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 ...

Not everyone is shrinking: increases in body mass and wing length in a Sand Martin (Riparia riparia) population in northwestern Italy over two decades

Ibis, EarlyView.
In recent decades, vertebrates, particularly birds, have exhibited notable morphological changes in response to climate change. In birds, these temporal trends usually entail a decrease in body mass and an increase in wing length, sometimes interpreted as a compensatory strategy to maintain migration.

Joint effects of elevated copper and temperature in juvenile Tambaqui exposed in black and white waters of the Amazon

Journal of Fish Biology, EarlyView.
Abstract This study aimed to investigate how exposure to elevated water temperature and metal concentration jointly affect the physiology of Amazonian fish. Aboard a research vessel in the Amazon, we evaluated the effects of water temperature (river T°C at 31.5°C and a + 4°C increase to 35.5°C) and of 3‐h copper (Cu) exposure (up to 600 μg/L) in ...

Has the Euro Paid Off? A Study of the Trade‐Induced Welfare Effects of the EMU

Journal of Money, Credit and Banking, EarlyView.
Abstract This paper aims to provide policy‐relevant insights into the effect of the euro on trade. It uses a new data set of bilateral international and intranational manufacturing trade flows for 69 countries over the period 1986−2016. A general equilibrium gravity model is estimated to quantify the welfare effect of the euro and its impact on ...

From Theory to the Field and Back Again: Fieldwork‐Based Research on Social Differentiation in Agrarian Studies

Journal of Agrarian Change, EarlyView.
ABSTRACT Fieldwork is the cornerstone of empirical research in agrarian studies. Discussion about methodological options has, however, not kept up with the innovative conceptual developments taking place within the discipline. This is particularly evident in the study of social differentiation, a key concern in agrarian scholarship. Through a review of
