi-million dollar fishing industry but is threatened by over-exploitation. We quantified spatial and temporal trends in the distribution, diet and size of Nile perch in Lake Nabugabo, Uganda, a satellite of Lake Victoria. From 1995 to 2007, we detected a decline in catch per unit...

Which Threshold to Detect Hypoglycemia?

The Diabetes Control and Complications Trial (DCCT) showed that the improvement of glycemic control by intensive insulin therapy resulted in a decrease in the risk of late diabetic complications. However, this effect was associated with an increase (by a factor of 3) in the risk of severe hypoglycemia (1). This explains the interest in the development of a hypoglycemic alarm that uses continuou...
