Highly replicated evolution of parapatric ecotypes [PDF]

open access: yesMolecular Biology and Evolution, 2020
AbstractParallel evolution of ecotypes occurs when selection independently drives the evolution of similar traits across similar environments. The multiple origin of ecotypes is often inferred on the basis of a phylogeny which clusters populations according to geographic location and not by the environment they occupy.

Cadmium exclusion a key factor in differential Cd-resistance in Thlaspi arvense ecotypes

open access: yesBiologia Plantarum, 2012
Differences in Cd accumulation and Cd tolerance between Thlaspi arvense ecotype Aigues Vives (AV) from a commercial grower in South France and ecotype Jena collected in the polluted urban area of Jena (Germany) were reported here.

MORPHOLOGICAL AND PRODUCTIVE CHARACTERISTICS OF TWO TSIGAIE ECOTYPES, USED AS GENETIC STOCK

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
This paper investigates the morphological and productive characteristics of two Tsigaie ecotypes belonging to the red variety. They represent genetic stock and semen, oocytes and embryos will be harvested from them in order to be cryopreserved. The sheep

Assessing Populations Diversity of Small Panel Oak (Quercus brantii) in Western Forests of Iran: a Major Effort in Reforestation Programs [PDF]

open access: yesJournal of Nuts
Persian oak (Quercus brantii) is a critical, economic, and environmental species of Zagros forests in Iran. The effects of climate change and drought have caused a decline in Persian oak populations, leading to a severe reduction in genetic resources for

Complex interactions between temperature and relative humidity on water balance of adult tsetse (Glossinidae, Diptera): implications for climate change

open access: yesFrontiers in Physiology, 2011
Insect water balance plays an important role in determining energy budgets, activity patterns, survival and population dynamics and, hence, geographic distribution. Tsetse (Glossina spp.) are important vectors of human and animal disease occupying a wide

Cadmium Induced Changes of Proline in Two Ecotypes of Thlaspi Caerulescens

open access: yesE3S Web of Conferences, 2013
A Thlaspi caerulescens (J. & C. PRESL) was used to study the effect of cadmium on the content of free amino acids and ability accumulation of Cd in ecotypes of this plant species. In pot experiment two ecotypes T.

Contrasting activity patterns determined by BrdU incorporation in bacterial ribotypes from the Arctic Ocean in winter

open access: yesFrontiers in Microbiology, 2013
The winter Arctic Ocean is one of the most unexplored marine environments from a microbiological perspective. Heterotrophic bacteria maintain their activity at a baseline level during the extremely low energy conditions of the winter, but little is known
