Published: April 17, 2025

During explorations of the ginger flora Bismarck Archipelago in 2013 and 2023, we made collections genus Alpinia sensu lato, some which had unusually elongated cincinni composed distichously arranged bracteoles present paper conclude that these document a distinct species new to science, arachniformis A.D.Poulsen. The choice epithet refers spider-like appearance inflorescence. Similar morphology is found other lineages Alpinia, but our molecular analysis using Internal Transcribed Spacer (ITS) marker established close relationship with A. oceanica from differs by having more flowers linear labellum. An ink drawing colour plates, information on distribution habitat, provisional conservation status are provided for as well key Archipelago.

Birds and barriers: present and past seas are dominant correlates of avian turnover in the Indo-Australian Archipelago

Frontiers of Biogeography, Journal Year: 2023, Volume and Issue: 15(2)

Published: April 25, 2023

The Indo-Australian Archipelago (IAA) is a geologically dynamic area of high biotic endemism that spans the continental shelves Sunda and Sahul intervening oceanic islands. We provide comprehensive quantitative assessment how bird communities are structured across IAA using beta diversity indices. focus on three key questions. Are islands Wallacea biogeographically cohesive unit or more heterogeneous transition zone? Is rich biota New Guinea East Melanesian most closely linked to Sunda, Wallacea? What geographic environmental correlates structuring region does this compare with determinants plant diversity? measure dissimilarity species composition between eleven major areas within new compilation distribution data calculate taxonomic at species, genera, family levels. To recent analyses plants, we analysed potential turnover, focusing proximity, sea barriers, land area, climatic variation. also used connectivity estimate minimum number connection events needed explain current shared taxa. found recently connected by have lower than Additionally, avifaunas little cohesion, reflecting their complex geological history.

From earthquakes to island area: multi‐scale effects upon local diversity

Ecography, Journal Year: 2024, Volume and Issue: 2024(5)

Published: March 29, 2024

Tropical forests occupy small coral atolls to the vast Amazon basin. They occur across bioregions with different geological and climatic history. Differences in area bioregional history shape species immigration, extinction diversification. How this effects local diversity is unclear. The Indonesian archipelago hosts thousands of tree whose coexistence should depend upon these factors. Using a novel dataset 215 forest plots, fifteen islands ranging from 120 785 000 km 2 , we apply Gaussian mixed models examine simultaneous environment, earthquake proximity, island bioregion for trees ≥ 10 cm diameter at breast height. We find that declines precipitation seasonality increases area. Accounting environment show westernmost Sunda has greater than Wallacea, which turn easternmost Sahul. However, when model includes activity (here proximity major earthquakes), differences are reduced. Overall, results indicate multi‐scale, current historic dictate diversity. These multi‐scale drivers not be ignored studying biodiversity gradients their impacts ecosystem function.

The Sequential Direct and Indirect Effects of Mountain Uplift, Climatic Niche, and Floral Trait Evolution on Diversification Dynamics in an Andean Plant Clade

Systematic Biology, Journal Year: 2024, Volume and Issue: 73(3), P. 594 - 612

Published: March 30, 2024

Why and how organismal lineages radiate is commonly studied through either assessing abiotic factors (biogeography, geomorphological processes, climate) or biotic (traits interactions). Despite increasing awareness that both processes may have important joint effects on diversification dynamics, few attempts been made to quantify the relative importance timing of these factors, their potentially interlinked direct indirect effects, lineage diversification. We here combine assessments historical biogeography, geomorphology, climatic niche, vegetative, floral trait evolution test whether jointly, in isolation, explain dynamics a Neotropical plant clade (Merianieae, Melastomataceae). After estimating ancestral areas changes niche disparity over time, we employ Phylogenetic Path Analyses as synthesis tool eleven hypotheses individual rates. find strongest support for colonization uplifting Andes during mid-Miocene rapid explaining burst rate Merianieae.

Beetle evolution illuminates the geological history of the World's most diverse tropical archipelago

Ecography, Journal Year: 2023, Volume and Issue: 2023(12)

Published: Oct. 10, 2023

The geologically‐complex Indo–Australian–Melanesian archipelago (IAMA) hosts extraordinarily high levels of species richness and endemism has long served as a natural laboratory for studying biogeography evolution. Nonetheless, its geological history the provenance evolution biodiversity remain poorly understood. Here, we provide scenario IAMA informed by time‐calibrated molecular phylogeny 1006 Trigonopterus weevils – an exceptionally diverse radiation regionally‐endemic flightless beetles. Moreover, performed statistical biogeographic analysis examined timing patterns in accumulation lineages residing priori‐defined geographic units comprising IAMA. We estimate that originated Australia during early Paleogene. Subsequent rapid diversification area present‐day Papuan Peninsula suggests presence proto‐Papuan islands middle Eocene; New Guinea North Coast Ranges were colonized late Eocene, followed Highlands Bird's Head Peninsula. inferred terrestrial habitat Moluccas Sulawesi Oligocene subsequent colonization Sundaland Lesser Sunda Islands. Caledonia Samoa from Peninsula, their faunas also diverged Oligocene. These biota‐informed time estimates are compatible with data region shed new light on paleogeography, even where evidence been lost to erosion. Beetle thus appears have closely tracked IAMA, revealing uniquely well‐resolved view regional biogeography.

Journal of Heredity, Journal Year: 2023, Volume and Issue: 114(6), P. 669 - 680

Published: Aug. 17, 2023

Abstract We announce the assembly of first de novo reference genome for California Scrub-Jay (Aphelocoma californica). The genus Aphelocoma comprises four currently recognized species including many locally adapted populations across Mesoamerica and North America. Intensive study has revealed novel insights into evolutionary mechanisms driving diversification in natural systems. Additional history this group will require continued development high-quality, publicly available genomic resources. extracted high molecular weight DNA from a female northern generated PacBio HiFi long-read data Omni-C chromatin conformation capture data. used these to generate partially phased diploid assembly, consisting two pseudo-haplotypes, scaffolded them using inferred physical proximity information more complete pseudo-haplotype (arbitrarily designated “Haplotype 1”) is 1.35 Gb total length, highly contiguous (contig N50 = 11.53 Mb), (BUSCO completeness score 97%), with comparable scaffold sizes chromosome-level avian genomes (scaffold 66.14 Mb).

Island life accelerates geographic radiation in the white‐eyes (Zosteropidae)

Ibis, Journal Year: 2022, Volume and Issue: 165(3), P. 817 - 828

Published: Dec. 22, 2022

White‐eyes are an iconic avian radiation of small passerines that mainly distributed across the eastern hemisphere tropics and subtropics. Species diversity white‐eyes is particularly high on oceanic islands, many species restricted to single islands or island groups. The rate diversification ranks them among fastest radiations known in birds, but whether their accelerated was result repeatedly colonizing remains unexplored. We used a newly estimated timetree for nearly all zosteropids phylogenetic comparative methods estimate compare rates between continental lineages. show have similar extinction rates, yet higher speciation compared with white‐eyes. In addition, we find transitions from continents. Our results importance such as Wallacean Melanesian archipelagos Indo‐Pacific, facilitating within this remarkable clade.
