{"title":"Imperfect detection biases occupancy estimates in plants: A review and case study","authors":"Anna W. Wyngaarden, Megan L. DeMarche","doi":"10.1002/ecy.70525","DOIUrl":"https://doi.org/10.1002/ecy.70525","url":null,"abstract":"The distributions of rare species are often estimated from presence–absence data, but undetected occurrences (imperfect detection) can lead to consequential underestimates of occupancy. Despite its standard use in animal ecology, detection probability ( <jats:italic>p</jats:italic> ) is rarely incorporated into plant occupancy estimates. Plants with cryptic life stages or traits (e.g., seed banks, dormancy) may be especially prone to periods of unobservability, resulting in imperfect detection even when a species is present. We tested the hypothesis that cryptic traits lower detection by reviewing published estimates of <jats:italic>p</jats:italic> in plant systems. While taxa with cryptic traits, particularly annual plants with seed banks and deciduous geophytes, exhibited lower <jats:italic>p</jats:italic> , there was wide variation across genera and publications. We then conducted a case study of the rare, annual, aquatic plant, <jats:italic>Gratiola amphiantha</jats:italic> (snorkelwort), endemic to ephemerally rain‐filled granite rock outcrop pools, to estimate occupancy (Ψ), <jats:italic>p</jats:italic> , and their environmental drivers. We found that Ψ increased with deeper soils and larger pool areas. Snorkelwort exhibited a high but imperfect <jats:italic>p</jats:italic> (mean <jats:italic>p</jats:italic> = 0.87) that varied with competing vegetation cover and census date. Modeling Ψ across varying levels of survey effort showed that ignoring imperfect detection can underestimate total occupancy estimates by up to 43%; however, our empirical <jats:italic>p</jats:italic> estimates indicate a minimum of just two surveys can reach 95% detection for snorkelwort. Our findings demonstrate that imperfect detection is an important and underappreciated limitation in plant occupancy studies, even for species with high detection probability. For rare plants, explicitly incorporating taxon‐specific <jats:italic>p</jats:italic> estimates and marginally increasing survey effort can substantially improve the accuracy of occupancy models.","PeriodicalId":11484,"journal":{"name":"Ecology","volume":"8 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149021286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These large mammalian herbivores, including tapirs, camelids, cervids, and peccaries, have a significant impact on plant community structure, composition, and dynamics, especially in the Neotropics. Despite their ecological importance, a systematic understanding of ungulate dietary information has been lacking. The <i>NeoUngulatesDiet</i> database addresses this gap by compiling data from a wide range of sources, including peer-reviewed literature and gray literature such as master's dissertations, Ph.D. theses, and book chapters. <i>NeoUngulatesDiet</i> represents a comprehensive compilation of 200 studies conducted between 1976 and 2025. It includes data from 17 countries, 224 plant families, 1135 plant genera, and 2624 plant species consumed by 21 of 28 ungulate species across the Neotropical region. The database comprises a comprehensive repository of consumed plants, including their growth forms, the parts eaten, and associated animal feeding habits. It also provides key information for dietary studies, such as the methodology used, study locations, and the years in which data were collected. This compilation enables researchers to explore the dietary preferences and ecological roles of various ungulate species, which differ in digestive systems, body sizes, and feeding habits. The dataset highlights the need for conservation strategies, particularly for seven understudied Neotropical species for which no dietary information is currently available. Therefore, <i>NeoUngulatesDiet</i> serves as a valuable resource for conservation practitioners, supporting the design and implementation of targeted strategies to preserve biodiversity and ecosystem function in the Neotropical region.

LaManna","doi":"10.1002/ecy.70465","DOIUrl":"https://doi.org/10.1002/ecy.70465","url":null,"abstract":"<p>Understanding how environmental stress alters the strength of local interactions is key to explaining diversity in current and future plant communities. Along gradients of increasing environmental stress, traditional theory posits that plants experience stronger facilitative interactions and weaker antagonistic interactions. However, it remains unclear whether this pattern extends to the relative host-specificity of plant–microbe interactions along stress gradients. Understanding these dynamics is particularly important for plant interactions with pathogenic and mycorrhizal fungi, which can drive opposing density-dependent processes that shape plant community compositions. We posit that increases in abiotic environmental stress are associated with stronger associations between plants and mutualists as plants increasingly rely on facilitative resource partnerships to cope with abiotic environmental stressors. We tested this prediction along an abiotic stress gradient in the central Cascade Range of Oregon, USA, using overlapping datasets of large high-resolution forest inventory plots, soil chemistry, and amplicon sequencing. Consistent with our predictions, in low-elevation forest stands with benign abiotic conditions and abundant nutrients, tree composition was more correlated with pathogenic fungal composition than ectomycorrhizal fungal composition. However, in forests at high elevations with limited nutrients and harsher climates, tree community composition was more correlated with ectomycorrhizal fungal composition than pathogenic fungal composition. Additionally, we find that spatial aggregation of ectomycorrhizal fungi increases as abiotic stress increases with elevation and opposing patterns of pathogen and ectomycorrhizal relative abundance in different substrate layers. Together, our findings suggest that facilitative interactions in stressful environments extend to mutualist-plant interactions and such interactions play a key role in shaping forest composition along environmental stress gradients.</p>","PeriodicalId":11484,"journal":{"name":"Ecology","volume":"107 8","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148652480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Megaherbivores, in particular, radically alter vegetation. Yet, few studies have tried to predict the impacts of herbivores—or their extinction—on plant species composition and community structure. First principles suggest that preferred food plants should be most strongly suppressed by herbivores and released by herbivore loss, but this intuition may be misleading if plant responses are strongly contingent on functional traits and/or plant–plant interactions. We sought to predict the responses of plant species to size-selective herbivore-exclusion treatments in an African savanna, using data on herbivore diets and plant functional traits. Our analysis had three stages. First, we identified plant traits that predicted selectivity (use relative to availability) by the dominant herbivore species excluded by each experimental treatment: megaherbivores (elephant, giraffe; ≥1000 kg), mesoherbivores (buffalo, zebra, impala; 40–600 kg), and dik-dik (5 kg). Several plant traits predicted selectivity across multiple herbivore species, but each species' diet was best predicted by a distinctive suite of traits. Second, we tested whether herbivore selectivity alone predicted plant responses. Elephant selectivity uniquely predicted plant responses in exclosures relative to unfenced control plots (<i>R</i>² = 0.24–0.30); plant taxa strongly favored by elephants were ninefold more abundant inside exclosures. However, herbivore selectivity failed to predict differences in community structure between the different fenced exclusion treatments, suggesting that bottom-up effects of competition may intensify relative to consumptive effects as smaller herbivores are removed. Third, we show that including plant traits as covariates alongside elephant selectivity modestly improved predictability (<i>R</i>² = 0.27–0.50). Despite various sources of uncertainty and imprecision inherent in our approach, we show that elephant foraging decisions are a major determinant of plant community dynamics. Our findings indicate that models based on readily attainable data can substantially predict plant community responses to the loss or reintroduction of megafauna. Future work can refine our approach by incorporating additional plant traits associated with tolerance and competition, along with mechanistic measurements of herbivore preferences and biomass consumption, to predict even more accurately how large-herbivore population declines and extinctions will impact plant communities.</p>","PeriodicalId":11484,"journal":{"name":"Ecology","volume":"107 7","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ecy.70445","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148552522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
