Biodiversity post-2020: Closing the gap between global targets and national-level implementation
National and local governments need to step up efforts to effectively implement the post-2020 global biodiversity framework of the Convention on Biological Diversity to halt and reverse worsening biodiversity trends. Drawing on recent advances in interdisciplinary biodiversity science, we propose a framework for improved implementation by national and subnational governments. First, the identification of actions and the promotion of ownership across stakeholders need to recognize the multiple values of biodiversity and account for remote responsibility. Second, cross-sectorial implementation and mainstreaming should adopt scalable and multifunctional ecosystem restoration approaches and target positive futures for nature and people. Third, assessment of progress and adaptive management can be informed by novel biodiversity monitoring and modeling approaches handling the multidimensionality of biodiversity change

Speciation of arsenic in milk from cows fed seaweed
Background: Including seaweed in cattle feed has gained increased interest, but it is important to take into account that the concentration of toxic metals, especially arsenic, is high in seaweed. This study investigated the arsenic species in milk from seaweed-fed cows.
Results: Total arsenic in milk of control diets (9.3 ± 1.0 μg As kg-1, n=4, dry mass) were significantly higher than seaweed-based diet (high-seaweed diet: 7.8 ± 0.4 μg As kg-1, p < 0.05, n=4, dry mass; low seaweed diet: 6.2 ± 1.0 μg As kg-1, p < 0.01, n=4, dry mass). Arsenic speciation showed that the main species present were arsenobetaine (AB) and arsenate (As(V)) (37% and 24% of the total arsenic, respectively). Trace amounts of dimethylarsinic acid (DMA) and arsenocholine (AC) have also been detected in milk. Apart from arsenate being significantly lower (p < 0.001) in milk from seaweed-fed cows, than in milk from the control group, other arsenic species showed no significant differences between groups.
Conclusion: The lower total arsenic and arsenate in seaweed diet groups indicates a possible competition of uptake between arsenate and phosphate and the presence of AC indicates a reduction of AB occurred in the digestive tract. Feeding a seaweed blend (91% Ascophyllum nodosum and 9% Laminaria digitata) does not raise As-related safety concerns for milk
