Dynamic growth model for oak stands in Moscow, Russia [PDF]

open access: yesE3S Web of Conferences, 2023
The most objective information about the state of Moscow’s forests is provided by long-term observation data on permanent trial plots. Such data makes it possible to identify changes in forest stands under the influence of recreationists, environmental ...

Novel models for simulating maize growth based on thermal time and photothermal units: Applications under various mulching practices

open access: yesJournal of Integrative Agriculture, 2023
Maize (Zea mays L.) is one of the three major food crops and an important source of carbohydrates for maintaining food security around the world. Plant height (H), stem diameter (SD), leaf area index (LAI) and dry matter (DM) are important growth ...

Trait-Based Model Reproduces Patterns of Population Structure and Diversity of Methane Oxidizing Bacteria in a Stratified Lake

open access: yesFrontiers in Environmental Science, 2022
In stratified lakes, methane oxidizing bacteria are critical methane converters that significantly reduce emissions of this greenhouse gas to the atmosphere. Efforts to better understand their ecology uncovered a surprising diversity, vertical structure,

Age, Growth and Otolith Microstructure of the Spotted Lanternfish Myctophum punctatum Rafinesque 1810

open access: yesJournal of Marine Science and Engineering, 2021
This study investigated, for the first time, the age and growth of the spotted lanternfish Myctophum punctatum through an analysis of otolith microstructure. A total of 377 individuals were collected from the Strait of Messina (central Mediterranean Sea),

MODIFICATION OF THE COBWEB MODEL INTO GENERALIZED LOGISTIC EQUATION FOR THE WHEAT PRICE ANALYSIS

open access: yesEkonomika Poljoprivrede (1979), 2023
In the paper we constructed the new wheat growth model, based on the generalized logistic equation. Starting from the theoretical framework of the cobweb model, we adapted generalized logistic equation to better fit the real data of wheat prices ...

Shifting seasonality of annual growth through ontogeny for red deer at northern latitudes

open access: yesEcosphere, 2023
Large mammals at northern latitudes show annual cycles of body mass gain in summer and body mass loss in winter. The amplitude and seasonal timing of these cycles may vary through ontogeny depending on trade‐offs toward investments in structural growth ...

Growth of the Mesopelagic Fish Vinciguerria attenuata (Cocco, 1838) in the Strait of Messina (Central Mediterranean Sea)

open access: yesJournal of Marine Science and Engineering, 2023
The age and growth of the slender lightfish Vinciguerria attenuata are investigated for the first time by the analysis of otolith microstructure. A total of 242 individuals (standard length range = 15.3–39.0 mm) are collected from the Strait of Messina ...

The Effect of the Shear Flow on the Morphological Pattern of Particles in an Undercooled Melt

open access: yesMetals, 2022
The effect of shear flow on the morphological pattern of particles in an undercooled melt is studied by using the asymptotic method. The mathematical model of the particle includes the anisotropic interface kinetic undercooling.
