<\/a><\/p>\nOn an early morning of February 2015, I am waiting at the airport for my flight to PORTLAND\/PDX. I\u2019ve had only one day to pack but I feel confident that I\u2019ve made the right choices as my 23kg luggage contains mainly jumpers, sweatshirts, thick socks, and a brand new umbrella. I\u2019ve got everything I need to face my four months internship in rainy Newport, Oregon.<\/p>\n
A few disillusionments await me when I finally land: 1) my \u201csaucisson\u201d (fancy sausage) can\u2019t pass customs and ends up in a bin despite my attempts to negotiate with the customs official, and 2) as soon as I am out of the airport, it starts raining. At first sight this looks like the harmless kind of drizzle I\u2019ve experienced in England, until I realize it\u2019s raining sideways! So much for buying a new umbrella\u2026<\/p>\n
Luckily, these small inconveniences don\u2019t affect my spirits for long as I get to discover the richnesses Oregon has to offer.<\/p>\n
My mouth drops open the first time someone tells me that I can see elk around Newport and that gray whales are commonly observed next to the jetty at this time of year. It\u2019s difficult to describe to someone who\u2019s always been living in this environment how exciting it is to me. I am not used to all this wilderness and certainly not to living so close to it. It\u2019s a thrill to think that I only need to ride my bike for a few miles to meet the amazing local fauna.<\/p>\n Of course, the beauty of Oregon\u2019s landscapes and the richness of its wildlife is not the only thing that catches my attention. I am immediately touched by the kindness of people, the sense of sharing and the deeply rooted sense of community. I feel welcomed at HMSC, and by my colleagues in the GEMM lab and I am eager to start my internship.<\/p>\n So what is my work here exactly?<\/p>\n Well, believe it or not, I\u2019ve crossed the Atlantic Ocean and came to the US to actually work on a species of dolphins endemic to New-Zealand! Dr Leigh Torres, and I are investigating the fine-scale distribution and habitat selection patterns of Maui\u2019s dolphin (Cephalorhyncus hectori maui<\/em>). This subspecies of the more common Hector\u2019s dolphin (Cephalorhyncus hectori, <\/em>also endemic to New-Zealand) is the smallest dolphin in the world and unfortunately among the most endangered (listed as \u201ccritically endangered\u201d by the IUCN). The Maui\u2019s dolphin population is thought to have decreased to under 100 individuals in the past decades.<\/p>\n In practice, this means I am doing data analysis so I spend my days in front of my computer. This may sound a bit dull, but computer work is actually a great part of research in ecology (apart from awesome field work stage, but this is only the tip of the iceberg). Speaking for myself, I\u2019ve always found it very exciting to put together all this hard-won data to answer important questions, especially when the conservation of species as emblematic as the Maui\u2019s dolphin is at stake. To tell the truth, the nerdy code writing work is also a lot of fun!<\/p>\n My data set consists of boat-based observations of Maui dolphin groups made during the 2010, 2011, 2013 and 2015 summer surveys. Overall about a hundred groups were observed. Based on these observations we would like to know: WHERE are the Maui dolphins (distribution pattern)? And WHY (habitat preferences)?<\/p>\n My job is first to describe the spatial distribution patterns of these observations given the year, composition of groups, or group behaviour (whether animals were feeding, resting etc.). This can be done using kernel density estimates: a very good method for \u201csmoothing\u201d a distribution in 2 dimensions and highlighting its main characteristics (extent, core areas etc.). This allows us to answer (or try to answer) the \u201cWHERE\u201d question.<\/p>\n The second stage of my analysis is to describe the environmental conditions at each of the dolphin group locations and compare them with the environmental conditions in surveyed areas where Maui dolphins where not observed. This allows us to better understand the environmental cues that Maui dolphins might be following to find \u201csuitable\u201d places for their every-day activities and therefore try answer the \u201cWHY\u201d question. In statistical jargon, we are exploring the relationship between probability of presence of Maui dolphins and environmental predictors such as: sea surface temperature, turbidity of the water, distance to closest river mouths, distance to the coast and depth.<\/p>\n The resulting models will be used to predict seasonal variations in Maui\u2019s dolphin distribution, notably in winter when direct surveying is difficult because of weather conditions. Based on the resulting dynamic distribution models, we finally aim to predict how Maui\u2019s dolphins might interact with anthropogenic activities or react to changes in their environment.<\/p>\n So far, preliminary results are very promising and I am hoping to share these soon!<\/p>\n","protected":false},"excerpt":{"rendered":" My name is Sol\u00e8ne Derville and I am a master\u2019s student in the Department of Biology at the Ecole Normale Sup\u00e9rieure of Lyon, France.
