Broad Fungal Compatibility and Seed Size May Facilitate Invasiveness in Two Asian Terrestrial Orchids Spathoglottis plicata and Arundina graminifolia

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Two Asian orchids, Arundina graminifolia and Spathoglottis plicata, are expanding into tropical regions worldwide, showing invasive behavior. In this study, we investigated the factors underlying their success. Both species—as all orchids—require fungal carbon to germinate, but S.

Resource recovery from black water

open access: yes, 2010
New sanitation systems based on separation at source offer a large potential for resource recovery from wastewater, e.g. energy and nutrients from black water and irrigation water from grey water. This review focuses on the components in source separated

Model experiment on heterotrophic denitrification vs. autotrophic anammox - quantifying collateral effects on the oceanic carbon cycle

open access: yes, 2015
The conversion of fixed nitrogen to N2 in suboxic waters is estimated to contribute roughly a third to total oceanic losses of fixed nitrogen and is hence understood to be of major importance to global oceanic production and, therefore, to the role of ...

The Partitioning Trend of Resources and Alpha-Amylase Enzyme Activity with Zinc Priming in Wheat (Triticum aestivum) Seed

open access: yesپژوهش‌های بذر ایران, 2017
The percentage and rate of germination and proper establishment of seedlings are important factors contributing to higher yield per unit area. As an essential element for plant growth and development, Zinc plays a critical role in many metabolic ...

Historical Contingency Drives Freshwater Microbial Community Assembly Across Successional Time

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Using a 60‐day full‐factorial reciprocal transplant microcosm experiment, we quantified the relative contributions of historical contingency, environmental selection, and dispersal limitation to freshwater bacterial community assembly. We show a pronounced temporal shift from early dispersal‐driven assembly to late‐stage dominance of historical ...

Climate Controls on Carbon Dioxide Fluxes in a High‐Elevation Grassland

open access: yesGlobal Change Biology Communications, Volume 1, Issue 2, June 2026.
Climate change is significantly influencing high‐elevation grasslands, possibly unbalancing CO2 exchanges and the sink‐source dynamics. Cumulated heat available for plant growth and vegetation cover were identified as the main controllers of phenological development and, via direct or mediated effects, of CO2 fluxes (ER and GPP).

Exploring Global Patterns of Trace Metal Limitation as a Regulator of the Distribution of Dominant Marine Phytoplankton Groups

open access: yesGlobal Change Biology Communications, Volume 1, Issue 2, June 2026.
By synthesizing decades of culture data with modern oceanographic datasets, we modelled trace metal limitation of phytoplankton. Our analysis reaffirms the critical role of iron but additionally highlights a significant, growing impact of zinc on the biological pump in future oceans.

Study on nitrogen removal in mixotrophic denitrification system driven by composite filter materials

open access: yesGongye shui chuli
NH4+-N in refinery wastewater is completely converted into NO3--N after biochemical treatment, resulting in extremely low C/N ratio in the effluent. The traditional heterotrophic denitrification processes require external carbon sources, which leads to ...

Low‐Head Dam Removal Restores Biofilm Structure but Not Function in a Temperate Stream

open access: yesInternational Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Barrier removal is a common stream restoration practice aimed at restoring longitudinal connectivity, yet its effects on biofilm structure and function, through alteration of near‐bed hydrodynamics, remain unclear. Using a space‐for‐time substitution approach, we assessed how the presence and removal of a low‐head dam affect biofilm structure ...

Acidophilic heterotrophs: basic aspects and technological applications

open access: yesFrontiers in Microbiology
Acidophiles comprise a group of microorganisms adapted to live in acidic environments. Despite acidophiles are usually associated with an autotrophic metabolism, more than 80 microorganisms capable of utilizing organic matter have been isolated from ...
