Home range shifts and habitat selection across life‐history stages in grey partridges

open access: yesWildlife Biology, EarlyView.
Understanding how birds use space throughout the year is essential for effective conservation planning, even in resident species. We investigated seasonal space use in a Central European population of grey partridges Perdix perdix, a rapidly declining residential farmland bird.

A study on Meligethes (Nitidulidae) species in Keszthely, 2002 [PDF]

open access: yes, 2003
In 2002 we examined when the Meligethes adults emerged from the wintering places and settled in the rape field. We wanted to know how many species within the genus Meligethes, when and in what proportion and rate appeared in oilseed rape as a feed plant.

Nutrient and growth elucidation of a novel coated urea on oilseed rape in three main cultivation areas

open access: yesAdvanced Agrochem
A novel coated urea (MVCU) was prepared, and its application effect was verified by field trials of oilseed rape in three main cultivation areas. Meanwhile, the nutrient release and coating layer changes of MVCU in static water at 25 °C and different ...

Foraging energetics reveals late‐summer challenges for pollinators across two British cities

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Foraging bees often work within fine energetic margins, but recent work has shown that foraging conditions can vary markedly across the year. Despite the importance of seasonality for pollinator foraging, most work in this area has relied on indirect approaches. However,

Efficacy of imazamox in imidazolinone-resistant spring oilseed rape in Finland

open access: yesAgricultural and Food Science, 2008
Imidazolinonies (IMIs) are a group of herbicides inhibiting acetolactate synthase (ALS) activity. They control the growth of many broadleaved weeds and annual grass species.

Functional Expression of Cf9 and Avr9 Genes in Brassica napus Induces Enhanced Resistance to Leptosphaeria maculans

open access: yesMolecular Plant-Microbe Interactions, 2001
The tomato Cf9 resistance gene induces an Avr9-dependent hypersensitive response (HR) in tomato and transgenic Solanaceae spp. We studied whether the Cf9 gene product responded functionally to the corresponding Avr9 gene product when introduced in a ...

Brood parasitism reduces but does not prevent Bombus terrestris reproductive success

open access: yesInsect Science, EarlyView.
Graphical depiction of the colony splitting process. Throughout figures in this paper, results pertaining to host success are represented in blue, and cuckoo success is represented in red. Abstract Cuckoo bumblebees are obligate brood parasites that must invade a colony of their host bumblebee species in order to reproduce.

Approaches to assess the importance of carnivorous beetles as predators of oilseed rape pests

open access: yes, 2004
The feeding ecology and efficacy of common carnivorous beetles from the families Carabidae and Staphylinidae as predators of the most important oilseed rape pest species are currently investigated within the EU-project "MASTER" (MAnagement STrategies for

BnSGS3 Has Differential Effects on the Accumulation of CMV, ORMV and TuMV in Oilseed Rape

open access: yesViruses, 2015
Virus diseases greatly affect oilseed rape (Brassica napus) production. Investigating antiviral genes may lead to the development of disease-resistant varieties of oilseed rape. In this study, we examined the effects of the suppressor of gene silencing 3
