An ecological pyramid is a graphical representation designed to show the biomass or bio-productivity at each trophic level in a given ecosystem. there are three types of pyramid- 1) Pyramid of number.2) Pyramid of biomass 3) Pyramid of energy.
Strong variance at decadal and multidecadal timescales is a common feature of most tree-ring width records. But does this aspect of tree growth exhibit such long-memory behavior due to biology, climate, or some combination of the two factors? Understanding the origins of this behavior is crucial for efforts to evaluate the causes of decadal variability in the climate system.

Solar ghosts: Weighing the evidence for sunspot cycles in fossil treesScott St. George
In their study of tree rings from the Chemnitz Fossil Forest (Germany), Luthardt and Rößler (2017) claim to identify a regular near-11-yr cyclicity in growth, and present that pattern as evidence of the influence of the Schwabe solar cycle (Usokin and Mursula, 2003) on climate and forest productivity during the early Permian. If correctly interpreted, these fossil tree rings would indicate the sunspot cycle was the dominant influence on interannual variability in Earth’s climate during this period and that it has been a consistent aspect of our Sun’s behavior for at least the past 300 m.y. We argue the fossil tree-ring record from Chemnitz does not constitute reliable evidence of solar activity during the Permian because the individual tree-ring sequences are not correctly aligned (dendrochronologically dated) and, as a result, the mean ring-width composite is not a meaningful estimate of year-to-year variations in tree growth in this ancient forest.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

1. A first look at temporal change among Lau Basin megafauna June 2006—June 2009 Arunima Sen a , Elizabeth L. Podowski a , Erin L. Becker a , George W. Luther III b and Charles R. Fisher a a Biology Department, Pennsylvania State University, 208 Mueller Building, University Park, PA 16802 b College of Marine and Earth Studies, University of Delaware, 700 Pilottown Road, Lewes, DE 19958 Early observations of the three foundation Lau megafauna, Alviniconcha hessleri, Ifrermeria nautliei and Bathymodiolus brevior indicated differentiation on a spatial scale. We combined high resolution imagery with in-situ physico-chemical measurements to tease apart species specific tolerances to temperature, oxygen concentration and sulphide concentrations. Based on these studies, we hypothesized temporal change and succession and both chimney and diffuse flow sites. Alviniconcha hessleri Highest temperature, Highest sulfide Lowest oxygen Ifremeria nautilei Medium temperature Medium sulfide Medium oxygen Bathymodiolus brevior Lowest temperature Lowest sulfide Highest oxygen Spatial Differentiation of Lau megafauna Change in Diffuse Flow Sites Stability of Chimneys We returned to 7 diffuse flow sites in June 2009 for re-imaging and electrochemical measurements. We found both examples of more active and less active sites, giving us a glimpse of successional patterns in different directions. The following examples illustrate our findings. Unlike diffuse flow sites, chimneys displayed much more stability and less change over time. While diffuse flow sites are undergoing a process of replacement linked to changing flow regimes, chimneys communities displayed little difference in the past four years. Kilo Moana Site 1, 2006 Kilo Moana Site 1, 2009 This site is an example of an area becoming less active. Note the larger numbers of dead mussels, fewer anemones and the appearance of non vent endemic brisingids in the 2009 mosaic. The graphs show that the site is dying. ABE Site 2, 2006 Kilo Moana 2: Example of less active site ABE 2: Example of more active site Bugs Bunny, 2006 Tu’i Malila 62, 2006 Note the lack of change in fauna between the two years. At the Tu’i chimney, the chemistry has remained the same, whereas at Bugs Bunny, the chemistry has reversed. This indicates that faunal changes at chimneys is slow despite flow regime changes. Future Questions Acknowledgements Bugs Bunny, 2009 ABE Site 2, 2009 This is an example of a site undergoing succession. The graphs show little chemical difference, but note the lack of anemones and the higher dominance of B. brevior in the 2009 mosaic. Pioneering species--- Intermediate species--- Climax species This is a preliminary look at succession and temporal change among Lau Basin megafauna. Further analyses within a GIS framework will be conducted to quantify both faunal and chemical change at these sites. In addition to diffuse flow and chimney sites, we have collected data for peripheral sites which will further contribute to our understanding of temporal change of Lau megafauna.
