Enigmatic Nodal and Lefty gene repertoire discrepancy: Latent evolutionary history revealed by vertebrate‐wide phylogeny

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Homology in vertebrate body plans is traditionally ascribed to the high‐level conservation of regulatory components within the genetic programs governing them, particularly during the “phylotypic stage.” However, advancements in embryology and molecular phylogeny have unveiled the dynamic nature of gene repertoires responsible for early ...

Human decimation caused bottleneck effect, genetic drift, and inbreeding in the Canarian houbara bustard

open access: yesThe Journal of Wildlife Management, Volume 87, Issue 2, February 2023., 2023
We describe the genetic characteristics and dynamics, and the recent evolutionary history of the Canarian houbara bustard, an endemic to the Canary Islands. We identified high gene flow and two genetic units, with genetic bottlenecks and subsequent inbreeding in both of them, and propose potential management actions to avoid its extinction. Abstract An

Governance lessons from the Atlantic Forest to the conservation of the Amazon

open access: yesPerspectives in Ecology and Conservation, 2023
Brazilian forests critical are for climate, water, biodiversity, and ecosystem services. The Atlantic Forest and the Amazon are among the most important tropical forests of the world but have different conservation status.

Guideline‐directed medical therapy rates in heart failure patients with reduced ejection fraction in a diverse cohort

open access: yesESC Heart Failure, EarlyView.
Abstract Aims Guideline‐directed medical therapy (GDMT) is recommended for all patients with heart failure with reduced ejection fraction (HFrEF). Despite this, little data exist describing GDMT use in diverse, real‐world populations including the use of vasodilators, prescribed primarily to Black populations.

Oxygenation of a karst subterranean estuary during a tropical cyclone: mechanisms and implications for the carbon cycle

open access: yesLimnology and Oceanography, Volume 67, Issue 12, Page 2691-2705, December 2022., 2022
Abstract Seasonal precipitation affects carbon turnover and methane accumulation in karst subterranean estuaries, the region of coastal carbonate aquifers where hydrologic and biogeochemical processes regulate material exchange between the land and ocean.

Policy implementation and policy instruments: The underdeveloped dimensions of the four “political” American policy process theories. A Western European perspective

open access: yesEuropean Policy Analysis, EarlyView.
Abstract The fifth edition of “Theories of the Policy Process” represents a further step in consolidating these theories. However, four of them—Advocacy Coalition Framework, Multiple Streams Framework, Narrative Policy Framework, and Punctuated Equilibrium Theory—exhibit a few limitations in light of the characteristics of implementation and policy ...
