The Tropics

The tropics hold at least an order of magnitude greater plant diversity than the temperate zone, yet the reasons for this difference are still subject to debate. Much of tropical plant diversity is in highly speciose genera and understanding the drivers of such high species richness will help solve the tropical diversity enigma. Hybridization has recently been shown to underlie many adaptive radiations, but its role in the evolution of speciose tropical plant genera has received little attention. Here, we address this topic in the hyperdiverse Bromeliaceae genus Vriesea using genome skimming data covering the three genomic compartments. We find evidence for hybridization in ca. 11% of the species in our dataset, both within the genus and between Vriesea and other genera, which is commensurate with hybridization underlying the hyperdiversity of Vriesea, and potentially other genera in Tillandsioideae. While additional genomic research will be needed to further clarify the contribution of hybridization to the rapid diversification of Vriesea, our study provides an important first data point suggesting its importance to the evolution of tropical plant diversity.

Floral Diversity

Panchase Protected Forest (PPF), situated at the junction of three districts Kaski, Syangjaand Parbat with an elevation range of 900-2517m representing mid hills of Nepal. This study was carried out with an aim of documenting the flowering plant diversity of the Panchase Protected Forest, Kaski district, comprising three VDCs, Bhadaure Tamage, Chapakot and Pumdi Bhumdi. General survey, covering all seasons was organized (from June 2014 to May2015) for collecting the plant species. Published literatures and herbarium specimens were also consulted for documenting the species. Identification of the collected specimens was made through consulting relevant literatures, herbarium specimens and expert consultation. A total of 613 species belonging to 393 genera and 111 families have been documented from this area. The dominant family was Orchidaceae (49 genera and 125 species) followed by Poaceae (25 spp.), Asteraceae (25 spp.) and others. Six endemic plants, Begonia flagellaris (Begoniaceae), Eria pokharensis, Gastrochilus nepalensis, Oberonia nepalensis, Odontochilusnandae and Panisea panchaseensis (Orchidaceae) were also reported. Similarly, presentresearch revealed two taxa as new record for flora of Nepal, Dischidia bengalensis Colebr. (Apocynaceae) and Phreatia elegans Lindl. (Orchidaceae). The present findings suggest that PPF is one of the hotspot for floral diversity representing mid hills of Nepal and this pristine habitat for orchid should be developed as ‘Orchid Sanctuary’.

Annotated Catalogue

A catalogue of the flowering plants of the islands of São Tomé and Príncipe (Gulf of Guinea) is presented. Flowering plant diversity figures are updated to: 135 families (20 introduced), 624 genera (172 introduced), 1 104 species (301 introduced) plus 15 additional infraspecific taxa. At present 119 taxa (107 species and 12 infraspecific taxa) are known to be endemic to the two islands. The catalogue includes accepted names, synonyms used in recent literature, common names, voucher specimens and information on habit and habitat and on plant uses, particularly medicinally.

Plot Design

The botanical composition of grasslands determines the agronomic and natural values of swards. Good grassland management usually improves herbage value, but on the other hand it frequently decreases the plant diversity and species richness in the swards. In 1999 a field trial in a split-plot design with four replicates was therefore established on the Arrhenatherion type of vegetation in Ljubljana marsh meadows in order to investigate this relationship. Cutting regimes (2 cuts — with normal and delayed first cut, 3 cuts and 4 cuts per year) were allocated to the main plots and fertiliser treatments (zero fertiliser — control, PK and NPK with 2 or 3 N rates) were allocated to the sub-plots. The results at the 1 st cutting in the 5 th trial year were as follows: Fertilising either with PK or NPK had no significant negative effect on plant diversity in any of the cutting regimes. In most treatments the plant number even increased slightly compared to the control. On average, 20 species were listed on both unfertilised and fertilised swards. At this low to moderate level of exploitation intensity, the increased number of cuts had no significant negative effect on plant diversity either (19 species at 2 cuts vs. 20 species at 3 or 4 cuts). PK fertilisation increased the proportion of legumes in the herbage in the case of 2 or 3 cuts. The proportion of grasses in the herbage increased in all the fertilisation treatments with an increased numbers of cuts. Fertiliser treatment considerably reduced the proportion of marsh horsetail ( Equisetum palustre ) in the herbage of the meadows. This effect was even more pronounced at higher cut numbers. The proportion of Equisetum palustre in the herbage was the highest in the unfertilised sward with 2 cuts (26.4 %) and the lowest in the NPK-fertilised sward with 4 cuts (1.4%).
