Landscape resistance constrains hybridization across contact zones in a reproductively and morphologically polymorphic salamander [PDF]

open access: yesScientific Reports, 2021
Explicitly accounting for phenotypic differentiation together with environmental heterogeneity is crucial to understand the evolutionary dynamics in hybrid zones.

Cooperative Stabilization of Close-Contact Zones Leads to Sensitivity and Selectivity in T-Cell Recognition [PDF]

open access: yesCells, 2021
T cells are sensitive to 1 to 10 foreign-peptide-MHC complexes among a vast majority of self-peptide-MHC complexes, and discriminate selectively between peptide-MHC complexes that differ not much in their binding affinity to T-cell receptors (TCRs ...

Local niches explain coexistence in environmentally-distinct contact zones between Western Mediterranean vipers [PDF]

open access: yesScientific Reports, 2023
Species’ ecological niches are frequently analysed to gain insights into how anthropogenic changes affect biodiversity. Coping with these changes often involves shifts in niche expression, which can disrupt local biotic interactions.

Hybridization patterns in two contact zones of grass snakes reveal a new Central European snake species [PDF]

open access: yesScientific Reports, 2017
Recent studies found major conflicts between traditional taxonomy and genetic differentiation of grass snakes and identified previously unknown secondary contact zones. Until now, little is known about gene flow across these contact zones.

Trait Variation and Spatiotemporal Dynamics across Avian Secondary Contact Zones [PDF]

open access: yesBiology
A secondary contact zone (SCZ) is an area where incipient species or divergent populations may meet, mate, and hybridize. Due to the diverse patterns of interspecific hybridization, SCZs function as field labs for illuminating the on-going evolutionary ...

Molecular signatures of adaptive introgression and selection in contact zones of closely related pine species (Pinus genus) [PDF]

open access: yesBMC Plant Biology
Background Natural hybridization plays a key role in shaping genetic diversity, local adaptation, and the dynamics of speciation through interspecific gene flow. Hybrid zones serve as valuable natural systems for studying these processes.

Hybridization as a biodiversity driver: The case of Veronica × gundisalvi

open access: yesMediterranean Botany, 2021
Hybridization is an important mechanism in plant evolution, which contributes to the adaptability and biological diversity of species in fundamental ways. Based on morphological data, Veronica × gundisalvi Sennen (Veronica orsiniana × V.

Humanist Limits in the Material Phenomenology of Religion [PDF]

open access: yesJournal for the Study of Religion, 2019
This article tracks a shared methodological tension within the work of a few classic phenomenologists, based on an epistemological juxtaposition at the heart of their enquiry.

Adaptation as Migration

open access: yesInterfaces, 2022
This essay explores the implications of using migration as a metaphor for adaptation. These implications become legally and morally fraught when adaptation is regarded not simply as migration but as emigration or immigration, two activities more narrowly
