Niche breadth predicts geographical range size: a general ecological pattern.
The range of resources that a species uses (i.e. its niche breadth) might determine the geographical area it can occupy, but consensus on whether a niche breadth-range size relationship generally exists among species has been slow to emerge. The validity of this hypothesis is a key question in ecology in that it proposes a mechanism for commonness and rarity, and if true, may help predict speci...
متن کاملExplanations for bird species range size: ecological correlates and phylogenetic effects in the Canary Islands
Aim To explore the determinants of island occupancy of 48 terrestrial bird species in an oceanic archipelago, accounting for ecological components while controlling for phylogenetic effects. Location The seven main islands of the Canary archipelago. Methods We obtained field data on density, habitat breadth and landscape distribution in Tenerife, Fuerteventura and La Palma, trying to sample the...
متن کاملNegative range size–abundance relationships in Indo-Pacific bird communities
tropical areas and those in temperate zones. Hypotheses to explain positive range size–abundance relationships have focused on the ability of generalist species to appropriate resources, which allows them to simultaneously expand their ranges and dominate local communities (Brown 1984). The combination of geographic isolation with the high environmental stability of the tropics, however, may cr...
متن کاملSize, shape, and the thermal niche of endotherms.
A key challenge in ecology is to define species' niches on the basis of functional traits. Size and shape are important determinants of a species' niche but their causal role is often difficult to interpret. For endotherms, size and shape define the thermal niche through their interaction with core temperature, insulation, and environmental conditions, determining the thermoneutral zone (TNZ) w...
متن کاملChanges in dispersal during species' range expansions.
Explanations for rapid species' range expansions have typically been purely ecological, with little attention given to evolutionary processes. We tested predictions for the evolution of dispersal during range expansion using four species of wing-dimorphic bush cricket (Conocephalus discolor, Conocephalus dorsalis, Metrioptera roeselii, and Metrioptera brachyptera). We observed distinct changes ...
