The alpine flora on inselberg summits in the Maloti–Drakensberg Park, KwaZulu-Natal, South Africa

Background: Inselberg summits adjacent to the Maloti–Drakensberg escarpment occupy an alpine zone within the Drakensberg Alpine Centre (DAC). Inselbergs, the escarpment and surrounding mountains such as Platberg experience a severe climate; inselberg summits are distinct by being protected from human disturbance.Objectives: The aim of this article was to describe for the first time the flora of inselberg summits and to assess their potential contribution to conservation of DAC plant diversity.Method: We investigated whether the flora of inselberg summits formed a representative subset of the DAC flora in terms of shared, especially endemic or near endemic, species and representation of families. All species were listed for six inselbergs between Giant’s Castle and Sentinel, located in the Royal Natal National Park (RNNP) during November 2005. Comparisons, using literature, were made with floras of the DAC, as well as Platberg, an inselberg approximately 60 km north from Sentinel in the RNNP.Results: We recorded 200 species of pteridophytes and angiosperms on inselbergs, 114 DAC endemics or near endemics, one possible new species, and several range and altitudinal extensions. Asteraceae, Poaceae and Ericaceae comprised 42.1% of endemic and near endemic species, with Scrophulariaceae and Hyacinthaceae contributing 8.8%. Inselberg and DAC floras differed in respective rankings of Crassulaceae (8th vs. 15th), Polygalaceae, Apiaceae and Rosaceae (10th, 11th, 12th vs. 15th), Poaceae (2nd vs. 5th), Cyperaceae (3rd vs. 4th) and Scrophulariaceae (6th vs. 2nd). Growth forms on inselbergs were consistent with DAC flora. Inselbergs shared 40% of species with Platberg.Conclusion: Inselbergs, which supported 7.9% of species occurring in the DAC flora, are well protected from human impact, lack alien plants, but, despite this, are highly vulnerable to climate change. Conservation importance of inselbergs will increase as escarpment vegetation becomes increasingly degraded as a consequence of intensifying land use.

Nowe stanowisko Lycopodiella inundata (Lycopodiaceae) w Kotlinie Biskupiego Boru (Wyżyna Śląska)

Lycopodiella inundata is a rare and protected pteridophyte species in Poland. It usually occurs in oligotrophic wetlands, mainly in transitional moors (Rhynchosporetum albae). Lycopodiella inundata has rarely been found at natural sites recently, probably due to unfavorable environmental changes, but appears more and more often at sites created by human activity, such as sand pits, gravel pits and the banks of fish ponds. In 2014 a new site of L. inundata was found in the eastern part of the Szczakowa sand pit (19°25′35″E, 50°15′18″N). In this area, L. inundata grows well and occurs abundantly in small conspecific patches, aggregations, or as solitary plants. The main threats to this site are expansion of forest and shrub vegetation, reed expansion, changes in groundwater level, and drainage of the area.

Ferns and lycophytes from Serra dos Carajás, an Eastern Amazonian mountain range

Abstract In the state of Pará (Brazil), until the beginning of last decade little was known about the composition of the fern and lycophyte flora. The ferruginous mountains of Carajás are located in Southeastern Pará, mostly inserted in the Floresta Nacional de Carajás. The objective of this work is to present a complete and updated list of fern and lycophyte species occurring in all vegetation types from Carajás ferruginous mountains as a contribution to the knowledge of these plant groups from the Brazilian Amazon. The species list was based on specimens collected between 2007 and 2013. About 1068 specimens deposited in the BHCB Herbarium were studied. A total of 186 species of pteridophytes were recorded, 175 species of ferns distributed in 22 families and 68 genera, and 11 species of lycophytes distributed in three families and four genera. The fern and lycophyte flora of Serra dos Carajás region corresponds to 64% of the Pará state flora of these groups and 34% of the Brazilian Amazon fern and lycophyte flora. Seven taxa are presented as new records for Pará state: Asplenium abscissum, A. otites, A. praemorsum, Blechnum lanceola, Elaphoglossum minutum, Doryopteris collina, and Hemionitis tomentosa. Three species are endemic to Serra dos Carajás, Isoetes cangae, I. serracarajensis, and Selaginella stomatoloma.

Phytolith spectra of some eastern Himalayan pteridophytes: Assessing potential for distinguishing different vegetation–climate zones along the elevation gradient

To understand the relationship of phytolith production patterns in regional pteridophytes with elevation dependent climatic variables, and their potential to differentiate vegetation zones of the eastern Himalayan Mountain, we have studied phytolith spectra of 58 pteridophytic species of 22 families from tropical–temperate vegetation belts of Darjeeling, Sikkim and Arunachal Pradesh. Nineteen major phytolith types recovered from foliages and shoots of the pteridophytes are assessed for their potential to distinguish different vegetation zones, if any. Combined data suggest that epidermal polygonal (EP), jig saw plate (JSP), cast of epidermal cells (CEC), globular folded (GF), polyhedral bodies (PB), hair cell base (HCB) and silicified tracheids (TR) are the most significant phytolith morphotypes produced along the tropical‒temperate vegetation belts. Of these, CEC and GF could successfully discriminate tropical and sub-tropical from temperate vegetation. PB may be used as indicator of sub-tropical/lower-temperate vegetation and climate, and HCB as indicator of sub-tropical‒temperate vegetation and climate. Cluster analysis (CA) applied on the pteridophyte phytolith data shows morphotype signal for different vegetation zones. Discriminant analysis (DA), detrended correspondence analysis (DCA) and redundancy analysis (RDA) have arranged pteridophytic phytolith assemblages along the evapotranspiration and moisture availability gradients, approximating the actual distribution of vegetation along the rising elevation. DA has classified 75% of the taxa into their correct vegetation zones. Misclassification by DA may be attributed to the redundancy of the phytolith morphotypes among the studied taxa and indicating that caution should be taken when applying them in the fossil phytolith assemblages. The study infers a combined influence of climate–energy and moisture availability on the elevational distribution of the pteridophytic phytoliths in the eastern Himalaya. This study indicates that pteridophytic phytoliths have the potential to record regional forest zones despite steep environmental gradients and may be used in interpreting regional fossil pteridophytic phytolith spectra during palaeoclimate reconstructions.

Comparing Generalized Linear Model of Count Data: Application towards Pteridophyta species

Pteridophyta is known as “paku-pakis” in Malay and it is one the flora species that exists in ecological system. Besides, Pteridophyta is one of the species that need to be preserved. Either flora or fauna, both are very important to preserve the ecosystem and control the pollution. In order to observe the species, the fundamental unit of all diversity metrics is a count of specific individuals. In some consequences, the uncorrected counts of observed species often used in measuring the diversity which ignore detection together and established methods to be used to account for missed species. Analysis of count data is widely used in engineering, public health, epidemiology, medical studies, ecology and many research of interest. Rarity increases the number of locations with zero detection in excess of those expected under simple models of abundance. The aims of this study are to compare the Generalized Linear Model (GLiM) in the application of Pteridophyta species of count data.

Biodiversity of the vascular plants in the young fluvioglacial landscapes in the Severo-Chuiskiy centre of present-day glaciation (the Central Altai)

This article reports the species richness of vascular plants in the young fluvioglacial landscapes in the Severo-Chuiskiy centre of present-day glaciation using the example of the fluvioglacial deposits of the mountain-glacial basin Aktru. These landscapes are four well distinguished classes of habitats: open pebble fields with minimal vegetation, young larch forests on elevated parts of the relief, shrub thickets on the banks of the Aktru river, and sites with ground-frazil near the valley slopes. There are 132 species of vascular plants in the young fluvioglacial landscapes. These include 36 families and 77 genera. There are 3 species of pteridophytes (only Equisetum), 4 species of gymnosperms, and 125 species of angiosperms. The highest species diversity was recorded for Asteraceae, Poaceae and Salicaceae families, and for Salix, Poa, and Carex genera. The highest species richness – 100 species – were recorded for open pebble fields. There were 76 species in the young larch forests, and 58 species occurred in shrub thickets. The lowest richness is characterised for the sites with ground frazil, where 31 species were recorded.
