Diversity of Diptera families that pollinate Ceropegia (Apocynaceae) trap flowers: An update in light of new data and phylogenetic analyses [PDF]

, 2017
Pollination by flies (Diptera) has been important to the diversification and ecology of the flowering plants, but is poorly understood in contrast to pollination by other groups such as bees, butterflies and birds.

N2 fixation is linked to the ability to encroach in African savanna trees

Functional Ecology, Volume 40, Issue 2, Page 517-533, February 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Encroachment is a globally ubiquitous phenomenon, characterised by increasing indigenous tree densities in savanna and grassland. Encroachment has been attributed to rising atmospheric CO2 concentrations fertilising tree growth and shifting the competitive balance ...

Dietary DNA Metabarcoding From Animal Fecal Samples

Current Protocols, Volume 6, Issue 1, January 2026.
Abstract Fecal DNA metabarcoding is a powerful tool for examining animal diets with unprecedented resolution, offering insights into ecological patterns shaped by trophic interactions. As a result, dietary metabarcoding has become widely applied across ecology, evolution, behavior, and conservation.

Integrating Morphology and Chloroplast Genomics: A New East Asian Species of Aletris (Nartheciaceae) With Insights Into Regional Phylogeny and Evolution

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Based on morphological and chloroplast phylogenomic analyses, we describe Aletris medogensis as a new species endemic to the eastern Himalayas. Comparative genomics revealed structural variations, hypervariable markers, and signatures of positive selection in key genes, providing robust evidence for species delimitation and insights into the ...

Reexamination of a putative diploid hybrid Taxon using genetic evidence: The distinctiveness of Phlox pilosa subsp. deamii (Polemoniaceae) [PDF]

, 2014
Premise of research. A number of recent studies have shown that hybridization plays a key role in the evolution of plants and can lead to the development of genetic and taxonomic novelty, even without a change in ploidy level.

Structural Characteristics, Comparative Analyses, and Conservation Significance of the Complete Chloroplast Genome of the Critically Endangered Lithocarpus yongfuensis (Fagaceae)

Ecology and Evolution, Volume 16, Issue 1, January 2026.
We assembled and annotated the complete chloroplast genome of L. yongfuensis. The genome structure, gene content, and phylogenetic relationships were analyzed, providing new insights into the species' evolutionary history. These findings offer valuable genomic resources for future studies on taxonomy, conservation, and molecular breeding of L ...

Филогенетическое положение Phlojodicarpus villosus (Apiaceae) на основе анализа последовательностей ITS и trnH-psbA

Turczaninowia, 2021
В международных открытых генетических базах данных отсутствуют сведения о нуклеотидных последовательностях для Phlojodicarpus villosus. Этот вид сосудистых растений представлен на Урале изолированными реликтовыми популяциями и включен в региональные Красные книги.
