Background: The Pacific Region has the highest density of naturalised plant species worldwide, which makes it an important area for research on the ecology, evolution and biogeography of biological invasions. While different data sources on naturalised plant species exist for the Pacific, there is no taxonomically and spatially harmonised database available for different subsets of species and islands. A comprehensive, accessible database containing the distribution of naturalised vascular plant species in the Pacific will enable new basic and applied research for researchers and will be an important information source for practitioners working in the Region.
New Information: Here, we present PacIFlora, an updated and taxonomically standardised list of naturalised species, their unified nativeness, cultivation and invasive status and their distribution across the Pacific Ocean, including harmonised location denoination. This list is based on the two largest databases on naturalised plants for the Region, specifically the Pacific Island Ecosystems at Risk (PIER) and the Global Naturalised Alien Flora (GloNAF) databases. We provide an outlook for how this database can contribute to numerous research questions and conservation efforts.

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.
