Overwintering capability and spring population size of honeybee colonies (Apis mellifera L.) in Hungary

International Journal of Horticultural Science, 2000
Honeybee races and ecotypes of different genetic background have different population development in spring. Some of them can reach the necessary population size by the beginning of Robinia pseudoacacia (black locust) blooming period.

Integrating fossil data in ecological niche models to improve predictions of future habitat of Caribbean corals

Conservation Biology, EarlyView.
Abstract Ecological niche models (ENMs) are used to assess the abiotic preferences of species by linking their occurrences to the environmental conditions in which they live. We developed a fossil‐informed ENM framework that integrates mid‐Holocene and modern occurrences to test niche stability and reconstruct abiotic niche characteristics for four ...

Genetic and Ecological Management of Pacific Salmon Fisheries for the 21st Century

Fisheries Management and Ecology, EarlyView.
ABSTRACT Based on ecological adaptation theory, tremendous effort is being spent on measures that are eliminating salmon hatcheries and fishing opportunities with the intention of protecting wild runs deemed to be of particular genetic importance to the survival of the species.

Variability Among Ecotypes of Barnyardgrass (Echinochloa Crus-Galli Var. Crus-Galli (L.) Beauv.) and its Susceptibility to Exserohilum Longirostratum [PDF]

, 2005
Barnyardgrass (Echinochloa crus-galli var. crus-galli (L.) Beauv) is one of the most noxious weeds found in rice fields of both Malaysia and Indonesia. Its diversity in morphological and molecular traits within and between the regions of Malaysian and

Genes, fish and fisheries: translating science into policy

Journal of Fish Biology, EarlyView.
Abstract The 2024 Annual Symposium of the Fisheries Society of the British Isles reviewed the burgeoning impact of ‘omics’ technologies on fish ecology, management and forecasting. As with life sciences more generally, major advances in speed, cost‐effectiveness and breadth of applications in ‘omics’ has had profound societal and environmental impacts.

Influence of temperature and species origin on Fusarium spp. and Microdochium nivale pathogenicity to wheat seedlings

Plant Protection Science, 2010
The influence of temperature and species origin on the in vitro growth rate and pathogenicity of Fusarium and Microdochium nivale (F. avenaceum, F. culmorum, F. graminearum, F. poae, and M. nivale) to wheat seedlings was examined.

Northern cod (Gadus morhua) movement: insights from acoustic telemetry and genomics

Journal of Fish Biology, EarlyView.
Abstract Knowledge of the timing and diversity of fish movements within a commercially exploited stock complex is required to ensure the sustainability of fisheries. Although migration can be driven by environmental factors, genomic mechanisms also play an important role in this complex life‐history trait. The northern cod (Gadus morhua) stock complex,

Ontogeny of escape response and body shape in threespine stickleback (Gasterosteus aculeatus L.)

Journal of Fish Biology, EarlyView.
Abstract Escape responses in fishes provide insight into accelerative motions and behavioural response times of these animals, linking numerous fitness‐related traits. We sought to connect escape response performance to genotype and phenotype across ontogenetic stages within a single population of threespine stickleback (Gasterosteus aculeatus L.) to ...
