Ilex perado populations are grouped obeying to the island of origin and not by the taxonomic classification. Fig. 1 Origin of the samples Objectives Our main goal is to investigate the lever of genetic diversity of Ilex perado ssp. lopezlilloi and their congeners of Macaronesia. Materials and Methods Sampling Leaf tissue samples of 242 individuals [I. perado ssp. lopezlilloi (5), I. perado ssp. platyphylla (93), I. azorica (20) and I. canariensis (124)] were analyzed (Table 1). Microsatellites The genetic analyses used primers developed to Ilex leucoclada (Torimaru et al., 2004). DNA extraction following the Doyle and Doyle (1987) protocol and subsequent purification with Gene Elute PCR Clean-Up Kit. Loads to amplifications included 20 ng of DNA. 10 pmol of each primer and 24 μl of PCR Master Mix solution (Reddy-Mix. ABgene. Surrey. UK). Amplification protocol: 3' at 94 °C; 30 cycles 45" at 94 °C. 45" at 56 °C and 45" at 72 °C; and 5' 72 °C. Amplification products were detected using an ABI 3130 XL genetic analyzer and size of the fragments was determined using GenScan 2.02 and GenoTyper 1.1 programs (Applied Biosystems. Inc.). Data Analysis All genetic diversity parameters (A, Ho, He and P), identity and genetic distance of Nei (Nei, 1973) were calculated using PopGene 3.2 (Yeh et al., 1997); Population 1.2.30beta (Langella, 2005) was used to construct a UPGMA dendrogram that displayed in Mega4 (Kumar et al., 2001); Structure 2.2 (Falush et al., 2007) was used to infer the populations structures through an implemented Bayesian analysis and GenAlEx 6.3 (Peakall and Smouse, 2006) for the principal coordinates analysis (PCoA).

Biodiversity Data Journal 9: e69924. https://doi.org/10.3897/BDJ.9.e69924 Abstract Background Long-term monitoring of invertebrate communities is needed to understand the impact of key biodiversity erosion drivers (e.g. habitat fragmentation and degradation, invasive species, pollution, climatic changes) on the biodiversity of these high diverse organisms. The data we present are part of the long-term project SLAM (Long Term Ecological Study of the Impacts of Climate Change in the natural forest of Azores) that started in 2012, aiming to understand the impact of biodiversity erosion drivers on Azorean native forests (Azores, Macaronesia, Portugal). In this contribution, the design of the project, its objectives and the first available data for the spider fauna of two Islands (Pico and Terceira) are described.

  • Gradient Analysis of Exotic Species in Pinus Radiata Stands of Tenerife (Canary Islands) S
    The Open Forest Science Journal, 2009, 2, 63-69 63 Open Access Gradient Analysis of Exotic Species in Pinus radiata Stands of Tenerife (Canary Islands) S. Fernández-Lugo and J.R. Arévalo* Departamento de Ecología, Facultad de Biología, Universidad de La Laguna, La Laguna 38206, Spain Abstract: Identifying the factors that influence the spread of exotic species is essential for evaluating the present and future extent of plant invasions and for the development of eradication programs. We randomly established a network of 250 plots on an exotic Pinus radiata D. Don plantation on Tenerife Island in order to determine if roads and urban centers are favouring the spread of exotic plant species into the forest. We identified four distinct vegetation groups in the P. radiata stands: advanced laurel forest (ALF), undeveloped laurel forest (ULF), ruderal (RU), and Canarian pine stand (CPS). The groups farthest from roads and urban nuclei (ALF and CPS) have the best conserved vegetation, characterizing by the main species of the potential vegetation of the area and almost no exotic and ruderal species. On the other hand, the groups nearest to human infrastructures (ULF and RU) are characterized by species from potential vegetation’s substitution stages and a higher proportion of exotic and ruderal species. The results indicate distance to roads and urban areas are disturbance factors favouring the presence of exotic and ruderal species into the P. radiata plantation. We propose the eradication of some dangerous exotic species, monitoring of the study area in order to detect any intrusion of alien species in the best conserved areas and implementation of management activities to reduce the perturbation of the ULF and RU areas.

Key to symbols and colored text: Checkboxes indicate species and/or cultivars that I want. Checkmarks indicate those that I have (or that one of my neighbors has). Text in blue indicates shrub or hedge. (Unfinished task – there is no text in blue other than this text right here.) Text in red indicates that the species or cultivar is undesirable: • Out of range climatically (either wrong zone, or won’t do well because of differences in moisture or seasons, even though it is in the “right” zone). • Will grow too tall or wide and simply won’t fit well on my property.

  • Page 1 the Following Pages Outline Phasing Recommendations for The
    Kruckeberg Botanic Garden Master Site Plan PHASING AND IMPLEMENTATION he following pages outline phasing recommendations for the KruckebergT Botanic Garden that seem desirable to address the needs, vision, and requirements of a private garden’s evolution into the publc domain. With the transfer of this property from a private residence to a commercial public entity, new sets of codes, restrictions, and opportunities come into play. These deal with public safety, health, and well-being and ensure that equal opportunities are afforded to all. Within a limited budget, Phase 1 responds to these immediate needs by providing on-site public parking to reduce impacts to the surrounding residential community, adding much needed public restrooms, and creating a permanent and separate service access road and staff parking area. Phase 2 focuses on siting an interpretive switchback boardwalk trail that connects the upper and lower gardens in an aesthetic ADA-compliant manner. It is also envi- sioned that an ADA-compliant loop path would be routed through the lower garden. While it would be optimal to build the environmental learning center in Phase 2, it is recognized that lack of funding may require deferment to a later phase. Further development of future phases depends on many factors, most importantly securing funding and the commitment of the City, Foundation, and public to sup- port and encourage new work to proceed. In the end, this alone will determine how quickly Garden projects are completed and the Garden vision, as outlined in this report, is realized. This is a modest plan as represented by the development costs associated with each phase in 2010 dollars.

Garajonay National Park in La Gomera (Canary Islands) contains one of the largest remnant areas of a forest formation once widespread throughout Europe and North Africa. Here, we aim to address the long-term dynamics (the last 9600 cal. years) of the monteverde forest (laurel forest and Morella-Erica heath) located close to the summit of the National Park (1487 m a.s.l.) and determine past environmental and human impacts. 2. We used palaeoecological (fossil pollen, microscopic and macroscopic charcoal) and multivariate ecological techniques to identify compositional change in the monteverde forest in relation to poten- tial climatic and human influences, based on the analysis of a core site at 1250-m elevation. 3. The regional mid-Holocene change towards drier conditions was matched in this system by a fairly rapid shift in representation of key forest elements, with declines in Canarian palm tree (Phoenix canariensis), Canarian willow (Salix canariensis) and certain laurel forest taxa and an increase in representation of the Morella–Erica woody heath.

Review and Propagation of the Holly Slope Abstract The purpose of this project was to complete several goals that contribute to a long-term ongoing renovation of the Holly Slope section at the Morris Arboretum. The first of these goals was to perform an assessment to determine if any of the hollies on the slope are rare or unique. This goal was completed by contacting nine other major holly collections to provide lists of their plants. Following the assessment, the next goal was to propagate those hollies with the eventual intention of offering specimens to other gardens and arboreta. The results of this work will contribute directly to future goals for the slope, including determining which holly plants can be removed to reduce crowding in order to revitalize the collection and opening up some areas to interplant the hollies with live oaks (Quercus virginiana). In addition to the previously mentioned efforts, this paper will explore a brief history of hollies and provide some general information on the taxonomy and botanical description of the holly genus, Ilex.

Abstract The taxonomic status of the Azorean endemic Viburnum tinus subsp. subcordatum is reassessed, using morphological characters and new molecular data from the ITS region and the trnK intron. A survey of morphological variation supports the recognition of V. tinus subsp. subcordatum as distinct from V. tinus subsp. tinus and the Canary endemic V. rugosum (formerly known as V. tinus subsp. rigidum) based on leaf shape, the shape of the leaf base and apex, the sub-entire and revolute leaf margins, blistered upper leaf surfaces, trichome density and type, and fruit size. Molecular data also confirm this distinctiveness within section Tinus.

  • Integration of Exotic Seeds Into an Azorean Seed Dispersal Network
    Biol Invasions DOI 10.1007/s10530-012-0357-z ORIGINAL PAPER Integration of exotic seeds into an Azorean seed dispersal network Ruben H. Heleno • Jaime A.

Exotic seeds deeply infiltrated into the seed ecology. Among animals, birds are particularly impor- dispersal network forming the majority (59 %) of seeds tant seed dispersers, often incorporating exotic plants in the droppings and including those of three globally into their diets and facilitating their integration in the invasive plants. Overall, birds depended equally on communities. Network theory offers a highly informa- native and exotic fruits despite the lower abundance of tive framework to study the structural and functional the latter in the study area. In an experiment, birds did attributes of complex interactions networks. We used not show a preference for fruits of the exotic Leycesteria information from bird fecal samples to build a quanti- formosa over the native Vaccinium cylindraceum con- tative seed dispersal network for the last fragment of suming them equally. However, the presence of the native laurel forest in the island of Sa˜o Miguel—Azores exotic plant negatively affected the number of native with three specific objectives: (1) to assess the integra- seeds dispersed, by diverting some of the consumers of tion of exotic seeds into seed dispersal; (2) to evaluate the native fruits. Taken altogether the results reveal an the impact of exotic plants in network structure; (3) to alarming invasion level of seed dispersal systems in one test the potential of an exotic species to reduce the seed of the last remnant native forests of the Azores.
