Abstract:
Yew (Taxus baccata L.) is one of the most important and threatened tree species in the Arasbaran region of northwestern Iran. To understand the natural stand structure of yew forests to inform forest management, we assessed the structural characteristics and composition of yew communities using the nearest neighbour and full callipering method at three sites with different conservation histories. Within a one-hectare sampling area, tree species identity, diameter, height, and crown diameter were measured. In each of these sampling areas, 56 sample points were surveyed in a 25 m × 25 m grid for

Yew <em>Taxus baccata</em> L. is an endangered tree species in parts of Europe. In Poland small populations grow in forest reserves. The study was conducted in two reserves established particularly for the protection of yew populations located in the regon of Pomerania. The aim of the study was to know the number, vitality and growth conditions of natural yew regeneration and to identify threats to the regeneration of the species. The stand structure and regeneration of yew was described in 30 circular plots. The main tree species in stand canopy was Scots pine, however in &lsquo;Bogdanieckie

Taxus baccata L. subsp. wallichiana (Zucc.) Pilger has come into prominence in recent times due to its uncontrolled harvesting from the Himalayan wilds for the extraction of the anti-cancer drug Taxol. It is a very slow growing tree with poor regeneration, and the extent of canopy damage is likely to have serious consequences on biomass yield, plant survival and natural regeneration by affecting 'seed' output. The present study in the Jageshwar area of the Central Himalaya aimed to determine the stand and canopy structure, microsite characteristics, extent of canopy removal, and regeneration i

Abstract:
Canada yew (Taxus canadensis Marsh.) is a gymnosperm that grows in the understory of mixed and deciduous forests of northeastern North America. This shrub had no economic importance until the discovery of paclitaxel, or TAXOL®, which is a compound found in plant tissue and used in cancer treatment. With the intensifying harvesting pressure on natural populations of this species, the natural gene pool might be affected. The objective of this study was to estimate the levels of genetic diversity and population structure in Canada yew, before any sizeable effects resulting from harvesting appear.

Pacific yew (Taxusbrevifolia Nutt.) is a shade-tolerant gymnosperm native to the western United States and Canada. It recently gained attention as the source of Taxol® (paclitaxel), a promising new anticancer drug. Large-scale harvest of mature Pacific yew trees for the extraction of paclitaxel has resulted in the need for improved forest management practices and an increased understanding of the amount and distribution of genetic variation in the species.

Abstract:
Abstract This paper presents an investigation of a newly discovered motion instability phenomenon for floating wind turbines. The instability is due to anti-symmetric coupling terms in roll and yaw caused by the turbine thrust force. For floaters with small separation between the uncoupled roll and yaw natural periods these coupling forces may result in rigid body roll and yaw oscillations. The paper explains the theory and the physics of the instability phenomenon, and analytical expressions for these stiffness coupling terms (K46 and K64) are derived. The instability phenomenon is demonstrat

Abstract:
The research focuses on vernacular architecture, in particular earth buildings, highlighting the different geographic areas involved, building types and construction techniques. In Italy, despite theoretical progress, some cultural and technical problems are still evident in earth architecture conservation. This is also due to the prevalence, among earth buildings, of vernacular architecture, that, in general, has no artistic value and with historical value yet to be fully appreciated. The characteristics of some regional areas are also considered, with particular attention to the Marche and S

Abstract:
Field measurements of the response of a number of drilling risers indicate that vortex-induced vibration (VIV) occurs significantly less often than predicted by the industry-standard fatigue analysis computer program SHEAR7 V4.4. Several comparisons to model tests and field data, including one published by BP and 2H in 2007 [1], demonstrate that this analysis program is generally quite conservative, given that VIV occurs. Furthermore, this conservatism does not take into account those situations in which VIV fatigue is predicted but none is observed in the field, which adds yet another layer o

Abstract:
Faced with growing environmental threats, governments and the international community have sought ways to halt biodiversity loss and ecosystem degradation and realize global climate and development priorities. Today, expanding the global network of protected areas is a key approach for achieving the goals of the Convention on Biological Diversity (CBD), the 2030 Agenda for Sustainable Development, and the Paris Agreement on climate change. But human pressure is increasing in and around protected areas, and far from improving the lives of those affected by the growing number of conservation ini

Abstract:
Once numbering in the tens of millions, plains bison (Bison bison bison) were nearly driven to extinction with only a few hundred individuals remaining by the late 19th century. Plains bison have since recovered to approximately 20,000 animals managed in conservation herds throughout North America, yet substantial challenges to their recovery remain. The Department of the Interior (DOI) is working with diverse partners to steward approximately 11,000 bison in 18 conservation herds across 12 states. Most herds exist in areas without native predators, and removals are required to keep herd sizes

The world is increasingly urbanized and yet, even in urban areas, humans remain dependent on the ecosystem services that nature provides. This case study-exercise explores selected aspects of the dynamic between humans and urban ecology in three parts. First, we briefly discuss urban ecosystems and the context of biodiversity conservation in urban areas. Then, through a case study of the Million Trees program in New York City, we provide evidence and start a discussion about the possible benefits—as well as potential negative social, ecological, and economic consequences—of urban trees.

Abstract:
The New Zealand public, its industries and the conservation sector, are greatly concerned about the state of national biosecurity protection, awareness and system performance – and rightly so. Scarcely a day goes by without a new story in the media about a biosecurity breach, a pest, a threat or a related impact on the economy, biodiversity, human health or lifestyles. The vast majority of this public focus is on issues at the national border. Yet the greatest number and cost of biosecurity programmes in New Zealand, and the greatest impact on citizens’ wallets, are the many pest management pr

Abstract:
Humans are dependent on resources and processes provided by ecosystems, known as ecosystem services (e.g., food, clean water, disease control, climate regulation). Yet populations are placing increasing demands on critical ecosystems, often leading to their degradation and loss. This unsustainable use can be partly attributed to the fact that ecosystem services are not fully captured in commercial markets and are thus undervalued. Payments for Ecosystem Services (PES) are a suite of mechanisms designed to determine the value of ecosystem services and promote their conservation in the marketpla
