Updates in the flora of the Maltese Islands (Central Mediterranean)
No full textDuring the last 5 years, this author has been involved in the research and exploration of the flora of the
Maltese islands in order to create and update the website http://www.maltawildplants.com. This paper
consists of several important discoveries of new populations of very rare or endangered floral species for
the Maltese Islands which were recorded during field surveys to collect material for this website. It also
includes the species Calendula bicolor Rafin., which is a new record for the Maltese islands.peer-reviewe
Flora Tristan Life Stories
No full textFlora Tristan is best known as a nineteenth century French social critic and reformer. Her writings can be seen as a precursor to Marxism and Feminism. Flora Tristan: Life Sories by Susan Grogan, investigates the life of Flora Tristan through an exploration of the way she represented herself in her own writings. The author also examines the portrayal of Flora Tristan in paintings and literature. Rather than adopting a chronological approach, the author surveys the personae of Flora Tristan through thematic chapters on her roles as author, socialist, traveller and "Mother of the Workers". She places Flora Tristan in the context of contemporary debates and ideas, adding to our understanding of the times in which Flora Tristan lived. Flora Tristan: Life Stories argues that Flora Tristan's self-representations were attempts to claim a role of authority and significance not open to women in the nineteenth century. This authoritative study also engages with attempts to re-evaluate the writing of biography and to explore the meaning of an individual life in historical context.Book Cover -- Title -- Copyright -- ContentsFlora Tristan is best known as a nineteenth century French social critic and reformer.

A comparison of the moss floras of Chile and New Zealand
No full textChile and New Zealand share a common stock of 181 species of mosses in 94 genera and 34 families. This number counts for 23.3% of the Chilean and 34.6% of the New Zealand moss flora. If only species with austral distribution are taken into account, the number is reduced to 113 species in common, which is 14.5% of the Chilean and 21.6% of the New Zealand moss flora. This correlation is interpreted in terms of long distance dispersal resp. the common phytogeographical background of both countries as parts of the palaoaustral floristic region and compared with disjunct moss floras of other continents as well as the presently available molecular data
Preliminary classification and evaluation of Engelmann spruce
No full textThis thesis is divided in to two parts:
In the first part - A Preliminary Classification of the Engelmann
Spruce - Alpine Fir Forests at Bolean Lake, B. C. - some ecological concept
are discussed. The forest association is defined as an ecological unit
that includes the characteristics of climate, soil, topography, flora and
fauna; and is recognized by its floristic structure. The area studied is
described. Data were collected from selected temporary plot. Soil profile
was described and samples collected. Forest mensurational data were
collected on tenth-acre plots. Two forest associations can be considered
established. They are:
1. Picea Engelmannii - Abies Lasiocarpa - Vaccinium membranaceum -
Rubus pedatus association. (Engelmann spruce - alpine fir - black
huckleberry - trailing Rubus association). Designated the VM
association.
2. Picea Engelmannii - Abies lasiocarpa - Vaccinium membranaceum -
Dryopteris Linnaeana association, (Engelmann spruce - alpine fir -
tall blueberry - oak fern association). Designated the VO association.
Four other forest associations were tentatively identified. They are
described because they are of interest to foresters.
In the second part - An Evaluation of Two Forest Associations in
the Engelmann Spruce - Alpine Fir Forests at Bolean Lake, B.C. - forest
mensurational data from the vegetational plots were compared and analysed
with data from permanent sample plots established independently.
Differences in average height of dominant and codominant trees, in height
of average dominant tree, and in volumes between the VO and VM associations were found. These results indicate that the VO forest
association has better site quality than the VM forest association.
Differences were also found to composition, number of trees per acre
and in the distribution of stem size, these differences indicate
that the VO and VM associations will probably give different responses
to silvicultural treatment.Forestry, Faculty ofGraduat
Defining indigenous plants: some problematic species from Norfolk Island
No full textDefining indigenous species may at first appear straight forward; most botanical texts provide similar definitions. The consistent requirement of such definitions is the lack of human intervention in the occurrence of the species within the area under consideration. Islands around the world have been invaded by plant species brought to their shores by humans. They are also places where self-introduced species can be continually arriving, as they have done for millennia. Scrutiny of the situation on Norfolk Island (1200 km east of Australia) finds that the distinction between indigenous and introduced taxa is sometimes unclear. There is also inconsistency regarding the acceptance of self-introduced species as indigenous. This paper explores these issues and notes that they are more important than idle botanical curiosity, because control of introduced (weed) species is a major area of activity in managing protected natural areas
