“…Nevertheless, potential divergent effects may exist between regions, as the relationships of FT3 and FT3:FT4 with PFHxS were more evident in urban nestlings compared to rural nestlings, while for the latter nestlings, the relationship of TT3 and PFDS was more evident. It may therefore be beneficial to further assess the regionally-specific effects of individual PFAAs (e.g., PFHxS, PFOA) on thyroid activity, immune function, and other physiological responses, especially in the context of multiple stressors to which birds are often exposed, in particular in urban environments (Suri et al, 2017;Isaksson, 2018;Marteinson and Verreault, 2020).…”

“…With the worldwide focus on biodiversity, habitat quality assessments have become a hot topic for ecologists (Cheng et al., 2022). At present, habitat quality assessment can be divided into three categories such as habitat quality assessment of individual species (Morris, 2020), habitat impact on species (Marteinson & Verreault, 2020), and regional habitat quality assessment (Zhang et al., 2020; Zheng & Li, 2022). Habitat quality assessment of a single species refers to the habitat needs of organisms and the matching relationship between the environment of neighboring plants, to clarify the distribution range and characteristics of habitats (Zhang et al., 2014), and on this basis, construct an evaluation index system and conduct a comprehensive evaluation of habitat quality (Zhang et al., 2020).…”

Habitat quality is a key expression of ecosystem ability and the basis for effective species conservation and regional ecological environment improvement. However, most studies have focused on assessing habitat quality over historical periods, ignoring the influence of coupled future development paths and climate change. The present study addresses this issue by developing a spatial‐temporal variation analysis framework for assessing habitat quality in China, which integrates the Integrated Valuation of Ecosystem Services and Trade‐offs (InVEST) model with eight Earth system coupled scenarios (SSP‐RCP). The results showed that from 2020 to 2100, and under five scenarios (SSP2‐4.5, SSP3‐7.0, SSP4‐6.0, SSP5‐3.4, and SSP5‐8.5), habitat quality was generally stable and high, while under three scenarios (SSP1‐1.9, SSP1‐2.6, and SSP4‐3.4), it decreased. The SSP2‐4.5 scenario was significantly better than the SSP4‐3.4 scenario. In all scenarios, the influences of different development patterns on China's ecologically fragile areas were obvious and serious. In 2030 and 2060, the spatial distribution patterns of habitat degradation and habitat quality had similar characteristics. High habitat degradation values were mostly distributed east of the Heihe‐Tengchong Line, while low values were mainly distributed in the arid zone. The mean habitat degradation ranged between 0.0226 and 0.0302, and the degradation degree was relatively light. The habitat quality index mean was 0.5120–0.5376, indicating that the overall habitat quality was at the medium level. This study provides a potential ecological protection baseline for China based on habitat protection and provides an important reference for China's sustainable development.

“…Nonetheless, replacing aquatic diets with anthropogenic diets has also been linked to adverse outcomes, including declining population density despite gulls laying larger eggs [80], reduced brood size [81], lower nestling body mass [82] and decreased long-term reproductive success [83]. Foraging on rubbish and at landfills is also linked to greater exposure to heavy metals [84,85], contaminants like flame-retardants [86][87][88], pathogens ( [89,90] but see [91]) and harmful non-digestible items such as plastic and broken glass [92,93], which could all lead to adverse reproductive success or survival [94][95][96][97].…”

Short-term dietary changes are reflected in the cerebral content of adult ring-billed gulls

Omega-3 long-chain polyunsaturated fatty acids (n3-LCPUFAs) are produced primarily in aquatic ecosystems and are considered essential nutrients for predators given their structural role in vertebrates’ cerebral tissues. Alarmingly, with urbanization, many aquatic animals now rely on anthropogenic foods lacking n3-LCPUFAs. In this study undertaken in Newfoundland (Canada), we tested whether recent or longer term diet explains the cerebral fatty acid composition of ring-billed gulls ( Larus delawarensis ), a seabird that now thrives in cities. During the breeding season, cerebral levels of n3-LCPUFAs were significantly higher for gulls nesting in a natural habitat and foraging on marine food (mean ± s.d.: 32 ± 1% of total identified fatty acids) than for urban nesters exploiting rubbish (27 ± 1%). Stable isotope analysis of blood and feathers showed that urban and natural nesters shared similar diets in autumn and winter, suggesting that the difference in cerebral n3-LCPUFAs during the breeding season was owing to concomitant and transient differences in diet. We also experimentally manipulated gulls’ diets throughout incubation by supplementing them with fish oil rich in n3-LCPUFAs, a caloric control lacking n3-LCPUFAs, or nothing, and found evidence that fish oil increased urban nesters’ cerebral n3-LCPUFAs. These complementary analyses provide evidence that the brain of this seabird remains plastic during adulthood and responds to short-term dietary changes.
