Evidence for Range Expansion and Origins of an Invasive Hornet Vespa bicolor (Hymenoptera, Vespidae) in Taiwan, with Notes on Its Natural Status

open access: yesInsects, 2021
The invasive alien species (IAS) Vespa bicolor is the first reported hornet that has established in Taiwan and is concerning as they prey on honeybee Apis mellifera, which leads to colony losses and public concerns.

Complete mitochondrial genome of Manis pentadactyla pentadactyla (Mammalia: Pholidota), an endemic subspecies of Chinese pangolin: mitogenome characterisation and phylogenetic implications [PDF]

open access: yesBiodiversity Data Journal, 2021
The Chinese pangolin Manis pentadactyla is critically endangered because of over-exploitation and illegal trafficking and includes three subspecies. However, the taxonomic status of the three subspecies of the Chinese pangolin has not been well resolved,

Rapid Light-Response Curve of Chlorophyll Fluorescence in Terrestrial Plants: Relationship to CO2 Exchange among Five Woody and Four Fern Species Adapted to Different Light and Water Regimes

open access: yesPlants, 2021
The rapid light response of electron transport rate (ETRR), obtained from chlorophyll fluorescence parameters by short illumination periods (10–30 s) at each light level, can provide a rapid and easy measurement of photosynthetic light response in plants.

Effect of geographic isolation on genetic variation and population structure of Euphrasia nankotaizanensis, a threatened endemic alpine herb in Taiwan

open access: yesHeliyon, 2023
Euphrasia nankotaizanensis (Orobanchaceae) is a rare alpine herb that is endemic to Taiwan. Only four small populations remain in Xue, Nanhu, and Cilai Mountains of Taiwan.

Distinct migratory and non-migratory ecotypes of an endemic New Zealand eleotrid (Gobiomorphus cotidianus) – implications for incipient speciation in island freshwater fish species [PDF]

open access: yes, 2008
Background: Many postglacial lakes contain fish species with distinct ecomorphs. Similar evolutionary scenarios might be acting on evolutionarily young fish communities in lakes of remote islands.

New insights into polyploid evolution and dynamic nature of Ludwigia section Isnardia (Onagraceae)

open access: yesBotanical Studies, 2023
Background While polyploids are common in plants, the evolutionary history and natural dynamics of most polyploid groups are still unclear. Owing to plentiful earlier systematic studies, Ludwigia sect.

The vascular plant species endemic or nearly endemic to Puebla, Mexico

open access: yesBotanical Sciences, 2023
Background: Knowledge of endemism in a region (natural or political) is fundamental to determining natural biogeographic regions and establishing conservation priorities. Questions: How many vascular plant species are endemic to the state of Puebla? What is the geographic distribution of endemism in the state?

Uncovering endemism in a lake of invasive species introgression [PDF]

open access: yesMolecular Ecology, 2021
Species distributions are rapidly being altered by human globalisation and movement. As species are moved across biogeographic boundaries, human-mediated secondary contacts between historically allopatric taxa may promote hybridisation between closely related native and introduced species.
