Generalized Mechanism Model for Ecosystem Hysteresis

Advanced Science, EarlyView.
A simplified model examines ecosystem transitions into alternative states after disturbances by leveraging positive and negative feedbacks. It identifies critical tipping points and quantifies hysteresis. Tests conducted on lakes, grasslands, and pitcher‐plant leaves align closely with empirical data and enable the prediction of recovery trajectories ...

Prototypical Biomass-Fired Micro-Cogeneration Systems—Energy and Ecological Analysis [PDF]

Energies, 2020
Combined heat and power systems dedicated to micro-scale applications are currently increasing in popularity. The use of such systems is beneficial from the standpoint of increasing the usage of renewable energy, increasing energy efficiency and reducing CO2 emissions into the atmosphere. This paper shows two examples of prototypical micro-cogeneration

WATCHING GRASS GROW- A PILOT STUDY ON THE SUITABILITY OF PHOTOGRAMMETRIC TECHNIQUES FOR QUANTIFYING CHANGE IN ABOVEGROUND BIOMASS IN GRASSLAND EXPERIMENTS [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
Grassland ecology experiments in remote locations requiring quantitative analysis of the biomass in defined plots are becoming increasingly widespread, but are still limited by manual sampling methodologies. To provide a cost-effective automated solution

Long‐Term Active Rather than Passive Restoration Promotes Soil Organic Carbon Accumulation by Alleviating Microbial Nitrogen Limitation in an Extremely Degraded Alpine Grassland

Advanced Science, EarlyView.
Active restoration increases soil organic carbon stocks by reducing microbial nitrogen limitation. Nitrogen availability promotes particulate to mineral‐associated organic carbon conversion by reducing microbial carbon use efficiency. Passive restoration has no effect on soil organic carbon stocks.

Precision Editing of NLRS Improves Effector Recognition for Enhanced Disease Resistance

Advanced Science, EarlyView.
Precision engineering of plant NLR immune receptors enables rational design of enhanced pathogen resistance through mismatched pairing, domain swapping, and targeted mutagenesis. These approaches achieve multi‐fold expansion in recognition breadth while minimizing autoimmunity risks and fitness penalties.

Manta munchies: plankton dynamics and feeding behaviour of reef manta rays (Mobula alfredi) around D’Arros Island in the Seychelles

Frontiers in Marine Science
The reef manta ray (Mobula alfredi) is a threatened filter-feeding elasmobranch that requires immediate management and protection across large parts of its range. Despite being well-studied, a detailed understanding of their feeding ecology, which shapes

Scaling up the curvature of mammalian metabolism

Frontiers in Ecology and Evolution, 2014
A curvilinear relationship between mammalian metabolic rate and body size on a log-log scale has been adopted in lieu of thelongstanding concept of a 3/4 allometric relationship (Kolokotrones et al. 2010).

Ecological pellets from brown coal and biomass

Acta Montanistica Slovaca, 2007
One way of renewable energy sources applications in the Czech republic is a cultivation of biomass plants. After the biomass reformation, it is possible to add it to palletizing mixes with coal and delulfurisative additives. Possibilities of brown coal of palletizing with biomass adds were tested recently.
