Abstract. Ecosystem engineering – the physical modification of habitats by organisms – has been proposed as an important mechanism for maintaining high species richness at the landscape scale by increasing habitat heterogeneity. Dams built by beaver (Castor canadensis) dramatically alter riparian landscapes throughout much of North America. In the central Adirondacks, New York, USA, ecosystem engineering by beaver leads to the formation of extensive wetland habitat capable of supporting… 
Spatiotemporal changes in biodiversity by ecosystem engineers: how beavers structure the richness of large mammals
TLDR
This work compared the richness and composition of boreal mammals using camera traps between habitats with and without history of occurrence by beavers within a protected area, where trapping, hunting, and forest exploitation are prohibited.
Rewilding wetlands: beaver as agents of within-habitat heterogeneity and the responses of contrasting biota
TLDR
Independent of habitat creation beaver are significant agents of within-habitat heterogeneity that differentiates BP from other standing water habitat; as an integral component of the rewilding of wetlands re-establishing beaver should benefit aquatic biodiversity across multiple scales.
LOCAL VS. LANDSCAPE CONTROLS ON PLANT SPECIES RICHNESS IN BEAVER MEADOWS
TLDR
The results indicate that species richness in beaver meadows is strongly controlled by local factors, but that the population dynamics of beaver could also potentially affect species richness by altering the age distribution of meadows across the landscape.
Complementary influences of co-occurring physical ecosystem engineers on species richness: insights from a Patagonian rocky shore
TLDR
It is postulated that complementary engineering effects on landscape-level species richness will occur when the engineered patches structurally differ from each other and, thus, vary in their relative ability to modulate two or more abiotic conditions and/or resources that prevent species establishment in the unengineered state.
Ecosystem engineering affects ecosystem functioning in high-Andean landscapes
TLDR
It is suggested that the application of the conceptual framework proposed herein to other ecosystems would help to advance the understanding of the forces driving ecosystem functioning.
Ecosystem engineers maintain a rare species of butterfly and increase plant diversity
TLDR
It is found that beavers created wetland habitats that supported plant species not found elsewhere in riparian zones and increased plant species diversity across the landscape by creating a novel combination of patch types.
Elephants as agents of habitat creation for small vertebrates at the patch scale.
TLDR
It is shown that, by damaging trees and increasing their structural complexity, browsing elephants create refuges used by a common arboreal lizard, suggesting that anthropogenic changes in large-mammal densities will have important cascading consequences for ecological communities.
The important role of ecological engineers in providing ecosystem services at landscape level
One of the central questions in ecology is how biological diversity relates to ecological functions (Peterson, Allen & Holling, 1998). This question has become increasingly relevant as anthropogenic
Predictability of ecosystem engineering effects on species richness across environmental variability and spatial scales

Impact of pocket gopher disturbance on plant species diversity in a shortgrass prairie community
TLDR
It is found that 10 of the most common herbaceous perennial dicots benefit from pocket gopher disturbance, and a greater proportion of seedlings are found in the open space created by pocket gophers disturbance than would be expected based on the availability of disturbed habitat.
Ecology of a Grazing Ecosystem: The Serengeti
TLDR
Great species diversity was associated with greater biomass stability through the seasons, greater resistance to grazing by a single species of ungulate in both the wet and dry seasons, and greater resilience after grazing, and specific properties of trophic web members were identified that produced greater functional stability in more diverse communities.
Alteration of North American streams by beaver
TLDR
Although once more prevalent than they are today, beaver-induced alterations to drainage networks are not localized or unusual and must be interpreted over broad spatial and temporal scales as beaver population dynamics shift in response to disturbance, food supply, disease, and predation.
Disturbance in Marine Intertidal Boulder Fields: The Nonequilibrium Maintenance of Species Diversity
TLDR
The effects of disturbance on local species diversity were investigated in an algal- dominated intertidal boulder field in southern California and suggest that disturbances which open space are necessary for the maintenance of diversity in most commu- nities of sessile organisms.
Small mammals, ectomycorrhizae, and conifer succession in beaver meadows
Beaver (Castor canadensis) build dams and create ponds on streams within forested areas. Upon abandonment, ponds often drain and the subsequent meadows persist for decades as graminoid patches that
The effects of beaver in riverbank forest succession
TLDR
A major reduction in density is predicted for future populations of ash, hickory, and hackberry in areas of beaver activity, with a concomitant increase in the density of basswood and elm and possibly silver maple and prickly ash.

TLDR
The results support the predictions that intermediate levels of disturbance and small-scale environmental heterogeneity contribute to supporting high species diversity.
