Concrete jungle to urban oasis: evaluating scale, vegetation cover, and aggregation of urban greenspaces on wildlife

open access: yesWildlife Biology, EarlyView.
Urban greenspaces are a haven for wildlife in densely populated cities. Wildlife use greenspaces for resource acquisition, shelter, and travel across urbanized landscapes. Greenspace metrics such as herbaceous or woody landcover, size, patchiness, and human land use influence species richness.

Space and resource use by American crow Corvus brachyrhynchos in an area endemic for chronic wasting disease

open access: yesWildlife Biology, EarlyView.
American crow Corvus brachyrhynchos is a common species throughout North America. Crows play a role in the ecology of multiple diseases and a single laboratory experiment has shown the potential for crows to pass infectious prions, such as those associated with chronic wasting disease (CWD), in their feces after being force‐fed with infected material ...

A Simplified Theory of External Occulters for Solar Coronagraphs

open access: yesThe Astrophysical Journal
We present a first-principles analytic treatment of modern multivane occulters in circular (coronagraph) and linear (heliospheric imager) geometry, develop a simplified theory that is useful for designing and predicting their performance, explain certain

Desegregationist Pan‐African Spiritual Strivings: Du Bois, the Black Church and the Critique of Imperialism*

open access: yesJournal of Religious History, EarlyView.
Abstract This article argues that W. E. B.

Mitragynine Pseudoindoxyl Withdrawal Treated with Macro-Dosed Buprenorphine Induction: A Case Report and Review of the Literature

open access: yesPsychoactives
Background: Mitragynine pseudoindoxyl (MP) is a semi-synthetic kratom metabolite increasingly sold online and over-the-counter, marketed misleadingly as “kratom” or “7-OH,” despite lacking FDA approval and safety data in humans. Methods: This case report

Reduced fertilization regimes could boost biocontrol service without reducing crop yield

open access: yesInsect Science, EarlyView.
Fertilization level influences pest control effectiveness in tomato crops. High fertilization increases plant growth and aphid density but reduces the performance of the parasitoid Aphidius ervi. In contrast, the predator Adalia bipunctata maintains consistent aphid suppression regardless of fertilization regime.

Comparing verbenone‐based repellents for ambrosia beetle management in eastern apple orchards

open access: yesAgricultural and Forest Entomology, EarlyView.
Non‐native ambrosia beetles (Xylosandrus germanus, X. crassiusculus, Anisandrus maiche) damage high‐density apple orchards across the eastern United States, motivating the search for selective, semiochemical‐based repellent strategies. Across Ohio, New York and Pennsylvania, three verbenone formulations, sachets, SPLAT® VERB and a test SPLAT ...
