Measurement of the A-Value of the Intersystem Transition in Al II at 2670 Å: Å Progress Report [PDF]
Ratios of intensities of spectral lines produced in the radiative decay of collisionally-excited levels of atomic ions are versatile indicators of electron density in astrophysical plasmas when one of the lines involves a metastable level (see the review by Feldman 1981 and references therein). Radiative transition probabilities (A-values) and electron

A review to the methods of personality measurements in wild animals 野生动物个性测量方法的综述
One of the challenges in animal personality study is finding a suitable method to measure personality. Here, we outlined three methods (traits rating, behavioral coding, and experimentation) used in animal personality measurement. We found that traits rating was commonly used to test large‐sized animals (e.g., primates), behavioral coding was conducted

Abstract Inner phenomena, such as personal motivations for pursuing sustainability, may be critical levers for improving conservation outcomes. Most conservation research and policies, however, focus on external phenomena (e.g., ecological change or economic processes). We explored the factors shaping 9 conservation attitudes toward forest and wildlife

Association of reproductive traits with captive‐ versus wild‐sourced birds in trade
Abstract The wildlife trade is a billion‐dollar global business, involving millions of people, thousands of species, and hundreds of millions of individual organisms. Unravelling whether trade targets reproductively distinct species and whether this preference varies between captive‐ and wild‐sourced species is a crucial question.

Abstract Managed breeding programs are an important tool in marsupial conservation efforts but may be costly and have adverse genetic effects in unavoidably small captive colonies. Biobanking and assisted reproductive technologies (ARTs) could help overcome these challenges, but further demonstration of their potential is required to improve uptake. We
