Bayesian stable isotope mixing models
(2013)In this paper, we review recent advances in stable isotope mixing models (SIMMs) and place them into an overarching Bayesian statistical framework, which allows for several useful extensions. SIMMs are used to quantify the ... -
Best practices for use of stable isotope mixing models in food web studies
(2014)Stable isotope mixing models are increasingly used to quantify consumer diets, but may be misused and misinterpreted. We address major challenges to their effective application. Mixing models have increased rapidly in ... -
Capture heats up sharks
(2022)Catch-and-release fishing is an important component of ecotourism industries and scientific research worldwide, but its total impact on animal physiology, health and survival is understudied for many species of fishes, ... -
The consequences of unidentifiable individuals for the analysis of an animal social network
(2015)Social network analysis is pervasive in understanding animal social systems, and provides information about how individuals vary in their social strategies. Many long-term studies comprising uniquely marked individuals ... -
Cooperation and the evolution of intelligence
(2012)The high levels of intelligence seen in humans, other primates, certain cetaceans and birds remain a major puzzle for evolutionary biologists, anthropologists and psychologists. It has long been held that social interactions ... -
Endothermy makes fishes faster but does not expand their thermal niche
(Functional Ecology, 2021-06-30)Regional endothermy has evolved several times in marine fishes, and two competing hypotheses are generally proposed to explain the evolutionary drivers behind this trait: thermal niche expansion and elevated cruising speeds. ... -
Snake venom potency and yield are associated with prey-evolution, predator metabolism and habitat structure
(PubMed Central, 2019)Snake venom is well known for its ability to incapacitate and kill prey. Yet, potency and the amount of venom available varies greatly across species, ranging from the seemingly harmless to those capable of killing vast ... -
Stable isotopes are quantitative indicators of trophic niche
(Wiley, 2019)Hette-Tronquart (2019, Ecol. Lett.) raises three concerns about our interpretation of stable isotope data in Sheppard et al. (2018, Ecol. Lett., 21, 665). We feel that these concerns are based on comparisons that are ... -
Trophic adaptability shapes isotopic niche of the resident fish Aphanius fasciatus across lagoon habitats
(Elsevier BV, 2022)Coastal lagoons are characterized by high habitat heterogeneity where natural habitats coexist with artificial ones, historically set up to support human activities. Increasing anthropogenic pressure may lead to progressive ... -
Validation and use of a parametric model for projecting cystic fibrosis survivorship beyond observed data: a birth cohort analysis
(BMJ Group, 2011-07-22)Background: The current lifetable approach to survival estimation is favoured by CF registries. Recognising the limitation of this approach, we examined the utility of a parametric survival model to project birth cohort ... -
Vegetated Habitats Trophically Support Early Development Stages of a Marine Migrant Fish in a Coastal Lagoon
(2020)Understanding the trophic ecology of early developmental stages of commercial fish species migrating between sea and coastal lagoons is crucial to effective management of nursery habitats and resulting resources. While ...
