Are human‐altered landscapes reshaping carnivore niche spaces in the Trans‐Himalaya?

open access: yesWildlife Biology, EarlyView.
Understanding carnivore interactions under growing human pressures is crucial for conservation. We examined spatial and temporal niche structuring among snow leopards Panthera uncia, Himalayan wolves Canis lupus chanco, and red foxes Vulpes vulpes; while also incorporating free‐ranging dogs Canis lupus familiaris as a human‐subsidized mesopredator ...

Grain legume nitrogen fixation and balance model for use in practical (organic) agriculture [PDF]

open access: yes, 2005
In extensive agricultural systems, i.g. organic farming, nutrient balance calculations are of high importance. Common calculation models for nitrogen fixation of grain legumes are either of far too much complexity especially for use in agricultural ...

A new approach for rapid measurement of directional root responses to neighbours using the root centroid

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Measuring directional root placement is critical for understanding plant responses to their below‐ground environment, and particularly their competing neighbours. Directional root placement is commonly measured using image analysis of roots growing in transparent pots (rhizoboxes), where the length of the root system of the target plants is ...

Seasonal variation in species composition and frequency of insecticide resistance alleles (kdr and ace-1r) in the Anopheles gambiae complex from an irrigated rice fields area in Western Burkina Faso [PDF]

open access: yes, 2009
Monitoring of the spread of insecticide resistance in field vector populations is a prerequisite for the implementation of efficient and sustainable vector control strategies based on the use of insecticides. Screening for resistance alleles in Anopheles

Living by the lake: Plant food diversity in a prehistoric lake‐dwelling community in the Republic of North Macedonia

open access: yesArchaeometry, EarlyView.
Abstract This paper explores the relationship between wetland ecosystems and prehistoric lakeshore settlements within the Lake Ohrid basin (a biodiversity hotspot) by considering plant food systems at Ploča Mičov Grad, North Macedonia. The mid‐fifth millennium (c.4555–4373 to 4437–4241 cal BCE) waterlogged assemblage contained a diverse spectrum of ...

Behavior and Impact of Zirconium in the Soil–Plant System: Plant Uptake and Phytotoxicity [PDF]

open access: yes, 2013
Because of the large number of sites they pollute, toxic metals that contaminate terrestrial ecosystems are increasingly of environmental and sanitary concern (Uzu et al. 2010, 2011; Shahid et al. 2011a, b, 2012a).

Underutilised crops in Europe: An interdisciplinary approach towards sustainable practices

open access: yesArchaeometry, EarlyView.
Abstract In the context of a rapidly growing global population and significant climatic and environmental change, there is an urgent need to produce nutritious food in a sustainable manner. Some crops are underutilised in Europe, despite their suitability to local environments, viability for sustainable production and potential to improve diets.
