Local Climatic Effects on Colonisation and Extinction Drive Changes in Mountain Butterfly Communities

open access: yesDiversity and Distributions, Volume 31, Issue 1, January 2025.
ABSTRACT Aim The capacity of cool refugia to protect cold‐adapted species against climate change may depend on both their initial climatic conditions and how quickly these change. We test how local climatic conditions influence mountain butterfly communities via their effects on colonisation and local extinction.

Niche‐based approach to explore the impacts of environmental disturbances on biodiversity

open access: yesConservation Biology, Volume 38, Issue 6, December 2024.
Abstract Globally, species are increasingly at risk from compounding threatening processes, an increasingly prominent driver of which is environmental disturbances. To facilitate effective conservation efforts following such events, methods that evaluate potential impacts across multiple species and provide landscape‐scale information are needed to ...

Evaluating drivers of recent large whale strandings on the East Coast of the United States

open access: yesConservation Biology, Volume 38, Issue 6, December 2024.
Abstract Anthropogenic stressors threaten large whales globally. Effective management requires an understanding of where, when, and why threats are occurring. Strandings data provide key information on geographic hotspots of risk and the relative importance of various threats.

Constructing sympatry networks to assess potential introgression pathways within the major oak sections in the contiguous US states

open access: yesPLANTS, PEOPLE, PLANET, Volume 6, Issue 6, Page 1437-1452, November 2024.
Increasing evidence indicates gene flow commonly occurs between closely related species in diverse plant genera and can involve numerous species. Here, we present a simple method to quantify and characterize the potential for gene flow among “sympatric” species (they share some part of their geographic distribution), using oaks as a case study.

Sediment-Deficit Sink-Zone Morphodynamics in Oceanic Island Dune Systems: Integration of Field Data and Remote Sources in the Macaronesian Region

open access: yesRemote Sensing
Coastal erosion has become a significant problem in the context of global warming and sea level rise. The combination of these factors which, in some cases, produces sedimentary deficit, is causing flooding problems that affect coastal ecosystems such as

The Neoproterozoic Mozambique Belt in the Gol Mountains (N Tanzania): Structural Analysis of Amphibolite and Granulite‐Facies Nappe Tectonites From a Crustal Orogenic Channel

open access: yesTectonics, Volume 43, Issue 11, November 2024.
Abstract A structural analysis of the Gol Mountains of North Tanzania is presented in which we identify and characterize a sheet‐like deformation‐localization zone of regional scale. Syn‐metamorphic rock‐deformation within the localization zone gave rise to widespread tectonite development under high‐T in lower‐mid crustal realms.
