Assigning trend‐based conservation status despite high uncertainty
Abstract Estimates of temporal trends in species’ occupancy are essential for conservation policy and planning, but limitations to the data and models often result in very high trend uncertainty. A critical source of uncertainty that degrades scientific credibility is that caused by disagreement among studies or models.

Understanding the structure of the Post‐2020 Global Biodiversity Framework. Abstract December 2022 finally saw the historic agreement of the Kunming‐Montreal Global Biodiversity Framework (KM‐GBF), a landmark framework that sets to halt and reverse global biodiversity loss by remedying the multifaceted drivers behind biodiversity declines around the ...

Climate suitability as a predictor of conservation translocation failure
Abstract The continuing decline and loss of biodiversity has caused an increase in the use of interventionist conservation tools, such as translocation. However, many translocation attempts fail to establish viable populations, with poor release site selection often flagged as an inhibitor of success.

ABSTRACT Internal oxidation has been identified as an effective method for enhancing the strength of AgMg alloys. However, the concurrent occurrence of embrittlement remains inadequately understood, thus limiting their broader application. This study investigates the oxidation behavior of AgMg alloys with Mg concentrations ranging from 1 at% to 7 at ...

Oxidation Performance of NiCoCrAlYTa + 7YSZ Coatings With Ta Addition at Different Temperatures
ABSTRACT This study investigates the morphology and oxidation behavior of thermally grown oxides (TGO) formed at the interface of NiCoCrAlYTa + 7YSZ (7 wt% Y2O3‐stabilized zirconia) coatings deposited by air plasma spray (APS) in air environments at 1050°C, 1100°C, and 1150°C. The enrichment of Ta‐rich oxides beneath the TGO, along with the segregation

Opportunities, research gaps, and risks in allogenic ecosystem engineer mimicry
Abstract In an age of anthropogenically driven species loss and increasingly novel ecosystems, ecosystem engineer restoration is a process‐based approach to supporting ecosystem function. Many ecosystem engineers have low or declining population sizes.

Abstract Posttraumatic stress disorder (PTSD) commonly co‐occurs with pain and has been implicated in the maintenance of chronic pain. However, limited research has examined whether intervening for PTSD can hinder or optimize treatment outcomes for co‐occurring pain and PTSD.

为了提高杆塔接地装置的降阻效率,通过电磁分析软件CDEGS建模,研究了降阻材料敷设厚度和敷设位置对接地电阻的影响。结果表明:随着降阻材料敷设厚度的增加,一维直线型接地装置的工频接地电阻和冲击接地电阻的降低呈现出先快后慢的趋势,并且土壤电阻率越高,接地电阻降幅越明显。至于敷设位置,对于放射型接地极,土壤电阻率为100~2 000Ω·m时,对射线敷设就可以达到全部敷设的降阻效果。对于复合型接地极,仅射线敷设和仅垂直接地极敷设降阻效果相同。土壤电阻率为2 000Ω·m时,射线 ...
