Ann Bot

November 2024

Forest Biology Center, Institute of Environmental Biology, Faculty of Biology, Adam Mickiewicz University, ul. Uniwersytetu Poznańskiego 6, 61-614 Poznan, Poland.

Background And Aims: Both plants and animals display considerable variation in their phe- notypic traits as they grow. This variation helps organisms to adapt to specific challenges at different stages of development. Masting, the variable and synchronized seed production across years by a population of plants, is a common reproductive strategy in perennial plants that can enhance reproductive efficiency through increasing pollination efficiency and decreasing seed predation.

A plausible, but largely unexplored reason for many weed biocontrol agents failing to establish or being ineffective, could involve abiotically induced changes to an invasive plants' biochemical phenotype and consequent enhanced herbivore resistance. Considerable literature demonstrates that chemically altered plant phenotypes can impair insect life history performance. Heather beetle, (Lochmaea suturalis), introduced to control invasive heather (Calluna vulgaris) in New Zealand (NZ) was difficult to establish and displays variable effectiveness.

Article Synopsis
  • Plants adapt to environmental stress by altering growth and development, with calcium (Ca) playing a crucial role as a secondary messenger in response to these stressors.
  • The bi-directional dual-flow RootChip (bi-dfRC) platform was used to study root growth and defense signaling by simulating salinity stress with sodium chloride (NaCl) treatment, revealing a concentration-dependent calcium burst that spreads from the stele to the root tip.
  • Research also demonstrated that salinity impacts root growth differently depending on root architecture, with varying responses observed and novel insights gained into root force sensing through engineered microfluidic channels.

Priority effects, where the order and timing of species arrival influence the assembly of ecological communities, have been observed in a variety of taxa and habitats. However, the genetic and molecular basis of priority effects remains unclear, hindering a better understanding of when priority effects will be strong. We sought to gain such an understanding for the nectar yeast Metschnikowia reukaufii commonly found in the nectar of our study plant, the hummingbird-pollinated Diplacus (Mimulus) aurantiacus.

Faculty of Forestry and Wood Sciences, Czech University of Life Sciences, Suchdol, 165 00 Prague, Czechia; USDA Forest Service Northern Research Station, Morgantown, WV 26505, USA.

Article Synopsis
  • Globalization has led to an increase in invasive insect species, resulting in significant losses of ecosystem services, with plant invasions creating environments that favor non-native herbivores.
  • A study of 5,839 non-native insect species revealed that herbivores make up a larger portion (52.4%) of these species compared to global fauna (38.4%), while other groups like predators and detritivores are less represented.
  • Findings indicate that herbivore invasions tend to follow plant invasions by about 80 years, suggesting that plant invasions play a crucial role in the spread of non-native insect populations.

Building pangenome graphs.

Nat Methods

November 2024

Department of Genetics, Genomics and Informatics, University of Tennessee Health Science Center, Memphis, TN, USA.

Pangenome graphs can represent all variation between multiple reference genomes, but current approaches to build them exclude complex sequences or are based upon a single reference. In response, we developed the PanGenome Graph Builder, a pipeline for constructing pangenome graphs without bias or exclusion. The PanGenome Graph Builder uses all-to-all alignments to build a variation graph in which we can identify variation, measure conservation, detect recombination events and infer phylogenetic relationships.

Fabrication of polyoxometalate dispersed cobalt oxide nanowires for electrochemically monitoring superoxide radicals from Hela cell mitochondria.

Talanta

January 2025

Henan International Joint Laboratory of Medicinal Plants Utilization, College of Chemistry and Molecular Sciences, Henan University, Zhengzhou, 450046, China. Electronic address:

An ultrasensitive electrochemical sensor is constructed by electrostatically adsorbing negatively charged hourglass-shape Cu-Polyoxometalate (POM) onto a positively charged CoO nanowires modified carbon cloth. The petaloid CoO nanowires have a large specific surface area that can well disperse open-structured Cu-POM to form Cu-POM@CoONWs@CC, which can maximumly expose catalytic active centers (Co and Cu) and accelerate mass/charge transfer. In addition to the above advantages, the excellent electron exchange ability of Cu-POM and good conductivity of CoONWs@CC endow the sensor with good detection capability to HO including a linear detection range of 0.

Tidal stream environments are important areas of marine habitat for the development of marine renewable energy (MRE) sources and as foraging hotspots for megafaunal species (seabirds and marine mammals). Hydrodynamic features can promote prey availability and foraging efficiency that influences megafaunal foraging success and behaviour, with the potential for animal interactions with MRE devices. Uncrewed aerial vehicles (UAVs) offer a novel tool for the fine-scale data collection of surface turbulence features and animals, which is not possible through other techniques, to provide information on the potential environmental impacts of anthropogenic developments.
