Analysis Of The Variables Affecting Plant Species Richness In Deserts, Eli R. Kallison, Ellen Thompson, Maddison Keen, Rusty Newman Oct 2020

Analysis Of The Variables Affecting Plant Species Richness In Deserts, Eli R. Kallison, Ellen Thompson, Maddison Keen, Rusty Newman

IdeaFest: Interdisciplinary Journal of Creative Works and Research from Cal Poly Humboldt

There are many hypotheses that attempt to explain patterns of species diversity in different environments. Deserts are a great place to study changes in species richness because they are relatively nutrient bare and exhibit low precipitation. This barebones environment means that slight shifts in climate and geography may lead to clear changes in species richness. We investigate how temperature, precipitation, water and light availability, latitude, elevation and other variables affect plant species richness in 20 deserts.

Persons As Plants: Ecopsychology And The Return To The Dream Of Nature, Monica Gagliano Mar 2013

Persons As Plants: Ecopsychology And The Return To The Dream Of Nature, Monica Gagliano

Landscapes: the Journal of the International Centre for Landscape and Language

Abstract. In this article, I examine human-plant perceptions and interactions in terms of developing a new perspective on the perception and the actions of people towards plants. By combining my scientific understanding of the biological world and my own experiences working with plant shamans, storytellers and mystics from around the world, I engage with the idea that the hierarchical structure by which Western science defines the variety of life forms as ‘primitive’ or ‘more evolved’ is at the root of the current environmental crisis and I argue that the solution to it rests in a change of this very perspective.

The Diversity And Ecology Of Epiphytic Lichens In “Evolution Canyon” Ii, Lower Nahal Keziv, Upper Western Galilee, Israel, Marina Temina, Mikhail P. Andreev, Sophia Barinova, Eviatar Nevo

Turkish Journal of Botany

Different populations of epiphytic lichens were studied in a microsite in Lower Nahal Keziv, Western Upper Galilee, Israel, which is designated as an "Evolution Canyon" (EC) II. In all, 24 lichen species from 5 orders, 11 families, and 17 genera were registered, about one third of them (7 species) for the first time in Israel. Species richness was higher on the warmer, drier, climatically more fluctuating and biotically more heterogeneous south-facing slope (SFS). Most lichens of EC II were mesophytic and photo-indifferent species; however, humid and shaded habitats of the north-facing slope (NFS) and valley bottom (VB) were characterised by …


Study Of Seasonal Influences On Algal Biodiversity In The River Yarqon (Central Israel) By Bio-Indication And Canonical Correspondence Analysis (Cca), Sophia Barinova, Moti Tavassi Jan 2009

Study Of Seasonal Influences On Algal Biodiversity In The River Yarqon (Central Israel) By Bio-Indication And Canonical Correspondence Analysis (Cca), Sophia Barinova, Moti Tavassi

Turkish Journal of Botany

In our research conducted in the River Yarqon during 2003-2006, we identified 313 taxa of algae and cyanobacteria belonging to 8 taxonomical divisions. Out of these 313 taxa, 268 taxa (85.6%) were indicators of environmental conditions that characterised the river water as alkaline with medium mineralisation. In the rainy and dry seasons the algal taxonomic compositions were very different, with prevailing diatoms in the winter and cyabobacteria and greens in summer. Bio-indication shows that the taxonomic preference for the self-purification process was more intensive during the rainy season, while the low level of river water in the dry season stressed …

Aliso: A Journal of Systematic and Floristic Botany

We investigated the phylogenetic relationships of the endemic New Zealand (NZ) species of Festuca (Poaceae, Pooideae) by assessing sequence variation from the nuclear internal transcribed spacers (ITS) and a chloroplast intergenic spacer (trnL–trnF) and by measuring DNA content using flow cytometry. The ITS and trnL–trnF data sets were congruent in showing that the NZ species of Festuca have two origins. One group, containing F. coxii, F. luciarum, F. multinodis, and F. ultramafica, is closely related to Festuca sect. Aulaxyper. The other group includes a clade of five endemic …


Speciation In Duckweeds (Lemnaceae): Phylogenetic And Ecological Inferences, Daniel J. Crawford, Elias Landolt, Donald H. Les, Rebecca T. Kimball Jan 2006

Speciation In Duckweeds (Lemnaceae): Phylogenetic And Ecological Inferences, Daniel J. Crawford, Elias Landolt, Donald H. Les, Rebecca T. Kimball

Aliso: A Journal of Systematic and Floristic Botany

Species of duckweeds (Letnnaceae) that were resolved as sister taxa in a phylogeny based on combined molecular and non-molecular data were compared for morphological, physiological, and ecological attributes to infer factors important in the initial divergence leading to speciation. The ability to survive extreme conditions such as desiccation and cold temperatures is the most common difference identified between species. Two morphological characters facilitating survival in extreme environments are production of special resting buds called turions and increased seed production. The prevalent geographic pattern for species pairs consists of one restricted species occurring on the periphery of a more widespread taxon; …

An Investigation On The Morphology, Anatomy And Ecology Oforiganum Onites L.1, Ahmet Gönüz, Bilkan Özörgücü

Turkish Journal of Botany

Possible variations in the morphology, anatomy, ecology and phenology of Origanum onites L. ( Lamiaceae/Labitae) in rela-tion to altitudinal variations was studied together with the differences in etheric oil content. A decrease in the stem and lower leaf lengths was observed compared with an increase in the cortical area and vascular tissues in parallel with altitudinal increases. The number and size of stomata also varied with this factor. Etheric oil content was found to be different in relation to altitude.


Systematic And Ecological Wood Anatomy Of Californian Scrophulariaceae. Ii. Penstemon Subgenus Saccanthera, David C. Michener Jan 1986

Systematic And Ecological Wood Anatomy Of Californian Scrophulariaceae. Ii. Penstemon Subgenus Saccanthera, David C. Michener

Aliso: A Journal of Systematic and Floristic Botany

Wood anatomy of nonarboreal Scrophulariaceae is little studied, yet such information is needed to understand the evolution of woodiness in the family and order. Description and quantification of wood characters of six species (nine taxa) of Penstemon subgenus Saccanthera show that these woods are specialized. Paedomorphic features include the standard declining-to-level curve of vessel element length by age, and (in several samples) a pronounced tendency to raylessness. Variation in ray characteristics is as great within as between species, suggesting that unsampled populational variation in ray characteristics may be present. Cells intermediate between fibers and nonseptate parenchyma are present and complement …
