Abstract The movements of aquatic animals affect their exposure to threats and the efficacy conservation measures, such as Marine Protected Areas (MPAs). However, many species’ remain poorly understood difficult reconstruct from available datasets, hampering efforts. This is especially case for species that rarely surface, which data are often limited observations acoustic telemetry (detections) ancillary sensors, archival tags. Here, we pioneer use state-of-the-art particle algorithms model...
By linking iterative learning and knowledge generation with power-sharing, adaptive co-management (ACM) provides a potential solution to resolving complex social-ecological problems. In this paper we evaluate ACM as mechanism for conservation conflict using case study in Scotland, where seal salmon fishery stakeholders have opposing entrenched objectives. emerged 2002, successfully long-standing conflict. Applying evaluation approaches from the literature, 2011 interviewed characterise...
Water stress (LWP) was measured in honey mesquite, Prosopis glandulosa var. [Torr.], trees by using pressure—chamber method to detect negative hydrostatic pressure the xylem of leaf petioles. The sufficiently sensitive measure short—term changes ± 1 bar LWP throughout diurnal priod. Mean differenes between sun—exposed and shaded leaves averaged 4.7 bars on a clear day May. Although mean for five ranged from 15.8 18.1 LWP, interaction exposure tree relatively minor comparison with large...
Abstract While elasmobranchs are often a designated feature in Marine Protected Areas, there few studies that have evaluated the effectiveness of spatial fishery restrictions on their recovery. Here we examine critically endangered flapper skate, Dipturus intermedius , based changes abundance, demography and survival rate. Trends local abundance at two sites within Loch Sunart to Sound Jura Area (LStSJ MPA), were contrasted with surrounding waters off west Scotland where fishing remains...
Abstract Flapper skates ( Dipturus intermedius ) were once widespread in European shelf waters but are currently classified as critically endangered by the International Union for Conservation of Nature due to historical overexploitation. Novel monitoring approaches needed assess efficacy management measures, such dedicated marine protected areas, conservation relict skate populations. possess distinctive dorsal spot patterns, which could potentially be used individual recognition using...
Abstract This study provides the first report of an egg nursery for Critically Endangered flapper skate Dipturus intermedius and a description habitat, thus contributing towards our understanding essential habitats species. In total, 1,395 cases were recorded (accounting overlapping surveys) in two case collection dives ( n = 67 cases), one photogrammetry dive 10 509 drop‐down video (DDV) camera drifts 510 cases) 18 remote operated vehicle (ROV) flights 1,031 carried out Inner Sound on west...
Abstract Catch-and-release angling is a popular recreational pastime and an essential component of many fish research programmes. Marked physiological disturbances have been documented in elasmobranchs response to handling, but skates rays remain understudied. Here, we describe for the first time responses critically endangered flapper skate (Dipturus intermedius) angling, handling tagging Scotland. Sixty-one were captured by as part programme. We assessed individual health, measured blood...
Abstract Diurnal and seasonal water relations were measured in selected species of a Banksia woodland at site with groundwater depth 6–7 m. The canopy co‐dominants attenuata menziesii exhibited similar patterns variation relations, both diurnally seasonally. Stomatal conductance was usually 0.4–0.5 cm s −1 seasonally and, generally, did not respond to deficit other factors. Transpiration correlated positively factors indicative atmospheric evaporative demand, especially total global...
Seasonal and ontogenetic variations in depth use by benthic species are often concomitant with changes their spatial distribution. This has implications for the efficacy of conservation measures such as marine protected areas (MPAs). The critically endangered flapper skate ( Dipturus intermedius ) is designation feature an MPA Scotland. generally associated deeper waters >100 m; however, little known about its seasonal or variation habitat use. study used archival data from 25...
Abstract Marine Protected Areas (MPAs) are widely used in marine management, but for mobile species understanding the spatio‐temporal scale of management measures that is required to deliver conservation benefits depends on a detailed knowledge species’ movements often lacking. This especially case skate (Rajidae) which relatively few movement studies have been conducted. In Scotland, Loch Sunart Sound Jura MPA covering 741 km 2 has designated Critically Endangered flapper ( Dipturus...
An egg of the critically endangered flapper skate Dipturus intermedius was successfully incubated to hatching in captivity what is believed be a first for species. Water conditions (temperature, salinity, flow rate) were recorded, with mean water temperatures ranging from monthly 8.3 ± 1.2 13.2 0.3°C and salinity 30.5 36.6 2.3 ppt. Hatching occurred after 534 days, suggesting that eggs take c. 5700 growing degree-days incubate hatching. The egg's prolonged embryonic development raises...
Abstract Trends in depth and vertical activity reflect the behaviour, habitat use preferences of marine organisms. However, among elasmobranchs, research has focused heavily on pelagic sharks, while movements benthic such as skate (Rajidae), remain understudied. In this study, Critically Endangered flapper ( Dipturus intermedius ) were investigated using archival data collected at 2 min intervals from 21 individuals off west coast Scotland (56.5°N, −5.5°W) 2016–17. Depth records comprised...
Catch-and-release angling is widespread, but the impacts of this practice for captured individuals are understudied, especially among elasmobranchs. Studies on sub-lethal behavioural particularly sparse, despite their importance interpretation biologging data and assessments species’ tolerance to capture. In study, responses flapper skate ( Dipturus intermedius ) catch-and-release were described first time, using archival observations (depth temperature) 21 tag deployment/retrieval events...
Stability and long-term persistence of a species rely heavily on its genetic diversity, which is closely allied to capacity for adaptation. In threatened species, population connectivity can play major role in maintaining that assessments their populations be crucial the design effective spatial conservation management. Not only it worth evaluating amount diversity candidate protection, but magnitude outgoing gene flow provide insight into potential replenish others via emigrants. The...
Abstract Diurnal and seasonal water relations were measured in understorey species from a Banksia woodland. The shrubs exhibited various responses to summer drought. Stirlingia latifolia had high xylem pressure potential transpiration late summer. Adenanthos cygnorum maintained year round with dawn values around − 0.3 MPa minimum −1.3 MPa, but showed severe restriction of Eremaea pauciflora Jacksonia floribunda levels early summer, stress when rates low potentials as 5.5 MPa.

Abstract Aggregations of the tube worm Serpula vermicularis were discovered in July 2006 upper basin Loch Teacuis, Morvern, Western Scotland. aggregations have been previously described only from five other locations Europe. Occurrence habitat Teacuis was mapped by scuba diving. Small mean (±SD) height 26±9 cm (n=59) and diameter 19±10 found growing on rocks amongst kelp holdfasts around margins loch at a depth 1–5 m. A brief sublittoral survey carried out 1996 did not find any S. despite...
Abstract In the UK, reef formation by tubicolous polychaete Serpula vermicularis L. has been recorded in only two sea lochs Argyll, west Scotland. aggregations are now confined to Loch Creran, those Sween having died out for unknown reasons. Survivorship and tube extension rates were measured situ order compare habitat quality of determine feasibility artificial restoration reefs using stock translocated from Creran. After labelling measurement, clusters inhabited tubes collected Creran...
Abstract Knowledge of vital data such as growth and age at maturity is necessary to develop effective management strategies for endangered species. The Critically Endangered flapper skate ( Dipturus intermedius ) the largest in North Atlantic information, assess key life‐history traits, populations’ rates anticipate their response measures, still lacking. While classical estimation methods used fish generally require analysis calcified structures, destructive are incompatible with...
Abstract Developments in animal electronic tagging and tracking have transformed the field of movement ecology, but interest is also growing contributions tagged animals to oceanography. Animal-borne sensors can address data gaps, improve ocean model skill support validation, previous studies this area focused almost exclusively on satellite-telemetered seabirds seals. Here, for first time, we develop use benthic species as oceanographers by combining archival (depth temperature) from...
Abstract Many marine species exhibit complex and diverse movements that vary across spatial temporal scales. These must be accounted for when designing effective management conservation efforts. While environmental cues such as temperature salinity have been shown to influence the of mobile species, it is increasingly documented social factors can also space use population behaviour. Understanding how various movement enhances our ability predict highly dynamic ocean species. Spurdog (...
