Abstract
Data resulting from environmental monitoring programs are valuable assets for natural resource managers, decision-makers, and researchers. These data are often collected to inform specific reporting needs or decisions with a specific timeframe. While program-oriented data and related publications are effective for meeting program goals, sharing well-documented data and metadata allows users to research aspects outside initial program intentions. As part of an effort to integrate data from four long-term large-scale US aquatic monitoring programs, we evaluated the original datasets against the FAIR (Findable, Accessible, Interoperable, Reusable) data principles and offer recommendations and lessons learned. Differences in data governance across these programs resulted in considerable effort to access and reuse the original datasets. Requirements, guidance, and resources available to support data publishing and documentation are inconsistent across agencies and monitoring programs, resulting in various data formats and storage locations that are not easily found, accessed, or reused. Making monitoring data FAIR will reduce barriers to data discovery and reuse. Programs are continuously striving to improve data management, data products, and metadata; however, provision of related tools, consistent guidelines and standards, and more resources to do this work is needed. Given the value of these data and the significant effort required to access and reuse them, actions and steps intended on improving data documentation and accessibility are described.

Abstract
Management actions intended to benefit fish in large rivers can directly or indirectly affect multiple ecosystem components. Without consideration of the effects of management on non-target ecosystem components, unintended consequences may limit management efficacy. Monitoring can help clarify the effects of management actions, including on non-target ecosystem components, but only if data are collected to characterize key ecosystem processes that could affect the outcome. Scientists from across the U.S. convened to develop a conceptual model that would help identify monitoring information needed to better understand how natural and anthropogenic factors affect large river fishes. We applied the conceptual model to case studies in four large U.S. rivers. The application of the conceptual model indicates the model is flexible and relevant to large rivers in different geographic settings and with different management challenges. By visualizing how natural and anthropogenic drivers directly or indirectly affect cascading ecosystem tiers, our model identified critical information gaps and uncertainties that, if resolved, could inform how to best meet management objectives. Despite large differences in the physical and ecological contexts of the river systems, the case studies also demonstrated substantial commonalities in the data needed to better understand how stressors affect fish in these systems. For example, in most systems information on river discharge and water temperature were needed and available. Conversely, information regarding trophic relationships and the habitat requirements of larval fishes were generally lacking. This result suggests that there is a need to better understand a set of common factors across large-river systems. We provide a stepwise procedure to facilitate the application of our conceptual model to other river systems and management goals.

Abstract
Understanding trends in the diverse resources provided by large rivers will help balance tradeoffs among stakeholders and inform strategies to mitigate the effects of landscape scale stressors such as climate change and invasive species. Absent a cohesive coordinated effort to assess trends in important large river resources, a logical starting point is to assess our ability to draw inferences from existing efforts. In this paper, we use a common analytical framework to analyze data from five disparate fish monitoring programs to better understand the nature of spatial and temporal trends in large river fish assemblages. We evaluated data from programs that monitor fishes in the Colorado, Columbia, Illinois, Mississippi, and Tallapoosa rivers using non-metric dimensional scaling ordinations and associated tests to evaluate trends in fish assemblage structure and native fish biodiversity. Our results indicate that fish assemblages exhibited significant spatial and temporal trends in all five of the rivers. We also document native species diversity trends that were variable within and between rivers and generally more evident in rivers with higher species richness and programs of longer duration. We discuss shared and basin-specific landscape level stressors. Having a basic understanding of the nature and extent of trends in fish assemblages is a necessary first step towards understanding factors affecting biodiversity and fisheries in large rivers.

Abstract
We documented changes in plasma levels of estradiol 17-beta (E2), progesterone (P), 15alpha-hydroxytestosterone (15alpha-T), thyroxine (T4), triiodothyronine (T3), protein, triglycerides (TGs), and glucose in adult Pacific lampreys (Entosphenus tridentatus) held in the laboratory in two different years. Levels of E2 in both sexes ranged from 0.5 to 2 ng/mL from September to March, peaked in late April (2-4 ng/mL), and decreased in May, with levels higher in males than in females. Levels of P were low from September through April, but then increased substantially during May (2-4 ng/mL), with levels again highest in males. Levels of 15alpha-T in males were around 0.75 ng/mL through the winter before exceeding 1 ng/mL in April and decreasing thereafter, whereas females showed a gradual increase from 0.25 ng/mL in November to 0.5 ng/mL in April before decreasing. Thyroxine concentrations differed between fish in each year, with most having levels ranging from 0.75 to 2.5 ng/mL in the fall and winter, and only fish in 2003 showing distinct peaks (3-4 ng/mL) in early April or May. Plasma T3 was undetectable from November through mid-March before surging dramatically in April (ca. 150 ng/mL) and decreasing thereafter. Levels of protein, TGs, and glucose decreased or were stable during the fall and winter with TGs and glucose surging in late April to early May for some fish. Our study is the first to document long-term physiological changes in Pacific lampreys during overwintering and sexual maturation and increases our understanding of the life history of this unique fish.

Abstract
The effectiveness of morphometric and meristic characteristics for taxonomic discrimination of Lampetra tridentata and L. richardsoni (Petromyzonidae) during embryological, prolarval, and early larval stages (i.e., age class 1) were examined. Mean chorion diameter increased with time from fertilization to hatch and was significantly greater for L. tridentata than for L. richardsoni at 1, 8, and 15 days postfertilization. Lampetra tridentata larvae had significantly more trunk myomeres than L. richardsoni; however, trunk myomere numbers were highly variable within species and deviated from previously published data. Multivariate examinations of prolarval and larval L. tridentata (7.2-11.0 mm; standard length) and L. richardsoni (6.6-10.8 mm) were conducted based on standard length and truss element lengths established from eight homologous landmarks. Principal components analysis indicated allometric relationships among the morphometric characteristics examined. Changes in body shape were indicated by groupings of morphometric characteristics associated with body regions (e.g., oral hood, branchial region, trunk region, and tail region). Discriminant function analysis using morphometric characteristics was successful in classifying a large proportion (> 94.7%) of the lampreys sampled.

Abstract
Comparative studies were performed on two native lamprey species, Pacific lamprey (Lampetra tridentata) and western brook lamprey (Lampetra richardsoni) from the Pacific coast along with sea lamprey (Petromyzon marinus) from the Great Lakes, to investigate their bile acid production and release. HPLC and ELISA analyses of the gall bladders and liver extract revealed that the major bile acid compound from Pacific and western brook larval lampreys was petromyzonol sulfate (PZS), previously identified as a migratory pheromone in larval sea lamprey. An ELISA for PZS has been developed in a working range of 20 pg-10 ng per well. The tissue concentrations of PZS in gall bladder were 127.40, 145.86, and 276.96 micro g/g body mass in sea lamprey, Pacific lamprey, and western brook lamprey, respectively. Releasing rates for PZS in the three species were measured using ELISA to find that western brook and sea lamprey released PZS 20 times higher than Pacific lamprey did. Further studies are required to determine whether PZS is a chemical cue in Pacific and western brook lampreys.

Abstract
Slices of an adreno-cortical adenoma which had been obtained at operation from an 11-year-old girl with clinical signs of virilism were incubated with each of the following steroids: [1,2-3H]progesterone, [4-14C]pregnenolone, [1,2-3H]testosterone, [4-14C]androstenedione and [7-3H]dehydroepiandrosterone, respectively. Isolation and identification of the free radioactive metabolites were achieved by gel column chromatography on Sephadex LH-20, thin-layer chromatography, radio gas chromatography and isotope dilution. After incubation of progesterone, the following metabolites were identified: 11beta-hydroxyprogesterone, 16alpha-hydroxyprogesterone, 17alpha-hydroxyprogesterone, 21-deoxycortisol, corticosterone and cortisol. Pregnenolone was metabolized to 17alpha-hydroxypregnenolone, progesterone, dehydroepiandrosterone, androstenedione and 11beta-hydroxyandrostenedione. When testosterone was used as substrate, 11beta-hydroxytestosterone, androstenedione and 11beta-hydroxyandrostenedione were found as metabolites, whereas androstenedione was metabolized to testosterone and 11beta-hydroxyandrostenedione. After incubation of dehydroepiandrosterone, only androstenedione and 11beta-hydroxyandrostenedione were isolated and identified. From these results, it appears that cortisol was formed in the adenoma tissue via 21-deoxycortisol and corticosterone. Delta4-3oxo steroids of the C19-series arose exclusively from pregnenolone via 17alpha-hydroxypregnenolone and dehydroepiandrosterone, and not from progesterone and 17alpha-hydroxyprogesterone. Calculated on the amounts of metabolites formed, the highest enzyme activities were those of the 11beta-hydroxylase and the 17alpha-hydroxylase. It is interesting to note that only traces of testosterone were detected after incubation of androstenedione, whereas testosterone yielded large amounts of androstenedione.

Abstract
As pheochromocytoma sometimes is accompanied by medullary thyroid carcinoma (in the sense of multiple endocrine adonomatosis type II = Sipple-Syndrome), serum calcitonin (CT) was measured by radioimmunoassay in 4 patients with pheochromocytoma. Before extirpation of the adreno-medullary tumor, serum CT was distinctly increased to 3 and 30 ng/ml in 2 of 4 patients, respectively. After removal of the tumor, serum CT was normal in the patients and pentagastrin stimulation produced no exaggerated CT response. In hydrochloric acid extracts from the two corresponding pheochromocytoma tissues, immunoreactive-Calcitonin (IR-CT) was detected, the concentrations amounting 1 and 4 ng/mg wet tissue. These findings suggest that hypercalcitonism in patients with pheochromocytoma cannot always be ascribed to the thyroid, i.e. increased calcitonin levels do not necessarily indicate a medullary carcinoma of this organ.

Abstract
The biogenesis of C19- and C21-steroids has been studied in tissue slices of a paraganglioma, of a pheochromocytoma and of human adrenal cortex using radioactive steroids. Slices of paraganglioma as well as of pheochromocytoma metabolise 17-hydroxyprogesterone to cortisone, cortisol, 11-deoxycortisol and testosterone. The rate of formation of these steroids, however, by the two tumours is 8--15 times less than that in normal adrenal cortex tissue. After incubation of dehydroepiandrosterone with tissue slices of paraganglioma and pheochromocytoma, 7alpha-hydroxydehydroepiandrosterone, 11beta-hydroxy-4-androstene-3,17-dione and 4-androstene-3,17-dione were found as metabolites; testosterone was converted by both tissues to 4-androstene-3,17-dione. 17-Hydroxypregnenolone was converted to a small extent (1.7%) to dehydroepiandrosterone by slices of paranganglioma. These results show that enzymes of steroid biosynthesis (hydroxylases, oxidoreductases, delta4(-5)-isomerases, C17(-20)-desmolases) are present in both paraganglioma and pheochromocytoma.

Abstract
Short-term fluctuations in plasma cortisol were determined overnight in twelve patients with Cushing's syndrome: eight patients with bilateral adrenal hyperplasia of hypothalamic-pituitary orgin, three patients with a cortisol producing adenoma and one patient with a carcinoma of the adrenal cortex. While either secretory episodes in plasma cortisol or a fixed pattern of cortisol secretion were observed both in patients with pituitary dependent and in those with pituitary independent hypercorticism, a typical night-day variation in plasma cortisol was only found in one of the eight patients with Cushing's syndrome of hypothalamic-pituitary origin. The patient with a cortisol producing carcinoma showed only minor fluctuations in plasma cortisol throughout the test period. The results indicate that no discrimination can be made between patients with pituitary dependent or independent Cushing's syndrome by demonstrating an episodic or a fixed secretion of cortisol. It seems, however, that the finding of a typical night-day variation in hormone secretion points to hypercorticism of hypothalamic-pituitary orgin.

Abstract
Patients suffering from pheochromocytoma characterized by an exclusive or almost exclusive excess of norepinephrine showed no (one patient) or only a moderate increase (two patients) in renin and aldosterone secretion. In those three patients with concomitant distinct hypersecretion of epinephrine, renin release (and aldosterone secretion except in one patient) was markedly enhanced. Similar results were obtained in a patient with excess norepinephrine and dopamine secretion. Renin release was markedly reduced in all patients during preoperative long-term alpha-adrenergic receptor blockade. With the exception of one patient, increased renin and aldosterone secretion was abolished. The results indicate that augmentation in renin release depends on the ratio of the different catecholamines secreted by the pheochromocytoma and their different effe-tiveness in stimulating beta-adrenergic receptors. Even in the presence of excess catecholamine secretion, there is evidence that renin secretion is predominantly mediated by beta receptors rather than by renal vascular alpha-adrenergic receptors. Normalization of catecholamine-induced enhanced renin release in patients with pheochromocytoma during chronic alpha-adrenergic receptor blockade supports the assumption that (alpha-) adrenergic blocking agents inhibit renin secretion distal to their blockade of specific adrenergic receptors. However, contrary to beta-adrenergic blockade, circadian rhythm of renin release seems to remain intact during alpha-adrenergic blockade.
