The mechanisms of phenology: the patterns and processes of phenological shifts

open access: yesEcological Monographs, 2018
AbstractSpecies across a wide range of taxa and habitats are shifting phenological events in response to climate change. While advances are common, shifts vary in magnitude and direction within and among species, and the basis for this variation is relatively unknown. We examine previously suggested patterns of variation in phenological shifts in order

Flight of the dragons: a global review of migration in Odonata

open access: yesBiological Reviews, EarlyView.
ABSTRACT Insects are the most abundant and ecologically important animal migrants. Yet, we know relatively little about the patterns and processes underlying insect migration. Dragonflies (Anisoptera) and damselflies (Zygoptera) comprise the ancient insect order Odonata, whose ancestors were the first organisms to fly on Earth.

Larval phenology of Hemigrapsus sanguineus, an invasive species

open access: yes, 2020
We modelled the larval phenology of the invasive crab Hemigrapsus sanguineus along the Atlantic coast of North America and North Europe. The phenology was computed from laboratory data on survival and duration of larval development, temperature and ...

Spatiotemporal Variation Characteristics of Extreme Precipitation in Henan Province Based on RClimDex Model

open access: yesAtmosphere
Global warming has led to an increasing frequency and intensity of extreme precipitation events worldwide. The extreme precipitation of Henan Province in central China usually occurs in summer, with the climate transition from the northern subtropical to

Counting cases, conserving species: addressing highly pathogenic avian influenza in wildlife

open access: yesBiological Reviews, EarlyView.
ABSTRACT Highly pathogenic avian influenza (HPAI) has become a critical threat to wildlife, shifting from a seasonal epizootic to a persistent, year‐round panzootic with global consequences. Here, we summarise the origin, evolutionary mechanisms, and expanding host range of the current H5N1 virus (clade 2.3.4.4b) and assess its impact on wildlife. Over

Environmental change and the phenology of European aphids

open access: yes, 2007
Aphids, because of their short generation time and low developmental threshold temperatures, are an insect group expected to respond particularly strongly to environmental changes. Forty years of standardized, daily data on the abundance of flying aphids

Trade‐offs in avian parental care: a review of theory and meta‐analysis of brood size manipulations

open access: yesBiological Reviews, EarlyView.
ABSTRACT The selective forces shaping parental care have been studied for over 50 years. While theoretical and experimental work has yielded qualitative progress, the large body of empirical work testing predictions about parental investment based on life‐history trade‐offs has yet to be synthesized.
