AI Article Synopsis
- Bryophytes are effective at absorbing heavy metals and can grow in contaminated soils, but the details of how they do this are not well understood.
- The study focused on the effects of excess nickel (Ni) on two liverwort species, Asterella wallichiana and Plagiochasma appendiculatum, examining how it impacts their reproductive organs, population viability, and overall morphology.
- Results showed that P. appendiculatum was less negatively affected by nickel excess compared to A. wallichiana, providing new insights into how these plants respond to heavy metal stress.
Article Abstract
Bryophytes are potent metal absorbers, thriving well on heavy metal (HM)-polluted soils. Mechanisms controlling uptake, compartmentalization and impacts of HMs on bryophytes life cycle are largely unknown. The current study is an effort to decipher mechanisms of nickel (Ni) excess-induced effects on the phenological events of two bryophytes, Asterella wallichiana and Plagiochasma apendiculatum growing in natural habitats. Observations revealed Ni-excess induced negative impacts on abundance, frequency of occurrence of reproductive organs, population viability and morphological traits, spore viability and physiological attributes of both the liverworts. Results led us conclude that P. appendiculatum survived better with the lowest impact on its life cycle events than A. wallichiana under Ni excess in natural habitats. Our findings collectively provide insights into the previously unknown mechanisms of Ni-induced responses in liverworts with respect to phenological attributes, as well as demonstrate the potential of P. appendiculatum to survive better in Ni excess habitats.

With an increasing concentration of microplastics (MPs) in every biome, laboratories with a focus on creating histology slides from resin-embedded specimens could be partially responsible for expanding the emission of microscopic resinous particles into the environment. With current research elucidating harmful health impacts from MPs, releasing them incautiously is arguably unethical and, in the near future, plausibly illegal. The Orthopedic Bioengineering Research Laboratory (OBRL) is in Colorado, a state known not only for its natural beauty but also for its increasing number of legislative amendments aimed at reducing plastic pollution.

Objective: The public health nutrition workforce is well-placed to contribute to bold climate action, however tertiary educators are seeking practical examples of how to adequately prepare our future workforce. This study examines the responses of university students engaged in a co-designed planetary health education workshop as part of their public health nutrition training.
Design: A mixed-methods approach was used to collect and interpret student responses to four interactive tasks facilitated during an in-person workshop.
Climate Change Drives Changes in the Size and Composition of Fungal Communities Along the Soil-Seedling Continuum of Schima superba.

Plant microbiomes have a major influence on forest structure and functions, as well as tree fitness and evolution. However, a comprehensive understanding of variations in fungi along the soil-plant continuum, particularly within tree seedlings, under global warming is lacking. Here, we investigated the dynamics of fungal communities across different compartments (including bulk soil and rhizosphere soil) and plant organs (including the endosphere of roots, stems and leaves) of Schima superba seedlings exposed to experimental warming and drought using AccuITS absolute quantitative sequencing.

Non-indigenous dung beetle (Coleoptera: Scarabaeoidea) species in North America are important contributors to ecosystem functions, particularly in pasture-based livestock systems. Despite the significant body of research surrounding non-indigenous (and often invasive) dung beetles in agricultural contexts, there has been minimal study concerning the impact that these species may have on indigenous dung beetle populations in natural environments. Here we examine the possible impact of the introduced dung beetle on indigenous dung beetle populations via use of indigenous mammal dung.

Matrix population models are essential tools in conservation biology, offering key metrics to guide species management and conservation planning. However, the development of these models is often limited by insufficient life history data, particularly for non-charismatic species. This study addresses this gap by using life history data from FishBase and the FishLife R package, complemented by size-dependent natural mortality estimates, to parameterize age-structured matrix population models applicable to most fish species.
