Canter-Lund 2019

This award was established by the British Phycological Society in recognition of Hilda Canter-Lund, whose stunning photographs will be known to many members. Her photomicrographs of freshwater algae combined high technical and aesthetic qualities whilst still capturing the quintessence of the organisms she was studying.

Winners 2019

Zoe Loffler: Symphony of seaweed

The amazing variety and wonderful colours of seaweeds are no surprise to seaweed lovers!  This is a photo to show those unfamiliar with seaweeds that they are not just brown and smelly…! This image was taken at low tide near Apollo Bay, Victoria, Australia, while on a family camping trip.

Zoe grew up diving in temperate waters near Melbourne, Australia. She completed her undergraduate degree and PhD at James Cook University in Townsville, Australia, studying the ecology of canopy-forming seaweeds (particularly Sargassum spp.) on coral reefs. She is now based in Sydney, and loves snorkelling and diving in temperate waters where there is such a wonderful diversity and abundance of seaweeds.  She took this picture on a Google Nexus 5x Smartphone. “It’s actually getting pretty outdated these days”, said Zoe, “it really goes to show that you don’t always need the best equipment to take a nice photo; sometimes the subject matter does all the work for you.”

A bloom of benthic blue diatoms of the genus Haslea (H. ostrearia, H. provincialis) covering macroalgae communities (Padina pavonica, Acetabularia acetabulum, Halopteris scoparia, Dictyotasp.) in the shallow water of Calvi Bay (Corsica, France). There, these diatoms regularly develop at a depth of 2 to 8 meters in Spring, particularly amongst these algae but also within the community of filamentous and mucilaginous epiphytes (Nematochrysopsis marina, Acinetospora crinita, Chrysonephos lewisii, Chrysoreinhardia giraudii)that appears seasonally in these habitats. For scale, the circular caps on the end of the Acetabulariastalks are 5 – 10 mm in diameter.   Blue diatoms of the Hasleagenus produce blue pigments called marennine and marennine-like pigments, which have allelopathic, antibacterial and other properties. Nonetheless, the bloom dynamics of these blue Hasleain coastal environments as well as their potential interactions with macroalgal-epiphytic communities are little understood. The image was taken at a depth of four metres in May 2018 with a LUMIX TZ10 in a DMW-MCTZ10 marine housing, under natural light conditions, whilst scuba-diving along rocky shores of the Revellatta peninsula (Calvi Bay).

Damien Sirjacobs has an MSc in Bio-Engineering and in Oceanology  and received his Ph.D.in 2011 from the Oceanology Laboratory of the University of Liege (Belgium) and the University of the Azores (Portugal), studying the ecology and population dynamics of the macroalga Codium elisabethae in Faial (Azores) with the support of seabed imagery.  Subsequently he has been involved in marine geostatistics, bioinformatics and algae biodiversity and ecology.  He is now a teaching and research assistant at the Eucaryotic Phylogenomics Unit of the University of Liege, pursuing research themes related to the diversity, distribution and dynamics of seaweeds and benthic microalgae.  This work is focussed on 40 years of records from the Mediterranean reference site of Calvi Bay through joint efforts by the STARESO research station and the University of Liege, and more recently, the STARE-CAPMED project, and associated projects such as H2020 GHaNA [http://ghana.univ-lemans.fr/en/index.html]

Forrest Lefler: Cyanobacterial Entanglement
Culture of cyanobacteria photographed under 400x magnification
John Huisman: The next generation:Martensia denticulata, with cystocarps
This image was taken in-situ at Cape Peron, Western Australia and shows a specimen of the net-like M. denticulata with numerous pale pink, globose cystocarps (the phase produced after fertilization). Equipment used was a Sony RXIII camera in a Nauticam housing with twin Inon strobes. A macro lens was added to enable the close focus. For scale, each of the cystocarps is approximately 1 mm in diameter
Leon Katona: Pedestal of Productivity
I captured this algaescape in an aquarium mesocosm at the end of a long-term photophysiology experiment. Color has been corrected to better reflect natural tones. The image shows a column of very productive cyanobacteria (Phormidium sp. and Oscillatoria sp.) and golden algae (mostly small diatoms) in a thick matrix of extracellular material. Attached algae were grown on ceramic tiles under a light gradient. This column was grown under high irradiance and inorganic nutrients, and responded quite positively to those conditions! Plentiful resources allowed these algae to supersaturate the water with air bubbles due to high rates of photosynthesis.
William Murray: Majestic Micrasterias

The beautiful symmetry of this Desmid showing off the intricacies of every characteristic of the individual cell; the isthmus, apical and lateral lobes all in perfect harmony, along with help from the striking color of the chloroplast from the phase contrast.
