A new study investigates how the success of a wild pig invasion may be dependent on how they use their surrounding food resources, and how when it comes to agriculture, the pigs continue their destructive trend.
Read moreCapturing elephants to keep in captivity not only hinders their reproduction immediately, but also has a negative effect on their calves, according to new research.
Read moreAmong birds, the practice of laying eggs in other birds' nests is surprisingly common. This phenomenon, known as brood parasitism, was unknown in coral reef fish because most marine fish don't provide any parental care at all. Now, however, biologists studying an unusual kind of coral reef fish that does care for its young have found that, sure enough, other fish are taking advantage of this to get free parental care for their offspring.
Read moreThe glacial relict amphipod Gammaracanthus lacustris only occurs in deep and cold waters. A new study produced new information on the life cycle and ecology of this rare amphipod. G. lacustris is adapted to cold water and would probably not survive in rising water temperatures due to climate change.
Read moreIn an industry struggling to maintain profitability, it's curious that U.S. processing sweet corn – the corn that ends up in cans and freezer bags – is falling so far below its potential. Yet, that's what a new study clearly demonstrates.
Read moreAnother casualty of climate change will likely be shoreline recreational fishing, according to new research. The study finds some regions of the U.S. may benefit from increasing temperatures, but those benefits will be more than offset by declines in fishing elsewhere.
Read moreA research team has now measured concentrations of the hormone corticosterone and its metabolic products in white-tailed sea eagles in northern Germany and correlated these values with potential causes of stress. They found that the levels of corticosterone in the birds' urine are higher the closer a breeding pair's nest is to paths or roads.
Read moreFish use colorful patterns to signal to each other, including advertising for mates and warding off rivals. Studying the relationship between color and behavior sometimes entails anesthetizing and photographing the fish, but anesthetics may alter coloration, influencing the traits researchers are trying to study.
