Global meta‐analysis reveals urban‐associated behavioural differences among wild populations

Journal of Animal Ecology, EarlyView.
Urbanization drives rapid phenotypic change, yet broad patterns of behavioural responses remain unclear. Using a global phylogenetic meta‐analysis, we show urban populations exhibit increased boldness, aggression, exploration and activity—especially in birds—highlighting consistent behavioural shifts and revealing major taxonomic gaps that limit our ...

Landscape configuration and soil properties shape ant‐mediated seed dispersal in tropical dry forest agricultural landscapes

Journal of Animal Ecology, EarlyView.
We show that ant‐mediated seed dispersal components respond differently to local soil conditions and landscape structure in Caatinga agricultural mosaics. Low‐intensity rainfed croplands maintained or enhanced seed removal compared to natural remnants, highlighting how small‐scale agriculture can sustain key ecological processes in human‐modified dry ...

Repurposing Agricultural Budgets With Multiple Objectives and Fiscal Constraints: A Multicriteria Decision‐Making Policy Tool Applied to Sub‐Saharan African Countries

Journal of Agricultural Economics, EarlyView.
ABSTRACT Repurposing agricultural public resources toward higher‐return incentives and investments can help transform agri‐food systems. This is important for low‐income countries, especially in sub‐Saharan Africa, where limited budgets restrict options for boosting agricultural spending.

Extinction Debt Paid Off: The Demise of the European Polecat (Mustela putorius) in NE Iberia

Integrative Zoology, EarlyView.
We studied a vanishing polecat population for a decade, until its ultimate demise, using camera trap and roadkill data, landscape descriptors and dietary and toxicological analyses.Polecat favoured farmland and avoided forests and water bodies occupied by the invasive American mink.

On the Reasons of Fish Escapes from Sea-cage Farms in the Aegean Sea

Turkish Journal of Agriculture: Food Science and Technology, 2019
A total of 48 randomly selected fish farms from the coasts of Izmir and Muğla, Aegean Sea were visited face-to-face interviewing with fish farmers and a total of 329 coastal fishermen, catches around the sea-cage fish farms between July 2015 and July 2017. We asked them the reasons for fish escapes from sea-cage fish farms. Answers were concerning with

Making Mining Licit: Gold, Commodification, and the Everyday Performance of Law in Colombia

American Anthropologist, EarlyView.
ABSTRACT Ethnographies of resource‐making have shown that the extraction of resource value from objects is premised on obviating the emplaced lifeworlds that surrounded objects before they traveled to consumer markets. Much of this literature looks at such supply‐chain disentanglement from the viewpoint of corporate and formal regulatory practices ...

Trace element signature on otoliths and scales for the detection of escaped seabass and gilthead seabream from mediterranean fish farms

, 2010
Significant differences in trace element signature of scales and otoliths have been found between wild and farmed Sparus aurata and Dicentrarchus /abrax in the southwestern Mediterranean. Furthermore, trace element composition in S.

Territorial and agonistic interactions between farmed and wild cod (Gadus morhua)

, 2010
Studies of contest competition between wild and farmed fish have mostly focused on fish with strongly territorial behaviour. Little is known about species with more plastic social behaviour, such as Atlantic cod (Gadus morhua L.), a species that can ...

Advancing conservation breeding programs for marine invertebrates

Conservation Biology, EarlyView.
Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.
