Coastal ecosystems play a major role in global carbon cycling and storage, yet the contribution of calcifying macroalgal habitats, such as coralline algal beds (CABs; rhodolith and maerl beds), remains poorly understood. Because carbon cycling in CABs is governed by community productivity and calcification, which exert opposing effects on seawater carbonate chemistry, understanding the balance between these processes is essent...

The seasonality of forage production is one of the main challenges in semi-arid regions, where environmental conditions limit agricultural productivity. One promising option is the use of elephant grass ‘BRS Capiaçu’, together with deficit irrigation. This study evaluated the impact of different irrigation depths with brackish water (50%, 75%, 100% and 125% of the reference evapotranspiration – ET 0 ) on the productive, physio...

Adopting resilient practices is crucial to balancing food production and crop sustainability in semiarid regions. Therefore, adopting systems that provide greater stocks of water, carbon, and nutrients at the soil-plant interface is crucial. The objective of this study was to assess water, carbon, and nutrient stocks in the soil-plant systems of irrigated forage crops in the semiarid region of Brazil. The study was conducted i...

Urban environments exert selective pressures on the functional composition of plant communities. Green spaces associated with traffic are widespread in cities and could therefore support pollinator biodiversity. This emphasizes the need to characterize the diversity of pollination-related traits within plant communities occupying these habitats. Hence, we investigated how pollination-related functional traits are associated wi...

Interspecific alloparental care is a little-known behavior among Neotropical birds. Here, we describe the first case in South America involving hummingbirds (Trochilidae). In an urban area of São Paulo, Brazil, we observed an individual of Eupetomena macroura (Swallow-tailed Hummingbird) caring for the chicks of Chlorostilbon lucidus (Glittering-bellied Emerald). The observations were made during the months of August and Septe...

Multiform glioblastoma (GBM) is the most aggressive primary brain tumor, associated with high heterogeneity, treatment resistance, and poor survival. Temozolomide (TMZ), although the main chemotherapeutic agent used, shows limited efficacy due to low solubility, chemical instability, and acquired resistance. In this context, nanostructured systems can enhance their antitumor efficacy. This study aimed to develop and characteri...

In this study, we investigated the taxonomic identity and biotechnological potential of the actinobacterium Streptomyces sp. LaBMicrA B280, isolated from the rhizosphere of Inga edulis (Mart.). Our approach combined a phylogenomic approach, annotation of metabolic subsystems and biosynthetic gene clusters (BGCs), biological assays to assess antifungal, antimalarial, cytotoxic, and larvicidal activities, classical molecular net...

A spinal cord injury (SCI) is a neurological disorder that impairs motor and physiological functions and leads to a reduced quality of life and autonomy for the person affected. In this scenario, human-machine interfaces (HMIs) have emerged as an effective tool to leverage residual motor capabilities and benefit injured persons. This work aims to develop a closed-loop HMI system for lower-limb rehabilitation composed of an in-...

Forage production in semi‐arid regions of Brazil is limited by water deficit. This study aimed to identify the most adapted and efficient production systems and define their agricultural calendars for the semi‐arid region of Brazil. Twenty‐nine production arrangements that included different cropping conditions, plant density, plant cycles, water replenishment, use of soil cover and production arrangements based on the main cr...

This study aimed to evaluate the agronomic performance, crop evapotranspiration (ET c ), crop coefficients (K c , K cb and K e ) and yield response factor (K y ) of three forage cactus clones—Orelha de Elefante Mexicana (OEM), Miúda (MIU) and IPA Sertânia (IPA)—grown in a semiarid environment. Four experiments involving different irrigation strategies and the use of mulch were conducted between 2012 and 2020. The OEM clone pre...

The Portuguese man‐of‐war Physalia physalis is widely known for causing poisoning on human beings. Physalia physalis is mostly described as a predator of fish eggs and larvae. Here, we report for the first time that large fish can also be preyed by P. physalis . We present two hypotheses for the hunting strategies used, that we denominate fishing and scanning. In both strategies, P. physalis makes use of the tentacles to eithe...

The lack of water in semi‐arid areas presents challenges for agriculture, making it necessary to adopt strategies that optimise the use of this water resource. This study evaluated the effects of irrigation level on the growth, productivity, economic viability and water use indicators of different forage species in the semi‐arid region of Brazil. The study was carried out in two production cycles, with a bifactorial arrangemen...
