Habitat fragmentation is a key driver of reduced genetic connectivity and loss of genetic variation among populations, elevating the risk of inbreeding depression and reduced adaptive potential. The black-throated finch ( Poephila cincta ) is an endemic Australian finch with two recognised subspecies, a northern ( P. c. atropygialis ) and southern form ( P. c. cincta ) separated by a biogeographic barrier in northern Australia...
Animals regularly experience periods of food uncertainty due to seasonal changes and environmental variability. Further, the changing climate is leading to more variable weather patterns, which alter environmental conditions, and can result in resource distributions being less predictable in space and time. How animals respond to uncertain conditions, and in particular a changing distribution of food resources, remains largely...
Effects of maternal arsenic exposure on birth outcomes using harmonized data across three birth cohortsNARA Subscribed
Objectives To assess the association between urinary arsenic concentrations and birth outcomes by harmonizing data from three independent birth cohorts. Methods We harmonized and analyzed data from the Navajo Birth Cohort Study (NBCS), the New Hampshire Birth Cohort Study (NHBCS), and the PROTECT Center study based on Puerto Rico. Birth outcomes of interest included birth weight, head circumference, birth length, gestational a...
Implications of the first recording of European silver eels Anguilla anguilla in the inland waters of CyprusNARA Subscribed
Migrating silver European eels Anguilla anguilla are reported from the inland waters of the island of Cyprus for the first time, expanding the known geographic range in the Eastern Mediterranean of emigrating adults of this critically endangered, catadromous species. Silver eels were captured attempting to migrate to sea from two separate locations. This is important, as Cyprus was previously exempt from European eel managemen...
Neurobiology of co-morbid stress and a western diet in mice: mitochondrial, proteomic and behavioral outcomesNARA Subscribed
Chronic stress (CS) and hyper-caloric diets promote affective disorders, however pathobiological interactions await definition. Neurobiological and behavioral influences of chronic stress (CS; 2 h/day restraint for 2 wks) were studied in male C57Bl/6 mice fed a control diet (CD; 12% kcal as fat/65% carbohydrate/23% protein) or Western diet (WD; 32% kcal fat/57% carbohydrate/11% protein) for 20 wks. CS induced weight loss and a...
Native trees are related to advanced bird breeding phenology and increased reproductive success along an urban gradientNARA Subscribed
Urban areas are altered from natural landscapes in several ways that can impact wildlife. Birds are widespread in urban areas, and it is well documented that there are phenotypic differences between urban and non‐urban conspecifics. However, little is known about which characteristics of the urban environment are driving differences. We used 9 years of data from nest boxes spread across 20 sites along a 40‐km urban–non‐urban g...
Overlooked seasonal groundwater nutrient fluxes rival anthropogenic point sources across a variable land‐use tidal riverNARA Subscribed
Understanding groundwater–surface water connectivity in tidal freshwater zones is essential for managing ecosystems within the riverine–estuarine continuum. Groundwater discharge is a key source of dissolved nutrient loads that can lead to eutrophication, deoxygenation, and other ecosystem imbalances in coastal environments. However, groundwater is an often‐overlooked nutrient delivery pathway, with limited studies quantifying...
