Comparative evaluation of funnel, box, and camera traps for reptile and amphibian inventory

Wildlife Society Bulletin, EarlyView.
We used data from 5 herpetological inventories conducted in Florida to evaluate the relative efficacy of funnel, box, and motion‐triggered camera traps for detecting reptile and amphibian species along drift‐fence arrays. Our results suggest that a hybrid array design (funnel traps + central camera trap) is best suited for general herpetofaunal ...

SCOUR AT ELLIPTICAL GUIDE BANKS UNDER STRATIFIED BED CONDITIONS: EQUILIBRIUM STAGE

The scour development in time and the equilibrium stage of scour near abutments and guide banks with a uniform layer and stratified bed conditions have been studied.

Temporal community change in stream ecosystems varies by assemblage across US climates

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecosystem properties are temporally dynamic. Temporal variability has been shown to decrease with increasing levels of biological organization (i.e. from population to community and ecosystem levels).

Herbivore and mesocarnivore carcasses trigger divergent short‐term changes in soil properties

Journal of Animal Ecology, EarlyView.
Scavengers reshape nutrient cycles in soils under carrion. Compared to herbivore carcasses, smaller but longer‐lasting carnivore remains boost nutrient levels and microbial activity in dry soils. Abstract Animal corpses act as pulses of organic matter (OM) and serve a key zoogeochemical role by providing localized nutrient inputs to soils and thereby ...

Invasive goldfish trigger a regime shift in experimental lake ecosystems of varying trophic state

Journal of Animal Ecology, EarlyView.
The pet trade distributes exotic animals around the globe that enrich human lives. However, some pets become pests when released into the wild. This study provides experimental evidence that goldfish will negatively affect native freshwater organisms and ecosystems.

Scour Development and Bridge Abutment Safety during the Floods

Bridge crossings on plain rivers were modelled and scour development at the abutments and guide banks were studied. Tests were carried out in flumes 3.5 m wide and 21 m long in clear water conditions for FrR = Frf.

Scour Effects on Coastal Defense Structures. Examples from the Portuguese West Coast

, 2006
Different types of coastal defense structures are used to protect shoreline against coastal erosion and flooding. Many of these structures were built on sand or soil material that can be easily removed or eroded by the action of waves, currents or ...

A reappraisal of the Middle to Later Stone Age prehistory of Morocco Réévaluer la préhistoire du Maroc, du Middle Stone Age au Later Stone Age

Journal of the Royal Anthropological Institute, EarlyView.
Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.

Cuttings, Combings, Fettlings and Flock: Gender and Australian Wool ‘Waste’, 1900–1950

Gender &History, EarlyView.
ABSTRACT As Australia's wool industry produced vast amounts of fine fleece from the nineteenth century, the wool processing and clothes manufacturing industries generated waste – products like cuttings, combings, fettlings and flock. Salvaged and then sold to waste merchants, these and other materials had a second life.

Effect of the River Bed Stratification on Scour at Guide Banks

The failure of guide banks because of scour at stratified bed conditions leads to the flow redistribution and an unpredicted scour at the alignment of the bridge crossing; as a result, this can be the reason for failure of piers and/or abutments.
