Melanoma and Other Melanistic Lesions in Brown Bullhead Ameiurus nebulosus From Waterbodies in the Northeastern United States and Canada: Identification of Risk Factors

Journal of Fish Diseases, Volume 49, Issue 11, November 2026.
ABSTRACT Melanistic lesions, including non‐raised black areas due to proliferations of melanocytes and melanomacrophages in the dermis and epidermis, as well as raised black areas consistent with melanoma, are described in brown bullhead (BBH) Ameiurus nebulosus from three water bodies in the northeastern United States and Quebec, Canada.

Risk Factors for Pathologic Fracture in Dogs With Confirmed or Suspected Appendicular Osteosarcoma Treated With Low‐ or Standard‐Dose‐Rate Palliative External Beam Radiation Therapy

Veterinary Radiology &Ultrasound, Volume 67, Issue 6, November 2026.
ABSTRACT Pathologic fracture is a complication of bone cancer with probable increased risk following radiation therapy (RT). Low‐dose‐rate (LDR) RT can spare late‐responding normal tissues by allowing intrafraction DNA repair, which could also impact tumor response. This retrospective cohort study evaluated efficacy and fracture rate in canine patients

Local Adaptation With Gene Flow Has a Polygenic Basis in a Threatened Coastal Songbird

Ecology and Evolution, Volume 16, Issue 10, October 2026.
Using a new chromosome‐level reference genome and whole‐genome sequencing, we show that the threatened, coastally specialized Atlantic song sparrow (Melospiza melodia atlantica) maintains adaptive divergence from a widespread generalist subspecies with divergently selected loci scattered across the genome rather than concentrated in low‐recombination ...

The Benefits of Achieving the Chesapeake Bay TMDLs (Total Maximum Daily Loads): A Scoping Study [PDF]

Concerns about nutrient pollution in the Chesapeake Bay have led to the establishment of pollution limits—total maximum daily loads (TMDLs)—which, by 2025, are expected to reduce nitrogen loadings to the Bay by 25 percent and phosphorous loadings by 24 ...

Assessing water clarity in the Chesapeake Bay using satellite-derived Secchi disk depth

International Journal of Applied Earth Observations and Geoinformation
Water clarity is an important characteristic of water quality and ecosystem health in inland and coastal waters. Secchi disk depth (SDD) is a conventional in situ optical method of measuring this parameter.

Seasonality, Storms and Soil Properties Drive Groundwater and Salinity Dynamics in Retreating Coastal Forests

Ecohydrology, Volume 19, Issue 7, October/November 2026.
ABSTRACT Sea level rise is causing the rapid conversion of upland habitats to salt marshes in low‐sloping areas due to increasing groundwater salinity and soil saturation. Despite this being a widespread phenomenon, questions remain about the factors shaping groundwater hydrology and salinity in these transitioning systems, particularly in the US ...

Influence of Wind Strength and Duration on Relative Hypoxia Reductions by Opposite Wind Directions in an Estuary with an Asymmetric Channel

Journal of Marine Science and Engineering, 2016
Computer model experiments are applied to analyze hypoxia reductions for opposing wind directions under various speeds and durations in the north–south oriented, two-layer-circulated Chesapeake estuary.

Variation and Drivers of Water Chemistry in a Low‐Relief Wetlandscape

Hydrological Processes, Volume 40, Issue 10, October 2026.
Dissolved organic carbon, nitrogen, phosphorous, P and NH4+ and concentrations were higher in wetland water than nearby surficial groundwater. Our findings also suggest that seasonal variation in biological activity and hydrological dynamics controlled wetland water chemistry, while groundwater chemistry was primarily governed by saturation of solute ...

Digenetic trematodes of the Chesapeake Bay

Chesapeake Science, 1972
It is safe to say that the taxonomy of Digenea from fishes and invertebrates from Chesapeake Bay is in need of considerable attention. First, the knowledge of what flukes are present is lacking, with the exception of a few scattered papers dealing with a limited number of species. A few such papers about adult Digenea from fishes are by Hopkins (1) and
