The flagship species concept is based on the perceived "charisma" of species. While certain attributes have been proposed to predict charisma, support for conservation often driven by local and context-specific factors. largest hypersaline lagoon in South America has considered restoration programs after suffering from decades urban development pollution. Recently, seahorse Hippocampus reidi was reported lagoon, generating significant public attention. Inspired marketing theory, we conducted a study evaluate people's preferences various inhabiting lagoon. In choice experiment, participants were shown high-resolution photographs ten species, including seahorse, asked rank their top three preferred (most = 3, second most 2, third 1), as well least (least -3, -2, -1).

Published: March 6, 2025

Annual-cycle movements of wildlife are driven by a combination intrinsic and extrinsic factors. In urban systems, management strategies to reduce human-wildlife interactions could also alter movement distribution, with potential effects on key ecological processes such as pathogen spread. To better understand how actions interact existing spatial dynamics mediate patterns, we experimentally subjected urban-nesting yellow-legged gulls induced breeding failure via egg-oiling. We then followed their using bird-borne GPS transmitters throughout the treatment season well following annual cycle compared them tracked whose nests were not oiled, while accounting for individual temporal factors known influence patterns including sex, body size, stage. Gulls oiled had smaller breeding-season home ranges, spent more time at sites, made fewer foraging trips, traveled shorter distances than non-oiled during but season. partially migratory, individuals showing variety migratory from year-round residency long-distance migration inland centers. Although egg-oiling delayed onset post-breeding migration, remaining consistent between years regardless treatment. Antibody titres against three common pathogens varied among or characteristics.

In birds, plastic particles have been identified hundreds of and terrestrial species leading to adverse effects.

The expansion of urban areas affects wild animals in a variety ways. Why members closely-related species respond differently to urbanisation is often unclear, but an understanding the factors that lead habitat use or avoidance will have important implications for conservation. Previous research has suggested habitats could favour larger-brained, behaviourally flexible species, which can more readily cope with novel challenges imposed by urbanisation. However, opportunity colonise areas, and similarities between species’ natural habitats, may also explain use. We phylogenetic path analysis investigate promote breeding foraging gull subfamily, group several urbanised species. While we find little evidence support relationship brain size foraging, reveal indirect breeding: cliff-nesting relatively larger brains these are likely breed areas. show cliff nesting gulls derived trait therefore reflect plasticity choice, facilitating buildings as sites.
