Divide and conquer: using RhizoVision Explorer to aggregate data from multiple root scans using image concatenation and statistical methods.

Roots are important in agricultural and natural systems for determining plant productivity and soil carbon inputs. Sometimes, the amount of roots in a sample is too much to fit into a single scanned image, so the sample is divided among several scans, and there is no standard method to aggregate the data. Here, we describe and validate two methods for standardizing measurements across multiple scans: image concatenation and statistical aggregation.

Companion Animals' Roles for AIDS Survivors, Mostly Aging Males, during HIV/AIDS and COVID-19 Pandemics.

Long-term HIV/AIDS survivors responded online concerning their experiences during the AIDS and COVID pandemics. Recruited from web-based organizations for AIDS survivors, 147 answered questions on: frequency of experiencing stigma, isolation, aloneness, or grief/sadness; pet ownership; and sources of human support during each pandemic. Conditional inference trees were run to identify relevant demographic factors.

Variation in Bacterial Community Structure Under Long-Term Fertilization, Tillage, and Cover Cropping in Continuous Cotton Production.

Agricultural practices alter the structure and functions of soil microbial community. However, few studies have documented the alterations of bacterial communities in soils under long-term conservation management practices for continuous crop production. In this study, we evaluated soil bacterial diversity using 16S rRNA gene sequencing and soil physical and chemical properties within 12 combinations of inorganic N fertilization, cover cropping, and tillage throughout a cotton production cycle.

Permafrost Active Layer Microbes From Ny Ålesund, Svalbard (79°N) Show Autotrophic and Heterotrophic Metabolisms With Diverse Carbon-Degrading Enzymes.

The active layer of permafrost in Ny Ålesund, Svalbard (79°N) around the Bayelva River in the Leirhaugen glacier moraine is measured as a small net carbon sink at the brink of becoming a carbon source. In many permafrost-dominating ecosystems, microbes in the active layers have been shown to drive organic matter degradation and greenhouse gas production, creating positive feedback on climate change. However, the microbial metabolisms linking the environmental geochemical processes and the populations that perform them have not been fully characterized.

Protecting Animal Welfare in Animal-Assisted Intervention: Our Ethical Obligation.

When incorporating therapy animals into clinical practice, there are essential ethical considerations that must be considered to protect the welfare of both the people and the animals who are involved in the intervention. The field of animal-assisted interventions (AAIs) and more specifically animal-assisted therapy (AAT) is just beginning to appreciate the critical role that animal welfare has in enhancing the quality of the entire process of working with a therapy animal. In this article, the authors will present ethical models that are incumbent for practitioners to consider prior to partnering with a therapy animal.

The Animal Welfare Science of Working Dogs: Current Perspectives on Recent Advances and Future Directions.

Working dogs are prevalent throughout our societies, assisting people in diverse contexts, from explosives detection and livestock herding, to therapy partners. Our scientific exploration and understanding of animal welfare have grown dramatically over the last decade. As community attitudes toward the use of animals continue to change, applying this new knowledge of welfare to improve the everyday lives of working dogs will underpin the sustainability of working with dogs in these roles.

Advancing Human-Animal Interaction to Counter Social Isolation and Loneliness in the Time of COVID-19: A Model for an Interdisciplinary Public Health Consortium.

The mental and physical human costs of social isolation and loneliness-and their possible amelioration through human-animal interaction (HAI)-have both received intense attention since the onset of the COVID-19 pandemic, and its lockdowns, quarantines, and related mitigation measures. Concern about society's "loneliness epidemic", however, predates the pandemic, as does serious inquiry into HAI as a positive intervention. Recognizing the potential of companion animals to make a difference on an important public health issue, the Consortium on Social Isolation and Companion Animals-a novel partnership of the Human Animal Bond Research Institute (HABRI) and Mars Petcare-launched a joint initiative in 2019 to advance HAI research, address barriers to HAI, and support best practices in bringing together animals and people to ease loneliness.

The New Era of Canine Science: Reshaping Our Relationships With Dogs.

Canine science is rapidly maturing into an interdisciplinary and highly impactful field with great potential for both basic and translational research. The articles in this Research Topic, , arise from two meetings sponsored by the Wallis Annenberg PetSpace Leadership Institute, which convened experts from diverse areas of canine science to assess the state of the field and challenges and opportunities for its future. In this final paper, we identify a set of overarching themes that will be critical for a productive and sustainable future in canine science.

A Commentary on the Contemporary Issues Confronting Animal Assisted and Equine Assisted Interactions.

The field of human-animal interactions and, more specifically, animal-assisted interventions and equine assisted interactions (equine assisted interactions have significantly evolved over the past half century. The primary purpose of this paper is to provide a brief commentary of both fields and the challenges they are presently experiencing as they move forward in their future. More specifically within this commentary, attention will be given to highlighting some of the directions taken in both fields, including clarifying their terminology as it applies to scope of practices, trends in research and practice, the need to emphasize the welfare of the animals as well as the possible directions to standardized professional competencies and the needed professional development.

Dogs Supporting Human Health and Well-Being: A Biopsychosocial Approach.

Humans have long realized that dogs can be helpful, in a number of ways, to achieving important goals. This is evident from our earliest interactions involving the shared goal of avoiding predators and acquiring food, to our more recent inclusion of dogs in a variety of contexts including therapeutic and educational settings. This paper utilizes a longstanding theoretical framework- the biopsychosocial model- to contextualize the existing research on a broad spectrum of settings and populations in which dogs have been included as an adjunct or complementary therapy to improve some aspect of human health and well-being.

Considerations for the Retirement of Therapy Animals.

With the growth of animal-assisted interventions, the number of animals designated to work as therapy animals continues to increase. These animals participate in this work in varying capacities during life, but there will be a point in time when the animal can no longer engage in these activities. The concept of retirement, or withdrawing the animal from its working life, is an important phase of life that every therapy animal will inevitably face.

The State of Animal-Assisted Interventions: Addressing the Contemporary Issues that will Shape the Future.

As the worldwide popularity of animal-assisted interventions (AAIs) increases, the fieldis quickly approaching a paradigm shift, adjusting its image to incorporate more evidence-basedresearch and aligning its purpose for advancing a new future. Contemporary critical issues thatconfront the field today include, but are not limited, to research, animal welfare, practice guidelines,and public policy. This article will provide an overview of the history of AAI and the majormilestones that the field has undergone.

Paving the Path Toward Retirement for Assistance Animals: Transitioning Lives.

Assistance animals play significant roles in human therapy and well-being and represent a rapidly growing demographic of animals in society. Most research in the field of assistance animals has been focused on the effect of these animals on people. Only recently has there been a growing interest in the welfare and well-being of these animals and the effect of the work on the animals themselves.

The Role of Animal Assisted Intervention on Improving Self-Esteem in Children With Attention Deficit/Hyperactivity Disorder.

Attention Deficit/Hyperactivity Disorder (ADHD), the most ubiquitous mental health problem in children, has been associated with poor self-esteem. Psychosocial interventions have aimed to improve self-esteem among this group, with the aim of reducing the development of comorbid depression and anxiety. The present study implemented a randomized control design to examine the possibility of Animal Assisted Interventions (AAI) as a viable approach to improving self-esteem among children with ADHD.

Veterinarians and Humane Endings: When Is It the Right Time to Euthanize a Companion Animal?

Current advances in technologies and treatments provide pet owners and veterinarians with more options for prolonging the life of beloved pets, but can simultaneously lead to ethical dilemmas relating to what is best for both animal and owner. Key tools for improving end-of-life outcomes include (1) sufficient training to understand the valid ethical approaches to determining when euthanasia is appropriate, (2) regular training in client communication skills, and (3) a standard end-of-life protocol that includes the use of quality of life assessment tools, euthanasia consent forms, and pet owner resources for coping with the loss of a pet. Using these tools will improve outcomes for animals and their owners and reduce the heavy burden of stress and burnout currently being experienced by the veterinary profession.

Standing the test of time: Reflecting on the relevance today of Levinson's Pet-Oriented Child Psychotherapy.
