Linking regional and global functional trait data: insights from mammal communities in a fragmented Atlantic Forest landscape

open access: yesOikos, EarlyView.
Accurate functional trait data are essential for understanding ecosystem services and processes in fragmented landscapes. We evaluated whether the global EltonTraits 1.0 database adequately represents the functional structure of mammal communities in forest fragments and restoration sites in a highly fragmented Atlantic Forest landscape.

Nonthermal Mg I Emission At 12 Micron From Procyon [PDF]

open access: yes, 2004
We report on stellar Mg i emission at 12 mu m from alpha CMi (Procyon), a star slightly hotter than the Sun. Solar Mg i emission is well known, and its formation was successfully explained in detail by Carlsson et al.

Unraveling the impact of dog‐friendly spaces on urban–wildland pumas and other wildlife

open access: yesWildlife Biology, EarlyView.
As the most widespread large carnivore on the planet, domestic dogs Canis lupus familiaris can pose a major threat to wildlife, even within protected areas (PAs). Growing human presence in PAs, coupled with increasing pet dog ownership underscores the urgency to understand the influence of dogs on wildlife activity and health.

Can Sodium Abundances of A-Type Stars Be Reliably Determined from Na I 5890/5896 Lines?

open access: yes, 2009
An extensive non-LTE abundance analysis based on Na I 5890/5896 doublet lines was carried out for a large unbiased sample of ~120 A-type main-sequence stars (including 23 Hyades stars) covering a wide v_e sin i range of ~10--300 km/s, with an aim to ...

AME - Asteroseismology Made Easy. Estimating stellar properties by use of scaled models [PDF]

open access: yes, 2014
We present a new method to obtain stellar properties for stars exhibiting solar-like oscillations in an easy, fast, and transparent way. The method, called Asteroseismology Made Easy (AME), can determine stellar masses, mean-densities, radii, and surface

Differences in mammal community response to highway construction across different levels of human land use

open access: yesWildlife Biology, EarlyView.
Worldwide, transportation agencies have been involved in road mitigation efforts to reduce road mortality and promote connectivity of endangered species. Baseline data on how mammals respond to highway construction, however, are rarely collected in road mitigation and monitoring studies, including in the USA.

Citizen science project on urban canids provides different results from camera traps but generates interest and revenue

open access: yesWildlife Biology, EarlyView.
As urbanization increases, wildlife increasingly encounters people. Coyotes Canis latrans and red foxes Vulpes vulpes are two canid species that have readily adapted to urban environments. Citizen science has emerged as a low‐cost method of collecting data on urban‐adapted species that can benefit management agencies but may provide different results ...

The photospheric solar oxygen project: II. Non-concordance of the oxygen abundance derived from two forbidden lines

open access: yes, 2013
In the Sun, the two forbidden [OI] lines at 630 and 636 nm were previously found to provide discrepant oxygen abundances. aims: We investigate whether this discrepancy is peculiar to the Sun or whether it is also observed in other stars.

Coronal versus photospheric abundances of stars with different activity levels [PDF]

open access: yes, 2003
We report a detailed analysis of the coronal abundance of 4 stars with varying levels of activity and with accurately known photospheric abundances.

Wildlife temporal behaviors in response to human activity changes during and following COVID‐19 park closures

open access: yesWildlife Biology, EarlyView.
With urbanization reducing the amount of available wildlife habitat, and outdoor recreation increasing the human activity within wildlife habitats, it is important to understand the effects of human activity on animal behavior. This study examined how the reduction in human presence in urban parks in Gainesville, Florida, affected the temporal ...
