2Silvicultural alternatives to conventional even-aged forest man-agement-what limits global adoption?显示文摘Background: The development of forestry as a scientific and management discipline over the last two centuries has mainly emphasized intensive management operations focused on increased commodity production, mostly wood. This 'conventional' forest management approach has typically favored production of even-aged, single-species stands. While alternative management regimes have generally received less attention, this has been changing over the last three decades, especially in countries with developed economies. Reasons for this change include a combination of new information and concerns about the ecological consequences of intensive forestry practices and a willingness on the part of many forest owners and society to embrace a wider set of management objectives. Alternative silvicultural approaches are characterized by a set of fundamental principles, including avoidance of clearcutting, an emphasis on structural diversity and small-scale variability, deployment of mixed species with natural regeneration,and avoidance of intensive site-preparation methods.Methods: Our compilation of the authors' experiences and perspectives from various parts of the world aims to initiate a larger discussion concerning the constraints to and the potential of adopting alternative silvicultural practices.Results: The results suggest that a wider adoption of alternative silvicultural practices is currently hindered by a suite of ecological, economic, logistical, informational, cultural, and historical constraints. Individual contexts display their own unique combinations and relative significance of these constraints, and accordingly, targeted efforts, such as regulations and incentives, may help to overcome specific challenges.Conclusions: In a broader context, we propose that less emphases on strict applications of principles and on stand structures might provide additional flexibility and facilitate the adoption of alternative silvicultural regimes in a broader set of circumstances. At the same time, the acceptance of alternative silvicultural systems as the 'preferred or default mode of management' wil necessitate and benefit from the continued development of the scientific basis and valuation of a variety of ecosystem goods and services. This publication is aimed to further the discussion in this context.Klaus J Puettmann Scott McG Wilson Susan C Baker Pablo J Donoso Lars Dr?ssler Girma Amente Brian D Harvey Thomas Knoke Yuanchang Lu Susanna Nocentini Francis E Putz Toshiya Yoshida Jürgen Bauhus 2015Forest Ecosystems2015,2,2:4
3Juicy Stories on Female Reproductive Tissue Development: Coordinating the Hormone Flows显示文摘In the past 20–30 years,developmental biologists have made tremendous progress in identifying genes required for the specifcation of individual cell types of an organ and in describing how they interact in genetic networks.In comparison,very little is known about the mechanisms that regulate tissue polarity and overall organ patterning.Gynoecia and fruits from members of the Brassicaceae family of fowering plants provide excellent model systems to study organ patterning and tissue specifcation because they become partitioned into distinct domains whose formation is determined by polarity establishment both at a cellular and whole tissue level.Interactions among key regulators of Arabidopsis gynoecium and fruit development have revealed a network of upstream transcription factor activities required for such tissue differentiation.Regulation of the plant hormone auxin is emerging as both an immediate downstream output and input of these activities,and here we aim to provide an overview of the current knowledge regarding the link between auxin and female reproductive development in plants.In this review,we will also demonstrate how available data can be exploited in a mathematical modeling approach to reveal and understand the feedback regulatory circuits that underpin the polarity establishment,necessary to guide auxin flows.Veronica A.Grieneisen Athanasius F.M.Marée Lars φstergaard 2013Journal of Integrative Plant Biology2013,55,9:2
