Sedimentary Mercury Enrichments as a Tracer of Large Igneous Province Volcanism

open access: yesGeophysical Monograph Series, Page 247-262., 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.

Patterns of understorey bird diversity across Amazonian forests: survey effort and range maps predict local species richness

open access: yesEcography, EarlyView.
Species diversity typically increases from higher to lower latitudes, but the regional‐scale variation along this geographic gradient remains unclear. It has been suggested that species diversity throughout Amazonia generally increases westward toward the Andes, but this pattern and its environmental determinants require further investigation for most ...

How Do Citizens Respond to Government Measures in Times of Crisis? Narrative Meaning‐Making of Agency, Responsibility, and Compliance During the COVID‐19 Pandemic in Ecuador

open access: yesEuropean Journal of Social Psychology, EarlyView.
ABSTRACT Citizens’ responses to policies depend on narrative meaning‐making. Through the lens of the COVID‐19 pandemic in Ecuador, this study addresses calls for increased insights into how processes of responding to government measures function during societal crises and ruptures.

Trends and Challenges of Sustainable Rural Tourism in the Face of Artificial Intelligence: A Bibliometric Analysis

open access: yesSustainable Development, EarlyView.
ABSTRACT This study explores the development of sustainable rural tourism through a multidisciplinary approach, integrating economic, technological, and environmental perspectives. It aims to analyze research trends, key contributors, and the role of artificial intelligence (AI) in shaping the future of rural tourism.

Phylogeny and historical biogeography of the Pachira sensu lato clade (Bombacoideae, Malvaceae) with a new infrageneric classification

open access: yesTAXON, EarlyView.
Abstract We explore phylogenetic relationships within the Pachira sensu lato clade (Bombacoideae, Malvaceae), test the monophyly of the genera Eriotheca and Pachira, and investigate their biogeographic history. The Pachira s.l. clade comprises ca. 72 species that traditionally have been placed in Eriotheca and Pachira. We sampled ca. 79% of its species

A novel circumscription and classification for Neurolaeneae (Asteraceae)

open access: yesTAXON, EarlyView.
Abstract Neurolaeneae (Asteraceae) have a complicated taxonomic history. The tribe was described in 1927, but subsequently disregarded in 1977, and later reinstated as a tribe following a large‐scale phylogenetic analysis of Asteraceae in 2002. To date, this tribe has remained poorly studied and it has never been the subject of a comprehensive ...

Egalitarians despite themselves: envy and leadership in Ecuadorian Amazonia Égalitaires malgré eux : envie et leadership en Amazonie équatorienne

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
The Shuar of Ecuadorian Amazonia once pursued eminence through warfare and vision quests. While vision quests have been retained, today – settled in villages – they seek eminence through economic success and political leadership. This article examines an apparent paradox: whilst envy suspicions pervade public life, they legitimize rather than level ...

Revealing patterns of endemism in the transatlantic family Chelodesmidae (Polydesmida: Diplopoda)

open access: yesCladistics, EarlyView.
Abstract With fossil records dating back to the Silurian/Late Ordovician, millipedes stand out as one of the earliest terrestrial animal groups. Their limited vagility and high endemism make them valuable tools for formulating and testing biogeographic hypotheses, including those related to macro‐vicariance events.

Homo luzonensis and the role of homoplasy in the morphology of hominin insular species

open access: yesCladistics, EarlyView.
Abstract Homo luzonensis lived during the upper Pleistocene in the northern Philippines, east of the Wallace line. The few specimens attributed to this species show a mosaic of plesiomorphies for the genus Homo and apomorphies found in upper Pleistocene Homo species.

Where water meets rock: Ecological niches and diversity hotspots of hygropetric beetles in the Neotropics

open access: yesEcological Entomology, EarlyView.
First continental‐scale synthesis of hygropetric beetle diversity and distribution across Neotropical highlands. Climatic and topographic gradients structure regional assemblages and niche overlap. Ecological convergence suggests adaptation to similar conditions across disjunct regions.
