Genetic composition of facultatively anadromous brown trout Salmo trutta L. in a freshwater‐lake system

open access: yesJournal of Fish Biology, EarlyView.
Abstract Brown trout (Salmo trutta) has adapted to a wide range of habitats and displays a variety of life‐history strategies. Being facultatively anadromous, populations without migration barriers to the sea consist of both resident and anadromous individuals in different proportions.

Modelling relationships between juvenile brown trout (Salmo trutta L.) density and landscape characteristics: Integration of electrofishing data and spatial data to assess population status

open access: yesJournal of Fish Biology, EarlyView.
Abstract Brown trout (Salmo trutta L.) are ecologically and economically important, but like many salmonids their populations are declining. Trout exhibit a high level of phenotypic plasticity, ranging from freshwater residency to anadromy. This complexity causes problems for assessment and constrains application of adult catch‐based assessment methods

The role of behavioural measures in successful fishway passage during seasonal brown trout (Salmo trutta) migration

open access: yesJournal of Fish Biology, EarlyView.
Abstract Successfully overcoming lateral barriers in rivers is crucial for longitudinal fish migration and is influenced mainly by fishway design, environmental variability and/or individual behavioural traits. Although behavioural traits are well studied in many contexts, their role in predicting fishway passage success in the wild remains poorly ...

Dependent Articulation in the Global Pesticide Complex: Argentina's Agrochemical Industry After the Generics Market Revolution

open access: yesJournal of Agrarian Change, EarlyView.
ABSTRACT Since the late 1990s, the pesticide industry has undergone a ‘generics revolution’ as the centre of production, and trade has shifted to the global South. China and India have become major producers, capturing Latin American markets from Northern multinationals. As a major pesticide user and a key node in global supply chains, Argentina offers

Remaking State Power Through a Paraquat Ban in Malaysia

open access: yesJournal of Agrarian Change, EarlyView.
ABSTRACT This paper examines the role of the state in its ability to enact environmental regulations. Specifically, this study investigates how Malaysian state actors changed, shifted and betrayed various, oftentimes competing interests to ban paraquat, an acutely toxic herbicide.
