The Pacific Northwest Research Station's Biodiversity Initiative: Collaborating For Biodiversity Management

The Pacific Northwest Research Station launched a Biodiversity Initiative to assist natural resource professionals in integrating complex biodiversity concepts into natural resource management processes. We canvassed clients from various affiliations to determine the main challenges they face in biodiversity management, to define their information needs, and to understand how best to deliver biodiversity information within a collaborative framework. The biodiversity management challenges that emerged included (1) the lack of well-defined biodiversity management policies, (2) understanding and quantifying the interaction effects between a number of factors (e.g., disturbance types, management practices) and biodiversity, (3) the lack of applied biodiversity monitoring strategies, (4) difficulty in locating and accessing biodiversity information, and (5) balancing conflicting values relating to biodiversity. We also list the biodiversity information product needs of clients, as well as preferred technology transfer methods, and we discuss the future direction of the Biodiversity Initiative.

Lichen bioindication of biodiversity, air quality, and climate: baseline results from monitoring in Washington, Oregon, and California

Lichens are highly valued ecological indicators known for their sensitivity to a wide variety of environmental stressors like air quality and climate change. This report summarizes baseline results from the U.S. Department of Agriculture, Forest Service, Forest Inventory and Analysis (FIA) Lichen Community Indicator covering the first full cycle of data collection (1998-2001, 2003) for Washington, Oregon, and California. During this period, FIA conducted 972 surveys of epiphytic macrolichen communities for monitoring both spatial and long-term temporal trends in forest health. Major research findings are presented with emphasis on lichen biodiversity as well as bioindication of air quality and climate. Considerable effort is devoted to mapping geographic patterns and defining lichen indicator species suitable for estimating air quality and climate.

Traditional and local ecological knowledge about forest biodiversity in the Pacific Northwest

This paper synthesizes the existing literature about traditional and local ecological knowledge relating to biodiversity in Pacific Northwest forests in order to assess what is needed to apply this knowledge to forest biodiversity conservation efforts. We address four topics: (1) views and values people have relating to biodiversity, (2) the resource use and management practices of local forest users and their effects on biodiversity, (3) methods and models for integrating traditional and local ecological knowledge into biodiversity conservation on public and private lands, and (4) challenges to applying traditional and local ecological knowledge for biodiversity conservation. We focus on the ecological knowledge of three groups who inhabit the region: American Indians, family forest owners, and commercial nontimber forest product (NTFP) harvesters.

Diversity, ecology, and conservation of truffle fungi in forests of the Pacific Northwest

Forests of the Pacific Northwest have been an epicenter for the evolution of truffle fungi with over 350 truffle species and 55 genera currently identified. Truffle fungi develop their reproductive fruit-bodies typically belowground, so they are harder to find and study than mushrooms that fruit aboveground. Nevertheless, over the last five decades, the Corvallis Forest Mycology program of the Pacific Northwest Research Station has amassed unprecedented knowledge on the diversity and ecology of truffles in the region. Truffle fungi form mycorrhizal symbioses that benefit the growth and survival of many tree and understory plants. Truffle fruit-bodies serve as a major food souce for many forest-dwelling mammals. A few truffle species are commercially harvested for gourmet consumption in regional restaurants. This publication explores the biology and ecology of truffle fungi in the Pacific Northwest, their importance in forest ecosystems, and effects of various silvicultural practices on sustaining truffle populations. General management principles and considerations to sustain this valuable fungal resource are provided.

Building a citizen-agency partnership among diverse interests: the Colville National Forest and Northeast Washington Forestry Coalition Experience

Concerns about forest health and the threat of wildfire across the Western United States increasingly provide the impetus for communities to find land management solutions that serve multiple interests. Funding and procedural changes over the past decade have positioned federal agencies to put greater emphasis on multistakeholder partnerships and public outreach efforts. Partnerships build slowly over time, but can result in a healthier resource, reduced fire risk, greater stability for agency planning processes, and more resilient communities. Drawing on interviews with stakeholders representing broad interests in a partnership between the Northeast Washington Forestry Coalition and the Colville National Forest, we examine some of the critical factors leading to the partnership's success and identify challenges along the way. We illustrate how the citizens of Colville, Washington, overcame conflicts by learning to communicate their interests and use existing resources to advance a variety of goals, ranging from fuels reduction and active forest management to roadless area and wilderness management. We highlight a set of important organizational themes that have emerged from Colville to provide managers and other stakeholders with ideas for similar efforts.

Distancing and diversity enhance Iowa’s food security

Coronavirus provides a chilling lesson about crowding. The disease originated in a densely packed Chinese City. As it moved worldwide it struck most heavily in crowded places where people live and work in proximity.

Medical experts advise us to stay home and keep fellow humans at a distance. Isolation works. If a pathogen can’t reach us it can’t cause harm.

The same holds true for food. Years ago farmers planted diverse crops in relatively small fields, and raised modest numbers of chickens, pigs, and cattle. One cornfield or chicken coop was, essentially, isolated from the next closest counterpart, making it hard for a disease to jump from one farm to the next.

Modern Agriculture, in contrast, raises hundreds of thousands of chickens and turkeys crowded together in single buildings. Hogs and cattle are also crammed together, as are crops. Essentially the Midwest is one continuous cornfield stretching from Ohio to Nebraska. Once a pathogen mutates a new disease can easily sweep across vast fields or through crowded growing buildings, leaving a path of death and food shortages in its wake.

Modern mass agriculture is efficient, providing consumers with inexpensive eggs, milk, vegetables and meat, but it is vulnerable. Today’s farmers recognize disease potential and practice scrupulous biosecurity to keep pathogens away from their crops and animals. Still, all it takes is one mutation or introduction of a foreign microbe and a high percentage of American food is lost.

Families can reduce their vulnerability to mass food production by growing some at home. During The Second World War the government encouraged families to plant victory gardens and keep one to two hens per family member. Many households were able to grow up to 40% of their annual dietary needs, even in small yards. It freed commercially produced food for the military. Yards remain capable of growing significant quantities of nutritious food using three techniques.

Gardening: An amazing quantity of nutritious food can be grown in even a small sunny backyard, especially when intensive gardening techniques are used.

Foraging: Delicious wild foods grow in unsprayed yards and are free for the picking. Our family, for example, enjoys nettles, lambsquarters, purslane, acorns and dandelions. Learning to identify, harvest, and process them is not difficult. Ironically spraying a yard kills plants people can eat to favor inedible grass.

Chickens: A six hen backyard flock will produce two dozen eggs a week. They need some commercial feed but recycle kitchen scraps and garden weeds into eggs. Cedar Rapids and other towns allow families to keep chickens with a few restrictions.

Families unable or unwilling to grow backyard food can boost food security by buying vegetables, meat and eggs from small local producers.

Coronavirus has taught us about contagion and helps clarify the threat that mass production poses. Raising backyard food enhances resilience. It’s satisfying and helps ensure there will be something to eat.

Rich Patterson of Cedar Rapids is a writer, former nature center director and ecological consultant who co-owns Winding Pathways LLC with his wife, Marion.

Jealousy-freeness and other common properties in Fair Division of Mixed Manna. (arXiv:2004.11469v2 [cs.GT] UPDATED)

We consider a fair division setting where indivisible items are allocated to agents. Each agent in the setting has strictly negative, zero or strictly positive utility for each item. We, thus, make a distinction between items that are good for some agents and bad for other agents (i.e. mixed), good for everyone (i.e. goods) or bad for everyone (i.e. bads). For this model, we study axiomatic concepts of allocations such as jealousy-freeness up to one item, envy-freeness up to one item and Pareto-optimality. We obtain many new possibility and impossibility results in regard to combinations of these properties. We also investigate new computational tasks related to such combinations. Thus, we advance the state-of-the-art in fair division of mixed manna.

Fine-Grained Analysis of Cross-Linguistic Syntactic Divergences. (arXiv:2005.03436v1 [cs.CL])

The patterns in which the syntax of different languages converges and diverges are often used to inform work on cross-lingual transfer. Nevertheless, little empirical work has been done on quantifying the prevalence of different syntactic divergences across language pairs. We propose a framework for extracting divergence patterns for any language pair from a parallel corpus, building on Universal Dependencies. We show that our framework provides a detailed picture of cross-language divergences, generalizes previous approaches, and lends itself to full automation. We further present a novel dataset, a manually word-aligned subset of the Parallel UD corpus in five languages, and use it to perform a detailed corpus study. We demonstrate the usefulness of the resulting analysis by showing that it can help account for performance patterns of a cross-lingual parser.

Fact-based Dialogue Generation with Convergent and Divergent Decoding. (arXiv:2005.03174v1 [cs.CL])

Fact-based dialogue generation is a task of generating a human-like response based on both dialogue context and factual texts. Various methods were proposed to focus on generating informative words that contain facts effectively. However, previous works implicitly assume a topic to be kept on a dialogue and usually converse passively, therefore the systems have a difficulty to generate diverse responses that provide meaningful information proactively. This paper proposes an end-to-end Fact-based dialogue system augmented with the ability of convergent and divergent thinking over both context and facts, which can converse about the current topic or introduce a new topic. Specifically, our model incorporates a novel convergent and divergent decoding that can generate informative and diverse responses considering not only given inputs (context and facts) but also inputs-related topics. Both automatic and human evaluation results on DSTC7 dataset show that our model significantly outperforms state-of-the-art baselines, indicating that our model can generate more appropriate, informative, and diverse responses.

Individual-specific information generation apparatus and individual-specific information generation method

The generation of individual-specific information having a good reliability and uniqueness is made possible with a little circuit scale. For this purpose, in an individual-specific information generation apparatus, a plurality of digital circuits are in the same circuit configuration. Each of the digital circuits outputs a fixed or a random number output value individually without their output with respect to a certain input being determined unambiguously among the digital circuits. In each of the digital circuit, an order is defined in advance. A random number judgment unit judges whether the output value is a random value or fixed, for each of the plurality of digital circuits. An individual-specific information generation unit generates the individual-specific information based on information of the order defined in the digital circuit judged by the random number judgment unit as having a fixed output value among the plurality of digital circuits and the output value.
