<title>Abstract</title> Clonal plants, like <italic>Salvinia auriculata</italic>, are widespread and perform important ecosystem functions, influencing the structure composition of ecosystems in which they occur. Some cyanobacteria biological nitrogen fixation (BNF) can affect plant growth, as (N) is a limiting nutrient. Therefore, we carried out greenhouse experiment with inoculation cyanobacterial strain <italic>Desmonostoc</italic> (UFLA 12) to investigate whether heterocystous favour...
Silicon (Si) is a widely recognized element in plant defense, often enhancing resistance to herbivory by strengthening cell walls and deterring feeding external herbivores. However, its impact on internal, endophytic herbivores, such as gall-inducing insects, remains underexplored. This study investigates the role of silicon Bauhinia brevipes, focusing effects insects. We hypothesize that while strengthens tissues reduces it may have limited effect internal feeders, Our results indicate...
Intra-individual variation in floral traits is linked to plant fitness, playing a central role sexual selection. This can arise from architectural constraints, such as flower position on the inflorescence axis, and environmental factors. In relation influences traits, most common causes of are presence pollinators, resource acquisition strategies availability local pools. We investigated how clonal integration depletion through defoliation affect trait stability Eichhornia crassipes, testing...
Climate change, particularly extreme rainfall, imposes stress on plants, which can be assessed using fluctuating asymmetry (FA) in leaves and key leaf traits. FA, is defined as random deviations symmetrical structures, a known bioindicator of environmental stress. Additionally, area (LA) specific (SLA) provide insights into plant responses to stressors. Mangrove plants have several mechanisms cope with constant flooding rainy periods. However, under rainfall conditions, their adaptive...
Megaloptera comprises approximately 400 species, of which 25 are recorded in Brazil and belong to Corydalidae Sialidae. Here, we provide new occurrence records for Corydalus diasi Navás, 1915 (Megaloptera: Corydalidae) Serra de Itabaiana National Park, Sergipe, where two females five males were collected using light traps from June 2022 May 2023. Specimens identified morphological analysis. We illustrations that will aid the elucidation species can be used understand its variation....
Despite the crucial role of domestic dogs as reservoirs for zoonosis and some most threatening diseases wild carnivores such distemper parvovirosis, little is known about epidemiological features risk factors involved in pathogen exposure that live human/wildlife interfaces actually contacts wildlife. Through a cross-sectional serological approach questionnaire survey, we assessed prevalence along with individual environment-associated four important viral rural living households around six...
Abstract Unplanned urban development has consequences for natural ecosystems, resulting in habitat fragmentation and loss. Arthropod responses to urbanisation are well documented the Global North, but no clear found South. We assessed beta diversity, composition, richness abundance of arthropods Turnera subulata an gradient. Urbanisation affected arthropod communities' more urbanised areas showed lower insect abundance. taxa did not respond homogeneously urbanisation. Turnover best explained...
Canine visceral leishmaniasis is an important zoonosis in Brazil. However, infection patterns are unknown some scenarios such as rural settlements around Atlantic Forest fragments. Additionally, controversy remains over risk factors, and most identified of dogs have been found urban areas. We conducted a cross-sectional epidemiological survey to assess the prevalence through three different serological tests, interviews with owners features households five remnants southeastern used...
Fire occurrences are a common perturbation in Cerrado ecosystems, and may differently impact the local biodiversity. Arthropods one of taxa affected by fires, among them, ants known as good bioindicators. We aimed to evaluate effect anthropic fires on epigaeic hypogaeic ant communities (species richness composition) areas with different post-fire event recovery periods. conducted study four during two weeks 2012 dry season: unburned three at times (one month, years). sampled pitfall traps...
Abstract Herbivory is ubiquitous. Despite being a potential driver of plant distribution and performance, herbivory remains largely undocumented. Some early attempts have been made to review, globally, how much leaf area removed through insect feeding. Kozlov et al., in one the most comprehensive reviews regarding global patterns herbivory, compiled published studies foliar removal sampled data on levels using standardized protocol. However, review by only 15 sampling sites, comprising 33...
Variations in plant genotypes and phenotypes are expressed ways that lead to the development of defensive abilities against herbivory. Induced defenses mechanisms affect herbivore insect preferences performance. We evaluated performance resistant susceptible Bauhinia brevipes (Fabaceae) attacks by gall-inducing Schizomyia macrocapillata (Diptera). hypothesized there is a positive relationship between resistance S. host because can have high adaptive value. architecture, nutritional leaf...
Natural selection favors the allocation of finite resources to different functions maximizing fitness. In this sense, some may decrease whereas others increase when are limited in a process called trade-off. However, great variety situations obscure trade-off detection clonal plants, such as ability generate offspring by growth that represents opportunities for resource uptake. The aim work was evaluate if integration and availability mediate biomass patterns E. crassipes through greenhouse...
As Unidades de Conservação possuem uma grande importância para a estabilidade do meio ambiente, havendo possibilidade uso sustentável, exemplo das Áreas Proteção Ambiental (APAs). Nessas áreas, vegetação remanescente configura um importante componente no monitoramento e avaliação da fragilidade ambiental. Assim, este estudo objetivou avaliar dinâmica espaço-temporal na APA Marituba Peixe (APA-MP), com fins diagnosticar ambiental remanescente. Foi utilizada imagem satélite RapidEye, o ano...
Density-dependent responses are an important component of the organism life-history, and resource allocation theory is a central concept to life-history theory. When varies due environmental changes, plant may change its morphology or physiology cope with new conditions, process known as phenotypic plasticity. Our study aimed evaluate how density affects Eichhornia crassipes patterns. A total 214 individuals in high low were collected. The effect was observed all traits examined including...
Body size is one of the most important factors regarding herbaceous perennial plants life-histories, and several fitness components these organisms are related to size. Clonal show distinct kinds reproduction can develop offspring by sexual or asexual ways. We aimed understand how body affects Comanthera nivea (Eriocaulaceae) verify clonal growth flower head production in this species. sampled 600 rosettes rupestrian grasslands performed linear regression analysis between number produced...
Aquatic plants are able to alter their morphology in response environmental condition variation, such as water level fluctuations. The aim of this study was evaluate the effect on Sagittaria montevidensis through measures vegetative structures formed drought and flood periods. We hypothesised that plant height biomass S. leaves will increase during periods, while diameter petioles, basal area dry sampled a total amount 270 individuals nine sediment banks per visit, totalling 1080 plants. In...
In this study, we hypothesized that the life history traits of Leiothrix spiralis and L. vivipara would be linked to soil factors rupestrian grasslands rosette size influenced by moisture. Soil analyses were performed from five populations four vivipara. each area, three replicates employed in 19 areas occurrence species, quantified attributes. The microhabitats these species show low favorability regarding factors. During dry season, their rosettes decreased diameter due loss its most...
