Wooded meadows (also named wood-meadows, park meadows, etc.) are ecosystems in temperate forest regions. They are sparse natural stands with a regularly mowed herbaceous layer.

Contents

While frequent throughout Europe during the Medieval period and before, wooded meadows have largely disappeared. Wooded meadows originated with the practices of hunter-gatherer communities. They were important in terms of social organization around a natural resource and determined much of the community's interactions with the natural world. [1] In the early 20th century, wooded meadows were used for fruit cultivation in Sweden; however, their prevalence has decreased substantially due to changes in land management and a movement toward more intensive types of agroecosystems. [2] The more typical, calcicolous[ further explanation needed ] wooded meadows are common around the Baltic Sea. [3]

Wooded meadows have high species richness. In some of the current Estonian wooded meadows, world-record species densities have been recorded (up to 76 species of vascular plants per square meter). [4]

Semiotics is the systematic study of sign processes and the communication of meaning. In semiotics, a sign is defined as anything that communicates intentional and unintentional meaning or feelings to the sign's interpreter.

<span class="mw-page-title-main">Biodiversity</span> Variety and variability of life forms

Biodiversity is the variety and variability of life on Earth. It can be measured on various levels. There is for example genetic variability, species diversity, ecosystem diversity and phylogenetic diversity. Diversity is not distributed evenly on Earth. It is greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than one-fifth of Earth's terrestrial area and contain about 50% of the world's species. There are latitudinal gradients in species diversity for both marine and terrestrial taxa.

<span class="mw-page-title-main">Grassland</span> Area with vegetation dominated by grasses

A grassland is an area where the vegetation is dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on Earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area.

<span class="mw-page-title-main">Alvar</span> Limestone-based biological environment

An alvar is a biological environment based on a limestone plain with thin or no soil and, as a result, sparse grassland vegetation. Often flooded in the spring, and affected by drought in midsummer, alvars support a distinctive group of prairie-like plants. Most alvars occur either in northern Europe or around the Great Lakes in North America. This stressed habitat supports a community of rare plants and animals, including species more commonly found on prairie grasslands. Lichen and mosses are common species. Trees and bushes are absent or severely stunted.

<span class="mw-page-title-main">Meadow</span> Open habitat vegetated primarily by non-woody plants

A meadow is an open habitat or field, vegetated by grasses, herbs, and other non-woody plants. Trees or shrubs may sparsely populate meadows, as long as these areas maintain an open character. Meadows can occur naturally under favourable conditions, but are often artificially created from cleared shrub or woodland for the production of hay, fodder, or livestock. Meadow habitats, as a group, are characterized as "semi-natural grasslands", meaning that they are largely composed of species native to the region, with only limited human intervention.

Juri Lotman was a prominent Russian-Estonian literary scholar, semiotician, and historian of Russian culture, who worked at the University of Tartu. He was elected a member of the British Academy (1977), Norwegian Academy of Science and Letters (1987), Royal Swedish Academy of Sciences (1989) and Estonian Academy of Sciences (1990). He was a founder of the Tartu–Moscow Semiotic School. The number of his printed works exceeds 800 titles. His archive which includes his correspondence with a number of Russian and Western intellectuals, is immense.

Biosemiotics is a field of semiotics and biology that studies the prelinguistic meaning-making, biological interpretation processes, production of signs and codes and communication processes in the biological realm.

Zoosemiotics is the semiotic study of the use of signs among animals, more precisely the study of semiosis among animals, i.e. the study of how something comes to function as a sign to some animal. It is the study of animal forms of knowing.

He is also known for his work in the development of long-time nuclear waste warning messages, in which he worked with the Human Interference Task Force to create methods for keeping the inhabitants of Earth away from buried nuclear waste that will still be hazardous 10,000 or more years in the future.

<span class="mw-page-title-main">Agricultural biodiversity</span> Agricultural concept

Agricultural biodiversity or agrobiodiversity is a subset of general biodiversity pertaining to agriculture. It can be defined as "the variety and variability of animals, plants and micro-organisms at the genetic, species and ecosystem levels that sustain the ecosystem structures, functions and processes in and around production systems, and that provide food and non-food agricultural products.” It is managed by farmers, pastoralists, fishers and forest dwellers, agrobiodiversity provides stability, adaptability and resilience and constitutes a key element of the livelihood strategies of rural communities throughout the world. Agrobiodiversity is central to sustainable food systems and sustainable diets. The use of agricultural biodiversity can contribute to food security, nutrition security, and livelihood security, and it is critical for climate adaptation and climate mitigation.

<span class="mw-page-title-main">Secondary forest</span> Forest or woodland area which has re-grown after a timber harvest

A secondary forest is a forest or woodland area which has regenerated through largely natural processes after human-caused disturbances, such as timber harvest or agriculture clearing, or equivalently disruptive natural phenomena. It is distinguished from an old-growth forest, which has not recently undergone such disruption, and complex early seral forest, as well as third-growth forests that result from harvest in second growth forests. Secondary forest regrowing after timber harvest differs from forest regrowing after natural disturbances such as fire, insect infestation, or windthrow because the dead trees remain to provide nutrients, structure, and water retention after natural disturbances. Secondary forests are notably different from primary forests in their composition and biodiversity; however, they may still be helpful in providing habitat for native species, preserving watersheds, and restoring connectivity between ecosystems.

<span class="mw-page-title-main">Species richness</span> Variety of species in an ecological community, landscape or region

Species richness is the number of different species represented in an ecological community, landscape or region. Species richness is simply a count of species, and it does not take into account the abundances of the species or their relative abundance distributions. Species richness is sometimes considered synonymous with species diversity, but the formal metric species diversity takes into account both species richness and species evenness.

<span class="mw-page-title-main">Wet meadow</span>

A wet meadow is a type of wetland with soils that are saturated for part or all of the growing season which prevents the growth of trees and brush. Debate exists whether a wet meadow is a type of marsh or a completely separate type of wetland. Wet prairies and wet savannas are hydrologically similar.

On January 1, 2005 it was merged into the Institute of Agricultural and Environmental Sciences.

Ecosemiotics is a branch of semiotics in its intersection with human ecology, ecological anthropology and ecocriticism. It studies sign processes in culture, which relate to other living beings, communities, and landscapes. Ecosemiotics also deals with sign-mediated aspects of ecosystems.
