Abstract:
A forest type dominated by Peltogyne gracilipes Ducke (Caesalpiniaceae) occurs on Maraca Island on a range of soil types. Maraca is located in Roraima State (Brazil) in the Rio Uraricoera and has an area of about 100,000 ha. This study compares the structure and floristic composition of the Peltogyne forest with the most widespread lowland forest type on Maraca and investigates some factors that could be involved in the persistent monodominance of Peltogyne. Three 0.25 ha plots were set up in each of three forest types: Peltogyne-rich forest (PRF), Peltogyne-poor forest (PPF) and forest withou

Abstract:
Intensive agricultural developments and increasing human population has caused severe lowland-forest loss and fragmentation in the western coastal plain in Taiwan over the past centuries. The goal of this study is to explore the multiscale impacts of forest fragmentation on species richness and community composition of lowland-forest birds in Taiwan. At a regional scale, Island Biogeography Theory was applied to examine area and isolation effects on species richness of lowland-forest birds using bird data derived from Breeding Bird Survey Taiwan in 2009 and 2010.

Extensive areas of Sitka spruce plantations established during the last 15 years on the CH-phase of the salal-moss ecosystem association on northern Vancouver Island are presently exhibiting symptoms of severe chlorosis and growth check.

Comparisons of the soil nutrient levels between this poorly productive CH-phase and the adjacent highly productive HA-phase were made.

Abstract:
In the past, forested areas have been used primarily for timber production. However, the recent growth of nature-based tourism has given monetary value to the recreation and scenic characteristics associated the forests in many places. This can lead to conflicts between forestry and tourism raising questions relating to the management of these two industries. What impact does forestry have on the perception of tourists in region’s that promote natural landscapes?

Hypothesized relationships between vegetation and environmental variation were examined using gradient analysis and multivariate methods. Successive reciprocal averaging ordination of the vegetation data led to the recognition of six vegetation groups (floodplain, subalpine, Pinus contorta, Pseudotsuga, Thuja, Abies)

Forests are major ecological structures of the terrestrial environment that enhance biodiversity through different kinds of specialized relations that exist between the vegetal canopy and organisms from all animal reigns. The concept of forest has recently been transplanted in the marine environment; marine forests share all ecological features of terrestrial forests. What is actually peculiar in the marine environment is the shift from the ‘vegetal’ forest in shallow depths (within the photic zone) to the ‘animal’ forest (dwelling in the circalittoral zone) throughout the depth gradient. ‘Ani

This increases frost severity and -due to the low frost tolerance of most woody New Zealand plant species - frosts are severe enough to prevent the establishment of most plant species which are common in the surrounding forest vegetation.

Abstract:
Using trap data the Hawdon, Poulter and South Branch valleys, a spatial distribution model was created for Stoats (Mustela erminea), Ship Rats (Rattus rattus) and Weasels (Mustela nivalis) in the North Branch of the Hurunui River. Ten spatial attributes were analysed in this thesis as potential spatial predictors of Stoats, Ship rats or Weasels; four of which were distance related measurements (distance from ecotonal edge, distance from river, distance from river tributary and distance from trapping edge); three were climate based variables (mean maximum temperature, mean minimum temperature a

Abstract:
The impacts of possum herbivory were assessed on 713 individual plants of the nationally endangered Pittosporum patulum and 115 individual plants of the threatened ('Gradual Decline') mistletoes (Alepis flavida & Peraxilla tetrapetala) over three years in the Temple and Huxley river valleys in the Ohau catchment, South Island New Zealand. Statistical models were used to test the influence of several explanatory variables on the probability of survival and growth rates of these rare palatable plants. Increasing defoliation levels were the most significant predictors of mortality for both P. pat

Abstract:
Poison operations are a widely used technique for rodent control in the indigenous forests of New Zealand. This study examined the bait-take and rat monitoring data obtained for continuous poison operations at Boundary Stream Mainland Island (BSMI), Hawke’s Bay, between 1996 and 2007. Since the beginning of the Mainland Island project at BSMI in 1996, 800 ha of indigenous forest have been treated with an ‘Integrated Pest Management’ approach, in which rodents (primarily ship rats) have been targeted by consecutive ground poison operations. The aim of the intensive pest control was to allow the

Abstract:
Spectacular fossil trees and shrubs are preserved within fossil soils in their original growth positions in mid Cretaceous rocks on Alexander Island, Antarctic Peninsula. These fossils indicate that diverse forest communities grew upon the floodplain areas of Alexander Island during the Albian at a palaeolatitude of 69-75 ° S. The fossil forests are preserved within the fluvial sediments of the Triton Point Formation of the Fossil Bluff Group, which represents the infill of a fore-arc basin. The fluvial environment matured from a braided river system, with frequent floods and unstable channel

Abstract:
This work traces the Maltese Islands' forest history. In prehistoric time the flora changed accordingly to climatic oscillations. The first people of Malta were Neolithic. Their forest clearance and the drying up of the climate led to population collapse. After a period of time, the forest may have recovered allowing colonisation by a Bronze Age people. The Classical Era where Malta's vegetation was changed and arable agriculture prevailed following this. Olive industry finds dating from the Roman period reveal that olive cultivation was widespread. The Arab period saw the depopulation of the
