Structure and development of the egg of the glossiphoniid leech Theromyzon rude: Characterization of developmental stages and structure of the early uncleaved egg
(1987)
Some aspects of the reproductive biology of the glossiphoniid leech, Theromyzon rude, under laboratory conditions, and the staging and structure of its uncleaved egg were studied. Sexually mature animals form breeding ...
Persistence for a two-stage reaction-diffusion system
(MDPI, 2020)
In this article, we study how the rates of diffusion in a reaction-diffusion model for a stage structured population in a heterogeneous environment affect the model's predictions of persistence or extinction for the ...
Persistence for a two-stage reaction-diffusion system
(MDPI, 2020)
In this article, we study how the rates of diffusion in a reaction-diffusion model for a stage structured population in a heterogeneous environment affect the model's predictions of persistence or extinction for the ...
Spatial dynamics of a population with stage-dependent diffusion
(Elsevier B.V., 2015-05-01)
We explore the spatial dynamics of a population whose individuals go through life stages with very different dispersal capacities. We model it through a system of partial differential equations of the reaction-diffusion ...
A two-sex matrix population model to represent harem structure
(American Institute of Mathematical Sciences, 2016-10)
Population dynamic models often include males in the calculation of population change, but even in those cases males have rarely been introduced to represent polygyny (harem social structure), where it is particularly ...
Plant beneficial rhizobacteria community structure changes through developmental stages of peanut and maize
(Elsevier, 2021-09)
Our objective in this study was to analyze the structure of the rhizobacterial community during different growth stages of peanut and maize plants. Microcosm assays were performed using pots containing unsterile soil from ...
Population dynamics, life stage and ecological modeling in Chrysomya albiceps (Wiedemann) (Diptera: Calliphoridae)
(Entomological Soc Brasil, 2011-03-01)
In this study we investigated the population dynamics of Chrysomya albiceps (Wiedemann) with laboratory experiments, employing survival analysis and stage structure mathematical models, emphasizing survival among life ...
