“…The niche concept itself dates back to Grinnel (1917) and is now widely applied in bioecology and sociology ( Popielarz and Neal 2007 ). Segregation can be found on different dimensions ( Pianka 1981 ): there can be temporal niches (for example, Carothers and Jaksic 1984 ; Kronfeld-Schor and Dayan 2003 ; Castro-Arellano and Lacher 2009 ; Hayward and Slotow 2009 ), spatial niches ( Hagen et al. 2007 ), trophic niches ( Dammhahn et al.…”

Stopover niche utilization of birds during migration has not gained much attention so far, since the majority of the studies focuses on breeding or wintering areas. However, stopover sites are crucial for migratory birds. They are often used by a multitude of species, which could lead to increased competition. In this work, we investigated niche use of 8 migratory and closely related Emberiza bunting species at a stopover site in Far East Russia, situated on the poorly studied East Asian flyway. We used bird ringing data to evaluate morphological similarity as well as niche overlap on the trophic, spatial, and temporal dimension. Bill morphology was used as a proxy for their trophic niche. We were able to prove that a majority of the species occupies well-defined stopover niches on at least one of the dimensions. Niche breadth and niche overlap differ between spring and autumn season with higher overlap found during spring. Morphological differences are mostly related to overall size and wing pointedness. The temporal dimension is most important for segregation among the studied species. Furthermore, all species seem to exhibit a rather strict and consistent phenological pattern. Their occurrence at the study site is highly correlated with their geographic origin and the length of their migration route. We assume that buntings are able to use available resources opportunistically during stopover, while trying to follow a precise schedule in order to avoid competition and to ensure individual fitness.

“…Connectivity is apparent at scales from the centimetre-scale movement of rotifers to food patches (Ignoffo et al 2005) to longdistance bird migration (Alerstam et al 2007). From a conceptual point of view, connectivity is crucial in a broad spectrum of contexts from conservation (Jones et al 2007) and pest and disease vector management (Grilli & Bruno 2007) to gene flow (Boulet et al 2007), the generation of species diversity (Genner et al 2007), the regulation of competitive advantage (Hagen et al 2007) and metapopultion dynamics (Hanski 1998).…”

Connectivity links habitats in space and time. It is a key process that facilitates many life-history functions of myriad species in a variety of contexts over a wide range of scales. Perhaps its most obvious application is to the multifaceted linkages among the diverse habitat units comprising ecosystem complexes like the coastal ecosystem mosaic (CEM) -the tightly interlinked coastal, estuarine, wetland and freshwater habitats at the interface of land and sea. The ability to utilise this diversity of connected habitats is integral to the life histories of a broad spectrum of organisms, with connectivity between habitats being crucial to important functions like nursery utilisation. Although connectivity is an obvious feature of the CEM, investigation of its implications has largely been restricted to the migration of organisms. However, connectivity has much broader conceptual relevance. It is a pervasive and multifaceted process affecting and enabling the lives of organisms over the full range of conceptual scales, with ecosystem components connected by a diversity of factors, including physical and biological translocation of nutrients, ontogenetic, life history, spawning and feeding migrations, food-web dynamics, predator-prey interactions, and many more. All of these play crucial roles in structuring biological populations, communities and assemblages, and in driving the biological processes that support them. Moreover, connectivity is a prominent and necessary component of ecological concepts, ranging from estuarine dependence and metapopulation dynamics to foraging arena theory. Considering connectivity as a multifaceted process leads to specific hypotheses about the functioning of the CEM and similar ecosystem complexes.

“…For example, lesser prairie chickens generally occupy habitats containing mid-and tall grasses throughout the year (Haukos & Zavaleta, 2016;Jones, 1963) and conversion of grassland to cropland is often attributed to declines in abundance of both lesser and greater prairie chickens (Hagen et al, 2004;Johnson et al, 2020). However, there is evidence that lesser prairie chickens use croplands, particularly during winter months, and presence of some cropland in the landscape can increase abundance of this species, likely through providing winter forage (Hagen et al, 2007;Ross et al, 2016b). Lesser prairie chickens also benefit from landscape heterogeneity, so the presence of cropland may additionally help create habitat mosaics that support the different landscape types F I G U R E 4 Examples of observed landscapes surrounding lesser prairie chicken (LEPC), greater prairie chicken (GRPC), northern bobwhite (NOBO), and ring-necked pheasant (RNEP) survey routes that contained grassland configured for optimal abundance for each species of interest based on the results of edge density (ED) models.…”
