ABSTRACT The present study examines the manner in which several whole‐tree water transport properties scale with species‐specific variation sapwood storage capacity. hypothesis that constraints on relationships between capacitance and other relations characteristics lead to predictable scaling intrinsic behaviour was investigated. Samples of from four tropical forest canopy tree species selected represent a range wood density, size architecture, taxonomic diversity were used generate...
Robust thermal dissipation sensors of variable length (3 to 30 cm) were developed overcome limitations the measurement radial profiles sap flow in large-diameter tropical trees with deep sapwood. The effective measuring custom-made was reduced 1 cm at tip a thermally nonconducting shaft, thereby minimizing influence nonuniform flux density across Sap measured different depths and circumferential positions trunks four Parque Natural Metropolitano canopy crane site, Panama City, Republic...
In large trees, the daily onset of transpiration causes water to be withdrawn from internal storage compartments, resulting in lags between changes and sap flow at base tree. We measured time courses flow, hydraulic resistance, plant potential stomatal resistance co-occurring tropical forest canopy trees with trunk diameters ranging 0.34–0.98 m, determine how total use reliance on stored scaled size. also examined effects scale tree properties apparent constants for response fluctuating...
Abstract This study examined the guidelines issued by top 50 U.S. universities regarding use of Generative AI (GenAI) in academic and administrative activities. Employing a mixed methods approach, research combined topic modeling, sentiment analysis, qualitative thematic analysis to provide comprehensive understanding institutional responses GenAI. Topic modeling identified four core topics: Integration GenAI Learning Assessment, Visual Multimodal Media, Security Ethical Considerations...
Tropical forests are becoming increasingly alien-dominated through the establishment of timber plantations and secondary forests. Despite widespread recognition that afforestation results in increased evapotranspiration lower catchment yields, little is known impacts on water balance relative to native forest. Native forest trees have been claimed use conservatively enhance groundwater recharge faster-growing alien species, this argument should motivate preservation restoration. However,...
Light availability strongly affects leaf structure of the distinctive ontogenetic forms Eucalyptus globulus Labill. ssp. globulus. Late-maturing plants from St. Marys, Tasmania and early maturing Wilsons Promontory, Victoria (hereafter referred to as Prom.) were grown for 9 months in 100, 50 or 10% sunlight. Growth, biomass area significantly reduced when Provenance differences minimal despite retention juvenile form by Tasmanian throughout study. The time taken initiation vegetative phase...
Leaf characteristics of Eucalyptus globulus Labill. ssp. vary in response to plant genotype, ontogenetic position and environmental conditions. Glasshouse-grown seedlings from provenances at St Marys, Tasmania, Wilsons Promontory, Victoria, produced seedling leaves for 10 nodes before producing juvenile form. Tasmanian provenance began produce after 18 weeks, 4 weeks earlier than Promontory seedlings. continued foliage, whereas transitional 33 weeks. Successive ranged the adult leaf form...
Recent advances in digital technology, coupled with rapidly increasing interest the creation and dissemination of digitized specimen data for use broad-scale research by botanists other organismal scientists, have encouraged development a variety new opportunities botanical sciences (e.g., Page et al., 2015; Soltis, 2017). It is now increasingly possible to collect, use, re-use, share more easily effectively. With advent U.S. National Science Foundation's Advancing Digitization Biodiversity...
Juvenile and adult leaves of the heteroblastic species Eucalyptus globulus Labill. ssp. did not show active diurnal orientation toward or away from incident radiation. a late-maturing sapling Tasmanian provenance were evenly distributed in all azimuth sectors. In contrast, an early-maturing same age Wilsons Promontory, Victoria had predominance leaf blades facing east west. Mid-vein blade angles juvenile non-random with overall vertical declination leaves. Both types intercepted greater...
The quality of biodiversity data publicly accessible via aggregators such as GBIF (Global Biodiversity Information Facility), the ALA (Atlas Living Australia), iDigBio (Integrated Digitized Biocollections), and OBIS (Ocean Biogeographic System) is often questioned, especially by research community. Data Quality Interest Group, established Standards (TDWG) GBIF, has been engaged in four main activities: developing a framework for assessment management using fitness use approach; defining core...
Mesophyll structure has been associated with the photosynthetic performance of leaves via regulation internal light and CO 2 profiles. Differences in mesophyll chlorophyll distribution within three ontogenetically different leaf types Eucalyptus globulus ssp. were investigated. Juvenile are blue‐grey color, dorsiventral (adaxial palisade layer only), hypostomatous, approximately horizontal orientation. In contrast, adult dark green isobilateral abaxial palisade), amphistomatous, nearly...
Leaves of six clonal individuals Eucalyptus camaldulensis Dehnh. from five Australian locations were compared. Two clones Wooramel, WA while single lines Dongara, WA, Erudina, SA, Murray Bridge, SA and Silverton, NSW. Principal component analysis climatic factors for the locations, derived by BIOCLIM, provided patterns temperature, radiation atmospheric moisture, which might be expected to influence morphological anatomical features leaves. Isozyme indicated that two Wooramel closely...
Rainforests in the South Pacific hold a considerable amount of plant diversity, with rates species endemism >80% some countries. This diversity is rapidly disappearing under pressure from logging, clearing for agriculture or mining, introduced pests and diseases other anthropogenic sources. Ex situ conservation techniques offer means to limit loss diversity. Seed banking considered most efficient cost effective these but applicable only seed capable tolerating desiccation cold storage....
This editorial celebrates the launch of journal Natural History Collections and Museomics outlines its primary goals: to serve as a platform for exploring roles functions natural history museums, addressing their opportunities challenges, investigating applications scientific collections they curate. The associated skilled workforce powerful means study global diversity and, crucially, foster knowledge, description, conservation, potential.
Abstract Samples of Juniperus thurifera L. were collected from the Atlas Mts., Morocco, northern and southern Spain, Pyrenees, France, Fench Alps Corse Isaland, France. The leaf oils analyzed found to be polymorphic for several major compounds (sabinene, limonene, linalool, piperitone, linalyl acetate sesquiterpenes). In general, Moroccan trees higher in sabinene, γ-terpinene, cis-sabinene hydrate terpinen-4-ol, but lower δ-2-carene, piperitone than Europe. Analysis based on Random Amplified...
Abstract Twenty one accessions of vetiver (Vetiveria zizanioides (L.) Nash, sterile, oil type) and Khus (V. zizanioides, fertile, non-oil were analyzed by the use random amplified polymorphic DNAs (RAPDs). Nineteen clustered strongly around cultigen, Sunshine. Three accessions, Khus, Northern India, Kassel, Germany, Guang Dong, China loosely not closely related to sterile producing vetivers. Thirteen grown in test plots Florida, USA, Nepal Portugal. The largest growth was recorded Nepal,...
Abstract Herbarium collections shape our understanding of the world’s flora and are crucial for addressing global change biodiversity conservation. The formation such natural history collections, however, not free from sociopolitical issues immediate relevance. Despite increasing efforts representation colonialism in herbaria have received comparatively less attention. While it has been noted that majority plant specimens housed North, extent this disparity rigorously quantified to date....
Abstract The highly polymorphic taxon Metrosideros polymorpha ('ohi'a) is the most abundant endemic tree in Hawai'i, occupying a wide but fragmented range of habitats across Federal, State, and privately managed lands. Morphological character states 342 herbarium specimens from island Hawai'i distributed five recognised varieties ordinal space, intermediate pheno‐types were prevalent. random amplified DNA (RAPD) analyses undertaken for 10 individuals at 3 sites on Hawai'i.
