Rewilded mammal assemblages reveal the missing ecological functions of granivores

Global patterns in the phylogenetic structure of island mammal assemblages.

Assemblage-level phylogenies carry the signature of ecological and evolutionary processes, which may provide useful information on modes of assemblage formation. We present a global-scale analysis of the emergent phylogenetic properties of mammal assemblages on islands, in which we compared the structure of 595 island assemblages with null models constructed under four alternative definitions o...

Community inertia of Quaternary small mammal assemblages in North America.

One of the longest running debates in ecology is whether chance or determinism structures biotic communities, and this question is often studied by looking for the presence or absence of community inertia (lack of change) over time or space. Results have been equivocal. We adopted three tactics for a fresh approach: (i) allowing the answer to vary with the geographic, temporal, and taxonomic sc...

Genotype-by-Environment Interactions Emerge from Simple Assemblages of Mathematical Functions in Ecological Models

Elk herbivory alters small mammal assemblages in high-elevation drainages.

Heavy herbivory by ungulates can substantially alter habitat, but the indirect consequences of habitat modification for animal assemblages that rely on that habitat are not well studied. This is a particularly important topic given that climate change can alter plant-herbivore interactions. We explored short-term responses of small mammal communities to recent exclusion of Rocky Mountain elk (C...

The missing Wendland functions

and leave out the integer order spaces in even dimensions. We derive the missing Wendland functions working for half–integer k and even dimensions, reproducing integer–order Sobolev spaces in even dimensions, but they turn out to have two additional non–polynomial terms: a logarithm and a square root. To give these functions a solid mathematical foundation, a generalized version of the “dimensi...
