The skeletome of the red coral Corallium rubrum indicates an independent evolution of biomineralization process in octocorals
Tập 21 Số 1
Abstract Background The process of calcium carbonate biomineralization has
arisen multiple times during metazoan evolution. In the phylum Cnidaria,
biomineralization has mostly been studied in the subclass Hexacorallia (i.e.
stony corals) in comparison to the subclass Octocorallia (i.e. red corals); the
two diverged approximately 600 million years ago. The precious Mediterranean red
coral, Coralli...
Airborne environmental DNA metabarcoding detects more diversity, with less sampling effort, than a traditional plant community survey
Tập 21 Số 1
AbstractBackgroundAirborne environmental DNA (eDNA) research is an emerging
field that focuses on the detection of species from their genetic remnants in
the air. The majority of studies into airborne eDNA of plants has until now
either focused on single species detection, specifically only pollen, or human
health impacts, with no previous studies surveying an entire plant community
through metaba...
Widely used, short 16S rRNA mitochondrial gene fragments yield poor and erratic results in phylogenetic estimation and species delimitation of amphibians
Tập 22 Số 1 - 2022
AbstractBackgroundThe 16S mitochondrial rRNA gene is the most widely sequenced
molecular marker in amphibian systematic studies, making it comparable to the
universalCO1barcode that is more commonly used in other animal groups. However,
studies employ different primer combinations that target different
lengths/regions of the 16S gene ranging from complete gene sequences (~ 1500 bp)
to short fragme...
An exploratory investigation of glucocorticoids, personality and survival rates in wild and rehabilitated hedgehogs (Erinaceus europaeus) in Denmark
Abstract Background The European population of hedgehogs (Erinaceus europaeus)
is declining. It is therefore essential to optimise conservation initiatives
such as the rehabilitation of sick, injured and orphaned hedgehogs. Wild animals
placed in captivity may be prone to chronic stress, potentially causing negative
health effects. Therefore, the effects of these rehabilitation efforts should
cons...
Lizards and snakes from the earliest Miocene of Saint-Gérand-le-Puy, France: an anatomical and histological approach of some of the oldest Neogene squamates from Europe
Tập 21 Số 1
Abstract Background The earliest Miocene (Aquitanian) represents a crucial time
interval in the evolution of European squamates (i.e., lizards and snakes),
witnessing a high diversity of taxa, including an array of extinct forms but
also representatives of extant genera. We here conduct a taxonomical survey
along with a histological/microanatomical approach on new squamate remains from
the earlies...
Limitations of eDNA analysis for Carcinus maenas abundance estimations
Tập 22 Số 1
Abstract Background Environmental DNA (eDNA) is an effective tool for the
detection and monitoring of presence or absence of rare and invasive species.
These techniques have been extended to quantify biomass in vertebrates,
particularly in fish species. However, the efficacy of eDNA techniques to
quantify biomass in invertebrate species has rarely been examined. This study
tested whether eDNA coul...
Museomics and phylogenomics with protein-encoding ultraconserved elements illuminate the evolution of life history and phallic morphology of flesh flies (Diptera: Sarcophagidae)
AbstractBackgroundThe common name of the Flesh flies (Sarcophagidae) usually
relates them with organisms feeding on decomposing organic matter, although the
biology of one of the largest radiations among insects also includes predation,
coprophagy, and even kleptoparasitism. The question of whether the ancestor of
all sarcophagids was a predator or a decomposer, or in association to which host
hav...
Functional ecological convergence between the thylacine and small prey-focused canids
- 2021
Abstract Background Morphological convergence is a fundamental aspect of
evolution, allowing for inference of the biology and ecology of extinct species
by comparison with the form and function of living species as analogues. The
thylacine (Thylacinus cynocephalus), the iconic recently extinct marsupial, is
considered a classic example of convergent evolution with the distantly related
placental w...
Wolbachia-driven selective sweep in a range expanding insect species
- 2021
Abstract Background Evolutionary processes can cause strong spatial genetic
signatures, such as local loss of genetic diversity, or conflicting histories
from mitochondrial versus nuclear markers. Investigating these genetic patterns
is important, as they may reveal obscured processes and players. The maternally
inherited bacterium Wolbachia is among the most widespread symbionts in insects.
Wolba...
Molecular evolution and phylogenetic relationships of Ligusticum (Apiaceae) inferred from the whole plastome sequences
Tập 22 Số 1
Abstract Background The genus Ligusticum belongs to Apiaceae, and its taxonomy
has long been a major difficulty. A robust phylogenetic tree is the basis of
accurate taxonomic classification of Ligusticum. We herein used 26 (including 14
newly sequenced) plastome-scale data to generate reliable phylogenetic trees to
explore the phylogenetic relationships of Chinese Ligusticum. Results We found
that...
