Differences in diet have implications for potential ecosystem roles of two key rocky reef fishNARA Subscribed
The influence of fishes on temperate rocky reef ecosystems is globally recognised, particularly where large predators may structure ecosystems through predation. In South-East Australia, the common Wrasse Achoerodus viridis (Blue Groper) and Sparid Chrysophrys auratus (Snapper) are sympatric rocky reef predators. While their diets are thought to be well understood, this is generally based on gut contents undertaken over limite...
Ethics in archaeobotany: identifying current issues and initiating a declaration of principlesNARA Subscribed
This article presents the first systematic assessment of ethical concerns specific to archaeobotanical research, focusing on principles and values. Conducted by an international group of archaeobotanists, the study used an anonymous online survey to document experiences and perceptions within the archaeobotanical community with the aim of raising awareness, identifying prevalent good practices and noting points for improvement...
Urchin diets are a topic of global interest due to their impacts on subtidal reefs. Urchins can consume large amounts of macroalgae, leading to the loss of macroalgal forests and creation of “barrens”. However, there is scant dietary information in the southern hemisphere for the temperate sea urchin, Centrostephanus rodgersii , and what they consume within barrens, which lack macroalgae. Here, we sampled C. rodgersii to quant...
Corporations and financial institutions driving coastal conflicts involving Indigenous PeoplesNARA Subscribed
Socio-environmental conflicts associated with large-scale economic projects in Indigenous territories are well documented, but conflicts in coastal areas remain largely unexplored, despite the crucial differences between inland and coastal ecosystems. While the empirical literature about socio-environmental conflicts in Indigenous territories in coastal areas is growing, the role of financial institutions and corporations in t...
Trees with zygomorphic flowers can persist at lower abundances in diverse communitiesNARA Subscribed
Zygomorphy (bilateral symmetry) is a form of floral specialization that is thought to restrict pollination to fewer visitors, enhancing the effectiveness and precision of pollen transfer between conspecific flowers. In this way, zygomorphy may help the persistence (i.e., decrease extinction) of small and scattered populations, ensuring cross‐pollination even when individuals have few conspecifics nearby. In this study, we use...
Blood flukes cause serious health issues for farmed bluefin tuna worldwide. Their infection severity has been assessed by counting adult flukes in heart flushes. However, Cardicola orientalis adults reside in blood vessels in the gills. The aim of this study was to assess species composition, prevalence and intensity of adult blood fluke infection in gill blood vessels of ranched Southern Bluefin Tuna, Thunnus maccoyii . Based...
SNAPSHOT USA 2024: Year 6 of the Coordinated National Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multi‐contributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of speci...
Blood biomarker changes and relationships after low dose oral ketamine treatment for post-traumatic stress disorder (PTSD)NARA Subscribed
Rational Ketamine has been investigated as a treatment alternative for PTSD for the last 20 years, yet there have been limited reports of biological changes or biomarker characterisation related to treatment. Objectives To address this significant gap, this study analysed blood samples from 25 participants with PTSD who took part in an open-label 6-week trial of low dose oral ketamine treatment. Methods Serum and plasma sample...
Local and Landscape‐Level Environmental Conditions Drive Habitat Selection Across Terrestrial Mammal SpeciesNARA Subscribed
Aim Animal movements are a fundamental process affecting communities and ecosystems. Quantifying habitat selection across species and habitats is key for understanding how animals respond to environmental change. Currently, we lack comparative studies that examine how habitat selection varies across species traits and landscapes. We aim to quantify global patterns of habitat selection to help understand the fundamental drivers...
Quantifying animal movements is necessary for answering a wide array of research questions in ecology and conservation biology. Consequently, ecologists have made considerable efforts to identify the best way to estimate an animal's home range, and many methods of estimating home ranges have arisen over the past half a century. Most of these methods fall into two distinct categories of estimators that have only recently been d...
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
An ichthyological borderland: The fishfauna of Nyungwe National Park and surroundings (Rwanda, East Africa)NARA Subscribed
Nyungwe National Park (NP) is a mountainous region situated in the southwestern part of Rwanda on Congo‐Nile watershed. In spite of the high biodiversity in primates, birds and plants, no fish were reported to occur in the park, probably because of the cold temperatures of the rivers. An expedition in 2022 examined the fish diversity within the Nyungwe NP and its buffer zones. Additional sampling was performed in the main rive...
