Dissolutions of commons were rare prior to 1800 and peaked around 1850, comparable to a mass extinction in biology. Analyses of > 400 Dutch commons over more than a millennium (between the 9 th and the 20 th century) uncovered that most commons originated between 12, and that there was a particularly high rate of evolution during 1300–1550, a pattern intermediate to gradualism and punctuated equilibrium in biological evolution. We apply an interdisciplinary approach and address these issues from an eco-evolutionary perspective.
#Clumped dispersio drivers
Despite growing scientific interests, analyses of commons evolution and temporal dynamics are rare and drivers of change (birth, adaptation, dissolution) remain obscure. The distribution of species in groups, groups of species, or groups of species in groups, or groups of species in groups, or groups of species in groups, or groups of species in groups, or groups of species in groups, or groups of species.Historical commons represent self-governed governance regimes that regulate the use and management of natural and man-made shared resources.

Chorology is the discipline in charge of establishing the distribution of species, while biogeography is that which studies the climatic, geological, geographical or historical factors that determine such distribution, the communities, their dynamics, and evolution. The area where a species is found can be represented by a species distribution map. Species distribution should not be confused with dispersal, which is the movement of individuals from their area of origin or centers of high density to other locations. Species distribution modes are the different ways in which a biological taxon may be spatially arranged in its biogeographic range. Finally, habitat selection is closely related to the evolution and heritability of structures capable of providing adequate information and, of course, of having the capacity to change over time in the face of the possibility of environmental alterations or the opening of new environments. In this sense, it is considered that natural selection will favor individuals whose sensory systems allow them to identify suitable habitats in which they can establish themselves and develop successfully, for example, those that allow them to identify the odor of a certain food or the substrate on which they should or should not oviposit systems that identify gradients of humidity, temperature or incidence of sunlight others that alert them to the presence of predators and competitors, or systems that allow them to identify the presence of a certain type of substrate for fixation. – Habitat selection mechanisms: these are related to the behavioral patterns that lead an organism and a population to “choose” whether or not to live in a given environment. See also What are examples of organismal ecology? Understanding dispersal and the consequences for both species-level evolutionary strategies and ecosystem-level processes requires understanding the type of dispersal, the dispersal range of a given species, and the dispersal mechanisms involved.
#Clumped dispersio Patch
By simply moving from one habitat patch to another, the dispersal of an individual has consequences not only for individual fitness, but also for population dynamics, population genetics, and species distribution. The act of dispersal involves three phases: departure, transfer, settlement, and there are different fitness costs and benefits associated with each of these phases. Technically, dispersal is defined as any movement that has the potential to lead to gene flow.

Dispersal is also used to describe the movement of propagules such as seeds and spores.

Biological dispersal refers to both the movement of individuals (animals, plants, fungi, bacteria, etc.) from their place of birth to their site of reproduction (‘natal dispersal’), and the movement from one site of reproduction to another (‘reproductive dispersal’).
