Too often, rodent management falls short of expectations because animals do not make the decisions we want. In this paper, we introduce the concept of \"behavior-based rodent management\" (BBRM) to promote a strategic focus on behavior in rodent management and help address this issue. BBRM is an extension of ecologically based rodent management (EBRM), which has been highly successful in improving rodent management outcomes by working with the ecological processes that drive rodent impacts. We suggest BBRM offers scope for significant further refinements in overcoming the challenges that rodent behavior poses to effective control of rodents and their impacts. Here, we first explain how rodents make decisions to interact with devices, shaped by risk-reward trade-offs and their motivational states. We then discuss three main factors that influence these decisions: the environmental context of the decision, temporal variation in decisions, and individual variation in responses. We explore how these factors not only challenge current practice but offer opportunities for novel approaches. We end by identifying priority areas for future research to address key unknowns about the nature of information and how rodents use it.</p>","PeriodicalId":13654,"journal":{"name":"Integrative zoology","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2026-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149109292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In urban environments, predation pressure is often altered, leading to shifts in antipredator strategies, and parasitism varies with changes in environmental quality and the introduction of novel hosts or vectors. Understanding how these processes are modified by urbanization is particularly urgent for amphibians, the most threatened group of vertebrates, as urban-driven changes may have profound consequences for fitness and population persistence. To explore these processes with an integrative perspective, we evaluated the effects of the anthropogenic footprint on the species Pelophylax perezi across six locations in central Spain with varying degrees of urbanization. We analyzed traits related to predator-prey and parasite-host interactions linked to survival and performance in altered habitats. Contrary to expectations, urban frogs had longer tibiofibulae and greater flight initiation distances, suggesting distinct selective pressures on antipredator responses in human-modified landscapes. Submersion time was unrelated to urbanization and body condition did not vary significantly, although it was greater in urban areas. Blood parasite diversity and abundance of Lankesterella, a genus of blood coccidian, increased with anthropogenic footprint. Moreover, urban frogs with worse body condition had higher loads of Lankesterella. Overall, our results show that urbanization modifies the morphology and interspecific interactions of this amphibian species, emphasizing the need to consider traits related to predator-prey and parasite-host interactions when assessing amphibian responses to urbanization and informing conservation strategies in increasingly urbanized landscapes.</p>","PeriodicalId":13654,"journal":{"name":"Integrative zoology","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2026-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149109302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To solve this problem, this study proposes MWAC, a model for accurate classification of wildlife species in infrared camera images by integrating image and text descriptions. First, we propose a wavelet KAN module (WDS-KAN) for multi-scale feature extraction of wildlife images, which enables the model to capture the subtle changes in animal images more accurately. Second, a label-correlated text extraction module (LC-BERT) is proposed to capture label co-occurrence patterns and hierarchical relationships in the dataset, which enhances the generalization ability of the model. Finally, a multi-strategy coati optimization algorithm (MSCOA) is proposed, which enhances our ability to globally search for the optimal solution, effectively avoids falling into local optima, and accelerates the model training speed. In order to verify the effectiveness of the model, we constructed a dataset containing 10 species of wild animals. The experimental results show that the MWAC model achieves 97.53% in accuracy, 97.33% in precision, 95.84% in recall, and 97.51% in F1, which are better than those of the existing models, indicating that the model is good for the rapid identification of wildlife and other aspects of good results and can be applied to large-scale wildlife monitoring and assessment.</p>","PeriodicalId":13654,"journal":{"name":"Integrative zoology","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149109270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to evaluate the effectiveness of RATs, including giving-up density (GUD) trays, chew cards, wax blocks, and active burrow counts in monitoring rodent abundance and predicting damage in rice fields in the Philippines. The effectiveness of these indices for monitoring rodent abundance and predicting damage were evaluated in rice fields over two consecutive cropping seasons. Relative abundance data were collected at early tillering (ET), maximum tillering (MT), and post-harvest stages of the rice crop. Tiller damage was assessed at maximum tillering (MT), booting (BT), and ripening (RP) stages. The optimum number of GUD stations for estimating rodent abundance and predicting damage was determined using different GUD arrays over three consecutive cropping seasons. Among the different RATs, GUDs measured during ET and MT showed the strongest associations with cumulative tiller damage, while burrow counts performed best at post-harvest. The use of eight-array grids of GUD stations per field resulted in the highest correlation with cumulative damage. To improve the efficiency of forecasting rodent damage in a current rice crop, we recommend the use of GUDs during the early stages of growth.

I use the IUCN Red List of Threatened Species which is conservative to explore how widespread the transition from rodent pest to endangered rodent is. Twenty-three percent of extant rodent species are of some conservation concern, and 64 species are threatened by persecution/control. The expansion of agropastoral production threatens 27% of rodent species, either alone or in conjunction with persecution. The transition from pest to endangered species can be rapid, as has been by the case for the now critically endangered European hamster (Cricetus cricetus). For some species, increase in the amplitude of outbreaks and hence incentives to control rodents are associated with the intensification of agricultural practices. Habitat fragmentation triggers metapopulation processes with thresholds for persistence depending on dispersal abilities as illustrated by the Eurasian water vole (Arvicola amphibius). Some extant species with low dispersal abilities are likely part of an extinction debt.

Predicted functional profiles of gut microbiota differed among species, primarily associated with environmental adaptation, antimicrobial resistance, immune regulation, and metabolic processes. The results indicate that rodent responses to rapid urbanization are different, in which urban exploiters (e.g., R. norvegicus) showed greater plasticity and resilience, while urban avoiders (e.g., N. confucianus) would suffer from more severe negative impacts.

Our previous study has reported that gallery microbiota could degrade D-pinitol to enhance the larval adaptation. However, the adaptive strategies of adults and larvae under differential D-pinitol stress are not yet fully understood. In this study, we explored the D-pinitol-degrading capacity and potential sources of gallery microbiota and compared the structures and functions of D-pinitol-degrading microbes in the guts between adults and larvae. We confirmed that gallery microbiota, rather than native pine endophytes, are responsible for D-pinitol degradation and the formation of a low-pinitol microhabitat, and we postulate that adult beetles are the major contributors to gallery microbiota. Additionally, adult guts harbored a higher abundance of Erwinia and Serratia compared with larval guts and exhibited a stronger D-pinitol-degrading capacity. Our results indicate that adults and larvae employ distinct strategies to overcome differential D‑pinitol stress from host pines. Specifically, adult beetles enrich more D‑pinitol‑degrading microbes in their guts, whereas larvae mainly rely on the external degradation of gallery microbiota.
