Post-mating parental behavior trajectories differ across four species of deer mice.

Among species, parental behaviors vary in their magnitude, onset relative to reproduction, and sexual dimorphism. In deer mice (genus Peromyscus), while most species are promiscuous with low paternal care, monogamy and biparental care have evolved at least twice under different ecological conditions. Here, in a common laboratory setting, we monitored parental behaviors of males and females of two promiscuous (eastern deer mouse P.

Application of a standard risk assessment scheme to a North Africa contaminated site (Sfax, Tunisia) -Tier 1.

Phosphorus is a critical element to agriculture, consequently global phosphate rock demand will remain rising to feed a growing world population. The beneficiation of phosphorous ore gives rise to several tons of a waste by-product [phosphogypsum (PG)] which valorisation is limited, within other reasons, by the risks posed to environment and human health. Although threatening, the accumulation in stacks is the only procedure so far practiced by several countries as a means to get rid of this industrial externality.

Irreproducible text-book "knowledge": The effects of color bands on zebra finch fitness.

Many fields of science-including behavioral ecology-currently experience a heated debate about the extent to which publication bias against null findings results in a misrepresentative scientific literature. Here, we show a case of an extreme mismatch between strong positive support for an effect in the literature and a failure to detect this effect across multiple attempts at replication. For decades, researchers working with birds have individually marked their study species with colored leg bands.

[Mediastinal neuroblastoma: Unusual localization with late revelation].

Neuroblastoma (NB) is an embryonal tumor of the sympathetic nervous system. It represents the most common malignant extracerebral solid tumor, and the first solid tumor in children aged less than one year. Neuroblastoma is rare in adults.

Spontaneous resolution of a tumor like pulmonary sarcoidosis.

We report a case of thoracic sarcoidosis in a 72-year-old female, snuff taker, who presented with multinodular pulmonary lesions on chest x-ray. Clinical and biological findings were poor. Thoracic imaging showed soft tissue density nodules with irregular borders.
