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

open access: yesWildlife 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 ...

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

open access: yesFunctional 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).

Estimation of Local Scour Dimension below Siphon Spillway with the Ski-jump Bucket Energy Dissipater Using the Group Method of Data Handling (GMDH)

open access: yesعلوم آب و خاک, 2018
The investigation of local scour below hydraulic structures is so complex that makes it difficult to establish a general model to provide an accurate estimation for the local scour dimension.

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

open access: yesJournal 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

open access: yesJournal 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.

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

open access: yesJournal 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

open access: yesGender &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.

ON THE BRIGHTER SIDE OF THE NIGHT: Discovering Community and Care in Night Shift Work

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract Within the burgeoning attention being paid to the night‐time economy (NTE) in and by cities, the demands and impacts of night work have gathered increasingly scholarly attention. Research has centred on the darker side of these, pointing to workers' precarity and vulnerability. What if we attend also to a ‘brighter side’ of the night and night

Ozone‐driven degradation of sex pheromone in Plutella xylostella: Implications for reproductive communication and mating success

open access: yesInsect Science, EarlyView.
In this study, we examined whether realistic ozone concentrations can interfere with sexual communication in the insect pest Plutella xylostella, the diamondback moth. Ozone exposure caused a degradation of pheromone components, leading to significant changes in blend composition and component ratios.
