Wind turbines have minor impact on small-bird populations

Only about two or three small birds are killed by wind turbines each year for every 225-300 houses supplied with renewable energy, new research suggests. The study collated data from 116 US and Canadian studies on 156 species of passerines (small birds). The study suggests some species are affected more than others, but that wind turbines generally have only a minor impact on these small-bird populations.

Bear hunting's hidden impacts on cubs is highlighted in new study

Hunting has obvious impacts on wild populations. However, new research concludes that for Scandinavian brown bears (Ursus arctos), it also contributes to the killing of cubs by adult males to increase the male's chances of mating with the cubs' mother. The researchers say that this indirect effect of hunting should be considered when developing sustainable hunting quotas and management plans.

Artificial light at night — the impact on plants and ecology

Artificial light — such as street lighting and passing car headlights — has an impact on plants. A new study suggests there could also be broader implications for the interactions of herbivores and pollinators. The study highlights that disrupting seasonal light cues with artificial light has far-reaching effects, including: mismatches in timing with herbivores; altering the development of agricultural crops; inhibiting flowering in wild species; decreasing periods of darkness necessary for plant repair from environmental pollutants; and causing barriers to nocturnal pollinator species.

The hidden biodiversity impacts of global crop production and trade

The rise in intensive agriculture, and associated land-use change, is a major driver of biodiversity loss. This study evaluated these effects via international food trade, calculating estimates of species loss for 170 crops and 184 countries. The results show that the majority of biodiversity loss is due to growing crops for domestic consumption but that industrialised countries can ‘import’ negative impacts from tropical regions.

Agri-environment schemes: impacts on the agricultural environment June 2017

What has been the impact of Agricultural Environment Schemes (AES) on European farming? These schemes provide payments to farmers in return for the implementation of agri-environmental measures to encourage positive environmental outcomes and as a counterbalance to the profit incentive. The schemes might concentrate on low-intensity production, organic or integrated management or enhancement of biodiversity on farmland. This Thematic Issue presents recent peer-reviewed research examining the impacts AES have had on European farm ecosystems, biodiversity and farmers – and to what extent AES have benefited a range of animals and plants by increasing the number of individuals and species.
