Quantifying landscape‐level biodiversity change in an island ecosystem: a 50‐year assessment of shifts in the Hawaiian avian community

open access: yesEcography, EarlyView.
Hawaii has experienced profound declines in native avifauna alongside the introduction of numerous bird species. While site‐specific population studies are common, landscape‐level analyses of avian population dynamics are rare, particularly in island ecosystems. To address this gap, we used a density surface model to create a spatio‐temporal projection

Vegetation photosynthetic phenology dataset in northern terrestrial ecosystems

open access: yesScientific Data, 2023
Vegetation phenology can profoundly modulate the climate-biosphere interactions and thus plays a crucial role in regulating the terrestrial carbon cycle and the climate.

Spatial and temporal exposure to climatic extremes shape butterfly thermal physiology and vulnerability to recent climate change

open access: yesEcography, EarlyView.
Whether the limits of species' ranges and their seasonal activity reflect physiological tolerance of climatic extremes is a long‐standing question in ecology and has implications for species' responses to recent climate change. We explored these associations in butterflies, using thermal tolerance traits and traits describing geographic distribution ...

Spatiotemporal Variation Characteristics of Extreme Precipitation in Henan Province Based on RClimDex Model

open access: yesAtmosphere
Global warming has led to an increasing frequency and intensity of extreme precipitation events worldwide. The extreme precipitation of Henan Province in central China usually occurs in summer, with the climate transition from the northern subtropical to

Heptapleurum assamicum (Araliaceae): A New Species From Assam, India

open access: yesFeddes Repertorium, EarlyView.
ABSTRACT A new species, Heptapleurum assamicum (Araliaceae), is described and illustrated from Assam, India. It was discovered during floristic documentation conducted in the Kopili River basin, in the Dima Hasao and West Karbi Anglong districts. The species is distinguished by a unique combination of morphological characters. Detailed comparisons with

Temperature and photoperiod drive spring phenology across all species in a temperate forest community.

open access: yesNew Phytologist, 2018
Accurate predictions of spring plant phenology with climate change are critical for projections of growing seasons, plant communities and a number of ecosystem services, including carbon storage.

Resist!: Sustaining forest carbon sequestration and wood production after insect disturbance

open access: yesFrontiers in Ecology and the Environment, EarlyView.
Disturbances from insect pests threaten ecologically and economically important goods and services supplied by forests, including wood production and carbon sequestration. We highlight the factors that influence these services’ resistance, a term quantifying the initial response to disturbance.

Dynamic identification of snow phenology in the Northern Hemisphere [PDF]

open access: yesThe Cryosphere
Snow phenology characterizes the cyclical changes in snow and has become an important indicator of climate change in recent decades. Changes in snow phenology can significantly impact climate and hydrological conditions.

Climate-induced phenology shifts linked to range expansions in species with multiple reproductive cycles per year

open access: yesNature Communications, 2019
Advances in phenology (the annual timing of species’ life-cycles) in response to climate change are generally viewed as bioindicators of climate change, but have not been considered as predictors of range expansions. Here, we show that phenology advances

DNA Barcoding Reveals Cryptic Diversity and Informs Conservation Priorities in Chinese Firmiana Species (Malvaceae) Using Genome Skimming Data DNA条形码揭示中国梧桐属 (锦葵科) 隐存多样性及保护优先级:来自基因组浅层测序数据的证据

open access: yesIntegrative Conservation, EarlyView.
Accurate species identification is critical for conserving endangered Firmiana trees in China. However, morphological similarities among closely related Firmiana species complicate its taxonomic identification. We conducted genome skimming on 62 samples representing all 10 Chinese species and discovered nrITS as the optimal DNA barcode, achieving 100 ...
