Methodological constraints for the stable isotope analysis of different tissues: A comparison between muscle and whole‐body samples in freshwater gammarids

Limnology and Oceanography: Methods, EarlyView.
Abstract Carbon (δ13C) and nitrogen (δ15N) stable isotope ratios allow the reconstruction of food webs, provided that all trophic levels are properly characterized. In freshwater ecosystems, small‐bodied invertebrates often occupy central positions in food webs, with whole‐body samples commonly used for their stable isotope analysis, due to ...

The influence of marine benthic habitat data on systematic conservation planning: Rottnest island as a case study

, 2011
The need for mechanisms to protect, maintain and restore global marine biodiversity has been globally recognised. Systematic conservation planning algorithms, such as MARXAN, are now a preferred solution for designing marine protected areas (MPAs) that ...

Continental accumulation of fads2 copy numbers allows sticklebacks to thrive across a diversity of nutritional landscapes

Oikos, EarlyView.
Nutrients, including vital organic compounds, vary in availability across ecosystems, with the potential to act as a source of selection for traits that increase nutrient acquisition and biosynthesis. Compared to freshwaters, marine ecosystems are richer in the omega‐3 long‐chain polyunsaturated fatty acid (n‐3 LC‐PUFA) docosahexaenoic acid (DHA ...

Harmonizing Multi-Source Sonar Backscatter Datasets for Seabed Mapping Using Bulk Shift Approaches

Remote Sensing, 2020
The development of multibeam echosounders (MBES) as a seabed mapping tool has resulted in the widespread uptake of backscatter intensity as an indicator of seabed substrate properties.

Development of techniques to classify marine benthic habitats using hyperspectral imagery in oligotrophic, temperate waters

, 2009
There is an increasing need for more detailed knowledge about the spatial distribution and structure of shallow water benthic habitats for marine conservation and planning.

Potential Impacts of Low Flows on Fish Foodscapes and Production in a Braided River

River Research and Applications, EarlyView.
ABSTRACT Changes in river discharge affect the physical composition and connectivity of habitats which, in turn, may shape the spatial distribution of fish food abundance, accessibility and quality—the ‘foodscape’—of river ecosystems. However, the influence of river flows on fish foodscapes has received very little attention from scientists. We studied

West Florida Shelf pipeline serves as sea turtle benthic habitat based on in situ towed camera observations

Aquatic Biology, 2019
The use of marine offshore benthic habitats by sea turtles is poorly characterized due to the difficulty of obtaining in situ data. Understanding benthic habitat use that is important to the species’ reproduction, foraging, and migrations is critical for

Inter-relationships between benthic macroinvertebrates and habitat types in Broke Inlet, south-western Australia. Report to the Ernest Hodgkin Trust for Estuary Education and Research, September 2008

, 2008
The benthic macroinvertebrate fauna of Broke Inlet, a seasonally-open estuary located in the South coast of Western Australia was sampled seasonally between spring 2007 and autumn 2008 at 20 nearshore sites throughout the estuary. These sites were chosen

Lessons Learnt From Long‐Term Monitoring of River Restoration in an English Chalk Stream

River Research and Applications, EarlyView.
ABSTRACT River restoration can be difficult to evaluate due to insufficient monitoring over timescales too short to adequately capture physical and ecological response. To better understand restoration outcomes, this study quantified changes in physical habitat (depth, velocity, substrate composition) and macroinvertebrates at two restoration projects ...
