Winter‐active spiders (Clubiona) have a hyperactive antifreeze protein with a unique beta‐solenoid fold

open access: yesThe FEBS Journal, EarlyView.
Antifreeze proteins from winter‐active spiders were purified using their affinity for ice. After LC–MSMS characterization, corresponding transcripts were identified. The antifreeze protein folds as a β‐solenoid with a large flat ice‐binding site on one surface and can bind to ice crystals and prevent their growth at −4 °C.

Galleria mellonella (L.) (Pyralidae) und Spodoptera exigua (Hübner) (Noctuidae): Wirkungsunterschiede zwischen XenTari® (Bacillus thuringiensis aizawai), NeemAzal T/S® und ihren Kombinationen [PDF]

open access: yes, 2008
Both, G. mellonella and S. exigua, are most important pests in tropical countries. G. mellonella has five to six generations per year (Abid et al. 1997; Ali 1996), there, and feeding in bee combs they find, besides wax, residues of honey, insect skin and

Characterization and diversity of the market-gardening production systems and their interactions with urban and peri-urban environment in Southern-Benin, West Africa [PDF]

open access: yes, 2013
The market-gardening production plays an important role in contribution to food availability. However this activity is limited by constraints and also generates harmful effects on health and environment. Thus to ensure the sustainability of this activity

Elevation, rather than land use, causes important dietary shifts in the Mediterranean golden eagle

open access: yesJournal of Zoology, EarlyView.
In an ever‐changing landscape, golden eagles in the Iberian Peninsula demonstrate remarkable dietary adaptability. We monitored 50 distinct breeding events over 4 years using camera traps, collecting over 520 000 images. Elevation, rather than land use, emerged as the main driver of prey composition: lagomorphs and columbiforms dominated at lower ...

Seeing herbaria in a new light: leaf reflectance spectroscopy unlocks trait and classification modeling in plant biodiversity collections

open access: yesNew Phytologist, EarlyView.
Summary Reflectance spectroscopy is a rapid method for estimating traits and discriminating species. Spectral libraries from herbarium specimens represent an untapped resource for generating broad phenomic datasets across space, time, and taxa. We conducted a proof‐of‐concept study using trait data and spectra from herbarium specimens up to 179 yr old,

Plant-Based Insecticides for Controlling Drosophila suzukii: Opportunities and Challenges for Biorational Nanoproducts

open access: yesAgrochemicals
Drosophila suzukii (Diptera) is a polyphagous fly responsible for a huge loss in production of thin-skinned berries, usually controlled with low-selective synthetic pesticides, which can be toxic for biodiversity and human health.
