metadata.value: This paper seeks to shed light on the primary causes of the latitudinal cline in
  species diversity, the asymmetry in species richness between the northern and
  southern hemispheres, and various patterns of species richness along mountain
  and continental slopes, which are at present of central interest in ecology.
  To that end, we restate, further develop and unify Janzen’s ideas about
  the higher fidelity of tropical organisms to their habitats; the notions of Sanders
  on temporal and spatial variations of environment and their impact on the
  breadth of species adaptations; the hypothesis of latitude-niche breadth and
  niche overlap; the theories of climatic stability, competitive exclusion and competitive
  divergence with the incorporation of some elements of the gradient
  model of diversification. We argue that during adaptation to a wide range of
  the same environmental factors in time, the high latitude species also become
  adapted to a wide range of those factors in space. As a result, they form not
  only very wide, but also widely overlapping ecological niches. This eventually
  leads to the competitive extinction of many species and a general impoverishment
  of biota. In contrast, relatively stable environments allow species to move
  more and more towards specialization with a simultaneous narrowing of their
  ecological niches that in turn leads to a reduction of niche overlap and greater
  species packing in communities. In tropical mountains and on the continental
  slope, where the environment is stable enough, the degree of its differentiation
  depends mainly on the steepness of slope. And since the steepest slopes tend
  to be located at intermediate elevations and intermediate bathyal depths, it is
  there that there are conditions for the highest specialization. These ideas can
  provide a framework for new approaches to biodiversity conservation of different
  regions.
