Associations between mycorrhizal dominance and woody species diversity shift with stand development and climate across subtropical and tropical forests in Taiwan

Ecography, EarlyView.
Mycorrhizal symbioses influence woody species diversity, but whether this association shifts with forest stand development remains underexplored. Using forest inventory data across subtropical and tropical forests in Taiwan, we found that woody species diversity was lower in ectomycorrhizal (EM)‐dominated than in arbuscular mycorrhizal (AM)‐dominated ...

Silencing the Circadian Clock Genes Cycle and Clock Disrupts Reproductive–Metabolic Homeostasis but Does Not Induce Reproductive Diapause in Arma chinensis

Insects
The circadian clock is a conserved timekeeping mechanism that enables organisms to anicipate and adapt to daily environmental cycles. While its role in photoperiodic diapause has been documented, its fundamental function in maintaining reproductive and ...

Meta-analysis reveals that seed-applied neonicotinoids and pyrethroids have similar negative effects on abundance of arthropod natural enemies [PDF]

PeerJ, 2016
Background Seed-applied neonicotinoids are widely used in agriculture, yet their effects on non-target species remain incompletely understood. One important group of non-target species is arthropod natural enemies (predators and parasitoids), which ...

Parasitoid insects unveil complex patterns of functional change across elevational bands

Ecography, EarlyView.
Climate change is rapidly reshaping how insects interact with their environment, potentially disrupting ecosystem complexity and essential functioning. While functional homogenisation has been extensively investigated for charismatic insect taxa, particularly pollinators, the response of parasitoids remains largely overlooked.

Beneficial insects are associated with botanically rich margins with trees on small farms

Scientific Reports, 2021
Beneficial insect communities on farms are influenced by site- and landscape-level factors, with pollinator and natural enemy populations often associated with semi-natural habitat remnants.

Study of a crop-pest-natural enemy model with Z-type control — An approach to pest management

, 2022
In this study, the Z-type control method is applied to an intraguild crop-pest-natural enemy model, assuming that the natural enemy can predate on both crop and pest populations.

Water Governance Under International Pressure: Policy Narratives, Food Security, Scarcity, and the Politics of Survival in Iran

Environmental Policy and Governance, EarlyView.
ABSTRACT Water governance is increasingly influenced by a paradox at the nexus of environmental scarcity and food security. Escalating water scarcity crises coincide with geopolitical disruptions that have exposed the fragility of global food supply chains, prompting states to expand domestic food production at the expense of water conservation ...

Keanekaragaman laba-laba dan potensinya sebagai musuh alami hama tanaman jambu mete

Jurnal Entomologi Indonesia, 2015
Sanurus sp., Acrocercops sp. and Helopeltis sp. are important pests of cashews in Nusa Tenggara Barat. Pesticide usage to control these pests has so far not been successful, and thus the usage of natural enemy as an alternative control methods should be ...

The effect of multiple natural enemies on a shared herbivore prey

Ecology and Evolution, 2019
Natural enemy diversity is thought to be important for effective suppression of herbivores in production systems. Studies investigating the importance of the diversity and composition of the natural enemy complex often use within‐year empirical studies ...
