Plant and soil biodiversity reveals past and potential future states of naturally regenerating and planted native forests

Restoration Ecology, EarlyView.
Abstract Introduction Forest restoration can be achieved by promoting natural regeneration or planting tree seedlings, but the relative benefits of these widely used approaches are questioned. Soil communities may influence restoration outcomes but are usually ignored by monitoring schemes.

Beaver dam analogues increase amphibian breeding occupancy and bat activity

Restoration Ecology, EarlyView.
Abstract Introduction Beavers are ecosystem engineers that can create ponds, increase stream complexity, and enhance biodiversity. To mimic these and other effects, restoration practitioners increasingly install beaver dam analogues (BDAs) in degraded streams.

Microbial influence on the formation and subsequent changes of vertebrate tracks: field experiments on present‐day coastal sediments

Sedimentology, EarlyView.
ABSTRACT The presence of microbial mats is often invoked to explain the good preservation of vertebrate tracks, because they can cover and biostabilize such structures. However, microbial influence on the sediment properties when the track is made and on the track characteristics has not been so thoroughly analysed.

Microbial mats in dinosaur ichnocoenoses

Sedimentology, EarlyView.
ABSTRACT Until now, the significance of microbial mats in preservation of dinosaur tracks and in reconstructing the palaeoenvironment in which dinosaurs roamed was rarely studied. Dinosaur tracks are commonly found close to ancient aquatic bodies where moist sediment had once allowed footstep registration.

Local scour around a vertical wall

, 1999
This study investigates local scour at a vertical wall induced by ship propellers. The primary objectives are to study the scour process and to identify the factors governing the formation of the scour hole. This study focuses on the final development and the equilibrium state of the scour hole and its governing factors. Master of Engineering (CSE)
