Grass functional traits reflect the long history of fire and grazers in the savannas of Texas

American Journal of Botany, Volume 112, Issue 10, October 2025.
Abstract Premise Understanding relationships among grass traits, fire, and herbivores may help improve conservation strategies for savannas that are threatened by novel disturbance regimes. Emerging theory, developed in Africa, emphasizes that functional traits of savanna grasses reflect the distinct ways that fire and grazers consume biomass ...

Climate‐driven ecological stability as a globally shared cause of Late Quaternary megafaunal extinctions: the Plaids and Stripes Hypothesis

Biological Reviews, Volume 94, Issue 1, Page 328-352, February 2019., 2019
ABSTRACT Controversy persists about why so many large‐bodied mammal species went extinct around the end of the last ice age. Resolving this is important for understanding extinction processes in general, for assessing the ecological roles of humans, and for conserving remaining megafaunal species, many of which are endangered today.

Megafauna extinction, tree species range reduction, and carbon storage in Amazonian forests [PDF]

, 2016
During the Late Pleistocene and early Holocene 59 species of South American megafauna went extinct. Their extinction potentially triggered population declines of large-seeded tree species dispersed by the large-bodied frugivores with which they co ...

Legacy of the Lost and Pressure of the Present: Malagasy Plant Seeds Retain Megafauna Dispersal Signatures but Downsize Under Human Pressure

Ecology Letters, Volume 28, Issue 9, September 2025.
Using structural equation models, we show that Malagasy assemblages with higher human pressure have smaller maximum seed sizes, especially through downsizing of extant frugivores. Furthermore, among assemblages with ‘mega‐seeded’ plants (i.e., seeds that cannot be swallowed by any extant Malagasy frugivore), larger seed sizes are associated with larger

The Hydroclimate and Environmental Response to Middle Miocene Warming in the Southwestern USA: Stable Isotope Evidence

Paleoceanography and Paleoclimatology, Volume 40, Issue 5, May 2025.
Abstract Predictions for the southwestern US with warming often suggest increased aridity. We investigate the sedimentary record of the Miocene Climate Optimum and Transition (MCO and MCT; ∼17–14 Ma) in northern New Mexico to understand the impact of warmer global temperatures and higher pCO2 on southwestern US hydroclimate. The MCO and MCT comprised a

Fossil proboscidean remains from Bolt's Farm and other Transvaal cave breccias [PDF]

, 1993
Proboscidean remains are very rare in the Transvaal cave breccias and the few specimens recovered are generally fragmentary but deserve description because of their potential value in correlation and dating.

Diversity of limb long bone morphology among proboscideans: how to be the biggest one in the family

Papers in Palaeontology, Volume 10, Issue 6, November/December 2024.
Abstract From its first small representatives to its later giant species, the Order Proboscidea evolved increasingly large forms. Limb long bones are heavily affected by shifts in body mass, and this is especially true in proboscideans, in which an increase in body mass is associated with a reorientation of the limb into the parasagittal plane ...

Contexts, Connections, and Clovis: Opportunities for Collaboration Between Information Scientists and Archaeologists [PDF]

, 2018
Our poster discusses the potential for collaboration between information scientists and archaeologists. In particular, this poster uses a case study of Clovis spear points to illustrate the importance of collaboration between the two disciplines in order

The onset of Pliocene–Early Pleistocene fluvial aggradation in the Southeastern Alpine Foreland (Velenje Basin, Slovenia) and its paleoenvironmental implications

Journal of Quaternary Science, Volume 39, Issue 5, Page 691-709, July 2024.
ABSTRACT In this study, we focused on the Pliocene–Early Pleistocene fluvial terraces in the Velenje Basin and reconstructed the morphostratigraphy, sedimentary depositional environment, provenance and age of the gravel deposits using geomorphological, sedimentological, petrographic and chronological analyses.

The “Tambla” (Humuya) Gomphothere (Honduras): The first report of fossil vertebrates in Central America El Gonfoterio de “Tambla” (Humuya , Honduras): El primer registro de un vertebrado fósil en América Central

Revista Geológica de América Central, 2011
In 1858, American geologist Joseph LeConte published the first scientific report of vertebrate fossils (mastodon, bison and horse) from Central America a brief record of a “mastodon bed” near the old village of Tamblain Honduras.
