| Background: The inhabitants of deep-sea hydrothermal vents occupy ephemeral island-like habitats distributed sporadically along tectonic spreading-centers, back-arc basins, and volcanically active seamounts. The majority of vent taxa undergo a pelagic larval phase, and thus varying degrees of geographical subdivision, ranging from no impedance of dispersal to complete isolation, often exist among taxa that span common geomorphological boundaries. Two lineages of Bathymodiolus mussels segregate on either side of the Easter Microplate, a boundary that separates the East Pacific Rise from spreading centers connected to the Pacific-Antarctic Ridge. Results: A recent sample from the northwest flank of the Easter Microplate contained an admixture of northern... |

| A növénynemesítés fokozatosan romló működési körülményei, a hatékony marketing és a vetőmagkereskedelem hiányosságai, a külföldi fajták nyomása következtében több növényfajban a hazai nemesítés jelentősége csökkent az utóbbi 20 évben, sőt néhány növényfaj nemesítése Magyarországon meg is szűnt. A Kompolton folyó őszi árpa nemesítés eredményesen állt helyt a külföldi fajtaelőállítók nyomásának. Fajtáink kiváló termőképessége mellett, kiemelkedő télállósággal, igen jó szárszilárdsággal, megbízható állóképességgel, összességé-ben kiváló alkalmazkodóképességgel rendelkeznek. Összesen 12 takarmányárpa és 2 őszi sörárpa fajtánkkal minden termesztési választékkal rendelkezünk. 2004-ben az OMMI kísérletekben a korai és a középérésű csoportban is két-két fajtánk... |

| Hybridization between divergent lineages often results in reduced hybrid viability. Here we report findings from a series of independent molecular analyses over several seasons on four life stages of F1 hybrids between the newts Triturus cristatus and T. marmoratus. These two species form a bimodal hybrid zone of broad overlap in France, with F1 hybrids making up about 4% of the adult population. We demonstrate strong asymmetry in the direction of the cross, with one class (cristatus-mothered) making up about 90% of F1 hybrids. By analyzing embryos and hatchlings, we show that this asymmetry is not due to prezygotic effects, as both classes of hybrid embryos are present at similar frequencies, implicating differential selection on the two hybrid classes... |

| Abstract Marine turtle hybridization is usually sporadic and involves reports of only a few individuals; however, Brazilian populations have high hybridization rates. Here we investigated the presence of hybrids in morphologically identified immature hawksbills (Eretmochelys imbricata) along the South Western Atlantic (SWA). We sequenced one mitochondrial (D-Loop) and three nuclear DNA (RAG1, RAG2, and CMOS) markers to better understand the patterns and characteristics of hybrids. We identified 22 hybrids (n = 270), 11 of them at the extreme South of the SWA. Uruguay had the highest hybrid frequency in the SWA (~37.5%) followed by southern Brazil with 30%. These are common areas for loggerheads (Caretta caretta) but uncommon for hawksbills, and these... |
