5 results for “onset of spring”
Data from ONSET OF EARLY SPRING ACTIVITY BY AMPHIBIANS IN ITHACA, NEW YORK, USA
<p>This dataset was generated by conducting a search of all verifiable, research grade observations with photographs of amphibians (Category = Amphibia) in Ithaca, New York for the period 1 February to 30 April for the years 2016–2024. We constrained the search to an area within a 5 km radius of Cornell University, Ithaca, New York, USA (42.45° N, 76.48° W). The data output was modified to remove observer names as well as datafields that were extraneous to the analysis.</p>
Data from: Onset of autumn shapes the timing of birth in Pyrenean chamois more than onset of spring
1. In seasonal environments, birth dates are a central component for a species' life history, with potential long-term fitness consequences. Yet our understanding of selective pressures of environmental changes on birth dates is limited in wild mammals due to the difficulty of data collection. In a context of rapid climate change, the question of a possible mismatch between plant phenology and birth phenology also remains unanswered for most species. 2. We assessed whether and how the timing of birth in a mountain mammal (isard, Rupicapra pyrenaica) tracked changes in plant growing season, accounting for maternal traits, individual heterogeneity, and population density. We not only focused on spring conditions but also assessed to what extent onset of autumn can be a driver of phenological biological events and compared the magnitude of the response to the magnitude of the environmental changes. We relied on a 22-year study based on intensively monitored marked individuals of known age. 3. Births were highly synchronized (80% of kids born within 25 days) and highly repeatable (84%; among-females variation of 9.6 days, withinfemale variation of 4.2 days). Individual phenotypic plasticity allows females to respond rapidly to inter-annual changes in plant phenology but did not prevent the existence of a mismatch: a 10-day advance in the autumn or spring plant phenology led to 3.9 and 1.3 days advance in birth dates, respectively. 4. Our findings suggest that plant phenology may act as a cue to induce important stages of the reproductive cycle (e.g., conception and gestation length), subsequently affecting parturition dates, and stressed the importance of focusing on long-term changes during spring for which females may show much lower adaptive potential than during autumn. These results also question the extent to which individual plasticity along with high heterogeneity among individuals will allow species to cope with demographic consequences of climate changes.
