Twenty-four plants were monitored for 22 months, with 10 of them affected by fire. We quantified and compared leaf number, production, and mortality, and evaluated their relationships with environmental factors (rainfall, temperature, and humidity), considering two groups: burned and unburned. Trunk height was measured and related to phenological events. Only one plant died post fire. Burned and unburned groups showed no significant differences in trunk height, leaf number, production, or mortality. Both groups exhibited discontinuous and irregular leaf production and mortality patterns. Both groups produced leaves immediately post fire, though with differences in peak timing. Burned plants displayed a rapid peak in leaf production (September), earlier than the peak in unburned plants (November). Only leaf mortality in unburned plants was positively correlated with rainfall and humidity. This study demonstrated a rapid recovery in leaf numbers following accidental fire for C. mexiae. The study revealed non-seasonal trends in the leaf production patterns of C. mexiae, with fire potentially inducing leaf mortality, reducing the sensitivity of this phenophase to environmental factors, and altering the timing of peak leaf production between the groups.</div>","PeriodicalId":794,"journal":{"name":"The Science of Nature","volume":"112 3","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144084989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study used high-throughput sequencing technology to explore the vertical distribution characteristics and influencing factors (depth, heavy metals, and nutrients) of bacterial communities in sediment core B18 from the Bohai Sea. Our results indicated that the dominant phyla were Proteobacteria, Desulfobacterota, Acidobacteriota, Chloroflexi, Bacteroidota, and Actinobacteriota, with Alphaproteobacteria, Gammaproteobacteria, Bacteroidia, Anaerolineae, Thermoanaerobaculia, and Desulfobulbia as the dominant classes. Depth exerted a pronounced influence on bacterial community diversities, with bacterial communities (excluding Proteobacteria, Bacteroidota, and Verrucomicrobiota) displaying a positive correlation with depth. Anaerobic bacteria like Desulfobacterota and Chloroflexi were more prevalent in the deeper sediment layers. In contrast, most bacterial communities exhibited a negative relationship with heavy metal concentrations. Notably, As, Pb, and Cd contents exhibited relatively high levels of pollution and had a considerably negative effect on bacterial diversity. Bacterial communities with adaptability to heavy metals (such as Proteobacteria, Bacteroidota, Verrucomicrobiota) demonstrated a competitive advantage in the Bohai Sea sediment bacterial community compositions. Meanwhile, bacterial communities related to nitrogen, phosphorus, and sulfur cycling (Proteobacteria, Bacteroidota, Verrucomicrobiota) were relatively abundant.

From both basic and applied research perspectives, it is important to investigate the mechanistic bases underpinning the insect-microbe symbiotic association. Here, we performed detailed electron and optical microscopic analyses of the early nymphal midguts to reveal the type of cellular structure and property that orchestrates the symbiont colonization in the restricted part of the midgut. We identified two peculiar structural features of the nymphal midgut that develop in a region-restricted manner: long and heterogenous cellular protrusions (microvilli) solely emerged in the midgut symbiotic region and highly developed circular muscle cell layers specifically observed in the junction of non-symbiotic and symbiotic regions of the midgut.

In spiders, parental investment is carried out mainly by females. Despite this, newly hatched eggs can still be targets of a series of natural enemies. In a remnant of Atlantic Forest in Brazil, females of the spider Eldar galadrielae sp. nov., family Anyphaenidae, build nests at the forest’s edge by folding plant leaves. However, information about the plants chosen for nest, the importance of maternal care by females in offspring survival, and predators are completely unknown.
