In this preliminary screening study, we tested the phytoextraction potential of nine Canadian native/well-adapted plant species on a soil highly polluted by trace elements (TE) from a copper refinery. Plant physiological parameters and soil cover index were monitored for a 12-week period. At the end of the trial, biomass yield, bioconcentration (BFC) and translocation (TF) factors for the main TE as well as phytoextraction potential were determined. Most plants were severely injured by the high pollution levels, showing symptoms of toxicity including chlorosis, mortality and very low biomass yield. However, Indian mustard showed the highest selenium extraction potential (65 mg m(-2)), even under harsh growing conditions. Based on our results, tall fescue and ryegrass, which mainly stored As, Cu, Pb and Zn within roots, could be used effectively for phytostabilization.

Mixed-species forests are proposed to enhance tree resistance and resilience to drought. However, growing evidence shows that tree species richness does not consistently improve tree growth responses to drought. The underlying mechanisms remain uncertain, especially under unprecedented multiyear droughts.

Background: The coevolutionary arms race between echolocating bats and tympanate moths has driven the evolution of ultrasound-mediated escape behaviors in moths. Bat-emitted ultrasonic pulses vary in sound intensity and temporal structure, with pulse repetition rate (PRR) which intrinsically encode critical information about predation risk, i.e.

Hayata 1916 is a unique bamboo species endemic to Taiwan, typically found at elevations ranging from 500 to 1,500 meters. This study provides a detailed analysis of the complete chloroplast genome of for the first time. The genome spans 139,664 base pairs (bp) and consists of a large single-copy (LSC) region of 83,192 bp, a small single-copy (SSC) region of 12,869 bp, and two inverted repeat (IR) regions, each 21,798 bp in length.

Arbuscular mycorrhizal fungi (AMF) play a crucial role in disease control by establishing symbiotic relationships with plant roots. AMF improve salinity tolerance in plants by regulating the Na/K ratio through selective ion transport and mediate osmotic regulation by inducing the accumulation of osmotic-compatible solutes such as glycine betaine and proline to enable plant cells to maintain water content and the metabolic balance. AMF can also activate antioxidant defense responses by stimulating enzymes that protect plant cells from harmful oxidation and pathological infections.

DNA fecal metabarcoding has revolutionized the field of herbivore diet analyses, offering deeper insight into plant-herbivore interactions and more reliable ecological inferences. However, due to PCR amplification bias, primer selection has a major impact on the validity of these inferences and insights. Using two pooling approaches on four mock communities and a case study examining diets of four large mammalian herbivores (LMH), we evaluated the efficacy of two primer pairs targeting the internal transcribed spacer 2 (ITS2) region: the widely used ITS-S2F/ITS4 pair and the UniPlant F/R pair, designed specifically for DNA metabarcoding.
