The resource availability hypothesis revisited: a meta‐analysis

Functional Ecology, Год журнала: 2010, Номер 25(2), С. 389 - 398

Summary 1. Several theories have provided a framework for understanding variation in plant defence against herbivores. Among them, the apparency theory and resource availability hypothesis (RAH) aimed to explain patterns of investment selective pressures that led variety defensive strategies across species. Here we provide historical review both theories, present evidence shaped their development contrast predictions. 2. We results meta‐analysis utility RAH 25 years after it was proposed compare theory. performed 50 studies examined growth, defences herbivory relation latitude ontogeny. Specifically, tested four predictions follow RAH: (i) species adapted resource‐rich environments intrinsically faster growth rates than resource‐poor environments; (ii) fast‐growing shorter leaf lifetimes slow‐growing species; (iii) lower amounts constitutive (iv) support higher 3. Our confirm grow inherently more slowly, invest from productive habitats. data also showed rate among better explains differences apparency, suggesting evolution different is resource, rather herbivore driven. found application this appears robust ontogeny, as magnitude effect sizes most did not vary significantly between ecosystems or ontogenic stages. 4. conclude has served valid investigating its applicability quite general.

Explaining intraspecific diversity in plant secondary metabolites in an ecological context

New Phytologist, Год журнала: 2013, Номер 201(3), С. 733 - 750

Summary Plant secondary metabolites ( PSM s) are ubiquitous in plants and play many ecological roles. Each compound can vary presence and/or quantity, the composition of mixture chemicals vary, such that chemodiversity be partitioned within among individuals. ontogeny environmental genetic variation recognized as sources chemical variation, but recent advances understanding molecular basis may allow future deployment isogenic mutants to test specific adaptive function s.

Preferred reporting items for systematic reviews and meta‐analyses in ecology and evolutionary biology: a PRISMA extension

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Год журнала: 2021, Номер 96(5), С. 1695 - 1722

Опубликована: Май 7, 2021

Since the early 1990s, ecologists and evolutionary biologists have aggregated primary research using meta-analytic methods to understand ecological phenomena. Meta-analyses can resolve long-standing disputes, dispel spurious claims, generate new questions. At their worst, however, meta-analysis publications are wolves in sheep's clothing: subjective with biased conclusions, hidden under coats of objective authority. Conclusions be rendered unreliable by inappropriate statistical methods, problems used select research, or within itself. Because these risks, meta-analyses increasingly conducted as part systematic reviews, which use structured, transparent, reproducible collate summarise evidence. For readers determine whether conclusions from a review should trusted - able build upon authors need report what they did, why did it, found. Complete, reporting is measured 'reporting quality'. To assess perceptions standards quality reviews published ecology biology, we surveyed 208 researchers relevant experience (as authors, reviewers, editors), detailed evaluations 102 papers between 2010 2019.

Crop Domestication and Its Impact on Naturally Selected Trophic Interactions

Annual Review of Entomology, Год журнала: 2014, Номер 60(1), С. 35 - 58

Опубликована: Окт. 23, 2014

Crop domestication is the process of artificially selecting plants to increase their suitability human requirements: taste, yield, storage, and cultivation practices. There increasing evidence that crop can profoundly alter interactions among plants, herbivores, natural enemies. Overall, little known about how these are affected by in geographical ranges where crops originate, they sympatric with ancestral plant share associated arthropod community. In general, consistently has reduced chemical resistance against herbivorous insects, improving herbivore enemy performance on plants. More studies needed understand changes morphology resistance-related traits arising from may interact environmental variation affect species across multiple scales agroecosystems ecosystems.

Plant secondary metabolites: a key driver of litter decomposition and soil nutrient cycling

Journal of Ecology, Год журнала: 2016, Номер 104(6), С. 1527 - 1541

Опубликована: Июль 23, 2016

Summary A broad and diversified group of compounds, secondary metabolites, are known to govern species interactions in ecosystems. Recent studies have shown that metabolites can also play a major role ecosystem processes, such as plant succession or the process litter decomposition, by governing interplay between matter soil organisms. We reviewed ecological three main classes methodological challenges novel avenues for their study. highlight emerging general patterns impacts on decomposer communities decomposition argue consideration compounds key drivers functioning functioning. Synthesis . Gaining greater understanding plant–soil organisms relationships underlying mechanisms, including could improve our ability understand processes. outline some promising directions future research would stimulate aiming across range spatio‐temporal scales. Detailed mechanistic knowledge help us develop models nutrient cycling ecosystems predict global changes

Intraspecific trait variation in plants: a renewed focus on its role in ecological processes

Annals of Botany, Год журнала: 2021, Номер 127(4), С. 397 - 410

Опубликована: Янв. 27, 2021

Investigating the causes and consequences of intraspecific trait variation (ITV) in plants is not novel, as it has long been recognized that such shapes biotic abiotic interactions. While evolutionary population biology have extensively investigated ITV, only last 10 years interest ITV surged within community comparative ecology.
