Wetlands make a disproportionately large contribution to global biodiversity and provide critical ecosystem services for humanity. Yet, our understanding of the cultural ecosystem services (CES) provided by wetlands remains limited, with benefits often only recognised at local scales. To address this knowledge gap, we conducted a global systematic review of wetland CES. Our synthesis addressed key questions related to the provision of CES by different types of wetlands, their economic value, their co-occurrence and associations with other ecosystem services, threats to the provision of CES by wetlands, as well as the availability and use of CES information. Based on 861 …

Shifting The Focus From Species To Individuals In Invasion Biology: Individual Differences In Jumping Behaviour, Aaron Jessop, Miguel Barbosa, Michael Morrissey

School of Biological and Marine Sciences

Dispersal is critical to population persistence, colonization and connectivity which are all critical components of invasive success. While individual propensity to disperse varies within populations, the underlying mechanisms promoting individual dispersal remain unclear. Collectively, dispersal is influenced by the environment and individual phenotype. Here we investigated individual dispersal propensity in the Trinidadian guppy, Poecilia reticulata, and related individual variation in dispersal behaviour to phenotype and social/environmental conditions. Namely, we addressed the effect of sex ratio (social/environmental factor) on the tendency for individuals to disperse across physical barriers via jumping behaviour. Jumping is vital for the dispersal of many aquatic species …

Guidelines For Protecting And Promoting Decapod Crustacean Welfare In Research, Mark Briffa Jan 2024

Guidelines For Protecting And Promoting Decapod Crustacean Welfare In Research, Mark Briffa

School of Biological and Marine Sciences

The decapod order contains ~15,000 species, including crabs, lobsters, crayfish, prawns, and shrimps. The idea that these animals might experience pain was long dismissed because they were thought to respond to noxious stimuli and tissue damage purely by nociceptive reflex—a position questioned by Sherwin (2001). Later experimental studies demonstrated that their responses were complex, long-lasting, and largely consistent with criteria for pain that had been produced initially for vertebrates (Elwood 2019). While the nature and extent of potential sentience in decapods remains an active area of research, these animals were recently recognized as sentient for the purposes of UK law, …
