Endemic Plant Species Conservation: Biotechnological Approaches [PDF]
Plants, 2020 Endemic plant species are usually more vulnerable to anthropogenic threats and natural changes and, therefore, hold a higher extinction risk. The preservation of these species is a major concern on a worldwide context and in situ protection alone will not guarantee their conservation.

High unexpected genetic diversity of a narrow endemic terrestrial mollusc [PDF]
PeerJ, 2017 The Iberian Peninsula has an extensive record of species displaying strong genetic structure as a result of their survival in isolated pockets throughout the Pleistocene ice ages. We used mitochondrial and nuclear sequence data to analyze phylogeographic

A New Endemic Thai Species of Argyreia (Convolvulaceae) [PDF]
Phytotaxa, 2014 A new species of Argyreia (Convolvulaceae) from Thailand is described and illustrated, and it is placed in relation to the known Thai species by inserting it into the key to Argyreia from the Flora of Thailand account. Argyreia suddeeana can be recognised by its unusually large, pendant flowers, arranged in capitate inflorescences with overlapping ...

SOIL AND PLANT RELATIONS OF SOME ORNITHOGALUM (ENDEMIC/NON ENDEMIC) SPECIES
Applied Ecology and Environmental Research, 2019 The study was carried out to determine the soil properties of the Ornithogalum L. species in the West Mediterranean Region of Turkey and their effects on plant morphology. Plant and soil samples concerning species Ornithogalum umbellatum L., O. oligophyllum E.D. Clarke, O. narbonense L., O. pyrenaicum L., O. lanceolatum Labill., O. pamphylicum (endemic)

Noncanonical Peloruside A Biosynthesis by an Uncultivated Verrucomicrobiota Symbiont
Angewandte Chemie, EarlyView.Noncanonical biochemistry of the peloruside PKS characterized in this work, comprising double bond generation by a noncanonical tridomain (blue), acetyl‐CoA recycling (orange), and proofreading systems (purple and yellow). The Z‐double bond is installed by TEB1 through O‐acetylation and acetate elimination. The acyl ligase PelB (AL, orange) selectively

Reinstatement of the Chinese endemic species Styrax zhejiangensis [PDF]
PhytoKeys, 2019 Styrax zhejiangensis has been treated as a synonym of S. macrocarpus. Examination of herbarium specimens and observation of wild living plants demonstrates that S. zhejiangensis is a distinct species and is clearly distinguishable from S. macrocarpus through its flowering phenology in which leaves and flowers open simultaneously, its smaller corolla ...

Artificial intelligence reveals environmental constraints on colour diversity in insects
Nature Communications, 2019 Deep learning has the potential to identify ecological relationships between environment and complex phenotypes that are difficult to quantify. Here, the authors use deep learning to analyse associations among elevation, climate and phenotype across ...

Weak gene–gene interaction facilitates the evolution of gene expression plasticity
BMC Biology, 2023 Background Individual organisms may exhibit phenotypic plasticity when they acclimate to different conditions. Such plastic responses may facilitate or constrain the adaptation of their descendant populations to new environments, complicating their ...

Invasibility and species richness of island endemic arthropods: a general model of endemic vs. exotic species [PDF]
Journal of Biogeography, 2005 AbstractAim This paper has two objectives. First, we examine how a variety of biotic, abiotic and anthropogenic factors influence the endemic and introduced arthropod richness on an oceanic island. Second, we look at the relationship between the endemic and introduced arthropod richness, to ask whether areas with high levels of endemic species richness

Advanced Science, EarlyView.Decoupling biological signals from unwanted variation in multi‑condition single‑cell RNA sequencing data remains challenging. CAPER disentangles condition‑associated biological effects from sample heterogeneity through matrix factorization, producing interpretable latent factors and a batch‑corrected expression matrix.
