In reptiles, reproductive maturity is often determined by size rather than age. Consequently, growth early in life may influence population dynamics through effects on generation time and survival to reproduction. Because reproductive phenology and pre- and post-natal growth are temperature-dependent, environmental conditions may induce multi-species cohort effects on body size in sympatric reptiles. I present evidence of this using ten years of neonatal size data for three sympatric viviparous snakes, Dekay’s Brownsnakes (Storeria dekayi), Red-bellied...
Objectives: Hair (i.e., pelage/fur) is a salient feature of primate (including human) diversity and evolution—serving functions tied to thermoregulation, protection, camouflage, and signaling—but wild primate pelage evolution remains relatively understudied. Specifically, assessing multiple hypotheses across distinct phylogenetic scales is essential but is rarely conducted. We examine whole body hair color and density variation across Indriidae (Avahi, Indri, Propithecus)—a lineage that, like humans, exhibits vertical posture (i.e., their whole bodies are vertical to the sun). Materials...
Data for Land-sea linkages depend on macroalgal species, predator invasion history in a New Zealand archipelagoStephanie Borrelle, Holly Jones & Lyndsay Rankin
Seabirds on islands create a circular seabird economy - whereby they feed in the ocean, transport marine-derived nutrients onshore to their breeding colonies, and then seabird-derived nutrients run off into the ocean, enriching nearshore ecosystems. Invasive predators reduce seabird colonies and nutrient subsidies; thus, predator eradication is critical for restoring seabird islands. Few studies have linked nearshore marine recovery to terrestrial ecosystem attributes and none have in temperate zones. Here, we tested the influence of...
Supplementary data, code, and information for ‘Interhemispheric antiphasing of neotropical precipitation during the past millennium’ (PNAS, Steinman et al. 2022)B.A. Steinman, N. Stansall, M.E. Mann, C.A. Cooke, M.B. Abbott, M. Vuille, B.W. Bird, M.S. Lachniet & A. Fernandez
Uncertainty about the influence of anthropogenic radiative forcing on the position and strength of convective rainfall in the Intertropical Convergence Zone (ITCZ) inhibits our ability to project future tropical hydroclimate change in a warmer world. Paleoclimatic and modeling data inform on the timescales and mechanisms of ITCZ variability; yet a comprehensive, long-term perspective remains elusive. Here, we quantify the evolution of neotropical hydroclimate over the pre-industrial past millennium (850 to 1850 CE) using a synthesis...
High-resolution climate simulations using the Model for Prediction Across Scales - Atmosphere (MPAS-A; version 5.1)Allison Michaelis, Roger Turnau, Gary Lackmann & Walter Robinson
We present multi-seasonal simulations representative of present-day and future environments using the global Model for Prediction Across Scales – Atmosphere (MPAS-A) version 5.1 with high resolution (15 km) throughout the Northern Hemisphere. We select 10 simulation years with varying phases of El Niño–Southern Oscillation (ENSO) and integrate each for 14.5 months. We use analyzed sea surface temperature (SST) patterns for present-day simulations. For the future climate simulations, we alter present-day SSTs by applying monthly-averaged temperature...
