Environmentally Realistic Metal Mixture Concentration Impacts Early Development in Zebrafish Larvae

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT The dispersion of metals in the environment leads to the presence of metal mixtures in impacted ecosystems, but few studies have addressed their impact on early developmental processes in fish. Here, we investigated the effect of metal mixtures reported in the Doce River basin in Brazil, including Fe, Mn, and Cd, either singly or as a mixture ...

Experimental Evidence for Mobilization of Mercury From the Eggshell by the Developing Embryo in an Avian Model Organism

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Of the many pollutants wildlife is exposed to, mercury ranks among the most toxic. In birds, mercury does not only accumulate within generations, but also is transferred across generations via maternal offloading in eggs, with higher mercury concentrations found in shells of unhatched eggs.

Comparing the Effects of Microplastics From Conventional Cigarette Butts and Heated Tobacco Device: The Role of UV‐Induced Aging

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Despite the widespread presence of cigarette butts in the environment, the potential toxicological effects posed by microplastics (MPs) derived from them remain poorly understood. In this study, we compared the effects of MPs from conventional cigarette butts (cellulose acetate) and heated tobacco devices (cellulose acetate and polylactic acid

Factors influencing wintering turfgrass field use in Atlantic brant

open access: yesWildlife Biology, EarlyView.
Atlantic brant Branta bernicla hrota increasingly use turfgrass fields, such as baseball fields and golf courses, throughout their wintering range. Most studies have focused on their primary food source, submerged aquatic vegetation, while studies of other goose species worldwide have examined field use in different contexts, including agricultural ...

Nest-site selection, hatching success and hatchling over-winter success in painted turtles

open access: yes, 2003
Female painted turtles may increase their fitness either by increasing the success of their offspring within a single reproductive season, or by increasing the number of reproductive seasons in which they can participate. Painted turtle nest-sites can be

Influence of researcher presence towards nest attendance and breeding of barn owls Tyto javanica javanica

open access: yesWildlife Biology, EarlyView.
Human disturbance to nesting raptors can influence breeding success, especially during early breeding. This study examined the impact of researcher presence, a relatively low impact human disturbance, on eastern barn owls Tyto javanica javanica during monitoring of 57 nest‐boxes in oil palm plantations in Malaysia over a period of 30 months.

Evaluation of factors affecting greater prairie‐chicken nest and brood survival

open access: yesWildlife Biology, EarlyView.
Greater prairie‐chickens Tympanuchus cupido pinnatus in the Flint Hills ecoregion select recently burned grasslands for brooding and nest in areas that have been unburned for 1–3 years, suggesting the need for a mosaic of burn patches. However, it is unknown how patch area, configuration, and proximity to edges within such mosaics affect reproductive ...
