Survey rationale Coastal Creatures was a two year project (July 2016 - Septmber 2018) which focused on the diverse marine and coastal natural heritage of the North Devon Coast Areas of Outstanding Natural Beauty (AONB). During the project we provided citizen science opportunities to identify, record, enjoy and learn about the varied flora and fauna of our diverse intertidal and coastal habitats. To better understand our coast, we focused on four beaches along the AONB coast with a range of habitats and species. The focus beaches were Northam Burrows (Westward Ho! and Greysands), Croyde, Lee Bay and Combe Martin. The species census surveys which are the focus of this report formed the marjority of our citizen science surveying effort. 2. Methodology 2.1. Survey locations During February 2017 and July 2018 as part of the Coastal Creatures project a series of 23 species census surveys were undertaken on four rocky shores (in the intertidal zone) along the North Devon Coast AONB ( Figure 1): • Combe Martin (five sucessful surveys, one cancelled survey) • Lee Bay (six successful surveys) • Croyde (six sucessful surveys) • Westward Ho! (six sucessful surveys, one cancelled survey). Figure 1: Map of the North Devon Coast AONB with target beaches highlighted. 2.2 Volunteer training and survey protocol Volunteers were recruited and then during a workshop in February 2017, they were trained on how to complete the survey methodology by the NDC AONB Education and Interpretation Officer. The marjority of the survey group were recruited from Coastwise North Devon (http://www.coastwisenorthdevon.org.uk/). Other volunteers were recruited via online advertisement, leaflets and posters distributed at festivals and shows. Below are the instructions given to volunteers to complete the survey. Coastal Creatures Species Census As part of the Coastal Creatures project we will be undertaking a species census across four beaches along the North Devon Coast AONB. To take part in this species census please refer to the following survey methodology: 1. The survey will take place over a one-hour period (preferably half an hour either side of low tide). 2. In pairs decide who will be the surveyor and who will be the photographer (it is okay to switch roles within the survey time). 3. Decide which phylum (species group) you would like to focus on. Alternatively you can choose to do a generalist survey and record everything you find. Please use the corresponding sheet which you would like to use. Use the forms as a guide, there is plenty of space on the back of each sheet for additional species. The phyla being focused on in this survey include: • arthropods (including crustaceans), • molluscs, • cnidarians, annelids, bryozoans, porifera, • chordates (including vertebrates and ascidians), echinoderms • and also algae. 4. Fill in both your names on the form, date and the camera number you are using. 5. It is vital that you take a photo of each species and record photo number(s). 6. Record height of species record on shore (H = high, M = middle, L = low) and record the abundance if possible using the SACFOR scale (Appendix 1). 6. Once completed return forms and cameras to Cat (NDC AONB Education Officer). Thank you for taking part

  • The Distribution and Behavior of Actinia Schmidti
    The distribution and behavior of Actinia schmidti By: Casandra Cortez, Monica Falcon, Paola Loria, & Arielle Spring Fall 2016 Abstract: The distribution and behavior of Actinia schmidti was investigated in Calvi, Corsica at the STARESO field station through field observations and lab experiments. Distribution was analyzed by recording distance from the nearest neighboring anemone and was found to be in a clumped distribution. The aggression of anemones was tested by collecting anemones found in clumps and farther away. Anemones were paired and their behavior was recorded. We found that clumped anemones do not fight with each other, while anemones found farther than 0.1 meters displayed aggressive behaviors. We assume that clumped anemones do not fight due to kinship. We hypothesized that another reason for clumped distribution could be the availability of resources. To test this, plankton samples were gathered in areas of clumped and unclumped anemones. We found that there is a higher plankton abundance in areas with clumped anemones. Due to these results, we believe that the clumping of anemones is associated to kinship and availability of resources. Introduction: Organisms in nature can be distributed in three different ways; random, uniform, or clumped. A random distribution is rare and only occurs when the environment is uniform, resources are equally available, and interactions among members of a population do not include patterns of attraction or avoidance (Smith and Smith 2001). Uniform, or regular distribution, happens when individuals are more evenly spaced than would occur by chance. This may be driven by intraspecific competition by members of a population. Clumped distribution is the most common in nature, it can result from an organism’s response to habitat differences.

Although any physical or numerical model 10 that aims to replicate flow-vegetation interactions requires these characteristics, information 11 on morphology and mechanics of vegetation living in coastal waters remains insufficient. The 12 present study investigates the mechanical properties of blades of Saccharina latissima, a 13 seaweed species spread along the shores of the UK and North East Atlantic. More than 50 14 seaweed samples with lengths spanning from 150 mm to 650 mm were collected from Loch 15 Fyne (Scotland) and tested. Seaweed blades had a natural ‘stretched droplet’ shape with 16 bullations in the central fascia and ruffled edges in the area close to the stipe. Their 17 morphological features showed high variability for samples longer than 400 mm. The blades 18 were almost neutrally buoyant, their material was found to be very flexible and ductile, being 19 stiffer in longer blades. The laboratory tests showed that estimates of tensile Young’s 20 modulus appeared to be similar to bending Young’s modulus suggesting a reasonable degree 21 of isotropy in studied seaweed tissues. 22 Keywords: 1 23 Brown alga; organism morphology; mechanical properties; elasticity; Saccharina latissima; 24 Scotland 25 1.

  • Protection Over Mobility? How Shell Selection in the Hermit Crab Clibanarius Erythropus (Paguroidea) Is Modulated by Availability and Ecological Conditions
    Protection over mobility? How shell selection in the hermit crab Clibanarius erythropus (Paguroidea) is modulated by availability and ecological conditions. Dressler, Lena Elisa; [email protected] Ebel, Roy; [email protected] Ehlers, Sarah; [email protected] Abstract Hermit crabs occupy empty gastropods shells, which have to provide both: mobility and protection. Yet, the process of shell selection and the preference for different architectural traits, such as globose or conical shapes, has not been fully understood. In this study we look into the selection behaviour of Clibanarius erythropus. Five gastropod shell types of similar size were offered in a laboratory setup. The results were compared to findings in a natural habitat in Le Cabellou, located on the French Atlantic Coast. Moreover, the radius of movement between consecutive tides was studied to infer how C. erythropus obtains shells in the absence of live gastropods. When offered in equal amounts, a vast majority selected a shell of conical shape as a final shelter, either Tritia reticulata or, to a lesser extent, Nucella lapillus. Consistent with this, these two gastropods provided the shells first selected and occupied the most time during the experiment. A similar preference for a conical shape was observed in the field. Yet, a greater fraction was found to occupy N. lapillus. Moreover, after two tides, 47 % of specimens were recovered in close vicinity to their original location. Due to this locational constancy we presume that the population depends on a passive import of certain shells. The different abundance of empty gastropod shells is likely to constitute a limiting factor that modulates shell selection under natural conditions.
