Effects of hard water precipitates on early life stage brook trout Effects of hard water precipitates on early life stage brook trout
Brook trout (Salvelinus fontinalis) have been extirpated from many karst-geology streams in West Virginia; however, the causes are not fully understood. Specifically, the impact of calcareous precipitate (marl), which is common in hard-water environments, has not been evaluated as an impediment to juvenile survival. Accordingly, two lab-based studies were conducted to determine if brook...

Beyond simple trend tests: Detecting significant changes in design-flood quantiles Beyond simple trend tests: Detecting significant changes in design-flood quantiles
Changes in annual maximum flood (AMF), which are usually detected using simple trend tests (e.g., Mann-Kendall test (MKT)), are expected to change design-flood estimates. We propose an alternate framework to detect significant changes in design-flood between two periods and evaluate it for synthetically generated AMF from the Log-Pearson Type-3 (LP3) distribution due to changes in...

White perch health relative to urbanization and habitat degradation in Chesapeake Bay tributaries. I. Biliary neoplasms and hepatic lesions White perch health relative to urbanization and habitat degradation in Chesapeake Bay tributaries. I. Biliary neoplasms and hepatic lesions
White perch Morone americana (Gmelin, 1789) from the Chesapeake Bay (USA) watershed have a high incidence of liver disease, including neoplasms of bile duct origin. Fish collected seasonally from spring 2019 to winter 2020 from the urban Severn River and the more rural Choptank River were evaluated for hepatic lesions. Biliary hyperplasia (64.1%), neoplasms (cholangioma and...

Refining capture-recapture recruitment estimation methods for Atlantic sturgeon Refining capture-recapture recruitment estimation methods for Atlantic sturgeon
The Atlantic sturgeon Acipenser oxyrinchus oxyrinchus was once of great commercial importance in many coastal rivers of the eastern USA. Over the 19th and 20th centuries, most historical stocks of Atlantic sturgeon were depleted by human activities. Estimating recruitment for the remaining populations is challenging due to sampling constraints, limited age data, and natural variability...

The Factors Affecting Female Black Bear Harvest Rates in Pennsylvania The Factors Affecting Female Black Bear Harvest Rates in Pennsylvania
Pennsylvania’s black bear (Ursus americanus) population increased in abundance and distribution during the latter third of the 20th century, leading to an increase in human-bear conflicts. Increases in harvest opportunities from 2002–2018 aimed to stabilize black bear population growth but did not substantially increase harvest, and annual harvest was often below the desired goal of 20%...

Evolution of a minimal cell Evolution of a minimal cell
Possessing only essential genes, a minimal cell can reveal mechanisms and processes that are critical for the persistence and stability of life1,2. Here we report on how an engineered minimal cell3,4 contends with the forces of evolution compared with the Mycoplasma mycoides non-minimal cell from which it was synthetically derived. Mutation rates were the highest among all reported...

SARS-CoV-2 utilization of ACE2 from different bat species allows for virus entry and replication in vitro SARS-CoV-2 utilization of ACE2 from different bat species allows for virus entry and replication in vitro
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is believed to have a zoonotic origin with bats suspected as a natural host. In this work, we individually express the ACE2 of seven bat species including, little brown, great roundleaf, Pearson's horseshoe, greater horseshoe, Brazilian free-tailed, Egyptian rousette, and Chinese rufous horseshoe in DF1 cells and determine...

Identifying invertebrate indicators for streamflow duration assessments in forested headwater streams Identifying invertebrate indicators for streamflow duration assessments in forested headwater streams
Streamflow-duration assessment methods (SDAMs) are rapid, indicator-based tools for classifying streamflow duration (e.g., intermittent vs perennial flow) at the reach scale. Indicators are easily assessed stream properties used as surrogates of flow duration, which is too resource intensive to measure directly for many reaches. Invertebrates are commonly used as SDAM indicators because...

Estimating proximity effects to wildfire fuels treatments on house prices in Cibola National Forest, New Mexico, USA Estimating proximity effects to wildfire fuels treatments on house prices in Cibola National Forest, New Mexico, USA
Forested landscapes in the Western United States are subject to growing size and severity of wildfires, in part due to historical management strategies focusing on wildfire suppression. Forest restoration treatments and fuels reductions, including thinning and prescribed burning, can reduce the frequency and intensity of wildfires. Extensive restoration and fuels treatment efforts are...

Global assessment of marine plastic exposure for oceanic birds Global assessment of marine plastic exposure for oceanic birds
Plastic pollution is distributed patchily around the world’s oceans. Likewise, marine organisms that are vulnerable to plastic ingestion or entanglement have uneven distributions. Understanding where wildlife encounters plastic is crucial for targeting research and mitigation. Oceanic seabirds, particularly petrels, frequently ingest plastic, are highly threatened, and cover vast...

Seasonal habitat utilization provides evidence for site fidelity during both spawn and non-spawning seasons in Lake Ontario cisco Coregonus artedi Seasonal habitat utilization provides evidence for site fidelity during both spawn and non-spawning seasons in Lake Ontario cisco Coregonus artedi
The Lake Ontario cisco Coregonus artedi population declined in the 20th century, and restoration of this species is a management objective. Management tools to restore cisco are limited because little is known about cisco spawning behavior and habitat use. We tagged 76 cisco from a remnant population in Chaumont Bay, Lake Ontario with acoustic transmitters and characterized seasonal...

Structure of breeding calls in three closely related bird species (Calidris Merrem, 1804; Scolopacidae) Structure of breeding calls in three closely related bird species (Calidris Merrem, 1804; Scolopacidae)
We studied calls of three sandpiper species to document species’ similarities and differences. We hypothesized that functionally different calls would differ in degree of divergence. We studied two nuptial calls (complex “Song” and rhythmically repeated aerial call, RRC) of males, and a general-purpose call (“alarm” trill, AT) given by parents of both sexes in the presence of humans and...
