Range-wide salamander densities reveal a key component of terrestrial vertebrate biomass in eastern North American forests.

Characterizing the population density of species is a central interest in ecology. Eastern North America is the global hotspot for biodiversity of plethodontid salamanders, an inconspicuous component of terrestrial vertebrate communities, and among the most widespread is the eastern red-backed salamander, . Previous work suggests population densities are high with significant geographic variation, but comparisons among locations are challenged by lack of standardization of methods and failure to accommodate imperfect detection.

Distress During the COVID-19 Pandemic Among Local Public Health Workers in New York State.

Objective: Understanding the challenges public health workers have faced is critical to reinforcing, revitalizing, and strengthening the public health workforce. We measured and identified the level and causes of psychological distress among public health workers during the COVID-19 pandemic in New York State.

Methods: We used a knowledge, attitudes, beliefs, and behaviors survey to ask public health workers at local health departments about their experiences working in public health during the pandemic, including questions relating to harassment from the public, workload, and work/life balance.

Elevation and blood traits in the mesquite lizard: Are patterns repeatable between mountains?

Ecogeographical patterns describe predictable variation in phenotypic traits between ecological communities. For example, high-altitude animals are expected to show elevated hematological values as an adaptation to the lower oxygen pressure. Mountains act like ecological islands and therefore are considered natural laboratories.

Phenological variation in parasite load and inflammatory response in a lizard with an asynchronous reproductive cycle.

We present the first study that compares phenological variation in parasite load and inflammatory response in a lizard with asynchronous male and female gonadal cycles. Other studies have used many species with seasonal and synchronous reproductive cycles, in which it is difficult to decouple the effects of internal and external factors that can affect parasite abundance in each sex. Species with asynchronous reproductive cycles provide the opportunity to study the effects of seasonality and reproductive condition separately, but few studies have documented variation in parasite abundance in these species.

Long-term ice phenology records spanning up to 578 years for 78 lakes around the Northern Hemisphere.

In recent decades, lakes have experienced unprecedented ice loss with widespread ramifications for winter ecological processes. The rapid loss of ice, resurgence of winter biology, and proliferation of remote sensing technologies, presents a unique opportunity to integrate disciplines to further understand the broad spatial and temporal patterns in ice loss and its consequences. Here, we summarize ice phenology records for 78 lakes in 12 countries across North America, Europe, and Asia to permit the inclusion and harmonization of in situ ice phenology observations in future interdisciplinary studies.

COVID-19 vaccine hesitancy and political ideation among college students in Central New York: The influence of differential media choice.

COVID-19 vaccine hesitancy is context specific and highly dynamic in the United States. The objective of this study was to examine the underlying causes of COVID-19 vaccine use and hesitancy among students at two colleges in Central New York (USA) in order to better understand how to promote vaccination in this demographic. A Knowledge, Attitudes, Beliefs & Behaviors survey was designed to measure the relationship between gender, political ideology, media consumption, beliefs, mental health and anxiety, and pandemic-related behaviors.

Fast and dark: The case of Mezquite lizards at extreme altitude.

Sprint speed is a major performance trait in animal fitness involved in escaping from predators, obtaining food, and defending territory. Biotic and abiotic factors may influence sprint speed in lizards. Temperature decreases at higher altitude.

Earlier winter/spring runoff and snowmelt during warmer winters lead to lower summer chlorophyll-a in north temperate lakes.

Winter conditions, such as ice cover and snow accumulation, are changing rapidly at northern latitudes and can have important implications for lake processes. For example, snowmelt in the watershed-a defining feature of lake hydrology because it delivers a large portion of annual nutrient inputs-is becoming earlier. Consequently, earlier and a shorter duration of snowmelt are expected to affect annual phytoplankton biomass.

Biologically normal sleep in the mother-infant dyad.

Objectives: We examine infant sleep from evolutionary, historico-cultural, and statistical/epidemiological perspectives and explore the distinct conceptions of "normal" produced by each. We use data from the "Sleeping Like a Baby" study to illustrate how these perspectives influence the ideals and practices of new parents.

Methods: The "Sleeping Like a Baby" study investigated maternal-infant sleep in north-east England.

Converting spent lithium cobalt oxide battery cathode materials into high-value products via a mechanochemical extraction and thermal reduction route.

This study innovatively combines mechanochemistry and high-temperature thermal reduction to achieve the recovery of valuable metals from spent LIBs. First, under the action of mechanical force, the crystal structure of lithium cobalt oxide (LiCoO) found in the cathode materials of spent LIBs was destroyed and converted into lithium carbonate (LiCO) and Li-free residue (C/CoO) using dry ice as a co-grinding reagent. The optimum LiCO recovery conditions were determined to be as follows: a ratio of dry ice: LiCoO powder mass of 20:1; a rotation speed of 700 rpm, and a reaction time of 1.

Recent Partner Violence, Sexual Relationship Power, and STIs among Women Who Use Methamphetamine: Does Type of Sexual Partner Matter?

Methamphetamine use, sexual relationship power (SRP), and partner violence (PV) are associated with increased risk of sexually transmitted infections (STIs) among women. The objective of our study was to examine the association of recent PV and SRP on STIs by partner type among HIV-negative, heterosexual women who use methamphetamine in San Diego, CA. Using baseline survey data from 209 women enrolled in FASTLANE II, an HIV behavioral intervention trial, we conducted logistic regression analyses to examine associations between PV, SRP, and self-reported lifetime STIs (e.

High Prevalence of the Copepod in Steelhead Trout in Lake Ontario Following its Recent Invasion.

(Dana, 1853) (Subclass Copepoda: Family Lernaeopodidae) is known to parasitize salmonids of the genus including (rainbow trout), (chinook salmon), and (coho salmon). These 3 salmonids have been introduced to the Great Lakes intermittently since the mid-1800s. As we demonstrate here, the introduction of these salmonids to the Great Lakes was followed, at some point, by the introduction of their parasitic gill copepod, .

Patterns and trends of fish mercury in New York State.

In the mid-2000s a survey was conducted to evaluate fish mercury in lakes across New York State. Approximately 10 years later a second survey examining adult sportfish from 103 lakes and reservoirs was conducted to evaluate the response of fish mercury to recent declines in US mercury emissions. Of those lakes, 43 were part of the earlier survey and were examined to determine if mercury concentrations in four popular sport species, Yellow Perch, Walleye, and Small- and Largemouth Bass, declined in response to decreasing emissions.

Hypoxia by Altitude and Welfare of Captive Beaded Lizards () in Mexico: Hematological Approaches.

 is one of the few known venomous lizards in the world. Their populations are in decline due to habitat destruction and capture for the pet trade. In México, many zoos have decided to take care of this species, most of them at altitudes greater than the natural altitudinal distribution.

Toxicity of Potassium Chloride Compared to Sodium Chloride for Zebra Mussel Decontamination.

The use of chemicals to decontaminate watercraft and/or equipment after exposure to zebra mussels Dreissena polymorpha is one method of decontamination that has been recommended by multiple government agencies in the United States. The ideal chemical to be used for decontamination would be inexpensive and easily obtained, would have no or limited effect on nontarget species, and would be relatively environmentally friendly. Two chemicals that have been tested are potassium chloride (KCl) and sodium chloride (NaCl).

Cranial measures and ancient DNA both show greater similarity of Neandertals to recent modern Eurasians than to recent modern sub-Saharan Africans.

Objectives: Ancient DNA analysis has shown that present-day humans of Eurasian ancestry are more similar to Neandertals than are present-day humans of sub-Saharan African ancestry, reflecting interbreeding after modern humans first left Africa. We use craniometric data to test the hypothesis that the crania of recent modern humans show the same pattern.

Materials And Methods: We computed Mahalanobis squared distances between a published Neandertal centroid based on 37 craniometric traits and each of 2,413 recent modern humans from the Howells global data set (N = 373 sub-Saharan Africans, N = 2,040 individuals of Eurasian descent).

Comparison of observed and expected levels of genetic diversity based on surname frequencies: An example from historical Massachusetts.

Objectives: The inverse of random inbreeding based on surname frequencies (1/F ) is an estimate of genetic diversity, and its expectation is a function of the number of migrants into a population. Observed and expected values of (1/F ) were compared to determine if observed diversity matches theoretical expectations under conditions of rapid demographic change using data from historical Massachusetts.

Materials And Methods: Data on migration and surnames were taken from 6,038 marriage records from the eighteenth and nineteenth centuries from five towns in north-central Massachusetts.

Histopathology of Catostomus commersoni (White Sucker) Infected with the Acanthocephalan Pomphorhynchus bulbocolli.

This study was undertaken to assess the damage caused by Pomphorhynchus bulbocolli to Catostomus commersoni (white sucker). Three specimens of C. commersoni were collected during early September 2014 via gill net from Canadarago Lake (Otsego County, New York), then dissected and examined for intestinal parasites.

Innovating e-waste management: From macroscopic to microscopic scales.

Waste electrical and electronic equipment (WEEE or e-waste) has become a global problem, due to its potential environmental pollution and human health risk, and its containing valuable resources (e.g., metals, plastics).

Two new and one redescribed species of Acanthobothrium (Cestoda: Onchoproteocephalidea: Onchobothriidae) from Dasyatis akajei (Myliobatiformes: Dasyatidae) in the China Sea.
