Temporal Development and Regeneration Dynamics of Restored Urban Forests
Temporal Development and Regeneration Dynamics of Restored Urban Forests By Katherine de Silva A thesis submitted to the Victoria University of Wellington in fulfilment of the requirements for the degree of Masters in Ecology & Biodiversity School of Biological Sciences Faculty of Sciences Victoria University of Wellington October 2019 Supervisors: Stephen Hartley. Director of the Centre of Biodiversity & Restoration Ecology, Victoria University of Wellington Kiri Joy Wallace. Postdoctoral Fellow, Environmental Research Institute, University of Waikato. Katherine de Silva: Temporal Development and Regeneration Dynamics of Restored Urban Forests, © October 2019. 2 ABSTRACT Urban forest restoration programmes are a key tool used to initiate, re-create or accelerate the succession of forest species; improving ecosystem services, function, resilience and biodiversity. Succession is a temporal shift in species dominance driven by abiotic and biotic influences, but over decadal timescales the trajectory and success of restoration plantings in degraded urban environments can be hindered. To facilitate the successful reconstruction of forest ecosystems from scratch, an understanding of the temporal patterns in planted forest development, dynamics of seedling regeneration and dominant drivers of seedling diversity is required. Using a chronosequence approach, permanent plots were established at 44 restored urban forests aged 5 to 59 years since initial plantings took place, across five New Zealand cities between Wellington and Invercargill. Vegetation surveys were undertaken and data on micro- climate were collected. This study examined the 1) temporal dynamics of restored urban forest development and seedling regeneration and 2) dominant drivers of seedling regeneration. Data were analysed using linear regression models, breakpoint analysis and mixed-effects modelling. Early forest development (<20 years) exhibited the most changes in canopy composition and structure, forest floor dynamics, seedling community and microclimate. -

Acta Botanica Brasilica - 33(3): 412-424. July-September 2019. doi: 10.1590/0102-33062018abb0321 Spore diversity among species of Blechnaceae in the Atlantic Forest Dilma Melo da Silva1 , Lana da Silva Sylvestre2 , Cláudia Barbieri Ferreira Mendonça3 and Vania Gonçalves-Esteves3* Received: September 23, 2018 Accepted: March 8, 2019 . ABSTRACT The palynological diversity of Blechnaceae in the Atlantic Forest was investigated. While the monophyletic family belongs to the group of leptosporangiate ferns, a new classification proposed by recent phylogenetic study reorganizes the family and adds new genera. To expand palynological knowledge of the group, the spore morphology of 23 species and a hybrid, distributed among 10 genera, was described. Material from herbarium collections were submitted to acetolysis and mounted on slides, with subsequent statistical analysis of spore measurements. Photomicrographs of the material were taken under both light and scanning electron microscopy. Perine ornamentation varied among psilate, rugulate and scabrate; granules and gemmae were present along with thin, smooth cristae. Species of Blechnum and Austroblechnum exhibited the greatest diversity. The attributes of the spores obtained here were able to differentiate the analyzed species, although the spore morphology of some taxa was found to be very similar. Multivariate analysis assessed the relevance of quantitative data for differentiating the taxa.

BSO Feb 2017 Newsletter Final
Newsletter Number 80 February 2017 February 2017 BSO Newsletter 80 2 BSO Meetings and Field Trips Saturday 4th February 8.00 am Field Trip to Herbert Forest. One of the positive aspects to come out of plantation forestry has been the setting aside of areas of native vegetation that might otherwise have missed out on protection. Blakely Pacific’s forestry operations at Herbert encircle a number of such areas. Subject to forestry operations this field trip will take us into one of several examples of dry, coastal podocarp forest. Leaving early and returning late afternoon. Further details on our website nearer to the time. Contact John Steel 021 2133 170, email [email protected] Wed 22nd February 2017 5.20 pm Botanical gems of Stewart Island/Rakiura. Speaker: John Barkla, Department of Conservation. Over the past year John and Marilyn have undertaken a couple of long tramping trips through Stewart Island/Rakiura reacquainting themselves with the island’s amazing biodiversity they first experienced over 25 years ago. John will talk about the special plants and ecosystems for which Stewart Island/Rakiura is now the national stronghold. Wednesday 8th March 5.20 pm Breaking Down Decomposition: Using Teabags to Investigate Decomposition Rates along Aspect and Elevation Gradients. Speaker: Dr. Barbara J. Anderson, Ecologist and Research Scientist, Landcare Research. Barbara and her colleagues use the newly developed Tea Bag Index (TBI) to investigate the relative effects of microclimate on decomposition rate along aspect and elevation gradients on Mt. Cardrona, Central Otago, from 500m to 1936m. The Teabag Index exploits the difference in relative decomposability of Green Tea and Red Tea to construct a decomposition curve over a single three month time period. -

In their paper the authors adopted the broad ‘traditional, inclusive view’ of the Blechnaceae because this was ‘favoured by the senior author’ (see Chambers and Wilson 2019, p. 43). Chambers and Wilson (2019) did note however, that under the classication of Gasper et al. -

Carl J. Rothfels and Michael A. Sundue contributed equally to this work. Author for correspondence: Carl J. Rothfels, [email protected] Abstract We present a family-level classification for the eupolypod II clade of leptosporangiate ferns, one of the two major lineages within the Eupolypods, and one of the few parts of the fern tree of life where family-level relationships were not well understood at the time of publication of the 2006 fern classification by Smith & al. Comprising over 2500 species, the composition and particularly the relationships among the major clades of this group have historically been contentious and defied phylogenetic resolution until very recently. Our classification reflects the most current available data, largely derived from published molecular phylogenetic studies. -

Understanding the role and impact of introduced honey bees in a submontane indigenous forest ecosystem A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Biological Sciences at The University of Waikato by Rachel Elizabeth Nepia 2020 “Earth's crammed with heaven, And every common bush afire with God, But only he who sees takes off his shoes; The rest sit round and pluck blackberries.” -Elizabeth Barrett Browning- Abstract New Zealand’s apiculture industry is the fastest growing in the world, expanding in agricultural landscapes, as well as in native ecosystems. While this has obvious benefits for economy and industry, the impacts on sustainability of native ecosystems are less easy to discern. Honey bees (Apis mellifera) have a suite of potential impacts, both positive and negative, on native plants and flower visitors in native ecosystems.
