“…New Zealand conifers are generally regarded as being tolerant of poor soils (Coomes and Bellingham, 2011;de Jonge et al, 2012), and have an affinity for leached, low nutrient, acid or poorly drained soils that form in ever-wet environments and some (Dacrydium cupressinum, Dacrycarpus dacrydioides, Lepidothamnus intermedius, Manoao colensoi, Libocedrus plumosa, Halocarpus bidwillii, H. biformis) are characteristic of such sites (Richardson et al, 2005b). Where the climate supports tall trees, conifers usually dominate the tree biomass as there are only three tall angiosperm trees that tolerate wetlands (Elaeocarpus hookerianus, Laurelia novaezelandiae and Syzygium maire; McGlone, 2009).…”

“…Pollen diagrams confirm this and peat sites usually show conifer sequences with Dacrycarpus dacrydiodes at the fertile, often swamp or lagoon beginning of the sequence, and Dacrydium cupressinum, Manaoa colensoi, Lepidothamnus intermedius, and Halocarpus bidwillii at the infertile bog later stages (McGlone, 2009). However, in some situations conifers are quick to colonize fertile soils after disturbance, losing ground to angiosperm broadleaves as the succession proceeds, and this is most apparent in the pollen record after large-scale volcanic disturbance (Wilmshurst and McGlone, 1996;Horrocks and Ogden, 1998) but it also occurs after smaller scale disturbances (Bray, 1989;Carswell et al, 2007;de Jonge et al, 2012).…”

The New Zealand conifers (20 species of trees and shrubs in the Araucariaceae, Podocarpaceae, and Cupressaceae) are often regarded as ancient Gondwanan elements, but mostly originated much later. Often thought of as tall trees of humid, warm forests, they are present throughout in alpine shrublands, tree lines, bogs, swamps, and in dry, frost-prone regions. The tall conifers rarely form purely coniferous forest and mostly occur as an emergent stratum above evergreen angiosperm trees. During Maori settlement in the thirteenth century, fire-sensitive trees succumbed rapidly, most of the drier forests being lost. As these were also the more conifer-rich forests, ecological research has been skewed toward conifer dynamics of forests wetter and cooler than the pre-human norm. Conifers are well represented in the pollen record and we here we review their late Quaternary history in the light of what is known about their current ecology with the intention of countering this bias. During glacial episodes, all trees were scarce south of c. 40 • S, and extensive conifer-dominant forest was confined to the northern third of the North Island. Drought-and cold-resistant Halocarpus bidwillii and Phyllocladus alpinus formed widespread scrub in the south. During the deglacial, beginning 18,000 years ago, tall conifers underwent explosive spread to dominate the forest biomass throughout. Conifer dominance lessened in favor of angiosperms in the wetter western lowland forests over the Holocene but the dryland eastern forests persisted largely unchanged until settlement. Mid to late Holocene climate change favored the more rapidly growing Nothofagaceae which replaced the previous conifer-angiosperm low forest or shrubland in tree line ecotones and montane areas. The key to this dynamic conifer history appears to be their bimodal ability to withstand stress, and dominate on poor soils and in cool, dry regions but, in wetter, warmer locations, to slowly grow thorough competing broadleaves to occupy an exposed, emergent stratum where their inherent stress resistance ensures little effective angiosperm competition.

“…and ecological importance. Recently, various contributions (e.g., Chernetsky et al 2010;de Jonge et al 2012; have indicated that tidal characteristics can change significantly due to anthropogenic measures. These changes can endanger safety, i.e., changes in the surface elevation may cause flooding in the surrounding area, and transport (related to the changes in the three-dimensional velocity field) or accumulation of sediments and pollutants which leads to poor quality of water.…”

Three-dimensional semi-idealized model for tidal motion in tidal estuaries

et al. 2015

In this paper, a three-dimensional semi-idealized model for tidal motion in a tidal estuary of arbitrary shape and bathymetry is presented. This model aims at bridging the gap between idealized and complex models. The vertical profiles of the velocities are obtained analytically in terms of the first-order and the second-order partial derivatives of surface elevation, which itself follows from an elliptic partial differential equation. The surface elevation is computed numerically using the finite element method and its partial derivatives are obtained using various methods. The newly developed semi-idealized model allows for a systematic investigation of the influence of geometry and bathymetry on the tidal motion which was not possible in previously developed idealized models. The new model also retains the flexibility and computational efficiency of previous idealized models, essential for sensitivity analysis. As a first step, the accuracy of the semi-idealized model is investigated. To this end, an extensive comparison is made between the model results of the semi-idealized model and two other idealized models: a width-averaged model and a three-dimensional idealized model. Finally, the This article is part of the Topical Collection on Physics of Estuaries and Coastal Seas 2014 in Porto de Galinhas, PE, Brazil, 19-23 October 2014

“…Sustainable development is a complex issue, involving strongly interconnected ecological, social, and economic aspects of an ecosystem, now and in the future (de Jonge et al 2012). In fact, according to Kiker et al (2005), 'Decision-making in environmental projects can be complex and seemingly intractable, principally because of the inherent trade-offs between socio-political, environmental, ecological, and economic factors'.…”

“…Multi-criteria analyses (MCA) have been recommended as useful tools to ensure an integrated management of an ecosystem, allowing the incorporation of different sets of data (e.g., Villa et al 2002;Pavlikakis and Tsihrintzis 2003;de Jonge et al 2012). MCA is a stepwise process that allows the comparing of decision alternatives with multiple and often complex impacts (Hermann et al 2007).…”

Mainstreaming Sustainable Decision-making for Ecosystems: Integrating Ecological and Socio-economic Targets within a Decision Support System

Ecosystem sustainable management, and the underlying decision-making process, generally requires the analysis of ecological, social and economic information, integrating both value judgements and policy goals. Since this process can be regarded as complex and tricky, natural resource management requires a well-structured and transparent decision-making process. In this regard, it is necessary to search for and implement sets of measures which can effectively solve emerging problems. Based on the assumption that decisions concerning the management of watersheds may imply trade-offs between their different functions, the intent was to test if software tools, such as MULINO, could be used to enhance multi-level governance of ecosystems. To achieve this, the DPSIR and MCA were incorporated, to analyze and quantify the explicit trade-offs between several types of services provided by estuarine ecosystems and stakeholder objectives. The Mondego Estuary (Portugal) was used as case study. This system is under constant pressure, from both natural and anthropogenic drivers. Urban expansion and tourism were identified as having a strong impact on system development, while agriculture, although declining, had a determinant role in the system's status. The study evaluated potential alternatives focusing on the water quality improvement goals that could be designed for the system. The MCA ranked several alternatives and pinpointed as the best option the alternative that combines buffer zones, eco-tourism enhancement, wastewater treatment plant development, the Murraceira trademark and bivalves bio-control.
