When drought eliminates fish…

March 30, 2019

  Droughts can lead to lasting changes in the condition of wetlands.  For example, as drying occurs water levels drop and light penetration improves, which allows aquatic plants in the seed bank to germinate.  By stabilizing sediments, outcompeting algal plankton and  providing refuge to zooplankton grazers, newly established stands of aquatic plants can cause originally […]

Rivers have rights too

  The development of environmental law in the 1960s and 1970s was an important landmark in the movement to conserve species and protect the world’s ecosystems.  However, a weakness of environmental law is that, so far, it’s tended to focus more on the effects of environmental degradation on human interests than on the interests of […]

Surface walkers need impure water

March 30, 2019

  By affecting the way that the surface layer of water is renewed, patterns of subsurface flow have a big influence on many environmental processes, such as evaporation, cooling, aeration and the absorption of atmospheric CO2.  In natural waters, the presence of small amounts of surfactants creates a surface film, about 50 µm thick, that […]

How fire affects stream communities

March 30, 2019

  By removing riparian vegetation, wildfires can have significant effects on river ecology, especially in headwater systems where fringing plant life helps to regulate stream temperature and provides a source of carbon in the form of leaf litter and woody debris.  To help understand the impacts of fire on streams, and the length of time […]

Rapid advancement depends on schooling

  Research suggests that, as well as reducing the risks of predator attack, schooling behaviour can help fish to improve their swimming efficiency.  However, because most studies of swimming performance have been carried out on individual fish, the swimming abilities of schooling species may have been underestimated.  Typically, swimming performance experiments are carried out in […]

Keeping track of groundwater

March 30, 2019

  Groundwater provides almost half of the world’s supply of water for drinking and irrigation.  Intensive groundwater use has led to the depletion and pollution of aquifers, to the extent that about a fifth of all aquifers are now over-exploited.  In an attempt to manage water resources effectively, new systems of water accounting have been […]
