Understanding The Effect Of Ranching On Quercus Brandegeei Recruitment In The Sierra La Laguna Biosphere Reserve, Xavier O. Espinoza
Understanding The Effect Of Ranching On Quercus Brandegeei Recruitment In The Sierra La Laguna Biosphere Reserve, Xavier O. Espinoza
DePaul Discoveries
In this study, we attempt to deepen our understanding of the mechanisms responsible for Quercus brandegeei’s observed lack of regeneration by identifying which animal species (wild and domesticated) most frequently were observed eating, passing by, or searching for seeds and seedlings. We established 10 paired plots (10 enclosed and 10 immediately outside enclosures) and positioned one motion-activated camera in each plot to observe animal visitations to Quercus brandegeei individuals over the course of several months (October 2019 – March 2020). No seeds and seedlings survived outside of enclosed areas at the end of the study based on their absence. Very …

Bobwhite Response To Cattle Grazing In South Texas, Bradley K. Johnston, J. Alfonso Ortega-S., Leonard A. Brennan, Fidel Hernández, Humberto L. Perotto-Baldivieso
National Quail Symposium Proceedings
Range management practices to improve habitat for wildlife by reducing brush and increasing herbaceous plants, coupled with reduced stocking rates, can lead to dense stands of dominant grasses, such as four-flower trichloris (Trichloris pluriflora). This monoculture of trichloris creates dense vegetation unsuitable for northern bobwhite (Colinus virginianus; hereafter, bobwhite), reduces plant species diversity, and alters ecosystem functions. The objectives of this study are to 1) evaluate the effects of a proper cattle grazing regime to improve bobwhite habitat and 2) develop a management guide documenting how cattle grazing can be used as a tool to reduce …
Human–Carnivore Conflicts In A Recently Established Pakistani National Park, Rukhsana Khatoon, Maqsood Anwar, Charles H. Nilon, Matthew E. Gompper
Human–Carnivore Conflicts In A Recently Established Pakistani National Park, Rukhsana Khatoon, Maqsood Anwar, Charles H. Nilon, Matthew E. Gompper
Human–Wildlife Interactions
Human–carnivore conflicts (HCCs) are increasing globally. These conflicts may encompass competition for food resources, crop and livestock depredations, and attacks on humans. Concerns over conflicts may result in retaliatory killings of carnivores and negative views of wildlife or landscape conservation. Yet, despite the economic and conservation implications of HCCs, data regarding the magnitude and severity of the conflicts may be lacking because many incidents are unreported. To better inform this issue, we compared HCC data for 2016 to 2018 obtained from official records of the Punjab Wildlife and Parks Department for a newly established national park in the Punjab Region …

Research The Chopper Apparatus Of Equipment For Chopping Pressed Rough Fodders, Sh.H. Gapparov, N.A. Ashurov
Irrigation and Melioration
Livestock is one of the most important agricultural sectors in Uzbekistan and it is based on family livestock farms. On family farms, livestock animals are fed with pressed roughage, including corn stalks, alfalfa hay, barbed straw and wheat straw, mixed with concentrated feed. However, due to the lack of small choppers suitable for small farms, the compressed feed is fed to animals without chopping, as a result of which about 25-30 percent of them go to waste and there are large losses. Taking this into account, a small device was developed for chopping pressed roughage and mixing it with concentrated …

Spatial And Temporal Dynamics Of Human–Wildlife Conflicts In The Kenya Greater Tsavo Ecosystem, Joseph M. Mukeka, Joseph O. Ogutu, Erustus Kanga, Eivin Røskaft
Human–Wildlife Interactions
Biodiversity conservation in developing countries is faced with many and mounting challenges, including increasing human–wildlife conflicts (HWCs). In Africa and other developing countries, increasing HWCs, particularly those adjacent to protected areas, can adversely affect local stakeholder perceptions and support for conservation. We analyzed HWC reports for multiple wildlife species compiled >23 years (1995–2017) from the Greater Tsavo Ecosystem (GTE) in Kenya to determine HWC trends. The GTE is the largest protected area in Kenya, covering 22,681 km2. Overall, 39,022 HWC incidents were reported in 6 GTE regions (i.e., Taveta, Mutomo, Kibwezi, Rombo, Galana, Bachuma).

Distribution And Activity Patterns Of Large Carnivores And Their Implications For Human–Carnivore Conflict Management In Namibia, Summer Fink, Richard Chandler, Michael Chamberlain, Steven Castleberry, Shannon Glosenger-Thrasher
Human–Wildlife Interactions
Human–wildlife conflicts (HWCs) are increasing globally and contributing to the decline of wildlife species. In sub-Saharan African countries such as Namibia, most of the suitable land has been or is currently being converted to crop and livestock production to support income or subsistence agriculture. These changes in land use often incur increased levels of HWCs because of crop and livestock depredation by native species. To quantify livestock predation risks posed by carnivores in Namibia, we deployed 30 trail cameras on a 6,500-ha farm in the Khomas region of Namibia from May to July 2018. We developed occupancy models to make …
A Strategy To Predict The Global Warming Gas From Stock Farming —Potential Scaling Law Of The Released Methane From Livestock—, Toshiaki Nakashima, Tsuneyoshi Matsuoka, Yuji Nakamura
A Strategy To Predict The Global Warming Gas From Stock Farming —Potential Scaling Law Of The Released Methane From Livestock—, Toshiaki Nakashima, Tsuneyoshi Matsuoka, Yuji Nakamura
Progress in Scale Modeling, an International Journal
This work examines a scaling approach to predict the amount of methane released from the daily activity of livestock on farms. The subject animals are ruminants, i.e. having rumen or a ruminant stomach, that generates methane through digestion processes via several microbial fermentation steps. The produced methane is mixed into their breathing and released into the atmosphere. Existing data on methane released from various kinds of ruminant livestock were correlated as a power function of an animal’s weight, with an exponent near 0.92. This value is larger than a value of 0.75 which was related to the general metabolism rates …

New Approach To Health And The Environment To Avoid Future Pandemics, Serge Morand
Animal Sentience
This commentary expands Wiebers & Feigin’s target article by pinpointing how declining wildlife, expanding livestock and globalisation contribute to the increase in epidemics of zoonotic diseases, the COVID-19 crisis and future health crises. Epidemics and the emergence of zoonoses are manifestations of dysfunctional links with animals, both wild and domestic, requiring a new approach to health and the environment.

Carnivore-Livestock Conflicts In Chile: Evidence And Methods For Mitigation, Valeska Rodriguez, Daniela A. Poo-Muñoz, Luis E. Escobar, Francisca Astorga, Gonzalo Medina-Vogel
Human–Wildlife Interactions
Human population growth and habitat loss have exacerbated human–wildlife conflicts worldwide. We explored trends in human–wildlife conflicts (HWCs) in Chile using scientific and official reports to identify areas and species with higher risk of conflicts and tools available for their prevention and mitigation. The puma (Puma concolor) was considered the most frequent predator; however, fox (Lycalopex spp.) and free-ranging or feral dog (Canis lupus familiaris) attacks were also common. Our results suggest that the magnitude of puma conflicts may be overestimated. Domestic sheep (Ovis spp.) and poultry (Galliformes) were the most common species predated. …
Applied Cognition Research To Improve Sheep Welfare, Kristina Horback
Applied Cognition Research To Improve Sheep Welfare, Kristina Horback
Animal Sentience
If a change is going to occur in the care and management of domestic sheep, there needs to be a collaborative effort across many disciplines. This review by Marino & Merskin of the literature on cognitive processing in domestic sheep is limited by the inherent bias of the authors, including the impracticable goal of eliminating sheep production. Animal welfare concerns about the management of commercial sheep are valid; however, in order to make a difference, we need to develop an application for this knowledge about cognitive abilities in sheep.

A Content Analysis Of Antibiotic Use In Livestock In National U.S. Newspapers, Garrett M. Steede, Courtney Meyers, Nan Li, Erica Irlbeck, Sherice Gearhart
Journal of Applied Communications
The discovery of the antibiotic Aureomycin as a growth promotor for the livestock industry was viewed as revolutionary in 1950. The use of antibiotics as growth promoters in livestock, however, has been questioned by health professionals concerned with the role this use might play in the development of antibiotic resistant bacteria. As a public health issue, newspapers have covered this topic since its discovery. Media, such as newspapers, have used frames to discuss the topic over time as new discoveries have occurred, policy changes have been implemented, and food animal production has changed. The purpose of this study was to …

Turkish Journal of Zoology
Disturbance is an important factor affecting community composition and biodiversity in natural ecosystems. The Ventania hill system in central Argentina presents several ecosystem disturbances. Spiders are good candidates for studies related to human impact and conservation, as they can be good biological indicators of certain ecosystems. Therefore, we tried to elucidate if the abundance and spatial distribution of the mygalomorph spider Acanthogonatus centralis (Nemesiidae) are affected by different degrees of disturbance in these hilly grasslands. We studied 3 sites with different levels of disturbance located in the Ventania system in southwestern Buenos Aires Province, Argentina. We did not find differences …

A Sentiment And Content Analysis Of Twitter Content Regarding The Use Of Antibiotics In Livestock, Garrett M. Steede, Courtney Meyers, Nan Li, Erica Irlbeck, Sherice Gearhart
Journal of Applied Communications
On January 1, 2017, the final rule of the Veterinary Feed Directive (VFD) was put into place requiring antibiotics approved for both humans and animals to be discontinued for growth promotion. This change was brought on by the role growth promoters in livestock production play in the development of antibiotic resistance. Antibiotic resistance increases the costs associated with human health care by increasing the length of stays in the hospital and requiring more intensive medical care for patients. The purpose of this study was to explore sentiment and characteristics of social media content and the characteristics of the key influencers …

Learning To Live With Wolves: Community-Based Conservation In The Blackfoot Valley Of Montana, Seth M. Wilson, Elizabeth H. Bradley, Gregory A. Neudecker
Learning To Live With Wolves: Community-Based Conservation In The Blackfoot Valley Of Montana, Seth M. Wilson, Elizabeth H. Bradley, Gregory A. Neudecker
Human–Wildlife Interactions
We built on the existing capacity of a nongovernmental organization called the Blackfoot Challenge to proactively address wolf (Canis lupus)-livestock conflicts in the Blackfoot Valley of Montana. Beginning in 2007, wolves started rapidly recolonizing the valley, raising concerns among livestock producers. We built on an existing program to mitigate conflicts associated with an expanding grizzly bear population and worked within the community to build a similar program to reduce wolf conflicts using an integrative, multi-method approach. Efforts to engage the community included one-on-one meetings, workshops, field tours, and regular group meetings as well as opportunities to participate in …

Human–Wildlife Interactions
The economics of managing disease transmission at the wildlife–livestock interface have received heightened attention as agricultural and natural resource agencies struggle to tackle growing risks to animal health. In the fiscal landscape of increased scrutiny and shrinking budgets, resource managers seek to maximize the benefits and minimize the costs of disease mitigation efforts. To address this issue, a benefit-cost analysis decision framework was developed to help users make informed choices about whether and how to target disease management efforts in wildlife and livestock populations. Within the context of this framework, we examined the conclusions of a bene� t-cost analysis conducted …

Mixed-Breed Guarding Dogs Reduce Conflict Between Goat Herders And Native Carnivores In Patagonia, Alejandro González, Andrés Novaro, Martín Funes, Oscar Pailacura, María Jose Bolgeri, Susan Walker
Mixed-Breed Guarding Dogs Reduce Conflict Between Goat Herders And Native Carnivores In Patagonia, Alejandro González, Andrés Novaro, Martín Funes, Oscar Pailacura, María Jose Bolgeri, Susan Walker
Human–Wildlife Interactions
Goat husbandry is the main rural livelihood in the northern Patagonian steppe of Argentina, and herders kill any carnivore that they believe threatens their herds, including the endangered Andean cat (Leopardus jacobita). We evaluated the use of local, mediumsized, mixed-breed guarding dogs to reduce predation and retaliatory killing of carnivores. We interviewed 64 herders, and delivered 37 puppies to 25 herders. Most economic loss was attributed to cougars (Puma concolor) and culpeos (Lycalopex culpaeus). All herders with dogs that reached the working stage reported reduced rates of predation, and 88% reported that they no …

The objective of this study was to determine the changes in hay yield and quality components at different phenological stages of a bulbous barley (Hordeum bulbosum L.) population handpicked from natural flora during 2003-2007 in Samsun, Turkey. The phenological stages of bulbous barley during spring-summer (grazing maturity, early heading, heading, and milk-dough) and autumn (early growing) were investigated. Significant differences were observed in hay yield, relative feed value (RFV), crude protein (CP), acid and neutral detergent fiber (ADF and NDF), Ca, Mg, K, P, Mn, Fe, and Zn concentrations, and K(Ca + Mg)^{-1} and Ca P^{-1} ratios of DM, depending …
Global Economics Of Nutrient Cycling, Bert H. Janssen, Oene Oenema
Global Economics Of Nutrient Cycling, Bert H. Janssen, Oene Oenema
Turkish Journal of Agriculture and Forestry
This paper briefly discusses global human requirements of protein nitrogen (N) from crops and animals, and then estimates the need for fertilizer N as a function of N use efficiency, and the recycling of N from animal manure and sewage wastes. These estimates are based on various assumptions and simple calculations. Results suggest that globally only 1% of N input is retained, 28% is lost to the wider environment, and some 70% is potentially available for recycling via manure and sewage. In addition, large amounts of nutrients recycle via crop residues. In practice, only a fraction of this potential is …

170 Years Of Caring: The Animal Welfare Movement In Bangor, Maine, John D. Blaisdell
170 Years Of Caring: The Animal Welfare Movement In Bangor, Maine, John D. Blaisdell
Maine History
The history of the animal welfare movement in Bangor, Maine dates to the first decades of the nineteenth century: Over the course of its long history, the movement's emphasis shifted from a focus on livestock and urban workhorses in the nineteenth century to children and animals at the turn of the century and finally to companion animals, primarily cats and dogs. These shifts, the author argues, reflect economic and technological changes as well as a transformation in society's perception of animals. A Maine native, John Blaisdell, is currently working on a book exploring the history of Maine's animal welfare movement. …
