“…In the past 10 yr, extensive collections of seeds together with specimens of wild plant species have been carried out throughout China by numerous collaborators (Sun, ). The number of wild species in the germplasm bank exceeds 10 000, providing additional specimens for the study (Hart et al ., ; Yu et al ., ). In total, 4637 specimens with fruits from 109 legume species were used for final analysis, all collected between 1900 and 2013 from across China (Supporting Information Fig.…”

A widely observed pollinator decline around the world has led to the prediction that terrestrial ecosystems could be disrupted as plant pollination suffers, but declining pollination success has not been tested rigorously in wild plants, and it still remains unclear how pollination success of plant species responds differently in the context of pollinator decline.By viewing the number of seeds per pod as a quantitative measure of successful pollination, we examined seed pods in 4637 herbarium specimens of 109 obligately outcrossing legumes collected over the past century.We found that only 13 species showed significant temporal change with nine of those as an increase. None of the three subfamilies of legumes showed a consistent trend, and the subfamily Papilionoideae with the most specialized flowers, had increasing seed number per pod more often than decreasing.We conclude that legume pollination in China shows no sign of disruption and the effects of plant-pollinator disruption may be more complicated than simplistic predictions have allowed.

“…Incredibly, they incredibly found 75% of these species exhibited significant change in the past 150 years since introduction. Other studies have analyzed morphological shifts in the context of climate change for leaves (e.g., Guerin et al 2012;Stropp et al 2017;Sritharan et al 2021) and floral traits (e.g., Bontrager and Angert 2016;Yu et al 2016). Paleobotanists commonly measure leaf morphological traits, such as leaf size, shape, and serration, to estimate past temperatures from plant fossils (e.g., Peppe et al 2011).…”

Herbaria as Big Data Sources of Plant Traits

Herbarium specimens have long been a cornerstone of taxonomic research but are only recently being recognized for their potential as a source of spatially and temporally extensive data on plant functional traits. Many researchers in trait-based disciplines remain surprisingly unaware of this powerful use of herbaria, including functional ecologists and evolutionary biologists alike. This review brings together disparate studies to synthesize the past, current, and potential future uses of specimens as functional trait data sources, answering: 1) What insights have been made to date using specimens? (including traits measured, approaches used, research questions answered); 2) What new trait-based insights can be made from herbarium specimens? (including potential contributions to global trait databases and recent advancements such as machine learning and high throughput phenotyping); and 3) How can inherent limitations and collection biases be addressed when using specimens in unanticipated ways? (including new analytical approaches and improved methods for collecting). I conclude by identifying what is needed to foster the future of herbaria as big data sources of plant traits. Most notably, plant collecting must be continued, expanded beyond predominantly systematists, and intentionally revised with downstream trait measurements in mind. Further, community-wide standards are needed to integrate otherwise disconnected data and directly link newly derived measurements back to specimen records. Specimens serve as reliable (and necessary) sources of phenotypic data, enabling us to answer questions across phylogenetic, temporal, and spatial dimensions otherwise not possible. Herbaria should be embraced as centers for functional trait research.

“…Notably, climate change will affect the vegetation phenology which will subsequently impact the plant diversity. For example, changes in seasonal temperatures will alter the flowering time of plants, with increases in annual average temperature overall resulting in an earlier flowering time (Hart et al, 2014;Yu et al, 2016).…”

Vegetation Response to Holocene Climate Change in the Qinling Mountains in the Temperate–Subtropical Transition Zone of Central–East China

Global warming is having a profound influence on vegetation and biodiversity patterns, especially in alpine areas and high latitudes. The Qinling Mountain range is located in the transition zone between the temperate and subtropical ecosystems of central–east China and thus the vegetation of the area is diverse. Understanding the long-term interactions between plant diversity and climate change can potentially provide a reference for future landscape management and biodiversity conservation strategies in the Qinling Mountains region. Here, we use a pollen record from the Holocene sediments of Daye Lake, on Mount Taibai in the Qingling Mountains, to study regional vegetation changes based on biomes reconstruction and diversity analysis. Temperature and precipitation records from sites close to Daye Lake are used to provide environmental background to help determine the vegetation response to climate change. The results indicate that climate change was the main factor influencing vegetation and palynological diversity in the Qinling Mountains during the Holocene. The cold and dry climate at the beginning of the early Holocene (11,700–10,700 cal yr BP) resulted in a low abundance and uneven distribution of regional vegetation types, with the dominance of coniferous forest. During the early Holocene (10,700–7,000 cal yr BP), temperate deciduous broadleaf forest expanded, palynological diversity and evenness increased, indicating that the warm and humid climate promoted vegetation growth. In the middle Holocene (7,000–3,000 cal yr BP), the climate became slightly drier but a relatively warm environment supported the continued increase in palynological diversity. After ∼3,000 cal yr BP, palynological diversity and the evenness index commenced a decreasing trend, in agreement with the decreased temperature and precipitation in the Qinling Mountains. It’s noteworthy that human activity at this time had a potential influence on the vegetation. During the past few centuries, however, palynological diversity has increased along with the global temperature, and therefore it is possible that in the short-term ongoing climatic warming will promote vegetation development and palynological diversity in the area without human interference.
