Characterization and phylogenetic analysis of the complete chloroplast genome sequence of xerophyta retinervis (velloziaceae)

open access: yesMitochondrial DNA. Part B. Resources, 2022
Xerophyta retinervis has great ornamental value and numerous traditional uses. This study reported its first complete chloroplast genome sequence, which was 155,109 bp in length, including a pair of inverted repeat regions (IRs) (27,093 bp), a small ...

From Water to Land: The Structural Construction and Molecular Switches in Lungs during Metamorphosis of Microhyla fissipes

open access: yesBiology, 2022
Most anurans must undergo metamorphosis to adapt to terrestrial life. This process enhances the air-breathing ability of the lungs to cope with the change in oxygen medium from water to air. Revealing the structural construction and molecular switches of

Age Determination and Growth Characteristics of the Potentilla griffithii: A Comparison of Two Different Habitats in Western Sichuan Plateau, China

open access: yesPlants, 2023
This study proposes a rapid and non-destructive technique for determining the age of Potentilla griffithii individuals in the field by observing the sequence of leaf scars. Based on two- to three-year-old P.

Females and males respond differently to calls impaired by noise in a tree frog

open access: yesEcology and Evolution, 2021
Both human and nonhuman animals communicating acoustically face the problem of noise interference, especially anurans during mating activities. Previous studies concentrated on the effect of continuous noise on signal recognition, but it is still unknown

Restoration enhances wetland biodiversity and ecosystem service supply, but results are context-dependent: a meta-analysis [PDF]

open access: yes, 2014
Wetlands are valuable ecosystems because they harbor a huge biodiversity and provide key services to societies. When natural or human factors degrade wetlands, ecological restoration is often carried out to recover biodiversity and ecosystem services (ES)

Amphibian community structure along elevation gradients in eastern Nepal Himalaya

open access: yesBMC Ecology, 2019
Background Species richness and composition pattern of amphibians along elevation gradients in eastern Nepal Himalaya are rarely investigated. This is a first ever study in the Himalayan elevation gradient, the world’s highest mountain range and are ...

Comparative Chloroplast Genomics of Sophora Species: Evolution and Phylogenetic Relationships in the Early-Diverging Legume Subfamily Papilionoideae (Fabaceae)

open access: yesFrontiers in Plant Science, 2021
The taxonomy and evolutionary history of Sophora L., a genus with high economic and medicinal value, remain uncertain due to the absence of genetic resource (especially in China) and low polymorphism of molecular markers.

Ecological restoration success is higher for natural regeneration than for active restoration in tropical forests [PDF]

open access: yes, 2017
Is active restoration the best approach to achieve ecological restoration success (the return to a reference condition, that is, old-growth forest) when compared to natural regeneration in tropical forests?
