AbstractEpidemics can particularly threaten certain sub-populations. For example, for SARS-CoV-2, the elderly are often preferentially protected. For diseases of plants and animals, certain sub-populations can drive mitigation because they are intrinsically more valuable for ecological, economic, socio-cultural or political reasons. Here we use optimal control theory to identify strategies to optimally protect a “high value” sub-population when there is a limited budget and epidemiological uncertainty. We use protection of the Redwood National Park in California in the face of the large ongoing state-wide epidemic of sudden oak death (caused by Phytophthora ramorum) as a case study. We concentrate on whether control should be focused entirely within the National Park itself, or whether treatment of the growing epidemic in the surrounding “buffer region” can instead be more profitable. We find that, depending on rates of infection and the size of the ongoing epidemic, focusing control on the high value region is often optimal. However, priority should sometimes switch from the buffer region to the high value region only as the local outbreak grows. We characterise how the timing of any switch depends on epidemiological and logistic parameters, and test robustness to systematic misspecification of these factors due to imperfect prior knowledge.

A new species of Cyrtodactylus is described from the Truong Son (Annamite mountain range) of Quang Binh Province in central Vietnam. It is characterized by 3–5 transversal dorsal bands between the limb insertions, a neckband reaching the posterior margin of eye, 19–20 irregular longitudinal rows of dorsal tubercles, forelimbs with tubercles, 47–50 longitudinal rows of ventrals at midbody, 9–11 precloacal pores in an angular series in males and 16–27 enlarged precloacal scales in both sexes, 20–23 lamellae below the 4th toe, a segmented tail, and lacking of a distinct ventrolateral fold, a precloacal groove and femoral pores, as well as transversally enlarged subcaudal plates. The new species is known only from the karst forests of Phong Nha - Ke Bang National Park. Preliminary data on its natural history are provided.
