Rumen methanogenic archaea and their correlation with enteric methane emission in ruminant animals: A systematic review and meta‐analysis

open access: yesJSFA reports, EarlyView.
Abstract Background Livestock, especially ruminants, are a major source of global methane emissions, primarily produced by methanogenic archaea during enteric fermentation. We performed a systematic review and meta‐analysis to account for factors that could influence the relationship between ruminal methanogenic populations and methane emissions, such ...

Origin and genetic diversity of diploid parthenogenetic Artemia in Eurasia [PDF]

open access: yes, 2013
There is wide interest in understanding how genetic diversity is generated and maintained in parthenogenetic lineages, as it will help clarify the debate of the evolution and maintenance of sexual reproduction.

Microbial communities and functional diversity in seafood

open access: yesJSFA reports, EarlyView.
Abstract Functional diversity encompasses ecosystem processes that enhance adaptability to environmental change. This study explores the diversity of microorganisms associated with seafood. In this paper, we present our knowledge of microbial diversity in relation to seafood.

Gene expression and metabolic variability in fungus‐resistant PIWI (‘Pilzwiderstandsfähig’) grape cultivars

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Fungus‐resistant PIWI (Pilzwiderstandsfähig) grape cultivars are promising for reducing pesticide inputs in viticulture, but their enological potential is still poorly characterized. We performed a pilot, single‐vintage study integrating berry gene expression and phenolic composition in five Italian red PIWI cultivars (Cabernet ...

Hybridization between wild and cultivated potato species in the Peruvian Andes and biosafety implications for deployment of GM potatoes [PDF]

open access: yes, 2008
The nature and extent of past and current hybridization between cultivated potato and wild relatives in nature is of interest to crop evolutionists, taxonomists, breeders and recently to molecular biologists because of the possibilities of inverse gene ...

Sexual reproduction in invasive Japanese knotweed (Reynoutria japonica) in south Sweden

open access: yesNordic Journal of Botany, EarlyView.
To understand the potential for northward expansion of knotweeds into currently uninvaded regions, it is crucial to assess the potential for sexual reproduction alongside the ongoing vegetative spread. For that reason, we tested viability in Reynoutria japonica seeds in south Sweden, a region where viable seeds had not been previously reported ...

Hybridization constrains the evolution of mimicry complexes in woodpeckers

open access: yesJournal of Avian Biology
The evolution of interspecific mimicry does not always result in perfect resemblance between mimics and models. Differences between members of a mimicry complex can be explained by genetic or developmental constraints.

Effects of outbreeding depression on meristics and bilateral asymmetry in hybrids of spatially separated populations of pink salmon (Oncorhynchus gorbuscha) [PDF]

open access: yes, 2005
Thesis (M.S.) University of Alaska Fairbanks, 2005Different populations of a species distributed over diverse conditions adapt to their local environments to improve their ability to survive or reproduce. Intraspecific hybridization can alter the locally

Isoetes ×atruensis (Isoetaceae – Lycopodiopsida), a new interspecific sterile hybrid from Rajasthan of Western India

open access: yesNordic Journal of Botany, EarlyView.
Isoetes ×atruensis hyb. nov. is shown to be a triploid (2n = 3× = 33 + 1) sterile interspecific hybrid between diploid (2n = 2× = 22 + 1) I. coromandelina and tetraploid (2n = 4× = 44 + 1) I. rajasthanensis. It has been found in two locations in Rajasthan, India.
