If species' ranges are randomly shuffled within a bounded geographical domain free of
environmental gradients, ranges overlap increasingly toward the center of the domain …

Numerous physical parameters that influence insect physiology vary substantially with
altitude, including temperature, air density, and oxygen partial pressure. Here, we review …

The greater latitudinal extents of occurrence of species towards higher latitudes has been
attributed to the broadening of physiological tolerances with latitude as a result of increases …

We compare different null models for species richness patterns in the Nepalese Himalayas,
the largest altitudinal gradient in the world. Species richness is estimated by interpolation of …

Aim To explore the variation in species richness along a subtropical elevation gradient, and
evaluate how climatic variables explain the richness of the different life forms such as trees …

Studying the distributions of plants and animals along environmental gradients can
illuminate the factors governing and maintaining species diversity. There are two general …

Aim The study explores fern species richness patterns along a central Himalayan
elevational gradient (100–4800 m asl) and evaluates factors influencing the spatial increase …

Umbrella species, species whose protection serves to protect many co‐occurring species,
have been proposed as a shortcut for conservation planning. Potential criteria for selection …

Altitudinal richness patterns were investigated along altitudinal gradients located in northern
Norway (two transects) and along a west–east gradient in southern Norway (five transects) …

Two aspects of patch geometry—area and isolation—currently dominate the field of
metapopulation dynamics. Under this area‐and‐isolation paradigm, models commonly …
