Mammalian Niche Conservation through Deep Time
Climate change alters species distributions, causing plants and animals to move north or to higher elevations with current warming. Bioclimatic models predict species distributions based on extant realized niches and assume niche conservation. Here, we evaluate if proxies for niches (i.e., range areas) are conserved at the family level through deep time, from the Eocene to the Pleistocene. We a...
متن کاملModelling the climatic niche of turtles: a deep-time perspective
Ectotherms have close physiological ties with the thermal environment; consequently, the impact of future climate change on their biogeographic distributions is of major interest. Here, we use the modern and deep-time fossil record of testudines (turtles, tortoises, and terrapins) to provide the first test of climate on the niche limits of both extant and extinct (Late Cretaceous, Maastrichtian...
متن کاملApplication of niche modelling to analyse biogeographic patterns in Palaeozoic brachiopods: evaluating niche stability in deep time
THE GEOGRAPHIC area inhabited by a species is constrained by its ecological niche, the multidimensional set of environmental variables that determines where members of a species can survive and maintain viable populations (Grinnell 1917). Individual organisms have the physiological capacity to inhabit any geographic location characterised by physical parameters within the constraints of the spe...
متن کاملThe Niche
The concept of niche (setting, context, habitat, environment) has been little studied by ontologists, in spite of its wide application in a variety of disciplines from evolutionary biology to economics. What follows is a first formal theory of this concept, a theory of the relations between objects and their niches. The theory builds upon existing work on mereology, topology, and the theory of ...
متن کاملLearning the ecological niche.
A cornerstone of ecological theory is the ecological niche. Yet little is known about how individuals come to adopt it: whether it is innate or learned. Here, we report a cross-fostering experiment in the wild where we transferred eggs of blue tits, Cyanistes caeruleus, to nests of great tits, Parus major, and vice versa, to quantify the consequences of being reared in a different social contex...
