Fumigant Activity of Tridax procumbens (Asterales: Asteraceae) Essential Oil Against Sitophilus zeamais (Coleoptera: Curculionidae) and Its Effects on Thai Rice Seed Germination

open access: yesJournal of entomological science, 2022
Fumigant activity of the essential oil extracted from Tridax procumbens L. (Asterales: Asteraceae) by water distillation was assessed against Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae), together with its effect on the germination of three

Extrapolating demography with climate, proximity and phylogeny: approach with caution [PDF]

open access: yes, 2016
Plant population responses are key to understanding the effects of threats such as climate change and invasions. However, we lack demographic data for most species, and the data we have are often geographically aggregated.

Ancestral Reconstruction and Investigations of Genomic Recombination on some Pentapetalae Chloroplasts

open access: yesJournal of Integrative Bioinformatics, 2019
In this article, we propose a semi-automated method to rebuild genome ancestors of chloroplasts by taking into account gene duplication. Two methods have been used in order to achieve this work: a naked eye investigation using homemade scripts, whose ...

The complete chloroplast genome sequence of Helwingia himalaica (Helwingiaceae, Aquifoliales) and a chloroplast phylogenomic analysis of the Campanulidae [PDF]

open access: yesPeerJ, 2016
Complete chloroplast genome sequences have been very useful for understanding phylogenetic relationships in angiosperms at the family level and above, but there are currently large gaps in coverage.

The carboxypeptidase B and carbonic anhydrase genes play a reproductive regulatory role during multiple matings in Ophraella communa

open access: yesFrontiers in Molecular Biosciences, 2023
Seminal fluid proteins (SFPs) are key factors in sexual reproduction and are transferred to females during mating with sperm. SFPs have a nutritional value because they protect and activate sperm storage and release to optimize fecundity.

Investigating Anthropogenic and Social Influences on Diet of Semi-Urban Vervet Monkeys Using DNA Metabarcoding. [PDF]

open access: yesEcol Evol
We used eDNA metabarcoding of faecal samples to quantify the dietary composition of two vervet monkey populations in a semi‐urban environment in South Africa over a 4‐month period, and compared these results with visual observations. We found that both methods yielded similar results, but eDNA metabarcoding revealed a greater diversity of consumed taxa.

Assessing risks and benefits of floral supplements in conservation biological control [PDF]

open access: yes, 2010
The use of flowering field margins is often proposed as a method to support biological control in agro-ecosystems. In addition to beneficial insects, many herbivores depend on floral food as well.
