A comparative study of the function of heterospecific vocal mimicry in European passerines [PDF]

open access: yes, 2007
Although heterospecific vocal imitation is well documented in passerines, the evolutionary correlates of this phenomenon are poorly known. Here, we studied interspecific variation in vocal mimicry in a comparative study of 241 European songbirds.

Cytomolecular identification of individual wheat-wheat chromosome arm associations in wheat-rye hybrids [PDF]

open access: yes, 2013
Chromosome pairing in the meiotic metaphase I of wheatrye hybrids has been characterized by sequential genomic and fluorescent in situ hybridization allowing not only the discrimination of wheat and rye chromosomes, but also the identification of the

Interspecific Hybridization among Mycobacteria [PDF]

open access: yesNature, 1960
EXPERIMENTS conducted in the first part of this work showed that a high degree of streptomycin resistance can be transmitted to M. phlei when a streptomycin-sensitive strain of this micro-organism and a streptomycin-resistant BCG strain of M. tuberculosis are cultured together in ‘Tween’ liquid medium.

Asymmetric somatic plant hybridization : status and applications [PDF]

open access: yes, 2013
To create asymmetric somatic hybrids, the genome of the so-called donor protoplast is fragmented prior to protoplast fusion. As a result, only a limited amount of the donor genome is transferred to the fusion product.

Host adaptation and speciation through hybridization and polyploidy in Phytophthora. [PDF]

open access: yesPLoS ONE, 2013
It is becoming increasingly evident that interspecific hybridization is a common event in phytophthora evolution. Yet, the fundamental processes underlying interspecific hybridization and the consequences for its ecological fitness and distribution are ...

Epigenetic consequences of interploidal hybridisation in synthetic and natural interspecific potato hybrids [PDF]

open access: yes, 2019
Interploidal hybridisation can generate changes in plant chromosome numbers, which might exert effects additional to the expected due to genome merger per se (i.e., genetic, epigenetic and phenotypic novelties).Wild potatoes are suitable to address this ...

Experimental hybridization and reproductive isolation between two sympatric species of tephritid fruit flies in the Anastrepha fraterculus species group [PDF]

open access: yes, 2017
Among tephritid fruit flies, hybridzation has been found to produce local adaptationand speciation, and in the case of pest species, induce behavioral and ecological alterations that can adversely impact efficient pest management. The fraterculus species

Interspecific Hybridization Between Cyclic Parthenogens [PDF]

open access: yesEvolution, 1985
Taxonomic work has suggested that interspecific hybrids are common in freshwater rotifers and cladocerans. Hybrids within the cladoceran genera Bosmina and Daphnia are apparently common in the large lakes of western Europe (Lieder 1956, 1983a, 1983b; Einsle, 1966, 1978).

Biodiversity of interspecific hybrids of the genus Allium L.

open access: yesОвощи России, 2022
Relevance. Interspecific hybridization in the genus Allium L. is the best way to increase biodiversity by introgression of desired traits within the genus.
