How these connect

Southern Serengeti Short-Grass Plains and what it relates to. Every line is an evidence-backed relation, and the arrangement is fixed — this address draws this picture, today and next year.

  1. Volcanic Ash Soils of the Southern Plains · fertilises · Southern Serengeti Short-Grass Plains

    Ash from the Crater Highlands volcanoes forms the shallow phosphorus- and calcium-rich soils underlying the short-grass plains

  2. Southern Serengeti Short-Grass Plains · limits · Blue Wildebeest (Connochaetes taurinus)

    Dry-season food supply, not predation, regulated the population across the post-rinderpest irruption and the 1993–94 drought die-off of roughly 250,000 animals

  3. Synchronised Wildebeest Calving · depends_on · Volcanic Ash Soils of the Southern Plains

    The plains chosen for calving are the ecosystem's driest but their ash-derived soils yield grass comparatively rich in phosphorus and calcium, the minerals a lactating female needs

  4. Blue Wildebeest (Connochaetes taurinus) · calves_on · Southern Serengeti Short-Grass Plains

    The herds concentrate on the short-grass plains between roughly December and April and the large majority of births occur there

  5. Synchronised Wildebeest Calving · occurs_on · Southern Serengeti Short-Grass Plains

    The three-week birth pulse takes place on the short-grass plains and their westward continuation into the Ngorongoro Conservation Area

  6. Southern Serengeti Short-Grass Plains · continuous_with · Ngorongoro Conservation Area — Western Plains

    The plains cross the Serengeti National Park boundary and continue into the western Ngorongoro Conservation Area around Ndutu and Salei
