Genetic variation and population structure of clonal Zingiber zerumbet at a fine geographic scale: a comparison with two closely related selfing and outcrossing Zingiber species

期刊: BMC ECOLOGY AND EVOLUTION, 2021; 21 (1)

Background There has always been controversy over whether clonal plants have lower genetic diversity than plants that reproduce sexually. These confli......

The complete mitochondrial genome of the intertidal spider (Desis jiaxiangi) provides novel insights into the adaptive evolution of the mitogenome and the evolution of spiders

期刊: BMC ECOLOGY AND EVOLUTION, 2021; 21 (1)

Background: Although almost all extant spider species live in terrestrial environments, a few species live fully submerged in freshwater or seawater. ......

Genome-wide characterization of MATE gene family and expression profiles in response to abiotic stresses in rice (Oryza sativa)

期刊: BMC ECOLOGY AND EVOLUTION, 2021; 21 (1)

Multidrug and toxic compound extrusion (MATE) proteins are involved in many physiological functions of plant growth and development. Although an incre......

Searching for signatures of positive selection in cytochrome b gene associated with subterranean lifestyle in fast-evolving arvicolines (Arvicolinae, Cricetidae, Rodentia)

期刊: BMC ECOLOGY AND EVOLUTION, 2021; 21 (1)

Background: Mitochondrial genes encode proteins involved in oxidative phosphorylation. Variations in lifestyle and ecological niche can be directly re......

Structural comparison of the rostra of two species of weevils coexisting on Ailanthus altissima: the response to ecological demands of egg deposition

期刊: BMC ECOLOGY AND EVOLUTION, 2021; 21 (1)

Background Elongated rostra play an important role in the egg-laying of weevils, and its emergence plays a key role in the adaptive radiation of weevi......

Consequences of mutation accumulation for growth performance are more likely to be resource-dependent at higher temperatures

期刊: BMC ECOLOGY AND EVOLUTION, 2021; 21 (1)

Background Mutation accumulation (MA) has profound ecological and evolutionary consequences. One example is that accumulation of conditionally neutral......

The evolution of opsin genes in five species of mirid bugs: duplication of long-wavelength opsins and loss of blue-sensitive opsins

期刊: BMC ECOLOGY AND EVOLUTION, 2021; 21 (1)

Background Color vision and phototactic behavior based on opsins are important for the fitness of insects because of their roles in foraging and mate ......

DeepHBV: a deep learning model to predict hepatitis B virus (HBV) integration sites

期刊: BMC ECOLOGY AND EVOLUTION, 2021; 21 (1)

Background The hepatitis B virus (HBV) is one of the main causes of viral hepatitis and liver cancer. HBV integration is one of the key steps in the v......

Context-dependent and -independent selection on synonymous mutations revealed by 1,135 genomes of Arabidopsis thaliana

期刊: BMC ECOLOGY AND EVOLUTION, 2021; 21 (1)

Background Synonymous mutations do not alter the amino acids and therefore are regarded as neutral for a long time. However, they do change the tRNA a......

Exploring the evolutionary characteristics between cultivated tea and its wild relatives using complete chloroplast genomes

期刊: BMC ECOLOGY AND EVOLUTION, 2021; 21 (1)

Background Cultivated tea is one of the most important economic and ecological trees distributed worldwide. Cultivated tea suffer from long-term targe......

Assessment of habitat change on bird diversity and bird-habitat network of a Coral Island, South China Sea

期刊: BMC ECOLOGY AND EVOLUTION, 2021; 21 (1)

Background Understanding how island ecosystems change across habitats is a major challenge in ecological conservation under the conditions of habitat ......

Evolutionary ecology of the visual opsin gene sequence and its expression in turbot (Scophthalmus maximus)

期刊: BMC ECOLOGY AND EVOLUTION, 2021; 21 (1)

BackgroundAs flatfish, turbot undergo metamorphosis as part of their life cycle. In the larval stage, turbot live at the ocean surface, but after meta......

Intraspecific variation in the Cambrian: new observations on the morphology of the Chengjiang euarthropod Sinoburius lunaris

期刊: BMC ECOLOGY AND EVOLUTION, 2021; 21 (1)

Background The Chengjiang biota from southwest China (518-million-years old, early Cambrian) has yielded nearly 300 species, of which more than 80 spe......

Integrative taxonomy and molecular phylogeny of three poorly known tintinnine ciliates, with the establishment of a new genus (Protista; Ciliophora; Oligotrichea)

期刊: BMC ECOLOGY AND EVOLUTION, 2021; 21 (1)

Background The taxonomic classification of the suborder Tintinnina Kofoid & Campbell, 1929, a species-rich group of planktonic ciliated protistans......
