Synchrony in the phenology of a culturally iconic spring flower
We examine the flowering phenology of the cultural iconic Spring Snowflake Leucojum vernum, a considerable tourist attraction, recorded from two sites in western Poland. Flowering dates at the two sites were closely correlated but about 6 days later at the more natural area. The end of flowering was associated with the start of canopy leafing. Early flowering was related to a longer flowering s...
متن کاملGlobal spatial ecology of three closely-related gadfly petrels.
The conservation status and taxonomy of the three gadfly petrels that breed in Macaronesia is still discussed partly due to the scarce information on their spatial ecology. Using geolocator and capture-mark-recapture data, we examined phenology, natal philopatry and breeding-site fidelity, year-round distribution, habitat usage and at-sea activity of the three closely-related gadfly petrels tha...
متن کاملPrecipitation impacts on vegetation spring phenology on the Tibetan Plateau.
The ongoing changes in vegetation spring phenology in temperate/cold regions are widely attributed to temperature. However, in arid/semiarid ecosystems, the correlation between spring temperature and phenology is much less clear. We test the hypothesis that precipitation plays an important role in the temperature dependency of phenology in arid/semiarid regions. We therefore investigated the in...
متن کاملSpatial distribution and ecological niches of non-breeding planktivorous petrels
According to niche theory, mechanisms exist that allow co-existence of organisms that would otherwise compete for the same prey and other resources. How seabirds cope with potential competition during the non-breeding period is poorly documented, particularly for small species. Here we investigate for the first time the potential role of spatial, environmental (habitat) and trophic (isotopic) s...
متن کاملForaging Behavior of Fishes
BACKGROUND: Small species of fish and juveniles of larger species occupy aquatic plant patches for food (Pardue 1973; Keast 1984) and protection from predators (Crowder and Cooper 1982; Savino and Stein 1989). Differences in density and morphology of plants influence foraging intensity and degree of predator avoidance (Dionne and Folt 1991; Lillie and Budd 1992; Wychera et al. 1993; Dibble, Kil...
