Other typically herbaceous dicotyledonous groups in which species of the Atlantic Islands are appreciably woodier than non-insular ones include Centaurea and Sonchus ( Asteraceae); Cheiranthus, Crambe, Descurainia, Parolinia, and Sinapodendron ( Brassicaceae); Convolvulus ( Convolvulaceae); and Plan tago ( Plantaginaceae). The tendency for Macaronesian species to be woodier than their main land relatives has naturally given rise to interpretations. The rosette shrubs of these islands are quite characteristic; such shrubs were termed "Feder buschgewachse" by Schenck ( 1907). These suggest to some workers her baceous groups in which the notably moderate climate of islands has per mitted continued growth; in these groups there is natural selection for plants that are of longer duration and increased woodiness, suiting the year-long growing season of such insular areas. -
The Canary Islands
The Canary Islands Dragon Trees & Blue Chaffinches A Greentours Tour Report 7th – 16th February 2014 Leader Başak Gardner Day 1 07.02.2014 To El Patio via Guia de Isora I met the half of the group at the airport just before midday and headed towards El Guincho where our lovely hotel located. We took the semi coastal road up seeing the xerophytic scrub gradually changing to thermophile woodland and then turned towards El Teide mountain into evergreen tree zone where the main tree was Pinus canariensis. Finally found a suitable place to stop and then walked into forest to see our rare orchid, Himantoglossum metlesicsiana. There it was standing on its own in perfect condition. We took as many pics as possible and had our picnic there as well. We returned to the main road and not long after we stopped by the road side spotting several flowering Aeonium holochrysum. It was a very good stop to have a feeling of typical Canary Islands flora. We encountered plants like Euphorbia broussonetii and canariensis, Kleinia neriifolia, Argyranthemum gracile, Aeonium urbicum, Lavandula canariensis, Sonchus canariensis, Rumex lunaria and Rubia fruticosa. Driving through the windy roads we finally came to Icod De Los Vinos to see the oldest Dragon Tree. They made a little garden of native plants with some labels on and the huge old Dragon Tree in the middle. After spending some time looking at the plants that we will see in natural habitats in the following days we drove to our hotel only five minutes away. The hotel has an impressive drive that you can see the huge area of banana plantations around it. -
Exotic Species and Temporal Variation in Hawaiian Floral Visitation Networks
Exotic Species and Temporal Variation in Hawaiian Floral Visitation Networks By Jennifer Lynn Imamura A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Environmental Science, Policy, and Management in the Graduate Division of the University of California, Berkeley Committee in charge: Professor George Roderick, Chair Professor Claire Kremen Professor Bruce Baldwin Spring 2019 Abstract Exotic Species and Temporal Variation in Hawaiian Floral Visitation Networks by Jennifer Lynn Imamura Doctor of Philosophy in Environmental Science, Policy, and Management University of California, Berkeley Professor George Roderick, Chair Many studies have documented the negative impact of invasive species on populations, communities, and ecosystems, although most have focused solely on antagonistic rather than mutualistic interactions. For mutualistic interactions, such as pollination, a key to understanding their impacts is how invasive species interact with native species and alter interaction networks. Chapter 1 explores the impacts of invasive species on islands, particularly in regard to plants, pollinators, and how these exotic species attach to existing pollination interaction networks. Island pollination networks differ from mainland counterparts in several important characteristics, including fewer species, more connectance, and increased vulnerability to both invasion and extinction. A progression of invasion has been previously proposed, through which supergeneralist native species -
Impact of Introduced Honey Bees on Native Pollination Interactions of the Endemic Echium Wildpretii (Boraginaceae) on Tenerife, Canary Islands
Impact of introduced honey bees on native pollination interactions of the endemic Echium wildpretii (Boraginaceae) on Tenerife, Canary Islands Yoko L. Dupont *, Dennis M. Hansen, Alfredo Valido, Jens M. Olesen Department of Ecology and Genetics, University of Aarhus, Ny Munkegade Building 540, Aarhus C 8000, Denmark Abstract The aim of this study was to investigate effects of introduced honey bees (Apis mellifera) on native pollination interactions of Echium wildpretii ssp. wildpretii in the sub-alpine desert of Tenerife. We selected two study populations, one dominated by honey bees, while the other was visited by many native insects. During peak activity period of insects, nectar was nearly completely de- pleted in flowers of the first, but not the latter population. Thus, a high abundance of honey bees may have suppressed visitation by native animals due to exploitative competition. Honey bees stayed longer and visited more flowers on the same inflorescence than native bees, thus potentially promoting self-pollination of the plants. Level of seed set and viability was similar in the two study populations. However, we cannot rule out long-term changes in genetic population structure due to changes in gene-flow patterns caused by foraging behaviour of honey bees vs. native flower-visitors. Keywords: Disruption of native mutualisms; Interspecific competition; Apis mellifera; Conservation 1. Introduction are often found to be less efficient pollinators compared to native flower-visiting animals (Schaffer et al., 1983; In recent years the impact of introduced honey bees Taylor and Whelan, 1988; Westerkamp, 1991; Paton, (Apis mellifera L.) on native flora and fauna has been 1993; Vaughton, 1996; Gross and Mackay, 1998; Han- much debated. -

This is probably the most well known location on Tenerife as it is where most people see their first Blue Chaffinches and we were not to be disappointed. Also at this location we saw the only Great Spotted Woodpecker of the tour plus a few Canaries, a Tenerife Kinglet and a few African Blue Tits. After departing from Las Lajas we continued climbing and entered the Las Cañadas National Park which is a spectacular drive through volcanic scenery. On the drive we encountered quite a few endemic plants including Pinus canariensis and Spartocytisus supranubius that were common and easily recognized and Echium wildpretii, Pterocephalus lasiospermus, Descurainia bourgaeana and Argyranthemum teneriffae which were rather unimpressive as they were not yet flowering but we were compensated by the fabulous views across the ancient caldera. -

Laurisilva of Madeira Portugal
LAURISILVA OF MADEIRA PORTUGAL The Laurisilva of Madeira is the largest surviving relict of a virtually extinct laurel forest type once widespread in Europe. It is still 90% primary forest and is a centre of plant diversity, containing a unique suite of rare and relict plants and animals, especially endemic bryophytes, ferns, vascular plants, animals such as the Madeiran long-toed pigeon and a very rich invertebrate fauna. COUNTRY Portugal NAME Laurisilva of Madeira NATURAL WORLD HERITAGE SITE 1999: Inscribed on the World Heritage List under Natural Criteria ix and x. STATEMENT OF OUTSTANDING UNIVERSAL VALUE The UNESCO World Heritage Committee adopted the following Statement of Outstanding Universal Value at the time of inscription: Brief Synthesis The Laurisilva of Madeira, within the Parque Natural da Madeira (Madeira Natural Park) conserves the largest surviving area of primary laurel forest or "laurisilva", a vegetation type that is now confined to the Azores, Madeira and the Canary Islands. These forests display a wealth of ecological niches, intact ecosystem processes, and play a predominant role in maintaining the hydrological balance on the Island of Madeira. The property has great importance for biodiversity conservation with at least 76 vascular plant species endemic to Madeira occurring in the property, together with a high number of endemic invertebrates and two endemic birds including the emblematic Madeiran Laurel Pigeon. Criterion (ix): The Laurisilva of Madeira is an outstanding relict of a previously widespread laurel forest type, which covered much of Southern Europe 15-40 million years ago. The forest of the property completely covers a series of very steep, V-shaped valleys leading from the plateau and east-west ridge in the centre of the island to the north coast. -

Cold Hardiness of Climatic Zone 9 Plants at 53' North Latitude David Robinson, Ph
ISSUE 70 SESGNO!.IA Cold Hardiness of Climatic Zone 9 Plants at 53' North Latitude David Robinson, Ph. D. This article is based on a talk Dr. Robinson gave at the Annual Meeting of the Magnolia Society in Ireland, March zoot. Although my garden at Earlsdiffe, Baily, Co Dublin is situated at 53' 3' north latitude, it has a favorable microdimate and contains many cimatic zone 9 (USDA) plants. The harsh 2000/2001 winter, the most severe since I started taking records in 1969, provided a good opportu- nity to record the effect of low temperatures on many marginally hardy plants. The 2000/01 Winter Autumn 2000 was mild and wet with temperatures well above average in early December. However, on the night of December 26/27, 2000, the air temperature fell to —6 'C (21.2 'F) and to -4 'C (24.8 'F), -7 'C (19.4 'F), -5.5 'C (22. 1 'F) and -4.5 'C (23.9 'F) on the following four nights. For the three days between the 28s and 30" of December the tempera- ture never rose above -3 or -4 'C (26.5 or 25 'F) during the day. At the end of the cold speB (December 30+), the temperature rose 7.5 'C (13 'F) during the night and was 3 'C (37 'F) by morning, so the speed of thaw was rapid. After a relatively mild January, another cold spell began on February 23/24, 2001 and the minimum air temperatures recorded on this, and the following nine days, were: -2 'C (28.4 'F), -2 'C (28,4 F'), —1.
