Northern Pakistan is interpreted here as including three administrative regions: Khyber Pakhtunkhwa, Gilgit-Baltistan, and Azad Jammu and Kashmir. It is dominated by multiple mountain ranges whose valleys drain, directly or indirectly, into the Indus River. Hazara University, which is in Khyber Pakhtunkhwa, was started in 2002 and its herbarium (HUP) in 2005. Digitization of the herbarium's vascular plants began in 2021 with its records being shared in OpenHerbarium and GBIF. Its online presence is now growing more rapidly than any other Pakistani herbarium. This paper summarizes the taxonomic diversity and geographic origin of its monocot holdings in 2023. In 2023, …

The purpose of this study was to determine if the thermal tolerance and physiology of the coqui frog changed along HawaiÔiÕs elevation gradient. A short acclimation experiment was used to test the baseline thermal tolerance and physiology, and an extended acclimation experiment to test the acclimation ability of the thermal tolerance and physiology metrics of the coqui frogs collected from low (m), medium (350-550 m) and high elevations (>750 m).

The purpose of this study was to determine whether elevation in HawaiÔi affects the coquiÕs microhabitat use such as substrate choice and height off the forest floor and physiological metrics such as osmolality, oxidative status, and energy metabolites (glucose, free glycerol, and triglycerides).
Blood Chemistry And Biliverdin Differ According To Reproduction And Tourism In A Free-Living Lizard, Susannah French
Blood Chemistry And Biliverdin Differ According To Reproduction And Tourism In A Free-Living Lizard, Susannah French

Changes in the physiological health of species are an essential indicator of changing conditions and environmental challenges. Reponses to environmental challenges can often induce stress, influence physiology, and change metabolism in organisms. Here we tested blood chemistry parameters indicative of stress and metabolic activity using an i-STAT point-of-care blood analyzer in seven populations of free-ranging rock iguanas exposed to varying levels of tourism and supplemental feeding. We found significant differences in blood chemistry (glucose, oxygen, carbon dioxide, hematocrit, hemoglobin, calcium, potassium, and biliverdin levels) among populations exposed to varying levels of tourism, and also some variation between sexes and reproductive …

To promote survival and fitness, organisms use a suite of physiological systems to respond to both predictable and unpredictable changes in the environment. These physiological responses are also influenced by changes in life history state. The continued activation of physiological systems stemming from persistent environmental perturbations enable animals to cope with these challenges but may over time lead to significant effects on the health of wildlife. In the present study, we tested how varying environmental perturbations driven by tourism and associated supplemental feeding affects the energetics, corticosterone and immunity of six discrete populations of the northern Bahamian rock iguana (Cyclura …

Physiological responses to both natural and anthropogenic perturbations involve changes in glucose use and metabolism to enable animals to respond to challenges. The responses are at least partially mediated via the glucocorticoids, and the proper functioning of these systems are critical to animal health. Prolonged high-sugar diets in humans can compromise physiological functions and lead to a range of diseases including diabetes. Such outcomes are less common in natural, non-human systems, likely because of evolutionarily based balances between sugar intake and the ability to process it. Due to both landscape changes and human feeding of wildlife, the introduction of unnatural …

Energy Expenditure Across Immune Challenge Severities In A Lizard: Consequences For Innate Immunity, Locomotor Performance And Oxidative Status, Susannah S. French, Spencer Hudson

Reptiles, like other vertebrates, rely on immunity to defend themselves from infection. The energetic cost of an immune response is liable to scale with infection severity, prompting constraints on other selfmaintenance traits if immune prioritization exceeds energy budget. In this study, adult male side-blotched lizards (Uta stansburiana) were injected with saline (control) or high (20 μg g−1 body mass) or low (10 μg g−1 body mass) concentrations of lipopolysaccharide (LPS) to simulate bacterial infections of discrete severities. The costs and consequences of the immune response were assessed through comparisons of change in resting metabolic rate (RMR), energy metabolites (glucose, glycerol, …

Wounding events (predation attempts, competitive combat) result in injuries and/or infections that induce integrated immune responses for the recovery process. Despite the survival benefits of immunity in this context, the costs incurred may require investment to be diverted from traits contributing to immediate and/or future survival, such as locomotor performance and oxidative status. Yet, whether trait constraints manifest likely depends on wound severity and the implications for energy budget. For this study, food intake, body mass, sprint speed, and oxidative indices (reactive oxygen metabolites, antioxidant capacity) were monitored in male side-blotched lizards (Uta stansburiana) healing from cutaneous wounds of discrete …
Glucocorticoids, Energy Metabolites, And Immunity Vary Across Allostatic States For Plateau Side-Blotched Lizards (Uta Stansburiana Uniformis) Residing In A Heterogeneous Thermal Environment, Susannah S. French, Spencer B. Hudson

Reptiles rely on thermal heat exchange to achieve body temperatures (Tbody) conducive to maintaining homeostasis. Diurnal changes in the thermal environment are therefore liable to influence allostatic mediation of survival processes (e.g., immunity) during environmental challenges or stressors. However, the extent to which Tbody prompts individual variation in physiology remains largely unexplored in reptiles. Our study tested how circulating energy-mobilizing hormone, energy metabolites, and immunity can vary across basal and stress-induced allostatic states for plateau side-blotched lizards (Uta stansburiana uniformis) residing in a heterogeneous thermal environment. We collected baseline and acute stress blood samples from male lizards to compare changes …

The hydrophyte Allenrolfea occidentalis (S. Watson) Kuntze (iodine bush) is a halophytic shrub of the arid southwest that is listed as a facultative wetland (FACW) species on the National Wetland Plant List. This rating means the species is usually a hydrophyte but occasionally is found in uplands. We tested for genetic (ecotypic) differences between plants sampled from wetlands versus uplands. We used genotyping-by-sequencing (ddRAD-seq) to generate data from 133 plants from 30 locations representing both wetland and upland occurrences for over 1300 loci. Analyses indicated that the strongest signal is differences in geographic distribution: samples that are in close geographic …

Premise of the study: Until recently, most phylogenetic studies of ferns were based on chloroplast genes. Evolutionary inferences based on these data can be incomplete because the characters are from a single linkage group and are uniparentally inherited. These limitations are particularly acute in studies of hybridization, which is prevalent in ferns; fern hybrids are common and ferns are able to hybridize across highly diverged lineages, up to 60 million years since divergence in one documented case. However, it not yet clear what effect such hybridization has on fern evolution, in part due to a paucity of available biparentally inherited …
