New paper with @beatezein.bsky.social & @jedalong.bsky.social:

⭐A new data-driven paradigm for the study of avian migratory navigation⭐

We propose how the multi-modal multi-scale nature of navigation could be studied w/ data mining, machine learning & AI.

A new data-driven paradigm for the study of avian migratory navigation - Movement Ecology
Avian navigation has fascinated researchers for many years. Yet, despite a vast amount of literature on the topic it remains a mystery how birds are able to find their way across long distances while ...

A 3,500 year-old Egyptian glass cosmetic jar with two little duck heads!

Glass was a relatively new material at that time, so this jar would have been a precious possession.

From Merit’s beauty case, found inside Theban tomb (TT8) of Merit and her husband Kha in 1906. 📷 Museo Egizio

#Archaeology
Museo Egizio Turin photo showing a small, dark-blue, core-formed, round glass jar which tapers in at the shoulders below the neck. It has yellow, white, and light blue festoon decoration trailed around the main body. There is a single yellow trail just below the neck of the jar. There is a dark-blue circular glass lid, the top of which is adorned with two dark-blue duck heads with yellow bills, a yellow trailed stripe on the top of each duck’s head, and indents for their eyes. The jar is displayed on a perspex (?) stand against a grey background. Glass jar dimensions: 7.6 cm x 9.6 cm. Core-forming is one of the earliest glassmaking techniques. Glassmakers shaped the body of the vessel around a core, wound colored trails around it. They then let the vessel cool and removed the core.

Six weeks ago, I picked up a year-old tawny owl with a broken leg off the main road near our home and dropped him off at our nearest vet.

After a few days, I received one of the most bizarre phone calls I’ve ever had, asking “So when are you coming to pick up your owl?” 🧵

Some things never change!

4,000 year-old ancient Egyptian writing board with a student’s many spelling mistakes corrected in red ink by the teacher! 😂

📷 The Met www.metmuseum.org/art/collecti...

#Archaeology
Met museum photo of an ancient Egyptian rectangular wooden white-washed writing board with an exercise written in black hieratic script. It was written by a student named Iny-su whose spelling mistakes are corrected in red ink by the teacher. Hieratic script is an ancient Egyptian cursive version of hieroglyphics. The board measures 19 cm long x 43 cm wide and has a horizontal crack half way down the left-hand side. The wooden board was painted with white gesso, which now appears cream-coloured. This allowed boards to be whitewashed for use over and again. The exercise is a practice in formal letter writing. The student Iny-su addresses the letter (presumably jokingly) to his brother Peh-ny-su, treating him like a wealthy authority figure. Wood, gesso, paint pigment. Middle Kingdom, Dynasty 12, c. 1981–1802 BC.

The condition of fabrics from pile dwelling and wetland settlements is amazing. This charred ball of thread was found at the site of Marin-Epagnier/Préfargier. It was made of hemp or lime fibres, and dates about 3900 to 3300 BC. The thread measures a total of about 10 m in length.

Join Mia Wege and me to study niche partitioning among three Antarctic mesopredators!

Fully-funded PhD opportunity at U Canterbury, please email [email protected] if you're interested!

Applications will be reviewed until filled.
Fluffy Weddell seal pup looks straight into the camera We are seeking a motivated PhD student to investigate how multiple mesopredators share space and resources in the Southern Ross Sea. The project will address questions about niche partitioning (both spatial and temporal) and foraging ecology in the Southern Ocean using three years of animal tracking data deployed on penguins (n = 60) and seals (n = 30). Specifically, we wish to uncover aspects of three-dimensional space use in Adélie penguins, emperor penguins, and Weddell seals at Cape Crozier, in the southern Ross Sea. There exists one of the largest colonies of Adélie penguins, a small colony of emperor penguins, and a small group of Weddell seals. We ask: How are these animals using the same space at the same time? How can that part of the ocean support hundreds of thousands of central-place foragers in a relatively small foraging halo, during the short summer window of time? Answers to these questions will provide fine-scale insights as part of the larger project which seeks to understand the metacommunity structure of marine mesopredators in the Southern Ocean and will inform conservation in the Ross Sea Marine Protected Area (one of the largest in the world). With the first 10-year evaluation of the MPA coming up, this project will have immediate real-world impact. We cannot guarantee Antarctic field work as part of the PhD project. Funding: Rutherford Discovery Fellowship ($27,000 NZD/year for three years + fees), plus potential school-supported (School of Earth and Environment) conference travel opportunities. Requirements: Bachelor’s and Master’s degree in Ecology, Marine Biology, Geography, Zoology or Statistics required; good communication skills (written and verbal), with previous publication experience a bonus; strong work ethic, strong initiative, and team attitude; previous experience handling biologging data (in any system), large datasets, and data wrangling a plus.
