Catching Fish and Avoiding Sharks
Although researchers agree that the first 5 years of life are critical for children’s developing executive functions (EFs), further advances are hindered by a lack of consensus on the design and selection of developmentally appropriate EF tasks for young children. Given this debate, well-established adult measures of EF routinely have been adapted for young children. Given young children’s comp...
متن کاملCatching more flies with vinegar
Two signalling pathways work together to reshape olfactory responses so that hungry flies are attracted to food sources they would otherwise ignore.
متن کاملOverfishing causes frequent fish population collapses but rare extinctions.
Burgess et al.’s report in PNAS, “Range contraction enables harvesting to extinction” (1), provides a highly valuable perspective on the consequences of species range contractions that maintain local densities of declining populations. The authors suggest that this densitydependent contraction maintains local harvesting yields and economic incentives that enable depleted natural populations of ...
متن کاملFish market prices drive overfishing of the ‘big ones’
The relationship between fish market price and body size has not been explored much in fisheries science. Here, the mean market prices and fish body size were collected in order to examine the hypothesis that large fish, both among- and within-species, are being selectively targeted by fisheries because they may yield greater profit. Trophic levels, vulnerability to fishing and global landings ...
متن کاملAnglers’ Probabilities of Catching Record-Size Fish
—Most state fishery management agencies publish lists of the largest (e.g., 10, 25, and 50) specimens of each species captured by anglers. We fitted normal distributions for smallmouth bass Micropterus dolomieu and striped bass Morone saxatilis and a mixture of two normal distributions of largemouth bass Micropterus salmoides to the length of time that individual fish had been present on lists ...
