Structure and dynamics of a clonal plant population: Classical model results in a non-classic formulation

Adaptation on the ground and beneath: does the local population maximize its λ1?

“…In contrast to our former Calamagrostis projects (Ulanova et al, 2002(Ulanova et al, , 2008Logofet et al, 2006;Logofet, 2008Logofet, , 2013c, there exists a reproduction link (g 2 2 ! g 1 1 in Fig.…”

“…The kind of data we have been dealing with in a number of Calamagrostis case studies (Ulanova et al, 2002(Ulanova et al, , 2008Logofet et al, 2006;Logofet, 2013c) was called 'identified individuals' by Caswell (2001, p. 134). When a woodreed population grows fast due to vegetative propagation, the age-stage status of each individual plant (in a sample plot) can be determined (with the changes monitored over successive years) reliably from the morphology of its above-ground part, but the pointer to its parent plant (the rhizome that the individual plant has developed from) is reliably hidden beneath.…”

Ontogeny, allometry and architecture of Psychotria tenuinervis (Rubiaceae)

“…Structural differences during ontogenetic development in different plant groups involve the presence/absence of cotyledons, ramification patterns, stem type, stipe, reproductive structures, and the root system (Souza et al 2000(Souza et al , 2003Lienert & Fischer 2003;Logofet et al 2006;Miranda--Melo et al 2007;Bernacci et al 2008;Fidelis et al 2008;Schmucki & de Blois 2009). Morphological changes during ontogenetic development can be evaluated through the study of plant architecture (Bell 1991;Barthélémy & Caraglio 2007), which describes the inherited branching pattern of species, such as their characteristics related to the direction of growth, activity in time and destiny (Barthélémy & Caraglio 2007;León Enriquez et al 2008).…”

“…The allometric relationship between height and stem diameter indicates the amount of support that the plant requires within given environmental conditions (Claussen & Maycock 1995). Morphometric characteristics include total height; stem diameter; number and size of the leaves; rosette diameter; and number of branches (Souza et al 2000(Souza et al , 2003Lienert & Fischer 2003;Logofet et al 2006;Miranda-Melo et al 2007;Bernacci et al 2008;Fidelis et al 2008;Schmucki & de Blois 2009).…”

Multistability in dynamic models of migration coupled populations with an age structure

“…Следует отметить, что динамика метапопуляции описывается обобщенной системой из связанных систем отображений, если ее локальные популяции имеют сложное внутреннее устройство, например, состоят из нескольких возрастных классов [1,3,4,6,16]. В этом случае локальной динамике соответствует система отображений, учитывающая особенности субпопуляции, а миграционная связь описывается путем добавления аддитивных членов к правым частям уравнений [5,17].…”
