Historical case study of a transfer experiment that demonstrated the importance of the estuarine ecosystem for the survival of Chinook salmon (Oncorhynchus tshawytscha) at the Campbell River estuary, British Columbia, Canada

open access: yesJournal of Fish Biology, EarlyView.
Abstract Estuary dependence to the survival of Chinook salmon was investigated at the Campbell River estuary, British Columbia, Canada. Replicate batches of marked smolts were transferred from a hatchery and released in 1983, 1984 and 1985 at four ecosystems, two that ensured estuarine experience (river, estuary) and two seawards of the estuary ...

Minimum 60 years of recording are needed to compute the sea level rate of rise in the Western South Pacific

open access: yesNonlinear Engineering, 2014
Sea levels generally oscillate with multi-decadal periodicities worldwide with up to the quasi-60 years detected in many tide gauges. Nevertheless, the most part of the literature on sea levels computes apparent rates of rise of sea levels much larger ...

Orchid genome evolution and trait innovation

open access: yesJournal of Integrative Plant Biology, EarlyView.
Orchids became one of the world's most diverse plant groups through genome‐driven innovations, unique relationships with fungi and pollinators, and remarkable adaptability. This review explains the origins of orchids and the evolution of their distinctive life forms, flowers, and ecological strategies and highlights promising directions for future ...

Natural and human-induced changes in summer climate over the East Asian monsoon region in the last half century: A review

open access: yesAdvances in Climate Change Research, 2015
In the last half century, a significant warming trend occurred in summer over eastern China in the East Asian monsoon region. However, there were no consistent trends with respect to the intensity of the East Asian summer monsoon (EASM) or the amount of ...

Variations in the Pacific Decadal Oscillation over the past millennium

open access: yesGeophysical Research Letters, 2005
Hydrologically sensitive tree‐ring chronologies from Pinus flexilis in California and Alberta were used to produce an AD 993–1996 reconstruction of the Pacific Decadal Oscillation (PDO) and to assess long‐term variability in the PDO's strength and periodicity.

The hunger artist and academic migration: On political depression and relational poverty

open access: yesThe Australian Journal of Anthropology, EarlyView.
Abstract This autoethnography presents fragments of an invisible life, an ordinary body navigating the terrain of ‘academic migration’ (2009–2025), from rejection as a PhD applicant to recognition as a high‐achieving graduate. Provoked by my recent pursuit of Fulbright Postdoctoral Award in the United States, I draw on Kafka's figure of the hunger ...

Climate change-induced amplification of extreme temperatures in large lakes

open access: yesCommunications Earth & Environment
Lake surface temperature extremes have shifted over recent decades, leading to significant ecological and economic impacts. Here, we employed a hydrodynamic-ice model, driven by climate data, to reconstruct over 80 years of lake surface temperature data ...

Simulated Response of the Pacific Decadal Oscillation to Climate Change

open access: yesJournal of Climate, 2016
Abstract The impact of climate change on the Pacific decadal oscillation (PDO) is studied using a fully coupled climate model. The model results show that the PDO has a similar spatial pattern in altered climates, but its amplitude and time scale of variability change in response to global warming or cooling.

Summer snow extent heralding of the winter North Atlantic Oscillation

open access: yes, 2003
[1] Winter climate over the North Atlantic and European sector is modulated by the North Atlantic Oscillation (NAO). We find that the summer extent of snow cover over northern North America and northern Eurasia is linked significantly (p < 0.01) to the ...
