Seroprevalence of COVID-19 infection in a rural district of Tamil Nadu: A population-based seroepidemiological study by Kannan G, Aruna P, Nithyavikasini N, Kumar Raja M

“…A higher proportion of susceptible, relatively higher IFR, and a poor tertiary health-care network stress the importance of sustaining the public health measures and promoting early access to the vaccine are crucial to preserving the health of this population. Low population density, good housing, adequate ventilation, limited urbanization combined with public, private, and local health leadership are critical components of curbing future respiratory pandemics.…”

Distribución geográfica y depredación de Porites lobata (Anthozoa: Scleractinia) en la costa occidental de México by Héctor Reyes Bonilla, Tito Livio Pérez Vivar, James T Ketchum Mejía

“…However, predator damage seems to be greater in Nayarit-Jalisco-Colima than in the oceanic islands, possibly because corallivore fishes were less abundant in the latter. Population density of coral bioeroders (sponges, polychaetes, spinculans and bivalves) in P. lobata eas similar and sometimes higher at the Revillagigedos than in coastal sites, suggesting the possibility of a primary productivity diffeerential among those locations.…”

Sheridan, Jerald Brotzge, Howard H. Chang, Eric K. Stern, Zhijian Guo, Guanghui Dong, Ramune Reliene, Yuantao Hao, Shao Lin

“…Results: Consistent across different outcomes, we found predictors representing greater urbanization, particularly, the proportion of residents having access to public transportation (importance ranging from 4.9–15.6%), population density (3.3–16.1%), per capita income (2.3–10.7%), and the density of public infrastructure (0.8–8.5%), were associated with a higher possibility of risk elevation following power outages. …”
