Closer to the Heart: Cardiac Muscle Aerobic Capacity Correlates With Intraspecific Variation in Sprint Performance Rather Than Androgen Levels in the Neotropical Lizard Tropidurus catalanensis

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
In male lizards Tropidurus catalanensis, sprint locomotor performance correlates with cardiac aerobic capacity. ABSTRACT Assessments of the interplay between physiology and whole‐organism performance are fundamental to understand how individuals function in different ecological contexts.

Impact of dredging on the volute Cymbiolacca pulchra and its environment at Heron Island, Great Barrier Reef, Australia [PDF]

open access: yes, 1992
The impact of dredging operations on the volute Gastropod (Cymbiolacca pulchra) population of a coral reef atoll (Heron Island, Great Barrier Reef, Australia) was investigated using data from annual surveys of the population and its environment ...

Boron availability and fertilizer response of maize in soils from sub‐Saharan Africa

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
Abstract Background and aims Low boron (B) availability is associated with strongly weathered, coarse‐textured, and low organic matter soils, widespread in sub‐Saharan Africa (SSA). It is unknown to what extent B fertilization can increase maize yields in SSA.

Landscape suitability and range expansion estimates for the North American Interior Population of trumpeter swans

open access: yesThe Journal of Wildlife Management, EarlyView.
We incorporated landscape suitability into a trumpeter swan range expansion model. We estimated a 4.4% (95% CI: 2.0–6.9%) annual range expansion rate from 2023 to 2033, with expansion occurring in the Prairie Pothole Region of the Dakotas and the Boreal Shield and James Bay Lowlands of Canada. Abstract The Interior Population of trumpeter swans (Cygnus

Valorization of saline dredged sludge by low-carbon geopolymer production: Salt content impact, mechanisms, and carbon emissions

open access: yesResults in Engineering
This study demonstrates a green and low-carbon approach for valorizing saline dredged sludge (DS) by producing geopolymers from DS combined with fly ash (FA) and ground granulated blast furnace slag (GGBS), activated by an alkaline activator ...

Accounting for environmental uncertainty in the management of dredging impacts using probabilistic dose-response relationships and thresholds

open access: yes, 2018
Summary 1.Dredging and related activities are common across nearshore marine environments, potentially threatening nearby ecosystems. Regulatory frameworks are essential for minimising environmental impacts, yet rely heavily on a sound understanding of ...

Detecting sedimentation impacts to coral reefs resulting from dredging the Port of Miami, Florida USA

open access: yesPeerJ, 2016
The federal channel at Port of Miami, Florida, USA, was dredged between late 2013 and early 2015 to widen and deepen the channel. Due to the limited spatial extent of impact-assessment monitoring associated with the project, the extent of the dredging ...

Seagrasses under stress: Independent negative effects of elevated temperature and light reduction at multiple levels of organization

open access: yesLimnology and Oceanography, EarlyView.
Abstract Seagrasses are important foundation species, which support coastal biodiversity and provide socioeconomic benefits. However, seagrasses are threatened by anthropogenic changes, including the elevated temperature associated with marine heatwaves (MHWs) and light limitation from eutrophication or increased sedimentation.

Experimental and numerical flow field study of submerged translating impinging inclined water jets

open access: yesFlow
This study investigates the influence of multiple jet parameters on the flow field of translating impinging inclined water jets. We conducted full-scale stereoscopic particle image velocimetry and pressure measurements and three-dimensional computational

Significant Human Modification of the Lower Arkansas River Sediment Budget

open access: yesGeophysical Research Letters, 2022
Anthropogenic stressors on large rivers have significantly modified riverine sediment transport. However, the impacts of dredging and sand and gravel (S&G) mining are poorly monitored.
