Reduced fertilization regimes could boost biocontrol service without reducing crop yield

Insect Science, EarlyView.
Fertilization level influences pest control effectiveness in tomato crops. High fertilization increases plant growth and aphid density but reduces the performance of the parasitoid Aphidius ervi. In contrast, the predator Adalia bipunctata maintains consistent aphid suppression regardless of fertilization regime.

Ozone‐driven degradation of sex pheromone in Plutella xylostella: Implications for reproductive communication and mating success

Insect Science, EarlyView.
In this study, we examined whether realistic ozone concentrations can interfere with sexual communication in the insect pest Plutella xylostella, the diamondback moth. Ozone exposure caused a degradation of pheromone components, leading to significant changes in blend composition and component ratios.

Decades of Enclosure Protection Exert Composite Effects on Grassland Grasshopper Communities

Integrative Zoology, EarlyView.
Decades of enclosure protection have altered grasshopper community structure, with species‐specific effects on population dynamics. For the low‐mobility grasshopper Chorthippus fallax, abundance did not differ strongly between exclosure‐protected and overgrazed areas, but its egg development duration was longer in exclosures. The two C.

The Dual‐Use Conundrum of the Lisbon Treaty Regarding Space Governance: Solutions Through International Legal Interpretation?

Global Policy, EarlyView.
ABSTRACT An inherent divide features within the Lisbon Treaty between civilian and military/security competences; something previously more obvious via the ‘pillar system's’ separations. This division follows the Member States (MS) (natural) protection of their military/defence autonomy; their core sovereign powers.

Sanctions, National Security, and Free Speech

Global Policy, EarlyView.
ABSTRACT A fundamental, but largely overlooked, aspect of the New Washington Consensus is the use of national security arguments to restrict speech and punish disfavored speakers. Although the United States has a longer history of using sanctions to restrict speech in the terrorism context, it has recently applied sanctions to restrict political speech,
