Greater species diversity of plants (i.e. diversity within a single species) increases overall crop yield (synthesis of 575 experimental studies). [148] Although another review of 100 experimental studies reported mixed evidence. [149] Greater species diversity of trees increases overall wood production (synthesis of 53 experimental studies). [150]
Food biodiversity is "the diversity of plants, animals and other organisms used for food, covering the genetic resources within species, between species and provided by ecosystems." [ 15 ] Historically at least 6,000 plant species and numerous animal species have been used as human food.
Crop diversity or crop biodiversity is the variety and variability of crops, plants used in agriculture, including their genetic and phenotypic characteristics. It is a subset of a specific element of agricultural biodiversity .
In seed plants (gymnosperms and flowering plants), the sporophyte forms most of the visible plant, and the gametophyte is very small. Flowering plants reproduce sexually using flowers, which contain male and female parts: these may be within the same ( hermaphrodite ) flower, on different flowers on the same plant , or on different plants .
Alpha diversity refers to diversity within a particular area, community or ecosystem, and is measured by counting the number of taxa within the ecosystem (usually species) [14] Beta diversity is species diversity between ecosystems; this involves comparing the number of taxa that are unique to each of the ecosystems.
A megadiverse country must have at least 5,000 species of endemic plants and must border marine ecosystems. List of megadiverse countries In ...
Biodiversity is the total diversity of species present in an area at all levels of biological organization. [1] It is characterized by heterogeneous habitats that support the diverse ecological structure. [1] In agricultural areas, biodiversity decreases as varying landscapes are lost and native plants are replaced with cultivated crops. [1]
