To determine trends in either frog distribution or abundance in the State of Louisiana, we reviewed and analyzed frog call data from the Louisiana Amphibian Monitoring Program (LAMP). The data were collected between 1997 and 2017 using North American Amphibian Monitoring Program protocols. Louisiana was divided into three survey regions for administration and analysis: the Florida Parishes, and 2 areas west of the Florida parishes called North and South. Fifty-four routes were surveyed with over 12,792 stops and 1,066 hours of observation. Observers heard 26 species of the 31 species reported to be in Louisiana. Three of the species not heard were natives with ranges that did not overlap with survey routes. The other two species were introduced species, the Rio Grande Chirping Frog (Eleutherodactylus cystignathoides) and the Cuban Treefrog (Osteopilus septentrionalis). Both seem to be limited to urban areas with little to no route coverage. The 15 most commonly occurring species were examined in detail using the percentage of stops at which they observed along a given survey and their call indices. Most species exhibited a multimodal, concave, or convex pattern of abundance over a 15-year period. Among LAMP survey regions, none of the species had synchronous population trends. Only one group of species, winter callers, regularly co-occur. Based on the species lists, the North region could be seen as a subset of the South. However, based on relative abundance, the North was more similar to Florida parishes for both the winter and summer survey runs. Our analyses demonstrate that long-term monitoring (10 years or more) may be necessary to determine population and occupancy trends, and that frog species may have different local demographic patterns across large geographic areas.

ABSTRACT In November 2005, approximately 1.9 million gallons of Group V slurry oil was released in the western Gulf of Mexico following the allision of the double-hulled tank barge DBL 152 with the submerged remains of a pipeline service platform that collapsed during Hurricane Rita. The released oil was denser than seawater and sank to the bottom. After approximately six weeks of intermittent cleanup using diver-direct pumping, submerged oil recovery operations were suspended by the Unified Command based on the high percentage (50%) of weather-related downtime, as well as indications that recoverable accumulations of oil were dispersing naturally, which further reduced the feasibility of cleanup. However, the responsible party was required to develop and implement a long-term monitoring program (LTMP) to track the fate and transport of the sunken oil and determine the potential need for resuming oil recovery operations once more favorable weather patterns returned in the spring. This paper will present an overview of the approach, methods and results of the long-term monitoring efforts performed over a 14-month period following the incident. Major objectives of the LTMP included tracking the movement and fate of non-recovered submerged oil to assess its extent and continued dispersion; providing advance warning of potential impacts to Gulf Coast shorelines and other sensitive areas; and documenting changes in the oil'S chemical composition and physical properties through time due to weathering processes. Major findings of the LTMP include the dissipation of the main submerged oil field over the course of several months and the discovery, differential behavior and eventual dissipation of a discrete high-concentration oil patch found several miles from the incident location. The importance of long-term monitoring data in the decision-making process to determine both the need for and feasibility of resuming submerged oil recovery operations will be emphasized. Information on the fate and transport characteristics of submerged oil and the adaptation of monitoring techniques to address evolving needs will also be addressed. Both the incident-specific information and the practical lessons-learned are intended to benefit those who may be faced with monitoring submerged oil spills in the future.

AbstractA survey of ice growth and decay processes on a selection of shallow and deep sub-Arctic and Arctic lakes was conducted using radiometrically calibrated ERS-1 SAR images. Time series of radar backscatter data were compiled for selected sites on the lakes during the period of ice cover (September to June) for the years 1991–92 and 1992–93. A variety of lake-ice processes could be observed, and significant changes in backscatter occurred from the time of initial ice formation in autumn until the onset of the spring thaw. Backscatter also varied according to the location and depth of the lakes. The spatial and temporal changes in backscatter were most constant and predictable at the shallow lakes on the North Slope of Alaska. As a consequence, they represent the most promising sites for long-term monitoring and the detection of changes related to global warming and its effects on the polar regions.

The paper analyzes the long-term dynamics of stocks and annual catches of Pacific cod of the Kuril Islands, and also considers the structure of its modern fishery, taking into account the changes that have occurred in the organization of its coastal fishing in recent years. It was shown that the dynamics of commercial biomass of Pacific cod in the Northern and Southern Kuril Islands is comparable to that in 1975-2020 for groups in the southeastern part of the Bering Sea, the Karagin and Olyutor bays, on the shelf of Western Kamchatka, and in south-western Sakhalin. Development of the cod fishery in the North and South Kuril Islands in 1980-2019 went in accordance with the dynamics of stocks, the maximum catches were observed during the period of a high level of abundance of both groups in the 1980s. While the structure of the cod fishery on the shelf of the Northern Kuril Islands to date can be considered established, the development of fishing in the South Kuril Islands in the last two decades went by the gradual replacement of trawl fishing in the winter-spring period with snorkeling in the summer season.

Abstract In this paper, we summarize Ontario’s Long-term Soil Productivity (LTSP) experience focusing on our efforts to forge lasting research partnerships, highlight the approaches we feel were effective in getting emerging science into forest policy within an adaptive management (AM) framework, and describe the future direction of Ontario’s LTSP program as new policy issues are emerging as part of the continuous AM cycle. Fourteen installations were established on nutrient-poor, conifer-dominated sites, considered to be the most sensitive to increased biomass removals. From 1993 to 1995, all sites were clearcut-harvested, with replicated (three reps per site) biomass removal treatments that included: stem only, full-tree, and full-tree + forest floor removal. Routine (every 5 years) measurements have been carried out to track changes in soil carbon and nutrient levels, as well as stand- and individual-tree growth and development metrics and foliar nutrition. The published results from Ontario’s LTSP program, in combination with the North American-wide LTSP synthesis outputs, have suggested that these nutrient-poor, conifer-dominated sites are less sensitive to biomass (nutrient) removals than previously thought. The evidence provided through peer-reviewed publications, conference and workshop presentations, and field tours was substantive and led to a review and revision of the full-tree logging direction within Ontario’s guidelines. We conclude with a set of recommendations (lessons learned) for the successful delivery of any new long-term, interdisciplinary research projects examining the sustainability of forest-management practices.

This treatise outlines developments in disaster management focusing on earthquake disaster measures taken by the Japanese and Tokyo Metropolitan Governments since the 1980s. The 1978 Large-Scale Earthquake Measures Special Act on conditions for predicting the Tokai Earthquake significantly changed the direction of earthquake disaster measures in Japan. The Tokyo Metropolitan Government undertook its own earthquake disaster measures based on lessons learned from the 1964 Niigata Earthquake. In the 1980s, it began planning urban development disaster management programs for upgrading areas with high wooden houses concentration - still a big problem in many urban areas of Japan - which are most vulnerable to earthquake disasters. The 1995 Great Hanshin-Awaji Earthquake in Kobe brought meaningful insight into both to earthquake disaster measures by the Japanese Government and by the Tokyo Metropolitan Government and other local governments nationwide. Long-term predictions concerning possible earthquake occurrence have been conducted throughout Japan and new earthquake disaster measures have been adopted based on this long-term prediction. The Tokyo Government has further completely revised its own earthquake disaster measures. As a review of measures against foreseeable earthquake disasters based on developments in disaster management measures, this treatise provides invaluable insights emphasizing urban earthquake disaster prevention developed in Japan over the last 30 years that readers are sure to find both interesting and informative in their own work.

The use of substitute groups in biomonitoring programs has been proposed to minimize the high financial costs and time for samples processing. The objectives of this study were to evaluate the correlation between (i) the spatial distribution among the major zooplankton groups (cladocerans, copepods, rotifers, and testaceans protozoa), (ii) the data of density and presence/absence of species, and (iii) the data of species, genera, and families from samples collected in the Lago Grande do Curuai, Pará, Brazil. A total of 55 sample of the zooplanktonic community was collected, with 28 samples obtained in March and 27 in September, 2013. The agreement between the different sets of data was assessed using Mantel and Procrustes tests. Our results indicated high correlations between genus level and species level and high correlations between presence/absence of species and abundance, regardless of the seasonal period. These results suggest that zooplankton community could be incorporated in a long-term monitoring program at relatively low financial and time costs.
