Responses to climate change – insights and limitations from herbaceous plant model systems
Published: 2025-03-24
Subjects: Ecology and Evolutionary Biology, Plant Sciences
Herbaceous plant species have been the focus of extensive, long-term research into climate change responses, but there has been little effort to synthesize results and predicted outlooks from different model species. We summarize research on climate change responses for eight intensively-studied herbaceous plant species. We establish generalities across species, examine limitations, interrogate [...]
Recovery of forest structural complexity during secondary succession in the tropics
Published: 2025-03-19
Subjects: Agricultural Science, Forest Sciences, Life Sciences, Plant Sciences, Terrestrial and Aquatic Ecology
Forest structural complexity is an essential determinant of forest ecosystem functions and biodiversity. The natural dynamics of structural complexity of tropical forests remain largely unexplored, especially for naturally regenerating forest during secondary succession. Better understanding the trajectories of forest structural complexity recovery is crucial to inform the development of forest [...]
Flavonol-regulating MYB underlies the evolution of red flowers in Iochroma (Solanaceae)
Published: 2025-03-13
Subjects: Ecology and Evolutionary Biology, Genetics and Genomics, Life Sciences, Plant Sciences
Anthocyanins, the pigments that give rise to blue, purple, red and pink colors in many flowers and fruits, are produced by the deeply conserved flavonoid biosynthesis pathway. The regulation of this pathway is thus fundamental for species differences in color across flowering plants, and a growing body of evidence implicates MYB transcription factors as key players activating or suppressing the [...]
Bridging data silos to holistically model plant macrophenology
Published: 2025-01-29
Subjects: Ecology and Evolutionary Biology, Life Sciences, Plant Sciences
● Phenological shifts to global climate change impact ecosystem functions. There are various data sources from which spatiotemporal, and taxonomic phenological data may be obtained: mobilized herbaria, community-science initiatives, observatory networks, and remote-sensing. However, analyses conducted to date have generally relied on single sources of data, thus treating alternative data sources [...]
Phytoremediation of Heavy Metals: Techniques, Challenges, and Prospects
Published: 2025-01-02
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Life Sciences, Plant Sciences
Heavy metals, characterized by their high atomic mass and density, can pose significant risks to soil, water, plants, and human health. Contamination sources include manufacturing activities, mining, farming practices, and improper waste management. Metals such as arsenic, mercury, lead, chromium, and cadmium are most toxic with health consequences that can result from organ dysfunction to [...]
Assessing Transparency and Reproducibility in Invasion Science
Published: 2024-12-06
Subjects: Botany, Ecology and Evolutionary Biology, Life Sciences, Plant Sciences
Policymakers and practitioners overseeing invasive species management depend on reliable research for guidance. Transparency and reproducibility are core features of reliable research, and prerequisites for successful study replication, but are evidently lacking in many science disciplines. Whether this shortfall characterizes invasion science remains unknown. We evaluated a sample of invasion [...]
Earlier and increased growth of tundra willows after a decade of growth in a warmer common garden environment
Published: 2024-11-07
Subjects: Biology, Botany, Ecology and Evolutionary Biology, Life Sciences, Plant Biology, Plant Sciences, Terrestrial and Aquatic Ecology
1. The expansion of woody shrubs, known as shrubification, is one of the most widely observed patterns of vegetation change in the tundra. Yet, we do not know the relative importance of plant plasticity and genetic change in determining shrub responses to warming. Plastic responses to the environment can be rapid, while genetic differentiation is much slower. 2. We established a common garden [...]
Niche dynamics of alien plant species in Mediterranean Europe
Published: 2024-11-03
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences, Plant Sciences
Aim Humans have spread plants globally for millennia, inadvertently causing ecological disruptions. However, biological invasions also provide a unique opportunity to study the process of niche dynamics, through which species adapt their niche when confronted with novel environments. Focusing on the Mediterranean Basin, we assessed 1) which traits favour niche dynamics, and 2) whether niche [...]
BON in a Box: An Open and Collaborative Platform for Biodiversity Monitoring, Indicator Calculation, and Reporting
Published: 2024-10-28
Subjects: Animal Sciences, Biodiversity, Biology, Ecology and Evolutionary Biology, Forest Sciences, Life Sciences, Marine Biology, Plant Sciences
The Convention on Biological Diversity’s Kunming-Montreal Global BiodiversityFramework (GBF) sets ambitious goals to protect and restore biodiversity. It includes a Monitoring Framework that mandates countries to track progress toward these goals using indicators that summarize biodiversity trends. Calculating indicators is challenging for countries due to technical barriers, lack of available [...]
Patterns of fruit production in tropical forests are shifting with negative outnumbering positive trends
Published: 2024-10-25
Subjects: Biodiversity, Ecology and Evolutionary Biology, Forest Sciences, Life Sciences, Plant Sciences
The impacts of climate change and anthropogenic disturbance are increasingly evident in the structure and demographics of tropical forests, yet the response of tree reproduction remains poorly understood. As fruit and seed production is the first step in forest recruitment, this gap is critical to understanding tropical forest resilience. Tropical fruits are important in diets of numerous [...]
Leveraging ResNet-50 for Precision Toxicity Classification in Plants: A Vision-Based Approach to Safeguard Public Health
Published: 2024-10-04
Subjects: Environmental Engineering, Plant Sciences
The classification of toxic and non-toxic plants plays an important role in ensuring public safety, especially in agriculture, food safety, and health. Correct identification of these plants can prevent accidental poisoning and promote ecological protection. In this paper, we investigate the application of the ResNet-50 model for the classification of toxic and non-toxic plants. Leveraging the [...]
Collapse and recovery of livestock systems shape fire regimes on the Eurasian steppe: a review of ecosystem and biodiversity implications
Published: 2024-09-04
Subjects: Biodiversity, Botany, Natural Resources and Conservation, Plant Sciences, Sustainability
Shifts in fire regimes can trigger rapid changes in ecosystem functioning and biodiversity. We synthesize evidence for patterns, causes and consequences of recent change in fire regimes across the Eurasian steppes, a neglected global fire hotspot. Political and economic turmoil following the break-up of the Soviet Union in 1991 triggered abrupt land abandonment over millions of hectares and a [...]
Phenological Patterns of Woody Plant Species in a Tropical Dry Forest, Bannerghatta National Park, Bengaluru
Published: 2024-06-27
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Forest Sciences, Life Sciences, Plant Sciences
Phenology is the study of the timing of recurring natural stages in the life cycle of an organism. These natural stages, such as the plant's reproductive cycles, are being affected by the changing climate. The current study aims to understand the effect of weather parameters on the phenology of dry forests in Bannerghatta National Park. Two transects with 504 reproductively mature individuals [...]
Tundra vegetation community, not microclimate, controls asynchrony of above and belowground phenology
Published: 2024-06-24
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Plant Sciences, Plant Biology, Plant Sciences, Terrestrial and Aquatic Ecology
The below-ground growing season often extends beyond the above-ground growing season in tundra ecosystems. However, we do not yet know where and when this occurs and whether these phenological asynchronies are driven by variation in local vegetation communities or by spatial variation in microclimate. Here, we combined above- and below-ground plant phenology metrics to compare the relative [...]
