Strategies to Identify Adaptive Genes in Hybridizing Trees like Oaks and Poplars

open access: yesNotulae Botanicae Horti Agrobotanici Cluj-Napoca, 2014
Ecologically divergent, hybridizing species such as oaks and poplars provide models to identify genomic regions under selection and adaptive alleles that are transferred between species in hybrid zones.

Evaluation of chromosomal instability in somatic cells of farmed foxes [PDF]

open access: yesArchives Animal Breeding, 2018
The micronucleus (MN) test is a common tool used to evaluate cellular genetic instability at the chromosomal level. It determines the effect of physical, chemical and environmental factors on DNA, and thus the body's individual resistance to harmful ...

Morphological variability of otolith organs in three congeneric Pagellus species

open access: yesOceanological and Hydrobiological Studies
Morphological features of sagittal otoliths in Pagellus acarne, P. bogaraveo, and P. erythrinus samples collected from the Aegean Sea were used to assess the variability both between Pagellus species and between otolith pairs employing scanning electron ...

Intraspecific variability among Lannea species reveals promising morphotypes and ethnotypes in the semi-arid savannas of Burkina Faso (West Africa)

open access: yesJournal of Agriculture and Food Research
Lannea species are among the fruit trees with high socio-economic importance in West Africa yet their intraspecific variability remains poorly studied, despite being essential for selection and domestication.

The genetic architecture of interspecific variation in mimulus. [PDF]

open access: yesGenetics, 1989
Abstract The genetic architecture of various floral and morphological differences between Mimulus cupriphilus and Mimulus guttatus is investigated. M. cupriphilus is believed to have speciated from M. guttatus in the recent past. The two parent species, the F(1) and F(2), and two backcrosses were grown and scored for 23 different ...

Responses of Intraspecific and Interspecific Trait Variations to Nitrogen Addition in a Tibetan Alpine Meadow

open access: yesPlants
A community functional structure may respond to environmental changes such as nitrogen (N) enrichment by altering intraspecific and interspecific trait variations.

Origins of interspecific variation in lizard sprint capacity [PDF]

open access: yesFunctional Ecology, 2001
Abstract1. Data were compiled on maximal sprint speed, body mass and temperature in squamate lizards from the literature and from our own data on lacertid lizards.2. Both traditional (i.e. non‐phylogenetic) and phylogenetic statistical analyses showed that sprint speed is positively correlated with body mass (‘bigger is better’) and temperature ...

Influence of temperature and pH on S. bayanus var. uvarum growth; impact of a wine yeast interspecific hybridization on these parameters [PDF]

open access: yes, 2005
The species Saccharomyces bayanus var. uvarum possesses interesting enological characteristics but produces high concentration of volatile fermentative compounds not desirable in Sauvignon blanc wines.

Genome size variation among and within Camellia species by using flow cytometric analysis. [PDF]

open access: yesPLoS ONE, 2013
BACKGROUND: The genus Camellia, belonging to the family Theaceae, is economically important group in flowering plants. Frequent interspecific hybridization together with polyploidization has made them become taxonomically "difficult taxa".
