Further, our rationale for listing each of these five species as threatened species, versus endangered species, is discussed under Determination, below. (2) We updated the section titled "Historical and Ongoing Human Impacts" under The Mariana Islands, below, to include recent changes in proposed ...
This tension persists today, albeit in a more contemporary form: public access demand versus ecosystem conservation. The focus of this study is the influence of this tension on local-level management of federally threatened and endangered species. We surveyed managers of 43 locations of ecological ...
Industrial-scale harvest of species at risk of extinction is controversial and usually highly regulated on land and for charismatic marine animals (e.g. whales). In contrast, threatened marine fish species can be legally caught in industrial fisheries. T
The changes in δ13C and δ15N of sheltered cats versus time are shown in Fig. S1. The estimated asymptotes of the regression model (TEF) of δ13C and δ15N were 2.3 ± 0.3 and 2.8 ± 0.1, respectively. The stable isotope analysis in R (SIAR) indicated that artificial re...
To improve the relationship between recovery spending on threatened and endangered birds and their priority rank, significant changes need to be made within the Private sector (less litigation and special-interest lobbying), US, Congress (increased budget and reduced earmarking), and the U.S. Fish...
always helpful. The amygdala can sometimes overreact to potential risks, at which point it triggers anxiety. Anxiety can often overtake the logical side of our brain, causing more harm than good, so it's important to recognize when gut feelings are indicative of actual intuition versus paranoia...

We determined the relative contributions of drift versus gene flow across the distribution area, using the likelihood approach implemented in the program 2MOD119. Two models were compared: the drift model relates to populations that are subject to drift alone, with no influence from gene flow, whi...
First, how often do federal agencies and NMFS disagree about the effects of their actions on threatened and endangered species? This knowledge is important to assess whether self-consultation would maintain or reduce protections for listed species. Second, what are the general patterns of consultation...
