Kyrstn Zylich – Senior Research Assistant

KrystenPhotoCroppedKyrstn completed her BSc in Biology at the University of British Columbia. Although unsure of where her degree would take her, the ocean had always held a special place in her heart. Growing up only an hour away from Vancouver allowed for numerous trips to the aquarium which helped instill a curiosity of marine organisms. As well, she has enjoying several family vacations to Hawaii which included snorkeling with turtles and other incredible sea life. After joining the Sea Around Us as a volunteer in February of 2011 she completed her first reconstruction on the island of Tokelau. Once joining the project fulltime as a staff member later that year, she has continued working on catch reconstructions, focusing mainly on South Pacific island countries. Kyrstn is now the senior research assistant of Sea Around Us and works on all aspects of the project including data updates, data quality checks, and report editing/formatting.

Dalal Al-Abdulrazzak – Ph.D. Student

DalalBioPic2Hailing from Kuwait City, Kuwait , Dalal Al-Abdulrazzak entertained an early passion for marine biology by spending countless hours submerged amongst the coral reefs of the Persian Gulf. Her enthusiasm for marine life grew into a lifelong love for ecology and conservation. After graduating cum laude with a BA in Environmental Studies & Conservation Biology from Middlebury College, VT, Dalal received a Watson Fellowship to travel to Panama, the Bahamas, New Zealand, Fiji, Palau, the Seychelles, and South Africa to research the extent to which cultural context influences shark conservation efforts. From 2013-2015 she worked as a Marine Policy Analyst with the Water and Oceans Governance Group at the UNDP Headquarters in New York City.

In 2015 she completed her PhD dissertation  entitled “In the Wake of the Dhow: Historical Changes in the Marine Ecology and Fisheries of the Persian Gulf” under the supervision of Dr. Daniel Pauly, and is currently a Post-Doctoral Research Fellow with the Sea Around Us. Her current research interests lie in the historical marine ecology of the Persian Gulf. Through a variety of historical documents she hopes to assess and quantify changes in the distribution and abundance of marine species in the Gulf in order to establish more accurate baselines from which to measure changes.

William Cheung – Associated Faculty

williamDr. William Cheung is a Professor at the Institute for the Oceans and Fisheries, UBC and the Director (Science) of the Nippon Foundation-UBC Nereus Program. His main research areas include understanding the responses and vulnerabilities of marine ecosystems and fisheries to global change, and examining trade-offs in managing and conserving living marine resources. His works cut across multiple disciplines, from oceanography to ecology, economics and social sciences, and range from local to global scales.

William has published over 150 peer-reviewed publications [Google Scholar], including papers in leading international journals. William is also actively involved in international and regional initiatives that bridge science and policy. For instance, he was a Lead Author in the Working Group II of the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), a Coordinating Lead Author of the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) and Global Biodiversity Outlook. He serves as member of the editorial board of Fish and Fisheries, Fisheries Oceanography and Frontiers in Marine Sciences, and as scientific advisors in a number of international and local organizations including BioDiscovery, IUCN and WWF Canada.

William obtained his BSc in Biology and M.Phil. from the University of Hong Kong. He worked for WWF Hong Kong for two years, after which he completed his Ph.D. in Resource Management and Environmental Studies at UBC. From 2009 to 2011, he was Lecturer in Marine Ecosystem Services in the School of Environmental Sciences, University of East Anglia.

Ar’ash Tavakolie – Senior Web Developer

arash_bioAr’ash is a senior software developer, and comes from an engineering/Artificial Intelligence background. He has been designing and developing .NET based solutions for about eight years.

Ar’ash designs and maintains the Sea Around Us suite of web applications and the related databases. He is currently busy working on ‘SwordFish (SF)’, which will replace the core components of legacy code with a multi-tiered architecture [DataWarehouse + AnalysisEngine + ClientModules]. He is developing SF to make the web/databases applications more agile, extensible and also lower the maintenance costs. SwordFish is based on OLAP/BI, C#, and .NET technologies. SF prototypes showed that MDX querying language is closer to the domain and can reduce the lines of codes by 80%.

Ar’ash is also an avid tea fan and likes reading books. Currently his favorite novelist is Haruki Murakami and his favorite programming gargoyle/guru/writer is Martin Fowler “Any fool can write code that a computer can understand. Good programmers write code that humans can understand.” Ar’ash regularly and enthusiastically baffles project staff during meetings by trumping the biologists’ ability to talk in technical jargon.

Research Interests

Jellyfish populations are increasing in numerous ecosystems around the globe. Not surprisingly, these increases are not uniform across time and space. So why are jellyfish increasing in some places and not others? What are the consequences for humans and ecosystems? And what, if anything, can we do to manage or prevent increasing jellyfish blooms?

Jellyfish population dynamics are complex, partly because of the unique life cycles of many species. Jellyfish may exist as pulsing medusae, sessile polyps, or cysts capable of resisting harsh environmental conditions. Reproductive strategies include sexual and asexual reproduction, as well as hermaphroditism. As such, jellyfish populations are influenced by a variety of anthropogenic and environmental factors at different, often cryptic, life stages.

Increasing jellyfish populations can impact humans in both negative and positive ways. Industries such as tourism, aquaculture, fishing, power generation, desalination, and shipping have all reported considerable economic losses due to jellyfish blooms. In contrast, fisheries that harvest jellyfish for food are expanding around the globe, and jellyfish are now a popular draw for public aquaria. As both human and jellyfish populations increase, new interactions are sure to emerge, as jellyfish get in our way and as we find new ways to exploit them.

Ironically, it appears that in some cases, humans may be responsible for the observed increases in jellyfish populations. While there is no single cause of increasing jellyfish populations, there is evidence that fishing, pollution, aquaculture, shipping, global warming, and coastal development can all create conditions that favour jellyfish over fish. Most of these links are only correlative, but the rise of jellyfish in coastal ecosystems worldwide should be cause for concern. We may need to decide now whether or not we want our children to be eating jellyfish burgers. If our behaviour doesn’t change, they might not have a choice.
