Relationships between natural enemy diversity and biological control

, 2017
Natural enemy diversity generally strengthens biological control, but individual studies have found everything from positive to negative effects. We discuss the factors that promote these different outcomes.

Evidence for adaptive explanations of semelparity in animals

Biological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Molecular Identification of the Glutaredoxin 5 Gene That Plays Important Roles in Antioxidant Defense in Arma chinensis (Fallou)

Insects
Glutaredoxin (Grx) is a group of redox enzymes that control reactive oxygen species (ROS), traditionally defined as redox regulators. Recent research suggested that members of the Grx family may be involved in more biological processes than previously ...

Ecolabels as Instruments for Biodiversity Governance in Agri‐Food Systems: A Comparative Assessment of EU Certification Schemes

Business Strategy and the Environment, EarlyView.
ABSTRACT Biodiversity underpins ecosystem functioning and the provision of ecosystem services, yet it continues to decline due to intensive agriculture, pollution, habitat loss and climate change. Although ecolabels are increasingly used to communicate sustainability attributes and influence consumer choices, their role in addressing biodiversity ...

Towards a Biodiversity Positive Business Strategy: The MCRV (Monitoring, Conserving, Restoring, Valorizing) Framework

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Despite mounting regulatory pressure and growing scientific consensus on biodiversity loss, most corporate action remains reactive, fragmented, and strategically peripheral. Existing frameworks address what firms should report rather than how they can build the organizational capabilities required to act strategically.

Molecular identification of two thioredoxin genes and their function in antioxidant defense in Arma chinensis diapause

Frontiers in Physiology
Thioredoxin (Trx), an important part of thioredoxin systems, plays crucial role in maintaining the intracellular redox balance by scavenging reactive oxygen species (ROS).

Interaction Network and Niche Analysis of Natural Enemy Communities and their Host Bees (Hymenoptera: Apoidea) in fragments of Cerrado and Atlantic Forest

Sociobiology, 2018
Natural enemies are important components of solitary bee communities that nest in preexisting cavities because they act as a relevant mortality factor and can regulate population growth.
