Distribution models of polysphinctine parasitoid wasps (Hymenoptera: Ichneumonidae) reveal sampling bias and flag potentially overlooked host interactions

Insect Conservation and Diversity, EarlyView.
We quantified the geographical overlap between parasitoid wasps and their known host spiders. We could assess which parasitoid species have more limited information about their interactions and are subject to geographical survey bias. We generated sampling bias maps to assist other researchers in identifying where the main sampling gaps are.

Politicisation and Agricultural (Post‐)Exceptionalism in EU–Mercosur Association Agreement Negotiations

JCMS: Journal of Common Market Studies, EarlyView.
Abstract This article examines how the politicisation of EU trade policy – defined by heightened public salience, stakeholder polarisation and contestation – reshapes agricultural lobbying strategies, with a particular focus on the EU–Mercosur Association Agreement.

Morphological and molecular evidence reveals a new species of Characidium from the Ucayali‐Urubamba Piedmont, Peru, and novel molecular clades are proposed within the genus

Journal of Fish Biology, EarlyView.
Abstract A new species of Characidium is described from the Urubamba River basin, within the Ucayali‐Urubamba Piedmont ecoregion, Peru. The new species can be readily distinguished from all congeners, except Characidium cacah, Characidium chicoi, Characidium helmeri, Characidium mirim, Characidium nana, Characidium nupelia, Characidium sterbai ...

CARBON BALANCE AND VEGETATION DYNAMICS IN AN OLD‐GROWTH AMAZONIAN FOREST [PDF]

, 2004
Amazon forests could be globally significant sinks or sources for atmospheric carbon dioxide, but carbon balance of these forests remains poorly quantified.

Bath Treatments With Emamectin Benzoate Control Dactylogyrideans Infecting Colossoma macropomum Gills Without Altering Physiology of This Host Fish

Journal of Fish Diseases, EarlyView.
ABSTRACT Intensification of fish aquaculture worldwide has led to severe problems of diseases caused by parasitic dactylogyrideans. In this study, the anti‐dactylogyridean efficacy of treating Colossoma macropomum with baths of emamectin benzoate (EMB) was investigated for the first time, along with the effects of this treatment on the haematology and ...

Height-diameter allometry of tropical forest trees [PDF]

, 2011
Tropical tree height-diameter (H:D) relationships may vary by forest type and region making large-scale estimates of above-ground biomass subject to bias if they ignore these differences in stem allometry.

Agribusiness Supply Chains: From Green to Regenerative

Journal of Supply Chain Management, EarlyView.
ABSTRACT Supply chain management has traditionally prioritized maximizing profits, creating persistent tensions with social‐ecological systems (SES) despite sustainability efforts. Regeneration offers an alternative, ecocentric approach, yet it remains unclear how supply chains can operate within SES boundaries.
