The world is undergoing massive atmospheric and ecological change, driving unprecedented challenges to human well-being. Olfaction a key sensory system through which these impacts occur. sense of smell influences quality satisfaction with life, emotion, emotion regulation, cognitive function, social interactions, dietary choices, stress, depressive symptoms. Exposures via the olfactory pathway can also lead (anti-)inflammatory outcomes. Increased understanding needed regarding ways in odorants generated by nature (i.e., natural environments) affect With perspectives from range health, social, sciences, we provide an overview this unique system, four consensus statements olfaction environment, conceptual framework that integrates into effects environments on We then discuss how contribute better accounting policy land-use decision-making and, turn, planetary health.

Plant induced responses to environmental stressors are increasingly studied in a behavioral ecology context. This is particularly true for plant herbivory that mediate direct and indirect defenses, tolerance. These seemingly adaptive alterations of defense phenotypes the context other conditions have led discussion such as intelligent behavior. Here we consider concept intelligence some its predictions chemical information transfer interaction with organisms. Within this framework, flow, perception, integration, storage considered tunable dials allow plants respond adaptively attacking herbivores while integrating past experiences cues predictive future conditions. The value costs acting on false important drivers evolution herbivory. We identify integrative priming mechanism allows mitigate potential associated information. mechanisms provide short- long-term memory facilitates integration without imposing significant costs. Finally, discuss ecological evolutionary prediction hypothesis.

Mixed cropping systems typically provide better natural pest control compared with monocultures, although the success varies depending on crop and cultivar combinations. Understanding trait interactions that confer associational resistance (AR) to companion plants is key optimizing these benefits. The Mesoamerican milpa system, known for its resistance, provides a model studying interactions. We tested two hypotheses investigate whether access extrafloral nectar (EFN) produced by Phaseolus vulgaris (common bean) can protect Zea mays (maize): (1) EFN enhances survival performance of parasitoid wasp, leading increased parasitism fall armyworm (FAW) caterpillars accompanying maize reduced herbivory, (2) bean detect herbivore-induced plant volatiles (HIPVs) respond increasing secretion. Controlled experiments demonstrated wasps from lived longer, had higher fecundity, parasitized more maize, thereby reducing herbivore damage. Additionally, caterpillar-damaged primed secretion in via HIPVs. Our findings reveal potentially important AR mechanism milpa, contributing reputed resistance. This understanding could inform design sustainable mixed enhance control.

Plants interact with each other via a multitude of processes among which belowground communication facilitated by specialized metabolites plays an important but overlooked role. Until now, the exact targets, modes action, and resulting phenotypes that these induce in neighboring plants have remained largely unknown. Moreover, positive interactions driven release root exudates are prevalent both natural field conditions controlled laboratory environments. In particular, intraspecific suggest genotypic recognition mechanism addition to non-self perception plant roots. This review concentrates on recent discoveries regarding how one another through signals intra- interspecific mixtures. Furthermore, we elaborate enhanced understanding can propel agroecology forward.

Plant-produced volatiles play a pivotal role as mediators in complex interactions between insects and plants. Despite the widespread recognition that these compounds serve cues for herbivorous to locate their preferred host plants, effects on insect mating behavior are less understood. Here, we show male oriental fruit flies (Bactrocera dorsalis) highly attracted plant volatile compound methyl eugenol (ME), which enhances attractiveness of leks females. To elucidate molecular underpinnings this phenomenon, identify olfactory receptor BdorOR94b1 responsible detecting ME. Genetic disruption leads complete abolition both physiological behavioral responses Additionally, confirm that, through digestion, convert ME (E)-coniferyl alcohol, This increased allows females select optimal mates, thereby enhancing reproductive success. The impairment detection significantly diminishes advantage within leks, males unable utilize effectively. Our findings unveil novel mechanism regulate economically important fly provide new insights into general ecology insect-plant interactions.

Summary Caterpillar feeding immediately triggers the release of volatile compounds stored in leaves cotton plants. Additionally, after 1 d herbivory, other newly synthesised volatiles. We investigated whether these volatiles affect chemical defences neighbouring plants and such temporal shifts emissions matter for signalling between Undamaged receiver were exposed to from infested with Spodoptera caterpillars. For plants, we measured changes defence‐related traits as emissions, secondary metabolites, phytohormones, gene expression, caterpillar preference. Then, compared effects emitted before 24 h damage on plant defences. Genes that upregulated following exposure damaged same those activated directly by herbivory a plant. Only damage, including produced volatiles, found increase phytohormone levels, upregulate defence genes, enhance resistance These results indicate induction is specific response de novo suggesting are honest signals herbivore attack. findings point an adaptive origin airborne

Greenbeards are selfish genetic elements that make their bearers behave either altruistically towards individuals bearing similar greenbeard copies or harmfully different copies. They were first proposed by W. D. Hamilton over 50 yr ago, to illustrate kin selection may operate at the level of single genes. Examples greenbeards have now been reported in a wide range taxa, but they remain undocumented plants. In this paper, we discuss theoretical likelihood existence We then question why concept has never applied plants and speculate on how hypothetical could affect plant-plant interactions. Finally, point research directions improve our knowledge
