Drought as an emergent driver of ecological transformation in the twenty-first century.

Under climate change, ecosystems are experiencing novel drought regimes, often in combination with stressors that reduce resilience and amplify drought's impacts. Consequently, drought appears increasingly likely to push systems beyond important physiological and ecological thresholds, resulting in substantial changes in ecosystem characteristics persisting long after drought ends (i.e.

How Should a One Health Perspective Promote Cross-Disciplinary Research About Bat-Associated Viruses in Uganda?

Bats are diverse mammals that are globally distributed and ecologically critical, yet some bat species are associated with disease agents that have severe consequences for human health. Disease outbreak responses require interdisciplinary knowledge of bat-associated pathogens and microbial transmission patterns. Health promotion requires close, collaborative attention to the needs, vulnerabilities, and interests of diverse stakeholders, including the public and professionals in public health, conservation, ecology, social science, communication, and policy.

Answers to Patient, Student, and Clinician Questions About How Animals Are Slaughtered and Used for Food.

"Do cattle and other animals know they are walking up a chute that will lead to their death?" Many people ask this question, which the author first had to answer when starting work in the cattle industry. From observations at slaughter plants, feedlots, and ranches, the author learned that cattle behavior was the same when entering a chute for vaccination and when entering a chute for slaughter. If cattle knew they would die, their behavior should have been wilder and more agitated at the slaughter plant, but that was clearly not the case.

Nutritional Content and Ingredients of Commercial Infant and Toddler Food Pouches Compared With Other Packages Available in the United States.

The ingredients and nutrients of infant and toddler foods (ITFs) sold in pouches were compared with products available in other packages, such as jars/packs and other containers. Company websites (n = 21) and in-store shelf inventory (n = 3) were used to create a database of commercial ITFs containing vegetables (n = 548) sold in the United States. Results indicated that ITFs containing vegetables were most commonly packaged in pouches (50%), followed by "other" packages (25%) and jars/packs (25%).

Reversing resistance to tembotrione in an Amaranthus tuberculatus (var. rudis) population from Nebraska, USA with cytochrome P450 inhibitors.

Background: A population of Amaranthus tuberculatus (var. rudis) was confirmed resistant to 4-hydroxyphenylpyruvate dioxygenase (HPPD)-inhibitor herbicides (mesotrione, tembotrione, and topramezone) in a seed corn/soybean rotation in Nebraska. Further investigation confirmed a non-target-site resistance mechanism in this population.

Role of Feline Immunodeficiency Virus in Lymphomagenesis--Going Alone or Colluding?

Feline immunodeficiency virus (FIV) is a naturally occurring lentivirus of domestic and nondomestic feline species. Infection in domestic cats leads to immune dysfunction via mechanisms similar to those caused by human immunodeficiency virus (HIV) and, as such, is a valuable natural animal model for acquired immunodeficiency syndrome (AIDS) in humans. An association between FIV and an increased incidence of neoplasia has long been recognized, with frequencies of up to 20% in FIV-positive cats recorded in some studies.
