Seagrass meadows support key ecosystem services, via provision of food directly for herbivores, and indirectly to their predators. The importance herbivores in seagrass has been well-documented, but the links between webs services have not previously made explicit. Herbivores interact with - including carbon sequestration, cultural values, coastal protection. Interactions can be positive or negative depend on a range factors herbivore identity grazing type intensity. There unintended...
Abstract Structural habitat complexity is a fundamental attribute influencing ecological food webs. Simplification of complex habitats occurs due to both natural and anthropogenic pressures that can alter productivity Relationships between web structure may be influenced by multiple mechanisms, untangling these challenging. We investigated whether (1) size spectra vary across gradient in seagrass meadows (2) structural changes the importance different primary producers supporting (determined...
Summary Coral reefs directly support the well‐being of millions people across Southeast Asia, however, these critical ecosystems are also under immense pressure, threatening their sustainability. reef restoration has emerged as a promising strategy to contribute safeguarding and securing socioeconomic benefits they provide local communities region. In this paper, we present outcomes week‐long deliberations between policymakers, research funders, practitioners scientists from Indonesia,...
Abstract Aim Understanding patterns in the abundance of species across thermal ranges can give useful insights into potential impacts climate change. The abundant‐centre hypothesis suggests that will reach peak at centre their range where conditions are optimal, but evidence support this is mixed and limited geographical taxonomic scope. We tested applicability a intertidal organisms using large, citizen science‐generated data set. Location UK. Methods Species' records were matched with...
Citizen science represents an effective means of collecting ecological data; however, the quality/reliability these data is often questioned. Quality assurance procedures are therefore important to determine validity citizen and promote confidence in conclusions. Here, generated by a marine project conducted at 12 sites across United Kingdom was used investigate whether use simple, low-taxonomic-resolution field-monitoring protocol allowed trained scientists generate comparable those...
Crawford, R.J.M., Nel, D.C, Williams, A.J. & Scott, A. 1997. Seasonal patterns of abundance Kelp Gulls Larus dominicanus at breeding and non-breeding localities in southern Africa. Ostrich 68 (1): 37–41. At Malgas Island, Western Cape Province, South Africa, active nest sites were recorded from August to February, but mainly between October December with a peak November. In September all recently-made scrapes without eggs or chicks. Eggs found early until January chicks late February. Dassen...
Macroherbivory is an important process in seagrass meadows worldwide; however, the impact of macroherbivores on seagrasses Great Barrier Reef (GBR) has received little attention. We used exclusion cages and tethering assays to understand how intensity macroherbivory varies over space time around Green Island (Queensland), what this overall meadow structure. Rates were comparatively low, between 0.25–44% daily productivity; rates highly variable a one-year period, among sites. Loss material...
A study of an inshore southern North Sea population lesser weever, Echiichthys vipera , on the Suffolk coast, England, found this small, abundant, benthic fish to reach age 15 years and suffer adult mortality rate only 0.23 y −1 . The maximum length observed 195 mm Standard (SL) (225 total length, TL) was greatest yet reported many individuals >140 SL (163 were caught between 2009 2012. Previous studies have a 160 TL von Bertalanffy asymptotic 150.3 mm. Age structure analysis showed that...

Megaherbivore grazing (e.g. by turtles, and sirenians) plays a major well-documented role in structuring seagrass meadows around the world; however, we know little about local-scale (intra- inter-meadow) variability megaherbivore grazing. This is surprising given that megaherbivores are highly selective eaters who may feed targeting certain meadows, or areas within meadow. We ran an experiment Great Barrier Reef to test question: How does megaherbivory vary on regional scale? used exclusion...
Recent studies have shown that seagrasses could possess potential applications in the treatment of inflammatory disorders. Five seagrass species (Zostera muelleri, Halodule uninervis, Cymodocea rotundata, Syringodium isoetifolium, and Thalassia hemprichii) from Great Barrier Reef (QLD, Australia) were thus collected, their preliminary antioxidant anti-inflammatory activities evaluated. From acetone extracts five subjected to 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay,...
Assisted coral recovery (ACR) initiatives are establishing rapidly in reefs worldwide, using a variety of devices and techniques. In the Great Barrier Reef (GBR, Reef), site-scale ACR field trials occurring at multiple sites Cairns-Port Douglas region through stewardship activities involving GBR tourism operators, Traditional Owners, not-for-profit organisations. It is hypothesised that these presence reef do not negatively affect visitor experiences, when accompanied by appropriate...
