Nursery Practices

The implication of the nursery trade in the historic movement of the pathogen that causes kauri dieback (Phytophthora agathidicida) instigated a review of nursery biosecurity procedures at Auckland Botanic Gardens. The nursery grows 65 000 native plants a year which are planted at restoration sites throughout Auckland. Threatened plants are also grown in the nursery and returned to the wild. The nursery biosecurity  project resulted in a manual of protocols, supported by infrastructure upgrades, to ensure the nursery takes all practicable steps to ensure there is as little risk as possible to natural ecosystems through nursery practices. This work also demonstrates the important role of Botanic Gardens in providing education and advocacy for such schemes in all nurseries.

The aim of the article was to defi ne the role of the radioactive environment contamination in the formation of ecosystem services strategy. Methods. Monographic, systemic and structural, factor analysis, abstract and logical research methods have been used. The data from the State Statistics Service of Ukraine, the Ministry of Agrarian Policy and Food of Ukraine, the Ministry of Ecology and Natural Resources of Ukraine, materials of scientifi c researches, international materials and reports and other literary sources on the issues investigated have been used as an information base. Results. Retrospective analysis of sources and state of radioactive eco- systems contamination was conducted and the priority steps in developing the concept of ecosystem services in conditions of radiation contamination were found. Conclusions. The current socio-ecological paradigm of the transition from environmental use to environmental management should be refl ected in the relevant envi- ronmental management mechanisms. Currently, when assessing the state of ecosystem services in Ukraine and worldwide one must take into account the changes in food demand of residents of radioactively contaminated areas, the exploitation of radioactively safe ecosystems growth, their overload and degradation. All of this re- quires an inventory of ecosystem services by type, region, consumers, etc. and the formation of a state register of ecosystem services with a clear assignment of area of responsibility for appropriate natural ecosystems. This will help to make the economic evaluation of different ecosystem services and mechanisms of charges for ecosystem services.

In natural ecosystems, plants are constantly exposed to changes in their surroundings as they grow, caused by a lifestyle that requires them to live where their seeds fall. Thus, plants strive to adapt and respond to changes in their exposed environment that change every moment. Heat stress that naturally occurs when plants grow in the summer or a tropical area adversely affects plants’ growth and poses a risk to plant development. When plants are subjected to heat stress, they recognize heat stress and respond using highly complex intracellular signaling systems such as reactive oxygen species (ROS). ROS was previously considered a byproduct that impairs plant growth. However, in recent studies, ROS gained attention for its function as a signaling molecule when plants respond to environmental stresses such as heat stress. In particular, ROS, produced in response to heat stress in various plant cell compartments such as mitochondria and chloroplasts, plays a crucial role as a signaling molecule that promotes plant growth and triggers subsequent downstream reactions. Therefore, this review aims to address the latest research trends and understandings, focusing on the function and role of ROS in responding and adapting plants to heat stress.

A brief history of the early days of mycology in Scotland is given to act as a starting point from which to view the fungal records made in the gardens at Sandyford and Kelvinside. The former was vacated in 1842 and the garden transferred to the present site at Kelvinside under the authority of the Glasgow City Council. The role of J.F. Klotzsch in generating the earliest records is emphasised and the compilation of fungal records, mainly of macrofungi, until the present day is discussed. A short account of the microfungi is given. A complete list of the fungi recorded from the two gardens is provided.

The Anthropocene era is characterized by a pronounced negative impact of human and social activities on natural ecosystems. To the extent finance, economics and management underlie human social activities, we need to reassess these fields and their role in achieving global sustainability. This article briefly presents the scientific evidence on accelerating impacts of human activities on nature, which have resulted in breach of planetary boundaries and onset of global climate change. It offers some potential leverage points for change toward sustainability stewardship by highlighting the important role of finance and economics in addressing climate change. We examine the role of financial stakeholders in addressing planetary boundaries and offer a modified stakeholder theory, from which we propose future directions for finance in the Anthropocene.

Abstract This book contains 23 chapters divided into seven parts. Part I reviews the key hypotheses in invasion ecology that invoke biotic interactions to explain aspects of plant invasion dynamics; and reviews models, theories and hypotheses on how invasion performance and impact of introduced species in recipient ecosystems can be conjectured according to biotic interactions between native and non-native species. Part II deals with positive and negative interactions in the soil. Part III discusses mutualistic interactions that promote plant invasions. Part IV describes antagonistic interactions that hinder plant invasions, while part V presents the consequences of plant invasions for biotic interactions among native species. In part VI, novel techniques and experimental approaches in the study of plant invasions are shown. In the last part, biotic interactions and the management of ecosystems invaded by non-native plants are discussed.
