Warming enhances primary production and respiration and changes plankton community structure in an estuarine upwelling system

Limnology and Oceanography, EarlyView.
Abstract Marine heatwaves are expected to become more frequent and intense due to global climate change, potentially impacting plankton communities. In the present study, the effects of a simulated short‐term warming event on the structure and functioning of coastal plankton communities were investigated during a mesocosm experiment conducted with ...

Incorporation of diazotrophically fixed nitrogen by juvenile fish in a coastal sea

Limnology and Oceanography, EarlyView.
Abstract Nitrogen‐fixing cyanobacterial blooms worldwide have been shown to support production in primary consumers such as zooplankton and benthic invertebrates, but there have been few estimates of how much of the cyanobacterial nitrogen ends up in secondary consumers, such as fish.

A large, infrequent ecosystem subsidy (cicada carcasses) and warming additively accelerate development and increase growth of larval amphibians

Limnology and Oceanography, EarlyView.
Abstract Many ecosystems receive resource subsidies that affect productivity and food webs. Ecosystem subsidies vary in quantity, quality, and timing, and effects are often mediated by environmental factors, including temperature. Deposition of periodical cicada carcasses into ponds represents a large, high‐quality, infrequent subsidy.

Temporal Variability of Atmospheric Total Gaseous Mercury in Windsor, ON, Canada

Atmosphere, 2014
Atmospheric Total Gaseous Mercury (TGM) concentrations were monitored in Windsor, Ontario, Canada, during 2007 to 2011, to investigate the temporal variability of TGM. Over five years, the average concentration was 2.0 ± 1.3 ng/m3.

Phytoplankton iron limitation in the Atlantic Southern Ocean driven by seasonal mixed‐layer dynamics

Limnology and Oceanography Letters, EarlyView.
Abstract Phytoplankton blooms in the Southern Ocean (SO) are seasonally limited by light and micronutrients. As such, regional variations in iron supply from mixed‐layer winter entrainment are expected to impact the extent of seasonal iron limitation. Here, we determined seasonal iron limitation in the Atlantic SO by conducting iron addition incubation

Numerical Modeling of the Recession and Closure of Planar Hydraulic Fractures: Contact‐Based Versus Asymptotic‐Informed Schemes

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT We compare two algorithms to simulate the propagation, arrest, recession, and closure of a planar hydraulic fracture, focusing on their ability to capture the physical processes governing fracture recession and closure. The first algorithm is based on a fixed grid with contact detection during recession, while the second is based on a moving ...

The impact of gigafire on vegetation structure, terrestrial vertebrate abundance and diel activity

Oikos, EarlyView.
Fire regimes are shifting around the world due to climate and land‐use change, resulting in an increased frequency of large and severe wildfires. However, the impact of extreme wildfire events on animal species remains poorly understood. Particularly lacking is an understanding of how fire affects animal behaviour.

Functional and phylogenetic beta diversity response of nocturnal moth assemblages to land‐use intensity in grasslands and forests

Oikos, EarlyView.
Land‐use intensification is filtering for species, able to cope with anthropogenic landscapes. This was assumed to result in functionally and phylogenetically homogenous communities, but a recent meta‐analysis could not confirm a consistent homogenization response to human pressure and raises open questions.

Saplings of significance: Nurturing cultural value of new tree plantings through participatory opportunities

People and Nature, EarlyView.
Abstract Tree‐planting initiatives are a crucial part of international sustainability and climate action efforts. Yet, many of these initiatives fail to achieve their long‐term sustainability and climate goals. The role of community value is an often‐overlooked factor in promoting the success of new tree plantings.
