(Uploaded by Plazi for the IPBES Invasive Alien Species Assessment) Multiple human-mediated pathways in the marine environment provide ample opportunities for new and potentially harmful species to spread into high-value natural areas. Often, these areas are remote and reactive measures to an invasion prove to be difficult, therefore a more precautionary and proactive approach is necessary. The Fiordland Marine Area (FMA) is largely unmodified and has a unique and productive underwater environment. Following an amendment in 2012 to the Biosecurity Act 1993 the Fiordland Marine Guardians and an inter-agency government group worked to develop and implement the Fiordland Marine Regional Pathway Management Plan (FMPP), whose overarching objective is to prevent the introduction and spread of invasive marine species to the FMA. The plan involves three key elements to manage invasive species vectors: (1) that vessel owners and operators hold a current Clean Vessel Pass for their vessel; (2) that the vessel meets clean vessel standards including hull biofouling, gear biofouling and residual seawater requirements; and (3) that owners and operators maintain and can present records on the steps taken to meet the clean vessel standards. The plan was made operative in 2017, and to date, uptake has generally been positive with only a small number of compliance issues. The adoption of this plan is largely due to an integrated iwi, community and agency management approach which has encouraged engagement and participation from the Fiordland stakeholders. The ongoing success of this programme will rely on the commitment from the partnering central and local government agencies to improve and refine the plan, and on a general elevation in the importance of marine biosecurity management nationwide. Ideally, the plan will significantly reduce the risk of further marine bioinvasions within the FMA.

Инфильтратив ўпка туберкулёзи (ИЎТ) туберкулёзнинг энг кенг тарқалган клиник шаклларидан бири бўлиб, иш қобилиятидаги аҳоли орасида кўп учрайди. Сўнгги ўн йилликларда туберкулёзнинг клиник кечишида коморбид ва мультиморбид ҳолатлар сонининг ортиши кузатилмоқда. Бу ҳолат, айниқса, ошқозон яра касаллиги ва ВИЧ-инфекция билан биргаликда кечганда, касалликнинг клиник манзараси, диагностикаси ва даволаш натижаларига салбий таъсир кўрсатади. ВИЧ-инфекция фонида иммун тизимининг босқичма-босқич сусайиши туберкулёзнинг кам симптомли, атипик ва суст кечишига олиб келади. Натижада туберкулёз кеч ташхисланади, даволаш муддати узаяди ва асоратлар хавфи ортади. Шу билан бирга, ВИЧ-инфекцияли беморларда ошқозон-ичак тракти касалликлари, хусусан ошқозон ва ўн икки бармоқли ичак яра касаллиги кенг тарқалган. Ошқозон яра касаллигининг асосий этиологик омилларидан бири бўлган Helicobacter pylori инфекцияси туберкулёз билан касалланган беморларда ҳам юқори частотада учрайди. Айниқса, H. pylori-негатив ошқозон яра касаллиги билан инфильтратив ўпка туберкулёзи биргаликда кечганда клиник прогноз ноқулай ҳисобланади.

Succinoraphidia and ‘Mesoraphidiidae’It is now clear that the Mesozoic ‘Mesoraphidiidae’ is a paraphyletic group, which includes in particular the stem lineages leading to extant Raphidiidae and Inocelliidae (Makarkin & Archibald 2014). The venation of Succinoraphidia is more similar to that of some ‘Mesoraphidiidae’ than the venation of any genus of Raphidiidae. Moreover, there are a few mesoraphidiids in which all diagnostic character states of Succinoraphidia are found (except for the structure of the pterostigma). It is characteristic of some minute species from the early Late Cretaceous, e.g., Grimaldiraphidia luzzii (Grimaldi, 2000) from the Turonian New Jersey amber; Nanoraphidia electroburmica Engel, 2002 and Burmoraphidia reni Liu et al., 2016 from the early Cenomanian Burmese amber. These genera are considered to belong to the tribe Nanoraphidiini (Bechly & Wolf-Schwenninger 2011; Liu et al. 2016). But the structure of their pterostigma differs from that of Succinoraphidia. It lacks the crossvein 2scp-r at the proximal end of the pterostigma (B. reni) or incorporated branches of RA within pterostigma (G. luzzii and N. electroburmica). However, the pterostigma of some other ‘Mesoraphidiidae’ from Burmese amber (e.g., Dolichoraphidia engeli Liu et al., 2016) is very similar to that of Raphidiidae with a long pterostigma, including Succinoraphidia, i.e., it possesses the crossvein 2scp-r at the proximal end of the pterostigma and the incorporated branch of RA within the pterostigma (see Liu et al. 2016: Fig. 4). The venation of Dolichoraphidia engeli differs from that of Raphidiidae only by the number of discoidal cells: one in D. engeli and normally two in all Raphidiidae, except some species, which have one discoidal cell in the hind wings, e.g., those of Harraphidia Steinmann, 1963 (see Monserrat & Papenberg 2006: Figs 1–4).Judging from great similarity of the venation of Nanoraphidiini (and similar genera of the Late Cretaceous ‘Mesoraphidiidae’) and Succinoraphidia, among the former may be present a stem group leading to Raphidiidae.

Angiotensin converting enzyme 2 (ACE2) is a key regulator of the renin‐angiotensin system, but also the functional receptor of the severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2). Based on structural similarity with other γ‐secretase (γS) targets, we hypothesized that ACE2 may be affected by γS proteolytic activity. We found that after ectodomain shedding, ACE2 is targeted for intramembrane proteolysis by γS, releasing a soluble ACE2 C‐terminal fragment. Consistently, chemical or genetic inhibition of γS results in the accumulation of a membrane‐bound fragment of ectodomain‐deficient ACE2. Although chemical inhibition of γS does not alter SARS‐CoV‐2 cell entry, these data point to a novel pathway for cellular ACE2 trafficking.

This article presents an exploratory theoretical model termed the Focus–Yield Equation, developed to articulate how structured focus, time allocation, distraction cost, consistency, and efficiency jointly contribute to meaningful performance outcomes. Although inspired by behavioral science, productivity research, and systems thinking, the framework is intentionally positioned as a conceptual theory awaiting empirical validation. The objectives of this work are: To propose a structured mathematical representation of human productive output. To invite academic and professional critique. To enable iterative refinement through empirical study. To stimulate interdisciplinary exploration across management science, psychology, cognitive performance research, and applied productivity engineering. The author welcomes constructive review, challenge, and collaboration.

(Uploaded by Plazi for the IPBES Invasive Alien Species Assessment) Abstract Protected areas are the cornerstone of biodiversity conservation. However, alien species invasion is an increasing threat to biodiversity, and the extent to which protected areas worldwide are resistant to incursions of alien species remains poorly understood. Here, we investigate establishment by 894 terrestrial alien animals from 11 taxonomic groups including vertebrates and invertebrates across 199,957 protected areas at the global scale. We find that <10% of protected areas are home to any of the alien animals, but there is at least one established population within 10-100 km of the boundaries of 89%-99% of protected areas, while >95% of protected areas are environmentally suitable for establishment. Higher alien richness is observed in IUCN category-II national parks supposedly with stricter protection, and in larger protected areas with higher human footprint and more recent designation. Our results demonstrate that protected areas provide important protection from biological invasions, but invasions may become an increasingly dominant problem in the near future.
