Distribution and Dispersion00:54

Distribution and Dispersion

25.8K
To understand intra-specific interactions in populations, scientists measure the spatial arrangement of species individuals. This geographic arrangement is known as the species distribution or dispersion. Highly territorial species exhibit a uniform distribution pattern, in which individuals are spaced at relatively equal distances from one another. Species that are highly tied to particular resources, such as food or shelter, tend to concentrate around those resources, and thus exhibit a...

Pollination and Flower Structure02:40

Pollination and Flower Structure

79.8K
Flowers are the reproductive, seed-producing structures of angiosperms. Typically, flowers consist of sepals, petals, stamens, and carpels. Sepals and petals are the vegetative flower organs. Stamens and carpels are the reproductive organs.

Morphogenesis02:19

Morphogenesis

30.7K
Plant morphogenesis—the development of a plant’s form and structure—involves several overlapping developmental processes, including growth and cell differentiation. Precursor cells differentiate into specific cell types, which are organized into the tissues and organ systems that make up the functional plant.

Migration00:53

Migration

9.0K
Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.

Osmoregulation in Insects01:47

Osmoregulation in Insects

17.8K
Malpighian tubules are specialized structures found in the digestive systems of many arthropods, including most insects, that handle excretion and osmoregulation. The tubules are typically arranged in pairs and have a convoluted structure that increases their surface area.

Formation of Species01:31

Formation of Species

46.5K
Speciation describes the formation of one or more new species from one or sometimes multiple original species. The resulting species are discrete from the parent species, and barriers to reproduction will typically exist. There are two primary mechanisms, speciation with and without geographic isolation—allopatric and sympatric speciation, respectively.

Area of Science:

  • Ecology
  • Evolutionary Biology
  • Biogeography

Background:

  • Bioregionalisation categorises areas by biotic composition and evolutionary history.
  • A global bioregionalisation exists for angiosperms but is lacking for orchids.
  • Orchids are a globally relevant plant family.

Purpose of the Study:

  • To define the global bioregionalisation of orchids using phylogenetic beta diversity.
  • To analyse environmental drivers shaping orchid realms.
  • To assess the impact of sampling completeness and spatial resolution on bioregionalisation.

Main Methods:

  • Utilised 732,359 orchid distribution records and a phylogeny of 19,123 species.
  • Applied phylogenetic beta diversity at 200 × 200 km resolution.
  • Conducted analyses considering sampling completeness, metrics, and spatial resolutions.

Main Results:

  • Identified six global orchid realms: Australian, Andean-Patagonian, Neotropical, Afrotropical, Indo-Malaysian, and Holarctic.
  • Defined 10 bioregions and four main transition zones.
  • Found mean annual precipitation and temperature, along with their seasonality, significantly influence realm delimitation.

Conclusions:

  • Presents the first global bioregionalisation for orchids, detailing key environmental drivers.
  • Underscores the significance of bioregionalisation for understanding evolutionary patterns in taxonomic families.
  • Emphasizes accounting for sampling completeness and spatial resolution in bioregionalisation studies.
