Loss of Migratory Traditions Makes the Endangered Patagonian Huemul Deer a Year-Round Refugee in Its Summer Habitat (open access)

Loss of Migratory Traditions Makes the Endangered Patagonian Huemul Deer a Year-Round Refugee in Its Summer Habitat

This article analyzes the historical spatiotemporal behavior of the huemul (Hippocamelus bisulcus), an endangered deer endemic to Patagonia. Losing migratory traditions is a major threat, and may explain their presently prevalent skeletal diseases, reduced longevity, and lacking recolonizations for most remaining huemul subpopulations.

Childhood Asthma and Smoking: Moderating Effect of Preterm Status and Birth Weight (open access)

Childhood Asthma and Smoking: Moderating Effect of Preterm Status and Birth Weight

Article exploring the association between second-hand smoke exposure, asthma, and asthma severity in children ages 6-17 as well as the effect of birth weight and prematurity (BWP) on parental smoking and asthma.

Patch characteristics and domestic dogs differentially affect carnivore space use in fragmented landscapes in southern Chile (open access)

Patch characteristics and domestic dogs differentially affect carnivore space use in fragmented landscapes in southern Chile

This article's aim is to determine whether (a) the spatial use of domestic dogs increases with habitat destruction, and (b) domestic dogs and habitat destruction drive the spatial use of native carnivores in a heavily degraded agricultural landscape. Conclusions highlight that domestic dog occupancy was positively correlated with habitat loss and future conditions of increased fragmentation and habitat loss will likely increase the potential contact between domestic dogs and native carnivores.

Closed-form expressions for the magnetic fields of rectangular and circular finite-length solenoids and current loops (open access)

Closed-form expressions for the magnetic fields of rectangular and circular finite-length solenoids and current loops

This article discusses closed-form expressions for the magnetic fields produced by rectangular- and circular-shaped finite-length solenoids and current loops. The closed-form expression for the magnetic field of a rectangular-shaped finite-length solenoid is derived using the Biot–Savart law. Closed-form expressions for the magnetic fields of solenoids and current loops can be used to avoid approximations in analytical models and may reduce computation time in computer simulations.
