Next-Generation Remote Sensing Data at Multiple Spatial Scales Improves Understanding of Habitat Selection by a Small Mammal.

Recent advances in optical remote sensing (RS) technology in combination with lightweight Global Positioning System (GPS) tracking devices now make analyzing the multi-scale habitat selection (HS) of small mammals < 2 kg possible. However, there have been relatively few multi-scale HS studies integrating fine-scale RS data with data-rich, GPS-derived movement data from small mammals. This is critical because small mammals commonly select habitat features across multiple scales.

Measuring the benefit of a defensive trait: Vigilance and survival probability.

Defensive traits are hypothesized to benefit prey by reducing predation risk from a focal predator but come at a cost to the fitness of the prey. Variation in the expression of defensive traits is seen among individuals within the same population, and in the same individual in response to changes in the environment (i.e.

Geographic Patterns of Human Immunodeficiency Virus (HIV) Risk Behaviors Among Older Adults: A Strategy for Identifying Space as a Risk Exposure.

Objectives: This study examined geographical patterns of HIV risk among adults aged 60 and older.

Methods: The 2019 Behavioral Risk Factor Surveillance System (BRFSS) weighted data was used to analyze self-reported participation in HIV risk behaviors among older adults ( = 62,852). Logistic regression models were used on a dichotomous HIV risk variable to map the distribution of HIV risk behaviors across both census regions and divisions.

SNAPSHOT USA 2021: A third coordinated national camera trap survey of the United States.

SNAPSHOT USA is a multicontributor, long-term camera trap survey designed to survey mammals across the United States. Participants are recruited through community networks and directly through a website application (https://www.snapshot-usa.

A scoping review: Forced/coerced sterilization as a socio-cultural risk factor for sexually transmitted HIV for older Black women.

Understanding socio-cultural factors that influence older (age 50 and up) Black women's risk for sexually transmitted HIV has often been absent from policies and programs. This scoping review asked: What does academic literature reveal about forced/coerced sterilization as a risk factor for older Black women who are disproportionately affected by sexually transmitted HIV? Using the Arksey and O'Malley scoping review methodology, the authors identified academic and gray literature published between 2000 and 2023. Of the 407 sources identified and screened, three articles met the criteria for inclusion.

Population origin and heritable effects mediate road salt toxicity and thermal stress in an amphibian.

Human impacts on wild populations are numerous and extensive, degrading habitats and causing population declines across taxa. Though these impacts are often studied individually, wild populations typically face suites of stressors acting concomitantly, compromising the fitness of individuals and populations in ways poorly understood and not easily predicted by the effects of any single stressor. Developing understanding of the effects of multiple stressors and their potential interactions remains a critical challenge in environmental biology.

Overview of the Alaskan Layered Pollution and Chemical Analysis (ALPACA) Field Experiment.

The Alaskan Layered Pollution And Chemical Analysis (ALPACA) field experiment was a collaborative study designed to improve understanding of pollution sources and chemical processes during winter (cold climate and low-photochemical activity), to investigate indoor pollution, and to study dispersion of pollution as affected by frequent temperature inversions. A number of the research goals were motivated by questions raised by residents of Fairbanks, Alaska, where the study was held. This paper describes the measurement strategies and the conditions encountered during the January and February 2022 field experiment, and reports early examples of how the measurements addressed research goals, particularly those of interest to the residents.

Photographic documentation of melanism in bobcats () in the Greater Everglades.

We document the presence of bobcats () that demonstrate melanism in the Greater Everglades. The South Florida landscape is driven by a myriad of disturbance regimes particularly that of short fire intervals. We monitored 180 camera traps for 3 years and obtained 9503 photographs of bobcats 25 (<0.

Rain, recreation and risk: Human activity and ecological disturbance create seasonal risk landscapes for the prey of an ambush predator.

Predation risk and prey responses exhibit fluctuations in space and time. Seasonal ecological disturbances can alter landscape structure and permeability to influence predator activity and efficacy, creating predictable patterns of risk for prey (seasonal risk landscapes). This may create corresponding seasonal shifts in antipredator behaviour, mediated by species ecology and trade-offs between risk and resources.

Advances in stem cell and other therapies for Huntington's disease: An update.

Huntington's disease (HD) is a neurodegenerative disorder caused by an autosomal dominant mutation leading to an abnormal CAG repeat expansion. The result is the synthesis of a toxic misfolded protein, called the mutant huntingtin protein (mHTT). Most current treatments are palliative, but the latest research has expanded into multiple modalities, including stem cells, gene therapy, and even the use of 3D cell structures, called organoids.

Prey species increase activity in refugia free of terrestrial predators.

The decline of terrestrial predator populations across the globe is altering top-down pressures that drive predator-prey interactions. However, a knowledge gap remains in understanding how removing terrestrial predators affects prey behavior. Using a bifactorial playback experiment, we exposed fox squirrels to predator (red-tailed hawks, coyotes, dogs) and non-predator control (Carolina wren) calls inside terrestrial predator exclosures, accessible to avian predators, and in control areas subject to ambient predation risk.

Associations of household factors, hot water temperature, and chlorine residual with Legionella occurrence in single-family homes in New Jersey.

Only 4 % of reported Legionnaires' disease (LD) cases are outbreak-associated and the remaining 96 % are sporadic, for which no known source of Legionella is identified. Although outbreaks of LD are linked to cooling towers, decorative fountains, spas and hot tubs, and other sources, the drivers of sporadic LD are less known. Residential premise plumbing is likely an important source of aerosol exposure and there are unique features of premise plumbing which could lead to proliferation of Legionella.

Fire as a driver and mediator of predator-prey interactions.

Both fire and predators have strong influences on the population dynamics and behaviour of animals, and the effects of predators may either be strengthened or weakened by fire. However, knowledge of how fire drives or mediates predator-prey interactions is fragmented and has not been synthesised. Here, we review and synthesise knowledge of how fire influences predator and prey behaviour and interactions.

Prey tells, large herbivores fear the human 'super predator'.

Fear of the human 'super predator' has been demonstrated to so alter the feeding behavior of large carnivores as to cause trophic cascades. It has yet to be experimentally tested if fear of humans has comparably large effects on the feeding behavior of large herbivores. We conducted a predator playback experiment exposing white-tailed deer to the vocalizations of humans, extant or locally extirpated non-human predators (coyotes, cougars, dogs, wolves), or non-predator controls (birds), at supplemental food patches to measure the relative impacts on deer feeding behavior.

Effects of Bait on Male White-Tailed Deer Resource Selection.

Bait is often used to increase wildlife harvest susceptibility, enhance viewing opportunities, and survey wildlife populations. The effects of baiting depend on how bait influences space use and resource selection at multiple spatial scales. Although telemetry studies allow for inferences about resource selection within home ranges (third-order selection), they provide limited information about spatial variation in density, which is the result of second-order selection.

Value network engagement and effects of memory-related processing during encoding and retrieval of value.

Decision makers rely on episodic memory to calculate choice values in everyday life, yet it is unclear how neural mechanisms of valuation differ when value-related information is encoded versus retrieved from episodic memory. The current fMRI study compared neural correlates of value while information was encoded versus retrieved from memory. Scanned tasks were followed by a behavioral episodic memory test for item-attribute associations.

A comparison of animal color measurements using a commercially available digital color sensor and photograph analysis.

An animal's pelage, feather, or skin color can serve a variety of functions, so it is important to have multiple standardized methods for measuring color. One of the most common and reliable methods for measuring animal coloration is the use of standardized digital photographs of animals. New technology in the form of a commercially available handheld digital color sensor could provide an alternative to photography-based animal color measurements.

ABET Accreditation During and After COVID19 - Navigating the Digital Age.

Engineering accreditation agencies and governmental educational bodies worldwide require programs to evaluate specific learning outcomes information for attainment of student learning and establish accountability. Ranking and accreditation have resulted in programs adopting shortcut approaches to collate cohort information with minimally acceptable rigor for Continuous Quality Improvement (CQI). With tens of thousands of engineering programs seeking accreditation, qualifying program evaluations that are based on reliable and accurate cohort outcomes is becoming increasingly complex and is high stakes.

Narrative Gerontology in Practice: Students' Experiences With Conducting Autoethnography.

This study examines the benefits of introducing autoethnographic writing as part of an ageism intervention to familiarize students with the life course. In this mixed-methods study, 186 graduate and undergraduate students conducted interviews with a grandparent or older adult and subsequently assumed the identity of the grandparent to write introductions of themselves as if they were that grandparent, using "I" statements in an online discussion forum. Most assumed grandparents were women (78.

Effect of mammalian mesopredator exclusion on vertebrate scavenging communities.

Carrion is a valuable resource used by facultative scavengers across the globe. Due to conflicts with humans, many vertebrate scavengers have experienced population declines due to direct persecution or indirect effects of human activities. However, little is known about the implications of altered scavenger community composition on the fate and efficiency of carrion removal within ecosystems.

Mesocarnivores affect hispid cotton rat (Sigmodon hispidus) body mass.

Predator communities are changing worldwide: large carnivores are declining while mesocarnivores (medium-sized mammalian predators) are increasing in number and ecological influence. Predator choice of prey is not random and different predators select prey with different characteristics. Changes in predator communities can change predation patterns experienced by prey.

Effects of the home-based educational intervention on health outcomes among primarily Hispanic children with asthma: a quasi-experimental study.

Background: Childhood asthma is a significant health issue with 8.3% prevalence in the U.S.
