“…That drought affected male but not female breeding readiness suggests possible desynchronization of breeding among sexes. Such desynchronization of male and female breeding physiology might result in reduced reproductive success and contribute to the decline of populations (Visser et al 1998, Kucheravy et al 2021, Inouye 2022, Williams et al 2022.…”

Climate change is expected to increase the prevalence and severity of extreme weather events like drought. For many opportunistically breeding tropical bird species, precipitation serves as a primary cue for onset of breeding, and sustained drought can have major impacts on reproductive fitness. The physiological effects of drought are poorly understood, but understanding physiological responses can help resolve the mechanisms underlying effects of drought on population demography. We used physiological data collected on a year-round breeding New Guinea endemic passerine, the White-shouldered Fairywren (Malurus alboscapulatus), during years with persistent rainfall and during the 2015-2016 El Niño drought event to assess patterns of breeding readiness, body condition, and molt. Many males lost their cloacal protuberances, a sperm storage organ they typically maintain year-round, during the drought period. Body molt, which also occurs year-round in this species, was higher in males during the drought period. Using a sliding-window statistical model approach, we identified a critical precipitation window of 0-40 days prior to capture for cloacal protuberance volume and a window of 8-53 days for molt, with lower precipitation associated with smaller cloacal protuberances and greater molt. Plasma androgens were predictive of variation in male cloacal protuberance volume and molt, thus potentially mediating transitions between life-history stages in response to environmental conditions. Female molt, androgens, and male mass varied with photoperiod, with longer but decreasing day lengths characteristic of the austral summer associated with increasing molt and decreasing androgens. Collectively, our results indicate the potential for photoperiod to cue some life-history stages, whereas reduced rainfall impacts male but apparently not female reproductive physiology and readiness to breed. Improving our understanding of environmental regulation of life-history transitions in tropical taxa is essential for identifying which taxa are most at risk under a changing climate. La sécheresse perturbe la préparation à la nidification tout au long de l'année chez un passereau tropicalRÉSUMÉ. On prévoit que les changements climatiques augmenteront la prévalence et la gravité des phénomènes météorologiques extrêmes tels que la sécheresse. Pour de nombreuses espèces d'oiseaux tropicaux qui nichent de façon opportuniste, les précipitations sont le principal indice du début de la nidification, et une sécheresse prolongée peut avoir des répercussions importantes sur la capacité de reproduction. Les effets physiologiques de la sécheresse sont mal connus, mais la compréhension des réponses physiologiques peut aider à résoudre les mécanismes sous-jacents aux effets de la sécheresse sur la démographie des populations. Nous avons utilisé les données physiologiques recueillies chez un passereau endémique de Nouvelle-Guinée se reproduisant toute l'année, le Mérion à épaulettes (Malurus alboscapulatus), au cours d'années avec des précipitations ...

“…Apart from climate change‐induced alterations of signals, long‐term environmental changes can also affect the phenology of signalling displays. It is well‐recognized that rising temperatures and changes in precipitation patterns have resulted in phenological advancement for many organisms (reviewed in Inouye, 2022). Such species‐specific changes in phenology are likely to cause temporal mismatches among signallers, target and non‐target receivers paralleling those described for other types of species interactions (e.g.…”

Eavesdropping predators, parasites and parasitoids exploit signals emitted by their prey and hosts for detection, assessment, localization and attack, and in the process impose strong selective pressures on the communication systems of the organisms they exploit. Signallers have evolved numerous anti‐eavesdropper strategies to mitigate the trade‐off between the costs imposed from signal exploitation and the need for conspecific communication. Eavesdropper strategies fall along a continuum from opportunistic to highly specialized, and the tightness of the eavesdropper–signaller relationship results in differential pressures on communication systems. A wide variety of anti‐eavesdropper strategies mitigate the trade‐off between eavesdropper exploitation and conspecific communication. Antagonistic selection from eavesdroppers can result in diverse outcomes including modulation of signalling displays, signal structure, and evolutionary loss or gain of a signal from a population. These strategies often result in reduced signal conspicuousness and in decreased signal ornamentation. Eavesdropping enemies, however, can also promote signal ornamentation. While less common, this alternative outcome offers a unique opportunity to dissect the factors that may lead to different evolutionary pathways. In addition, contrary to traditional assumptions, no sensory modality is completely ‘safe’ as eavesdroppers are ubiquitous and have a broad array of sensory filters that allow opportunity for signal exploitation. We discuss how anthropogenic change affects interactions between eavesdropping enemies and their victims as it rapidly modifies signalling environments and community composition. Drawing on diverse research from a range of taxa and sensory modalities, we synthesize current knowledge on anti‐eavesdropper strategies, discuss challenges in this field and highlight fruitful new directions for future research. Ultimately, this review offers a conceptual framework to understand the diverse strategies used by signallers to communicate under the pressure imposed by their eavesdropping enemies.

“…Vegetation phenology is an important and integrative proxy that characterizes the Earth system dynamics and is the key to understanding how atmosphere‐biosphere‐hydrosphere interactions respond to climate change and human activities (Fu et al, 2020 ; Inouye, 2022 ). Phenology has been a prominent diagnostic proxy as well as an input in prognostic models that is widely used in areas such as food security (Alemu & Henebry, 2016 ; Gao & Zhang, 2021 ; Gray, Friedl, et al, 2014 ; Lobell et al, 2008 ), frost hazard (Dai et al, 2013 ; Ge et al, 2013 ; Hänninen, 2006 ), drought (de Beurs & Henebry, 2008 ), forest fire risk (Bison et al, 2022 ), landscape dynamics, climate change (Brown et al, 2017 ; Friedl et al, 2014 ; Jeganathan et al, 2014 ; Jin et al, 2019 ), biogeochemical cycling (Gray, Frolking, et al, 2014 ; Piao et al, 2019 ).…”

Vegetation phenology has been viewed as the nature's calendar and an integrative indicator of plant-climate interactions. The correct representation of vegetation phenology is important for models to accurately simulate the exchange of carbon, water, and energy between the vegetated land surface and the atmosphere. Remote sensing has advanced the monitoring of vegetation phenology by providing spatially and temporally continuous data that together with conventional ground observations offers a unique contribution to our knowledge about the environmental impact on ecosystems as well as the ecological adaptations and feedback to global climate change. Land surface phenology (LSP) is defined as the use of satellites to monitor seasonal dynamics in vegetated land surfaces and to estimate phenological transition dates. LSP, as an interdisciplinary subject among remote sensing, ecology, and biometeorology, has undergone rapid development over the past few decades. Recent advances in sensor technologies, as well as data fusion techniques, have enabled novel phenology retrieval algorithms that refine phenology details at even higher spatiotemporal resolutions, providing new insights into ecosystem dynamics. As such, here we summarize the recent advances in LSP and the associated opportunities for science applications. We focus on the remaining challenges, promising techniques, and emerging topics that together we believe will truly form the very frontier of the global LSP research field.
