POPULAR ENTREPRENEURSHIP: A Grammar of Moral Economy in Contemporary Urban Peripheries

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract This article examines how popular entrepreneurship operates as a cultural grammar that disrupts established practices of wageless life in urban peripheries. Drawing on four years of ethnographic research conducted in São Paulo, it analyses entrepreneurial discourses not simply as ideological impositions, but as ambivalent mediations of ...

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

open access: yesIntegrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

Availability of a Keystone Plant Resource Reduces Niche Overlap and Drives Distinct Species‐Specific Changes in Niche Breadth Among Small Rodents

open access: yesIntegrative Zoology, EarlyView.
We investigated how three rodent species respond to the seasonal availability of Araucaria angustifolia seeds. While Oligoryzomys spp. increased seed consumption and abundance during seed production, the more insectivorous Akodon paranaensis maintained a broader diet.

The Earliest Feathers from the Lower Cretaceous Dabeigou Formation of North Hebei: Implications for the Early Evolution of the Jehol Biota

open access: yesIntegrative Zoology, EarlyView.
This study reports two isolated feather fossils from the Lower Cretaceous Dabeigou Formation in northeastern China. Morphological analyses identified them as the earliest known feathered theropods (potentially including avian) in the Jehol Biota. This finding reveals a complex ecosystem at the dawn of the Jehol Biota, bridging the temporal and faunal ...

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement

open access: yesGeophysical Monograph Series, Page 27-82., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Hidden Losses: Assessing the Risk of Coextinction Among Ectoparasitic Flies and Their Bat Host Species in Brazil

open access: yesAnimal Conservation, EarlyView.
The potential impact of bat species extinction on the number of their ectoparasitic fly species, based on interaction data for Brazil. As bat host species are removed over time, more connected species (green) would experience steeper declines and lead to greater ectoparasite losses when compared to a random extinction model (gray).
