As COVID-19 continues to spread across the world, it is increasingly important understand factors that influence its transmission. Seasonal variation driven by responses changing environment has been shown affect transmission intensity of several coronaviruses. However, impact on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) remains largely unknown, and thus seasonal a source uncertainty in forecasts SARS-CoV-2 Here we address this issue assessing association temperature,...
To elucidate climate-driven changes in leaf-out phenology and their implications for species invasions, we observed experimentally manipulated leaf out of invasive native woody plants Concord, MA, USA. Using observations collected by Henry David Thoreau (1852-1860) our own (2009-2013), analyzed timing sensitivity to temperature 43 plant species. We tested winter chilling requirements 50 exposing cut branches warm indoor temperatures (22°C) during the spring 2013. Woody are now leafing an...
Abstract Ecological forecasting provides a powerful set of methods for predicting short‐ and long‐term change in living systems. Forecasts are now widely produced, enabling proactive management many applied ecological problems. However, despite numerous calls an increased emphasis on prediction ecology, the potential to accelerate theory development remains underrealized. Here, we provide conceptual framework describing how forecasts can energize advance theory. We emphasize opportunities...
Autumn leaf senescence marks the end of growing season in temperate ecosystems. Its timing influences a number ecosystem processes, including carbon, water and nutrient cycling. Climate change is altering phenology and, as those changes continue, it will affect individual woody plants, species In contrast to spring out times, however, times remain relatively understudied. Variation among locations still poorly understood.Leaf 1360 deciduous plant at six botanical gardens Asia, North America...
Background and Aims Climate change is advancing the leaf-out times of many plant species mostly extending growing season in temperate ecosystems. Laboratory experiments using twig cuttings from woody present an affordable, easily replicated approach to investigate relative importance factors such as winter chilling, photoperiod, spring warming frost tolerance on leafing-out communities. This Viewpoint article demonstrates how results these deepen our understanding beyond what possible via...
Premise of the Study Herbarium specimens provide a robust record historical plant phenology (the timing seasonal events such as flowering or fruiting). However, difficulty aggregating phenological data from arises lack standardized scoring methods and definitions for states across collections community. Methods Results To address this problem, we report on consensus reached by an iD igBio working group curators, researchers, standards experts regarding efficient protocol data‐sharing...
Patterns of fruiting phenology in temperate ecosystems are poorly understood, despite the ecological importance for animal nutrition and seed dispersal. Herbarium specimens represent an under-utilized resource investigating geographical climatic factors affecting times within species, patterns among differences between native non-native invasive species.We examined over 15,000 herbarium specimens, collected housed across New England, found 3159 with ripe fruits, from 1849-2013. We 37 18...
Fruiting remains under-represented in long-term phenology records, relative to leaf and flower phenology. Herbarium specimens historical field notes can fill this gap, but selecting synthesizing these records for modern-day comparison requires an understanding of whether different data sources contain similar information, similar, not equivalent, fruiting metrics are comparable with one another.For 67 fleshy-fruited plant species, we compared observations made by Henry David Thoreau Concord,...
Abstract Plant phenology regulates the carbon cycle and land‐atmosphere coupling. Currently, climate models often disagree with observations on seasonal of vegetation growth, partially due to how spring onset is measured simulated. Here we use both thermal leaf area index (LAI) based indicators characterize in CMIP6 models. Although historical timing varies considerably across models, most agree that has advanced recent decades will continue arrive earlier future warming. Across Northern...
Premise of the Study To improve our understanding patterns and drivers fleshy fruit phenology, we examined sequence, across years locations, fruiting times at five botanical gardens on three continents. Methods We monitored four stages phenology for 406 temperate, fleshy‐fruited, woody plant species in 2014 2015. Key Results Across all gardens, ripe fruits were present from May to March following year, with peak durations ranging under 1 week over 150 days. Species‐level first onset dates...
Abstract Species that persist in small populations isolated by habitat destruction may experience reproductive failure. Self‐incompatible plants face dual threats of mate‐limitation and competition with co‐flowering for pollination services. Such lower pollinator visitation, increase heterospecific pollen transfer reduce the likelihood a visit results successful pollination. To understand how isolation from mates species contribute to failure fragmented habitat, we conducted an observational...
Despite their interdependence, community ecology and evolutionary biology have proven difficult to synthesize empirically in studies of assembly. This is primarily due differing temporal spatial scales ecological dynamics, ranging from broad‐scale processes like speciation environmental filtering local‐scale past present‐day niche dynamics. Phylogenetic generalized linear mixed modeling (PGLMM) offers a solution this problem, it can be used integrate through time by the evolution trait‐based...
