Abstract:
... Eastern redcedar (Juniperus virginiana L.) is increasing in density in the eastern United States and expanding in range to the west, while western Juniperus species also are increasing and expanding, creating the potential for a novel assemblage. I estimated range expansion and intersection by comparing recent USDA Forest Service Forest Inventory and Analysis surveys (mean year = 2009) to the olde ...

Abstract:
... Six Tunisian medicinal plants were screened for their phenolic pools, antioxidant activities as well as for their anti-inflammatory and gastro-protective effects. A significant variability in phenolic composition and antioxidant capacities between species were observed. Myrtus communis L. exhibited the highest phenolic contents and composition as well as the best potential antioxidant capacities a ...

Abstract:
... Leaf longevity is an important adaptive strategy that allows plants to maximize photosynthetic carbon gain. Due to the difficulty of identifying overwintering bud scars and distinguishing the age sequence of twigs, leaf longevity is rarely studied in Cupressaceae species, which further limits our understanding of the leaf economic spectrum (LES) for these populations. Here, we investigated the lea ...

... The range of metals used for industrial purposes - electrical engineering, solar panels, batteries - has increased substantially over the last twenty years. Some of these emerging metals are the subject of geopolitical conflict and are considered critical as their unique properties make them irreplaceable. Many of these elements are poorly studied and their biogeochemical cycles still raise many q ...

Abstract:
... Foetid juniper (Juniperus foetidissima Willd.) is one of the most important coniferous species faced with multiple threats and it is difficult to propagate it with sexual reproduction. Therefore, the main goal of this study was finding appropriate salt concentrations and growth regulators for shoot regeneration and rooting of J. foetidissima under in vitro conditions and also shortening time of ma ...
... While polyploidy (whole‐genome multiplication) is generally considered rare in extant gymnosperms (with the exception of Ephedra, Ephedraceae), the occurrence of sporadic polyploid individuals belonging to various genera in the conifer family Cupressaceae has been reported in the literature. In addition, recent studies have revealed that polyploidy is not uncommon in the genus Juniperus (Cupressac ...

Abstract:
... The Yellowknife City Gold Project (YCGP), located close to the city of Yellowknife, Northwest Territories, Canada, is exploring and drilling the extension of the Au-bearing shear zones that host the Giant and Con Mines. A biogeochemical survey was conducted over the Crestaurum and Barney deposits, which are hosted within two well-known high Au grade shear zones at the YCGP. A total of 625 samples ...
... Nineteen essential oils (EOs) obtained from different plants have been evaluated for their potential in vitro anti-H1N1 influenza virus efficacy. Both multivariate analyses and bivariate correlation were performed to better understand how the composition influences the activity. The results evidenced that for the laboratory distilled EOs both rosemary hybrids (S. x lavandulaceus and S. x mendizaba ...
... Seed-based restoration of wildlife-important shrubs following wildfire is a management priority in many ecosystems. However, postfire restoration success is spatiotemporally variable and establishment from seed frequently fails in arid and semiarid rangelands. There may be opportunities to improve restoration success by taking advantage of small-scale spatial variability in environmental character ...
... Land mollusks are one of the most destructive agricultural pests worldwide, the management of which depends on synthetic molluscicides. However, many of these molluscicides are harmful to nontarget organisms. Hence, there is a need to develop alternative ecofriendly molluscicides that are less impactful toward nontarget organisms. So, an investigation into the fumigant toxicity and feeding deterre ...
... The aim of the study is to identify potential natural compounds against SARS-CoV-2 occurring in essential oils (EOs) following literature data attesting their anti-viral activity. The epidemic virus that started in December 2019 in Wuhan, China, has spread worldwide as a global pandemic. The interest in the development of drugs from natural products has increased greatly in recent decades. (EOs) h ...
... AIM: Colonization is a central topic in ecology and one of the cornerstones of island biogeography. Although the evolutionary history of island species is widely studied, the quantification of colonization is particularly challenging because the same area may be colonized multiple times by the same species, whereas initially successful colonization events may eventually be followed by extinction. ...

Abstract:
... Plant leaf lipids are complex mixtures, which may include n-alkanes, n-alkanols, fatty acids, phenolic compounds, phytosterols, terpenes, flavonoids, and alkaloids. Many of these compounds are also widely distributed in sediments and soils, preserving molecular and isotopic information that aids the study of past climatic and ecological variables. Sample preparation typically requires multi-step e ...
... Four magnetite nanoparticle (NP) samples have been greenly synthesized using four aqueous plant extracts, which are Artemisia herba-alba (L), Rosmarinus officinalis (L), Matricaria pubescens (L), and Juniperus phoenicia (L). The pH of these extracts are acidic (5.25, 5.05, 4.63, and 3.69, respectively). The synthesized samples were characterized by XRD, SEM, ATR-FTIR, and UV-Vis. This work aimed t ...

Abstract:
... The relative abundances of n-alkanes in plant-derived organic matter serve as reliable biomarkers in paleoecological studies, given that leaf wax characteristics in terrestrial plants are a function of the external environment. Owing to limited phylogenetic and geographic sampling in earlier studies, the relative weight of environmental factors and plant phylogeny on leaf wax production is yet to ...
... Palynological investigations on Gravettian coprolites of Abrigo do Lagar Velho (Vale do Lapedo, Leiria, Portugal) dated between ca. 30 to ca. 27.3 ka cal BP are presented. The palaeoecological data shows a semi-forested landscape with Pinus, Poaceae, Erica, Artemisia, Juniperus and Quercus as the dominant taxa. A diversity of trees, shrubs, and herbs is also noticeable, including broad-leaf trees, ...
... The medicinal plant Juniperus oxycedrus is less recognized for the diversity of its fungal endophytes and their potential to produce extracellular enzymes. The present study is the first report on the isolation and identification of a mesophilic endophytic strain JO-A, Preussia africana, from fresh stems of the J. oxycedrus endemic tree in the Ifrane region-Morocco, and the evaluation of its abili ...
... The genus Juniperus L. (Cupressaceae Bartl.) is consisting of about 75 species that are divided into sections Caryocedrus Endlicher, Sabina (Miller) Spach, and Juniperus (syn: sect. Oxycedrus Spach). Juniperus sabina L. from section Sabina is an important shrub for the maintenance of the ecosystem in mountainous regions and a source of medicinal compounds. The species is monoecious, rarely dioecio ...

Abstract:
... AIMS: This paper examines the water dynamics of a coastal dune plant community, addressing spatial and seasonal variations. We aimed to detect the patterns of water use by plants at the community level according to their distribution across a coastal dune gradient from beach to inland. METHODS: Five sites were established: upper beach, embryo-dune, slack, foredune, and inland. Eight perennial spec ...
... Although the contents of limiting elements in plants, such as nitrogen (N) and phosphorus (P), have been widely studied from subtropical to humid-temperate zones, the strategies used by coniferous species to allocation N and P in arid and semiarid forests remain unclear. In this study, samples of 545 leaves, 194 twigs, and 78 fine roots were collected from four coniferous species (Pinus tabuliform ...
