Ibis, EarlyView.Free‐living birds need to acquire enough food to fulfil their energetic needs, which may require more effort in habitats with less favourable conditions. Therefore, to maintain their necessary energy intake, birds need to adjust their foraging behaviour in response to varying habitat conditions.

Potentials for fisheries in the Niger Delta: Another green light for self sufficiency in regional food production [PDF]
, 1985 A discussion is presented on the potential for fishery development in the Niger Delta region, considering engineering activities and food production potentials of the freshwater zone and immediate hinterland, the brackishwater mangrove swamps and the ...

Ibis, EarlyView.Understanding the distribution of species is central to conservation biology. Species distribution modelling (SDM) is a standard method used for this purpose, especially for elusive species for which limited occurrence data exist. The Eurasian Woodcock Scolopax rusticola (hereafter Woodcock) is an elusive, woodland‐dwelling wader that is declining in ...

NHS competition: bad science or bad blogging? [PDF]
, 2012 Following yesterday’s post criticising the LSE research that is underpinning the drive towards competition and choice in the NHS, Henry Overman provides a defence of the research findings and questions the extent to which public understanding of the ...

Threatened cockatoo adapts foraging strategy to survive habitat loss from fire
Ibis, EarlyView.Fire regimes are changing across the globe as a result of human‐induced climate change. For granivorous bird species, changes in fire regimes can affect seed availability and the persistence of populations. We investigated the foraging behaviour of Glossy Black Cockatoos Calyptorhynchus lathami halmaturinus, a resource specialist, following large‐scale

INCREASED RESERVOIR BENEFITS: THE CONTRIBUTION OF SOIL CONSERVATION PROGRAMS [PDF]
The objective of this research is to value soil conservation's impact on reservoirs. Using a model based on replacement cost, we estimate the benefits gained by marginal decreases in soil erosion for more than 75,000 reservoirs across the contiguous ...

Forest type influence on Heliconia‐dipteran interaction networks
Insect Conservation and Diversity, EarlyView.Responses to forest type depended on the developmental stage of dipterans. Bract traits and forest type influenced larval abundance, but forest type had no impact on adult alpha and beta diversity. Heliconia‐dipteran interaction networks showed a nested pattern for both forest types.

Year‐round pollinator visitation of ornamental plants in Mediterranean urban parks
Insect Conservation and Diversity, EarlyView.Pollinators visiting ornamental plants in urban parks remained diverse throughout the year. They were represented by wild bees (42%), honeybees (37%), flies (18%), butterflies (2%) and beetles (1%). Both native and non‐native plants attracted pollinators.

VALUING MARGINAL CHANGES IN THE QUALITY OF AN ENVIRONMENTAL ASSET [PDF]
We present a model that extends the replacement cost theory to cases where benefits are restored for multiple years. Our theoretical framework derives a functional relationship between investments expenditures and environmental benefits. By extending the

Water availability and land‐use shape the diversity of Odonata in the Middle East
Insect Conservation and Diversity, EarlyView.Odonata diversity in the Middle East depends on the availability of long‐lasting waters, emphasizing the importance of preserving stable aquatic habitats for biodiversity conservation under climate change‐driven droughts. Agricultural expansion is associated with increased Odonata species richness, but overall trait diversity remains limited ...
