Field test of assumptions for using line transect distance sampling on rock ptarmigan

Wildlife Biology, EarlyView.
Reliable population estimates are essential for the management of harvested species. Line transect distance sampling using pointing dogs is an established survey method for willow ptarmigan and has also been proposed for the monitoring of rock ptarmigan.

Response of Remote Tropical West Pacific Islands to Climate Variability: A Multiproxy Record From T‐Lake, Palau, Spanning the Early Holocene to Present

Archaeometry, EarlyView.
ABSTRACT Lake sediments are natural archives of past environmental dynamics and how these systems have responded to past climate variability. Sediment geochemistry, governed by local geology and climate processes, is unique to each lake‐catchment and geochemical proxies must be validated for each study site.

ENSO Remote Forcing

, 2020
The El Niño‐Southern Oscillation (ENSO) is a coupled ocean‐atmosphere phenomenon of variability that is a leading source of seasonal climate prediction skill across the globe. The first ENSO prediction was made in the mid‐1970s, but it was another 10–15 years before operational centers, using simple, coupled climate models, began to make routine ENSO ...

Droughts and human impact in the ancient Uaymil region of the Maya lowlands inferred from a 2800‐year sedimentary archive at Lake Kaná, Mexico

Boreas, EarlyView.
The relationship between the climate and societal transformation in Maya lowlands has long been debated, particularly the role of drought in shaping the civilization trajectory during the Classic Period. A high‐resolution, multi‐proxy, geochemical record from Lake Kaná, located in the underexplored Uaymil region of the Yucatán Peninsula in Mexico ...

Temperature variability and its governing mechanisms within the Jailolo Strait, Indonesia

Kuwait Journal of Science
Long-term reanalysis data from the Bluelink ReANalysis 2020 (BRAN2020) are used to investigate temperature variability from 2010 to 2020 in the Jailolo Strait–Halmahera Sea, which is part of the Indonesian Throughflow (ITF) eastern route.

Multimodal ENSO Forecast

Abstract Predicting the onset of the El Niño Southern Oscillation (ENSO) in the current rapidly changing climate could help save thousands of lives annually. Since the variability of this phenomenon is increasing, its prediction is becoming more challenging in the post-2000 era.

Competitive interactions modify the direct effects of climate

Ecography, EarlyView.
As the climate is changing, species respond by changing their distributions and abundances. The effects of climate are not only direct, but also occur via changes in biotic interactions, such as competition. Yet, the role of competition in mediating the effects of climate is still largely unclear.

Intrinsic unpredictability of strong El Ni\~no events

, 2016
The El Ni\~no-Southern Oscillation (ENSO) is a mode of interannual variability in the coupled equatorial ocean/atmosphere Pacific. El Ni\~no describes a state in which sea surface temperatures in the eastern Pacific increase and upwelling of colder, deep

Environmental Drivers of Jumbo Squid During Fishery Collapse in the Gulf of California (2019–2024)

Fisheries Oceanography, EarlyView.
ABSTRACT The jumbo squid (Dosidicus gigas) is a cephalopod endemic to the eastern Pacific with significant ecological and economic importance. Its exploitation in the Gulf of California (GC) peaked in the 1990s, with catches exceeding 100,000 tons, but collapsed in 2009 and virtually disappeared by 2015, largely due to environmental changes and ...

Forecasting Climate Change Using a Multivariate Cointegrated System

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT A cointegrated vector equilibrium correction model of key climate variables including sea surface temperature, ocean heat content, Arctic sea‐ice extent and sea‐level change is built, driven by radiative forcing in which a stochastic trend arises due to anthropogenic emissions of greenhouse gases.
