Abstract

Advancing Plant Phenology Causes an Increasing Trophic Mismatch in an Income Breeder Across a Wide Elevational Range

Highlights

Rising temperatures as a consequence of climate change have led to an overall spring phenology advancement for many organisms across the Northern Hemisphere (Menzel 2003, Cleland et al 2007, Roberts et al 2015)
Temporal changes in parturition date A slight trend toward more advanced parturition dates through time was found at different scales and elevational intervals
We found a consistent advance toward earlier parturition dates across all scales and most elevational ranges that could be associated with a response to climate change

Summary

Introduction

Rising temperatures as a consequence of climate change have led to an overall spring phenology advancement for many organisms across the Northern Hemisphere (Menzel 2003, Cleland et al 2007, Roberts et al 2015). Phenological mismatches may occur if a different magnitude of response disrupts previously synchronous trophic interactions (Visser et al 1998, Koh et al 2004). Demography and population viability (Brook et al 2009, Bronson 2009, Miller-Rushing et al 2010, Usui et al 2017). For plant consumers, such as large herbivores, breeding timing is the period of peak energy demand for females which should match the optimal time in terms of resource availability (Post et al 2003, H€am€al€ainen et al 2017). A mismatch can reduce annual reproductive success (Clutton-Brock et al 1987, Plard et al 2014, Paoli et al 2018) and future reproductive performance of both females and newborns (Clutton-Brock et al 1983, Festa-Bianchet et al 2000)
