日時：3月19日（水） 13：30~16：20 会場：D201室 ・講演1（13：30～14：30） 演者：Samuel R.P-J. Ross, Okinawa Institute of Science and Technology Graduate University 題目：Microphones, models, and mesocosms for understanding ecological stability across scales 要旨：Understanding the biological processes that promote the invariable and resilient ecosystem services on which humanity depends has been a core focus of ecology for decades. Using randomly structured community models, Robert May showed that diversity is destabilising, so what then explains the vast biodiversity we observe in the real world? There have been many answers from different study systems, often resulting in the classical ecological observation: “it depends”. To distil general understanding from a sea of idiosyncrasy, we need to consider a variety of systems and scales. Here, I present experiments using freshwater mesocosms (buckets), data collected on typhoon disturbance in the field using passive acoustic monitoring (microphones), and models of “response diversity” to describe patterns and drivers of ecological stability across scales. I propose that systems that exhibit a diversity of environmental responses across different organisms (response diversity) or different sites (spatial insurance) should be more stable. Finally, I introduce recent efforts to coordinate international research on the drivers of stability through the nascent Response Diversity Network.
・講演2（14：40～15：20） 演者：Andrea Stephens, Editor-in-Chief, Trends in Ecology & Evolution 題目：Editor’s guide to writing a review article 要旨：With the increasing rates of scientific publications, many researchers are increasingly using reviews to keep themselves updated. As such reviews are valuable resources for the scientific community. But what makes a good review article? In this short talk, I will talk about how this from the perspective of an editor of a reviews journal. We will also discuss some key points regarding getting your review published.

日時：8月9日（金） 15：00～16:00 会場：D101室 講演者：Shunyan Cheung, Assistant Professor, Institute of Marine Biology, National Taiwan Ocean University タイトル：Responses of nitrogen-fixing cyanobacteria in the changing ocean
要旨： Marine nitrogen-fixing cyanobacteria reduce dinitrogen to bioavailable forms of nitrogen, which play critical roles in supporting primary productivity, carbon sequestration and fertility in the ocean. In the context of global climate change, marine nitrogen-fixing cyanobacteria were predicted to be an increasingly important source of nitrogen in the ocean. After decades of research, diverse nitrogen-fixing cyanobacteria have been discovered in the ocean, while our understanding of these organisms remains limited. A comprehensive understanding about the biogeography, ecophysiology and environmental control mechanisms of marine nitrogen-fixing cyanobacteria is essential for a better prediction of the fates of ecosystem and biogeochemical cycling in the future ocean. In this presentation, I will use case studies to demonstrate how we study the impacts of global change stressors on the marine nitrogen-fixing cyanobacteria in field and laboratory. I will also introduce our on-going projects about the nitrogen-fixing cyanobacteria in the Kuroshio east of Taiwan and the vast North Pacific Ocean.

講演タイトル（Talk title）: Challenges to Sustainable Development and Livelihoods in and Around the Water Towers
要旨（Talk summary）:
Kyrgyzstan and Tajikistan rank among the most mountainous nations worldwide, both with more than 90% of the land area in mountains. The Pamir with the highest peak in the region (7495 m a.s.l.) are the dominant mountains in Tajikistan and the Tien Shan (up to 7439 m a.s.l.) occupy much of Kyrgyzstan. These mountains bound the vast Fergana Valley that extends from southern Kyrgyzstan into Uzbekistan and contains unstable hills along the valley fringes with deep loess deposits presenting unique mass wasting challenges. Due to the complex orography, Central Asia has a very dynamic and spatially variable climate that affects water delivery from the Water Towers to streams that provide irrigation supplies during the dry summer months. Water is critical to support food production; runoff is supplied to upland valleys by a combination of snowmelt, glacial melt, and permafrost thaw, together with periodic rainfall. Spring and summer discharge is derived mostly from snowmelt with a lesser amount from glacier melt depending on the extent of glaciation in particular catchments. The interannual variability in snow water poses the greatest challenge for irrigation and domestic supplies, as well as hydropower production.
These mountain areas represent some of the most formidable challenges worldwide in dealing with natural hazard risks and adapting to climate change and anomalies. Hazards that frequently affect mountain communities and their agrarian livelihoods include landslides, debris flows, snow avalanches, rockfall, drought, severe erosion, and flooding; these can be exacerbated by human activities, such as overgrazing, poorly located roads and trails, fuelwood gathering in dry alpine regions, poorly located villages and farms, and unsustainable farming practices. Less frequent hazards include potentially disastrous glacial lake outburst floods (GLOFs) and permafrost hazards.
To characterize climate trends affecting water supplies, glacier melt, and food security, we used remotely sensed precipitation and temperature data due to the sparse network of climate stations. In the Pamir, most areas are experiencing a warming trend, but not at the same rate. Temperatures increased across the east-central Panj and eastern Vakhsh River basins. Warmer temperatures in central Panj basin and the Wakhan corridor coupled with minor declines in snow water will likely induce water stress in local communities during dry years. In contrast, more stable temperatures in lower elevations of western Panj and Vakhsh basins together with increasing precipitation, especially in spring, will benefit agriculture and community water supplies. Varying spatial and temporal patterns of rain and snowfall occur throughout the region, often evident at granular scales. We assessed snow and temperature trends over eight glaciated regions of the Pamir and found diverse tendencies. While most sub-basins experienced some warming, this was offset in some areas by increases in snow. As such, unlike many other high mountain regions, many glaciers of the Pamir are not losing significant mass. Because of high interannual and spatial variability of precipitation throughout the area, regional climate change scenarios cannot inform adaptation measures for mountain communities and other users, and more granular-scale data are needed.

Workshop Title: Structural Equation Modeling (SEM) in R
Structural equation modeling (SEM) is a technique that unites traditional inferential statistics, such as generalized linear modeling, and causal theory to test multivariate hypotheses of cause-and-effect. It translates a simple “box-and-arrow” diagram to a series of mathematical equations, which can be solved to test the magnitude, direction, and significance of causal relationships.
In this short course, I will review the history and philosophy of structural equation modeling and provide a short description of both the “global” and “local estimation” methods. In the afternoon workshop, we will use the software R to apply both methods to an example dataset. I will be available after the workshop to answer specific questions about SEM.
Experience in fitting linear regression (`lm`) in R is required. Please install R (https://cran.r-project.org/) and Rstudio (https://posit.co/downloads/) before the afternoon workshop, if you wish to follow the live coding demonstration.
Schedule:
10:30-12:00 General lecture on piecewise SEM and its application in ecological study
13:00-16:00 Practice of data analyses using piecewise SEM on R

Molecular separation is one of the most energy-intensive industrial processes, primarily due to the inadequate efficacy of current separation methods. This issue becomes critical when it comes to large polymeric compounds. Our group has been focusing on developing new technologies for separating polymers using crystalline nanoporous media, metal–organic frameworks (MOFs). We recently made a discovery that MOFs can adsorb polymers in their nanopores. During the adsorption process, even the slightest differences in polymer structures are recognized, enabling highly precise polymer separation. This has allowed us to distinguish the differences in terminal groups, topology, and even monomer sequences of polymers, which were previously impossible using conventional methods.
We will have an EES seminar on 5/16 at 10:30~12:00 as follows. We look forward to your participation.

講演タイトル（Talk title）: Shorebirds of the Hunter and Port Stephens Estuaries: Using automated telemetry, stable isotopes and e-DNA to quantify movement and food chains in overwintering shorebirds
要旨（Talk summary）: Migratory shorebirds are the world’s most endangered group of bird species. Australia’s estuaries provide overwintering habitat for some 2.5 million individuals each year. The Hunter and Port Stephens estuaries are two of just four in New South Wales of international significance to protecting Australia’s migratory shorebirds. They are also amongst the regions that are losing multiple shorebird species the fastest nationally. Unfortunately, these estuaries have little to no history of shorebird research and critical knowledge gaps are impeding effective management. In this talk, I will explain how our group is using multiple traditional and emerging technologies to identify patterns of local and regional movement and habitat use and to quantify the flow and diversity of nutrients from different estuarine habitats that fuel shorebird diets. Our interdisciplinary work is dependent upon key partnerships with government and community agencies, a feature that will ensure that our findings will serve to prioritize protection and restoration of shorebird habitat now and into a future.

Evolutionary ecology of sexual reproduction: sexual selection, reproductive interference, and community structure
Daisuke Kyogoku (The Museum of Nature and Human Activities)
In sexually reproducing organisms, mating with individuals of the opposite sex is necessary to produce offspring. Mating process raises competition for mating opportunities among same-sex individuals (i.e. sexual selection) and the conflict of evolutionary interest between the sexes (sexual conflict), which drive the evolution of reproductive traits. Because reproductive traits can mediate interspecific interactions (e.g. reproductive interference), reproductive trait evolution can eventually influence the community structure. In this talk, I present three different studies that are related to the evolutionary ecology of sexual reproduction, and by doing so I discuss ways in which sexual reproduction is relevant to the origin and/or maintenance of biodiversity. First, I show a likely case of sexual conflict in a sexually reproducing dandelion, where the timing of flower closure is influenced by the identity of the pollen deposited on the stigma. Second, I present a case study of how reproductive trait evolution due to within-species sexual selection can mediate the strength of reproductive interference in a pair of seed beetle species. Third, I present a simulation model of secondary contact with genetically incompatible hybridization. This model suggests that habitat segregation can evolve without tradeoff in resource use ability and that habitat segregation is more likely to be found in nature than species recognition divergence, which has historically been more appreciated than habitat segregation in this context. I will also briefly present some of my ongoing projects and discuss future research plans.

Title:
Agrobacterium tumefaciens Attachment and T-DNA Integration – understanding the “root” to infection of host plants
Summary:
While several aspects of A. tumefaciens infection and transformation of plants are well understood, there are questions that remain concerning the attachment of the bacteria to host plants and the integration of T- DNA into the host cell genome. Work from our lab has focused on these questions and has applied novel approaches in an attempt to gain a more thorough understanding of these steps in the infection.
The standard approach to genetically modify plants relies on Agrobacterium tumefaciens to transfer foreign DNA (T-DNA) into plant cells where it can become a permanent part of the plant cell’s genome and express engineered traits. While A. tumefaciens transformation of plants has been used extensively, there are aspects of the process that are incompletely understood. To study the timing and factors influencing the location of T-DNA insertions, we used a modified adapter ligation- mediated PCR strategy, coupled with next generation sequencing, to identify T-DNA integration sites into the genome of Arabidopsis.
Previous reports examining T-DNA integration have relied on selective conditions, floral dip transformation, artificial virulence induction or use of cultured suspension plant cells. Our approach attempts to closely match natural infection conditions by using cut Arabidopsis root segments infected with uninduced A. tumefaciens and no selection for T- DNA integration events. A more thorough understanding of T-DNA integration will guide future experiments to develop the techniques to engineer plants more efficiently than is currently possible.

Title:
The Urban Microbiome ? a new census of the city
Abstract:
Our recent work using culture-independent (metagenomic) based strategies to study microbial communities shows an unexpectedly high level of biodiversity in urban microbiomes in a number of sites including parks, waterways, subway systems, and green infrastructure installations. The factors underlying the establishment of these diverse communities are not well understood, but it suggests that urban microbial communities represent a significant unknown element of phylogenetic, genetic, and functional biodiversity. A better understanding of these influences on multiple aspects of biodiversity will inform the design, construction, placement, and maintenance of urban environmental elements (such as green infrastructure) to maximize their ecosystem services. More fundamentally, our work offers a novel platform for exploration of basic science aspects of dimensions of biodiversity.

Title: Quality Requirements for Acquiring Optical Data to Support Calibration, Validation, and Research (CVR) Exercises
Speaker: Dr. Stanford. B. Hooker (NASA/ Goddard Space Flight Center)
Chair: Koji Suzuki
Abstract: Above- and in-water observations of the apparent optical properties (AOPs) of water masses are collected to support vicarious calibration, algorithm validation, and basic research — hereafter, calibration, validation, and research (CVR) — exercises for remote sensing missions. Although it is perhaps appealing to imagine these activities can be considered distinct and separate, especially from a legacy perspective (e.g., SeaWiFS and OCTS), there are two significant reasons why CVR activities require the same quality metrics during data acquisition for next-generation missions (e.g., PACE and SGLI): a) the underlying NASA Ocean Optics Protocols are essentially the same and are expected to be strictly adhered to; and b) the data is submitted to databases (e.g., SeaBASS) that do not make a distinction as to the original objectives for acquiring the data. Consequently, all optical data are ultimately applied to all three activities and noncompliance to the quality requirements degrades the capabilities of all future users of the data within the global community of practice. This presentation provides the quantitative lessons established by the author who has personally made more than 13,000 above- and in-water discrete optical measurements in the world ocean, and who has designed and co-developed state-of-the-art instruments, as well as data acquisition and processing software.
