Geophysical investigation of the Santa Marta impact structure—Piauí State, Brazil

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract The Santa Marta impact structure in northeastern Brazil, recognized as a partially preserved complex crater, was investigated through an integrated geophysical study employing magnetotelluric (MT) and gravity methods. Our research provides constraints on the crater's subsurface architecture.

Cretaceous paleoceanography

open access: yes, 1995
The modern ocean is comprised of four units: an equatorial belt shared by the two hemispheres, tropical subtropical anticyclonic gyres, mid-latitude belts of water with steep meridional temperature gradients, and polar oceans characterized by cyclonic gyres.

Resilience of floral scent emission after florivory

open access: yesPlant Biology, EarlyView.
Florivory is thought to affect floral traits, impacting pollination. However, our data suggest a stability in post‐florivory scent emission, which may guarantee the maintenance of pollinator visitation regardless of florivory, indicating a resilience of natural systems with multiple and simultaneous interactions. Created in BioRender. Tunes, P.

Effects of low‐tech, process‐based restoration on riparian plant communities and soil moisture of streams in the Northern Great Plains (NGP) of the United States

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Process‐based restoration is novel in livestock production systems of the Northern Great Plains (NGP), and limited region‐specific evidence can impede adoption. We investigated the effects of methods such as beaver dam analogs (BDAs) on NGP plant communities.
