Aapa mires are used by specialist breeding migratory waterbirds (particularly Broad-billed Sandpiper <i>Calidris falcinellus</i>, Jack Snipe <i>Lymnocryptes minimus</i>, Taiga Bean Goose <i>Anser fabalis</i> and Pintail <i>Anas acuta</i>) and support high densities of other nesting wader species (Wood Sandpiper <i>Tringa glareola</i>, Spotted Redshank <i>Tringa erythropus</i>, Ruff <i>Calidris pugnax</i>, Common Snipe <i>Gallinago gallinago</i>, Curlew <i>Numenius arquata</i> and Whimbrel <i>Numenius phaeopus</i>) compared with other peatland landforms. Remote sensing, palynology and peat stratigraphy studies confirm rapid and massive loss of aapa mires through recent drainage, but now also through climate change. Botanists report that recent warming has caused enhanced successional expansions in ombrotrophic raised mire vegetation to engulf aapa mires, destroying their unique surface and nutrient characteristics. As the waterbird species associated with aapa mires cannot survive on acidic base-poor raised mire systems, this ecological change places their populations in jeopardy. While acknowledging the need to reduce climate change through other means, these changes prioritize the need for international cooperation to extend and improve site-safeguarding of intact aapa mires and restoration of damaged aapa mires, as well as effective conservation of affected avian species throughout their full annual cycle to safeguard them, aapa mires and their associated bird communities for future generations. The case regarding aapa mires highlights the need to establish new mechanisms to create cohesive networks of protected areas for special habitats that are of disproportional importance to key avian populations and other wetland species that may not be adequately represented in current site-safeguard networks.</p>","PeriodicalId":13254,"journal":{"name":"Ibis","volume":"167 2","pages":"591-598"},"PeriodicalIF":1.8,"publicationDate":"2024-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ibi.13385","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143645986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such coloration can differ among body regions, with some regions presenting conspicuous coloration, while others are more discreet. Plumage coloration can also be associated with species' life-history traits, such as diet, habitat and nest type. Despite the relevance to ecology and evolution of bird plumage coloration, little is known regarding the relationship between the coloration of ventral and dorsal regions of bird species, especially in the Atlantic Forest, a global hotspot of biodiversity. Here we assessed plumage brightness and saturation of the dorsal and ventral regions of Atlantic Forest birds, and analysed the differences in coloration and colour variability between the regions. We also tested whether sex dichromatism, nest type, diet, habitat and foraging stratum preference are related to plumage coloration. We found that dorsal regions tend to be darker, more achromatic and less variable across species when compared to ventral regions. Additionally, plumage coloration of bird species incubating in open nests is brighter than in birds from closed nests, while species with sexual dichromatism tend to present darker ventral regions. Our results bring new insights into the role of plumage coloration in Atlantic Forest bird ecology, suggesting that different evolutionary forces may act in different body regions.</p>","PeriodicalId":13254,"journal":{"name":"Ibis","volume":"167 3","pages":"765-775"},"PeriodicalIF":1.8,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144309051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because migratory songbirds tend to follow the same orientation and migration route throughout their lives, age assessment can help to distinguish individuals which have already used a route (i.e. adults) from those using it for the first time (i.e. juveniles). The presence of a significant proportion of adult individuals would suggest the presence of regular migrants in a vagrancy context. To decipher the status of two species of Siberian warblers in Europe, the Yellow-browed Warbler <i>Phylloscopus inornatus</i> and the Siberian Chiffchaff <i>P. tristis</i>, we assessed the age-ratios of (respectively) 324 and 117 individuals captured at different sites during the last decade. We compared whether the estimated age-ratios differed from those estimated in Common Chiffchaff <i>P. collybita</i>, a common and widespread breeding and migrating species in Europe, used here as a control species. With 1.8% of birds being adult (one confirmed, five probable), the vast majority of Yellow-browed Warblers occurring in Europe each autumn appear to be mostly, if not only, vagrants, implying that the species does not migrate regularly in Europe. These results are consistent with the very few spring records but still invite further research to unravel this remarkable phenomenon of large-scale vagrancy. Conversely, we estimated that 9.4% and 29.7% of Siberian Chiffchaffs captured, respectively, during migration in Sweden and on regular wintering sites in southern France are adult birds, suggesting that the species could migrate towards southern Europe to winter, using a migration route in a markedly different direction from those known previously. These results urge more research to explore the origin, selection and causes of orientation variability in songbird species at the start of their first migration.</p>","PeriodicalId":13254,"journal":{"name":"Ibis","volume":"167 3","pages":"632-645"},"PeriodicalIF":1.8,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ibi.13382","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144308612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Snow avalanches are a natural disturbance that create habitat mosaics which host unique bird communities, but their frequency and severity will probably be influenced by climate change. Ski-pistes can be considered the artificial counterpart of avalanches, and have been shown to have generally negative effects on alpine fauna. In this study, we compared the bird assemblages of these two open, linear habitats in the Italian Alps, to determine if ski-pistes could compensate for the potential loss of avalanche tracks and open habitats in the future. In the forest and treeline ecotone zones, there was little difference in abundance and diversity between avalanche tracks, ski-pistes and reference points. However, above the treeline, avalanche tracks supported greater bird diversity and were characterized by high vegetation diversity, whereas ski-pistes harboured less-abundant and less-diverse bird assemblages in a homogeneous habitat with high grass cover. Shrub-related species were negatively affected by the vegetation removal involved in the creation of ski-pistes, but occurred in suitable habitats in the avalanche tracks at lower elevations. Although ski-pistes had the most negative impacts in high-elevation assemblages, they were used by some species of alpine and low-elevation grasslands, showing that pistes could provide suitable habitats below the natural treeline, which may be of benefit to threatened grassland birds. New high-elevation ski facilities should be discouraged and the conservation potential of ski-pistes could be improved with sustainable management practices by including some important habitat elements from avalanche tracks such as small trees and shrubs.</p>","PeriodicalId":13254,"journal":{"name":"Ibis","volume":"167 3","pages":"679-694"},"PeriodicalIF":1.8,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ibi.13380","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144309190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Oviparous females can allocate energy into egg size and/or clutch size, and this allocation can vary over lifetimes, within populations and among species. However, we know little about whether investment decisions shift within breeding seasons and the factors that influence female reproductive strategies. We studied endogenous and exogenous factors associated with variation in female reproductive investment by measuring 860 eggs from 240 clutches laid by Grasshopper Sparrows <i>Ammodramus savannarum</i> between 2014 and 2019 at the Konza Prairie Biological Station in Manhattan, Kansas, USA. As the breeding season progressed, females laid smaller clutches of heavier eggs, indicating a shift in investment towards fewer but higher quality young. Females that were heavier than expected given their body size laid heavier and larger eggs, but maternal body condition was not related to clutch size. Brood parasitism by Brown-headed Cowbirds <i>Molothrus ater</i> reduced the number of Grasshopper Sparrow eggs in nests, but was unrelated to host egg size or the total number of eggs that a female incubated, implying that sparrows do not adjust investment in response to parasitism risk. Pre-laying ambient temperature and precipitation were not associated with egg size, yet females tended to lay more eggs under rainier conditions. Overall, we provide evidence that both endogenous and exogenous factors shape female reproductive investment. Understanding the flexibility of reproductive strategies in response to multiple sources of selection, and how this mediates key trade-offs that influence demographic rates, can be used in forecasting population growth of bird species affected by anthropogenic changes to breeding areas.</p>","PeriodicalId":13254,"journal":{"name":"Ibis","volume":"167 2","pages":"437-451"},"PeriodicalIF":1.8,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ibi.13379","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143646270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Migratory birds face particular challenges in shifting breeding phenology to track warmer springs, and understanding the impacts of rising spring temperatures on migratory birds' breeding is urgent. Here, we use over 4000 UK observations of Common Redstart nests, and spring temperature data from 1974 to 2020, to examine the effect of spring temperatures on laying date, clutch size and brood size. We use a sliding window approach to detect periods over which traits are most sensitive to temperature, and compare phenotypic responses to temperature over space and time with the aim of identifying causal effects of temperature and inferring the contributions of plasticity and local adaptation. We found that redstart laying date was sensitive to spring temperature from mid-April to late May, with a relatively shallow response of 1–2 days/°C that was similar across space and time, but shallower than the phenological response of many of the resource species. Over the study period, laying date has advanced by more than 11 days, which is substantially more than can be explained based on the temperature plasticity estimates we obtained. Spring temperature had a weak, but positive, impact on clutch size, but with no evidence of an effect of spatial variation in temperature. The rate of brood size reduction from hatching to fledging became more negative at higher temperatures, but after taking into account a non-significant but positive effect of temperature on brood size at hatching, there was no net effect of temperature on fledging success. Taken together, we found little evidence that higher temperatures in the UK lead to lower reproductive output.</p>","PeriodicalId":13254,"journal":{"name":"Ibis","volume":"167 2","pages":"418-436"},"PeriodicalIF":1.8,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ibi.13376","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143646247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it can be difficult to determine if a species is extinct, especially if the species has an extensive range, including being a transcontinental migrant, or is poorly known. The breeding range of the migratory Critically Endangered Slender-billed Curlew <i>Numenius tenuirostris</i> is uncertain, and the species has an extensive non-breeding range that spans central Asia, eastern Europe, the Middle East, the Mediterranean basin and the northwest African coast. There have been no incontrovertible sightings since 1995. In this time, extensive and intensive searches for the species have continued. Using an IUCN extinction probability framework, we incorporate potential threats to the species, search effort and past records (museum specimens and confirmed and unconfirmed sightings, all of which are primarily from its non-breeding range) to assess the probability of extinction. The model indicates that there is a 96.0% probability that Slender-billed Curlew is no longer extant, classing it as Extinct according to IUCN Red List guidelines. Posterior probability Bayesian extinction date estimation modelling suggests an extinction year around the time of the 1995 sighting. Although several threats to the species have been suggested, those that definitively drove the species to extinction will never be known. Other species of <i>Numenius</i> are under a range of pressures, and many are recognized as globally threatened.

Some hypotheses propose that different signals trade-off with each other, potentially due to resource limitations (‘trade-off’ or transfer hypothesis) or that these develop simultaneously to enhance communication effectiveness (‘joint evolution’ hypothesis). Alternatively, multiple cues may evolve independently to serve distinct functions or convey different information (‘multiple messages’ hypothesis). Here, we explored the interdependence between different signal modalities in manakins (Pipridae), which are known for great interspecific diversity in the degree of elaboration in courtship dance, song and plumage coloration. We also used comparative methods to explore the mode of evolution and the degree of conservatism of these signals. We found that song, plumage coloration and courtship dance evolved independently as there was no correlation between these traits. Song evolution in manakins was attracted to a single optimum and exhibited a weak phylogenetic signal in comparison with those of colour and behavioural diversity. The high support found for the speciational and κ models when analysing the multivariate estimates of trait variability suggests that these signals (especially colour and behaviour attributes) may have evolved in a punctuated manner, with large evolutionary changes at speciation events and minimal subsequent changes along the branches. Our results show that song, colour and dance diversity are each associated (or marginally associated) with different ecological factors, indicating that sexual signals in manakins might convey different information and/or respond to different selection pressures. Larger species and those with lower dispersal capacity tend to exhibit higher colour richness, which in turn differed among lek categories, being higher in species with ‘classic’ leks and lower in non-lekking species. Overall, the present study supports the idea that correlation between signal modalities does not constitute a widespread pattern in songbirds.</p>","PeriodicalId":13254,"journal":{"name":"Ibis","volume":"167 2","pages":"481-497"},"PeriodicalIF":1.8,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ibi.13362","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143645955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
