Predictions on the efficacy of marine reserves for benefiting fisheries differ in large part due to considerations of models
of either intra- or inter-cohort population density regulating fish recruitment. Here, I consider both processes acting on
recruitment and show using a bioeconomic model how for many fisheries density dependent recruitment dynamics interact with
harvest costs to influence fishery profit with reserves. Reserves consolidate fishing effort, favoring fisheries that can
profitably harvest low-density stocks of species where adult density mediates recruitment. Conversely, proportion coastline
in reserves that maximizes profit, and relative improvement in profit from reserves over conventional management, decline
with increasing harvest costs and the relative importance of intra-cohort density dependence. Reserves never increase profit
when harvest cost is high, regardless of density dependent recruitment dynamics. I quantitatively synthesize diverse results
in the literature, show disproportionate effects on the economic performance of reserves from considering only inter- or intra-cohort
density dependence, and highlight fish population and fishery dynamics predicted to be complementary to reserve management.

Malaria is a substantial global health burden with 229 million cases in 2019 and 450,000 deaths annually. Plasmodium vivax is the most widespread malaria-causing parasite putting 2.5 billion people at risk of infection. P. vivax has a dormant liver stage and therefore can exist for long periods undetected. Its blood-stage can cause severe reactions and hospitalization. Few treatment and detection options are available for this pathogen. A unique characteristic of P. vivax is that it depends on the Duffy antigen/receptor for chemokines (DARC) on the surface of host red blood cells for invasion. P. vivax employs the Duffy binding protein (DBP) to bind to DARC. We first de novo designed a three helical bundle scaffolding database which was screened via protease digestions for stability. Protease-resistant scaffolds highlighted thresholds for stability, which we utilized for selecting DARC mimetics that we subsequentially designed through grafting and redesign of these scaffolds. The optimized design small helical protein disrupts the DBP:DARC interaction. The inhibitor blocks the receptor binding site on DBP and thus forms a strong foundation for a therapeutic that will inhibit reticulocyte infection and prevent the pathogenesis of P. vivax malaria. 相似文献

Summary New and used cellulosic air filters for HVAC systems including those treated with antimicrobials were suspended in vessels with a range of relative humidities (55–99%) and containing non-sterile potting soil which stimulates fungal growth. Most filters yielded fungi prior to suspension in the chambers but only two of 14 nontreated filters demonstrated fungal colonization following use in HVAC systems. Filters treated with antimicrobials, particularly a phosphated amine complex, demonstrated markedly less fungal colonization than nontreated filters. In comparison with nontreated cellulosic filters, fungal colonization of antimicrobial-treated cellulosic filters was selective and delayed. 相似文献

Landomycin A was found to inhibit the uptake of [3H]thymidine into DNA in murine smooth muscle cells indicating decreased DNA synthesis. Subsequent studies showed that landomycin A inhibits cell cycle progression. 相似文献

Belonolaimus longicaudatus has been reported as damaging both potato (Solanum tuberosum) and cotton (Gossypium hirsutum). These crops are not normally grown in cropping systems together in areas where the soil is infested with B. longicaudatus. During the 1990s cotton was grown in a potato production region that was a suitable habitat for B. longicaudatus. It was not known how integrating the production of these two crops by rotation or double-cropping would affect the population densities of B. longicaudatus, other plant-parasitic nematodes common in the region, or crop yields. A 3-year field study evaluated the viability of both crops in monocropping, rotation, and double-cropping systems. Viability was evaluated using effects on population densities of plant-parasitic nematodes and yields. Rotation of cotton with potato was found to decrease population densities of B. longicaudatus and Meloidogyne incognita in comparison with continuous potato. Population densities of B. longicaudatus following double-cropping were greater than following continuous cotton. Yields of both potato and cotton in rotation were equivalent to either crop in monocropping. Yields of both crops were lower following double-cropping when nematicides were not used. 相似文献
