The effects of urbanisation on ecological interactions

Urbanisation has been shown to impact multiple ecological traits of insects, such as changes in emergence times and phenology (e.g. butterflies [10] ), thermal tolerances (e.g. ants [11] ), body-size shifts (e.g. bees [12] ), and niche shifts (e.g. mosquitos [13] ). Paradoxically, though, studies have also shown that cities can contain a large ...

Manure- and straw-derived biochars reduce the ecological …

Straw-derived biochar showed a higher ability to adsorb PBDE and to reduce PBDE ecological risk. • Manure-derived biochar facilitated microbial degradation of BDE-47. • BDE-47 was stepwise debrominated into lower brominated PBDE by PBDE-degrading bacteria. • Both types of biochar favored Nitrospirae bacteria and promoted N cycling.

Can China's transfer payment in key ecological function areas reduce …

Results show the following: (1) the transfer payment policy in key ecological function areas has significantly reduced the carbon intensity, and the research conclusion is still valid after the robustness test; (2) the transfer payment policy in key ecological function areas reduces the carbon intensity by promoting the upgrading of industrial ...

Amino acids metabolism by rumen microorganisms: Nutrition and ecology

Restricting autumn grazing pastures on New Zealand farms can reduce the direct and indirect N 2 O emissions (De Klein et al., 2006). Moreover, New Zealand dairy farms are increasingly encouraging the strategic use of isolation mats during the rainy season to reduce the risk of N loss in the soil (De Klein et al., 2006). 4.2.

Assessing the impact of environmental regulations on ecological …

Environmental regulation reduces ecological risk in a variety of ways. First, it can reduce the ecological risk from the source of pollution. Government regulation policies can raise the entry threshold of market enterprises, timely and effectively stop and correct the behavior of local polluters, and reduce the pressure on the ecology (Zhang ...

Direct and ecological costs of resistance to herbivory

Direct resistance cost: a tradeoff between fitness and resistance that is not mediated by interactions with other species (e.g. allocation costs, auto-toxicity, opportunity costs, changes in phenology, growth rate, dormancy and other auto-ecological traits, and increased susceptibility to abiotic stresses).

Direct and indirect ecological effects of biological control

Historically, biological control has been a widely acceptable, 'green' approach to pest management. The need for biological control is not diminishing; not only are 'pests' still causing agricultural and forestry losses, but invasive species are also second only to habitat destruction as a threat to biodiversity. Recently, however, negative indirect …

Ecology of fear

The ecology of fear posits that the behavioural, physiological and neurobiological costs of avoiding predation ('fear' for short) may additionally reduce prey fecundity and survival, and the total reduction in prey numbers resulting from exposure to predators may thus far exceed that due to direct killing alone. If this is the case, then ...
