Although some species can see the ultraviolet (UV) spectrum, the mentioned studies did not take into account UV reflectance when characterizing bird plumage. This study aimed to use a recent database of the colorfulness in passerines that incorporated the UV spectrum to compare bird colorfulness and other traits between urban parks and rural areas in Central-East Argentina. Birds in urban parks were surveyed in 51 parks in 6 cities during breeding and non-breeding seasons. A list of Passeriformes species from parks was created, and a list of urban avoider species was created from the bibliography. Species traits were body mass, clutch size, migratory status, nesting site, diet and habitat breadth, and plumage colorfulness. A total of 85 species were detected in the regional pool, of which 30 species were detected in urban parks. Bird species present in urban parks were more colorful than bird species only present in rural areas. In addition, bird presence in urban parks was positively related to their regional frequency and diet breadth. Moreover, urban presence was related to nesting on trees and buildings, whereas species not present in urban parks nested on the ground. The results obtained showed that bird color is significantly associated with presence of bird species in urban parks.</p></div>","PeriodicalId":51311,"journal":{"name":"Avian Research","volume":"15 ","pages":"Article 100161"},"PeriodicalIF":1.8,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2053716624000045/pdfft?md5=9641f9ccd3bbbc28d1a42665792106d0&pid=1-s2.0-S2053716624000045-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139892941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The availability of food resources in the habitat is critical and varies within water levels. Although the water-level fluctuations in Poyang Lake have been extremely variable interannually in recent years, the wintering waterbird populations have remained relatively stable. Hence, the mechanism of maintaining the stability is worth exploring. This study aimed to compare the distribution of vegetation and herbivorous waterbirds in 2015–2016 and 2016–2017, focusing on three shallow sub-lakes and one main lake are. The results showed that the emergence of tubers and the growth of <em>Carex</em> spp. provided a continuous food supply and habitat for wintering waterbirds with a gradual decline in the water level. Shallow sub-lakes supported almost all of the tuber-eating waterbirds (1.42–1.62 × 10⁵) and most geese (1.34–1.53 × 10⁶). However, the main lake area, covered with <em>Persicaria hydropiper</em>, did not provide adequate and accessible food. This resulted in almost no distribution of tuber-eating waterbirds, with only a few geese congregating in early winter. Our results demonstrated that the shallow sub-lakes under human control provided a different environment from the main lake and are key to sustaining the successful wintering of hundreds of thousands of migratory waterbirds in Poyang Lake. Therefore, we recommend refining the anthropogenic management of the shallow sub-lakes to regulate the water level to ensure the carrying capacity of Poyang Lake.</p></div>","PeriodicalId":51311,"journal":{"name":"Avian Research","volume":"15 ","pages":"Article 100178"},"PeriodicalIF":1.8,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2053716624000215/pdfft?md5=6e402b0f606702d2b60f6ac6b3aad45e&pid=1-s2.0-S2053716624000215-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141083961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Irrespective of their protection status, these habitats may be threatened by organic matter accumulation, progressively leading to structural homogenization and habitat succession towards woodland. Managers prevent excessive litter build-up with various interventions opening-up the reedbeds, such as grazing, which may be detrimental or suitable for some reed bird species. We assessed the effects of extensive grazing by horses and its cessation in the medium and long terms on reedbed structure, and the consequences on reed-nesting songbird densities in Estagnol Nature Reserve, a protected wetland near the French Mediterranean coast. We compared reedbed structural features between grazed, newly ungrazed and old-ungrazed plots. During nine years, we censused four songbird species in spring and collected water level data in the same survey plots. Grazing reduced reedbed extent, rejuvenated the vegetation with more short green stems on a thinner litter, and produced higher structural heterogeneity and discontinuity compared to long-lasting non grazing. Newly ungrazed plot showed intermediate effects. All surveyed songbird total densities were similar among plots while species numbers and densities differed. Grazed reedbed was more attractive to Moustached Warblers (<em>Acrocephalus melanopogon</em>) and Great Reed Warblers (<em>Acrocephalus arundinaceus</em>), likely due to the large edges and the high vegetation structural heterogeneity. However, Moustached Warblers were more negatively affected by higher water level in grazed reedbed, presumably because flooding prevents litter foraging. The newly ungrazed reedbed was not preferred by any species. All warbler species were found under low density in the old-ungrazed reedbed, where Reed Buntings (<em>Emberiza schoeniclus</em>) were exclusively found. Food availability related to thick litter layer may explain this predilection. Common Reed Warblers (<em>Acrocephalus scirpaceus</em>) were found everywhere in similar densities. We conclude that reedbed management by extensive horse grazing and also its long-term cessation may benefit several songbird species. Within a context of wetland degradation and disappearance, both management strategies are useful to establish and maintain suitable habitats for reed-nesting songbird communities.</p></div>","PeriodicalId":51311,"journal":{"name":"Avian Research","volume":"15 ","pages":"Article 100182"},"PeriodicalIF":1.8,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2053716624000252/pdfft?md5=0940a354defe6e6e6409f0b50a26ba07&pid=1-s2.0-S2053716624000252-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141097373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The “context-dependence hypothesis” posits that female extra-pair mate choice has plasticity in response to environmental conditions, and therefore magnitude of female genetic benefits from EPP depends on the environmental variation. Furthermore, chronic heavy metal pollution can cause adverse effects on fitness-related traits of wild birds. However, few studies were available on the interactions between heavy metal pollution and EPP. We selected an area that was contaminated by heavy metals for more than 60 years (Baiyin, BY), a relatively unpolluted area (Liujiaxia, LJX), and Tree Sparrows (<em>Passer montanus</em>) as study species to explore the response of female extra-pair mate choice and genetic benefits from EPP to heavy metal pollution in socially monogamous birds. The relatedness between social mates and extra-pair mates was investigated. Additionally, we compared the body size and heterozygosity of extra-pair offspring (EPO), within-pair offspring (WPO), social males and extra-pair males from the two Tree Sparrow populations. We found that at BY, female Tree Sparrows tended to choose extra-pair males with larger body size and lower genetic similarity, thereby producing higher heterozygosity and larger body size of EPO compared with those of WPO. However, no similar phenomenon was observed in the Tree Sparrow population from LJX. In addition, there was a significant interaction between population and paternity in the analyses of the fitness-related traits, suggesting that environmental variation could affect female genetic benefits from EPP. This study confirmed the existence of presumed interactions between environmental pollution and EPP within the natural population of socially monogamous Tree Sparrows. Our findings shed lights on the possible effects of long-term environmental stress on mating system in wild birds.</p></div>","PeriodicalId":51311,"journal":{"name":"Avian Research","volume":"15 ","pages":"Article 100203"},"PeriodicalIF":1.6,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S205371662400046X/pdfft?md5=329ca4f6bc79b5dba92a9f1959860881&pid=1-s2.0-S205371662400046X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142083174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, we tried to examine the process of hindlimb ossification and its molecular regulation by using an animal model—Japanese Quail (<em>Coturnix japonica</em>). We selected four critical stages (Embryo Day: E6, E8, E12 and E16) of skeletal development of embryonic quails for hindlimb skeleton staining to show the process of endochondral ossification and to examine the molecular regulation of endochondral osteogenesis by RNA-Seq analysis. The results showed that ossification became increased with embryonic development and most hindlimb was ossified before hatching. RNA-Seq analysis revealed that various signaling pathways were involved with endochondral ossification with thyroid hormone signaling and WNT signaling pathway particularly enriched. Moreover, the expression levels of 42 genes were continuously upregulated and 14 genes were continuously downregulated from E6 to E16. The present study might provide new insights into complex molecular mechanisms in regulation of endochondral ossification.</p></div>","PeriodicalId":51311,"journal":{"name":"Avian Research","volume":"15 ","pages":"Article 100152"},"PeriodicalIF":1.8,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2053716623000786/pdfft?md5=b2b860372c46243ccd63762f08e37150&pid=1-s2.0-S2053716623000786-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138562871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
