The Gravitational Red-Shift [PDF]
arXiv, 2004 Attention is drawn to the fact that the well-known expression for the red-shift of spectral lines due to a gravitational field may be derived with no recourse to the theory of general relativity. This raises grave doubts over the inclusion of the measurement of this gravitational red-shift in the list of crucial tests of the theory of general ...

Applying Bergmann's Rule to Species Conservation Planning 贝格曼法则在物种保护规划中的应用
Integrative Conservation, EarlyView.Although Bergman's rule has extensively been studied, its implications in species conservation have not been clear, especially in the context of climate change (global warming). Here, we discuss the potential applications of the “rule” based on IUCN's (2022) Red List and suggest species' body size to be an important ecological indicator in future long ...

Assessing release strategies for reintroductions of endangered Wyoming toads
Wildlife Society Bulletin, Volume 46, Issue 5, December 2022., 2022 We performed reintroductions of captive‐bred Wyoming toads (Anaxyrus baxteri) (photo B.) to test the effects of soft‐ and hard‐release methods through implementation of a delayed‐release. After release, the toads were tracked using a harmonic tracking system in Wyoming, USA. The soft‐released toads were held in an outdoor enclosure for 14 days prior to

On the Interpretation of Spectral Red-Shift in Astrophysics: A Survey of Red-Shift Mechanisms - II [PDF]
arXiv, 2018 This paper gives a compilation of physical mechanisms which have been proposed to explain the spectral red-shift of distant astronomical objects. Over sixty selected mechanisms are listed for the purpose of quantitative comparisons. Some of these mechanisms may not completely account for all astrophysical observations but are relevant to particular ...

FeI lines in 0.91-1.33 ${\rm μ}$m spectra of red giants for measuring the microturbulence and metallicities [PDF]
, 2019 For a detailed analysis of stellar chemical abundances, high-resolution spectra in the optical have mainly been used, while the development of near-infrared (NIR) spectrograph has opened new wavelength windows. Red giants have a large number of resolved absorption lines in both the optical and NIR wavelengths, but the characteristics of the lines in ...

Establishing and monitoring island breeding colonies to conserve an imperiled lagomorph
The Journal of Wildlife Management, EarlyView.Islands have a long history in species conservation and are often employed because they have fewer predators and competitors than mainland sites. Recently, 2 islands have been established as breeding colonies to support New England cottontail conservation. In the right circumstances, islands could be used to support the conservation of other lagomorphs
