Background/aim: Regulatory T cells (Tregs) play a crucial role in inflammatory responses by regulating the activity of various immune cells. M2 macrophages induced by IL-10 and TGF-β exhibit anti-inflammatory functions and induce Treg differentiation. Although the beneficial effects of 3-bromo-4,5-dihydroxybenzaldehyde (BDB) on various diseases have been widely reported, the mechanisms, through which it alleviates allergic contact dermatitis (ACD) via Tregs and macrophages, are not well understood.

Soybean mitogen-activated protein kinase GmMPK6 enhances drought tolerance.

Biochem Biophys Res Commun

December 2024

Interdisciplinary Graduate Program in Advanced Convergence Technology and Science, Jeju National University, 102 Jejudaehak-ro, Jeju, 63243, Republic of Korea. Electronic address:

Soybeans are a critical crop that provides both protein and oil. In response to environmental stresses, mitogen-activated protein kinases (MPKs) play a key role in transmitting stress signals to the nucleus to initiate stress-responsive actions. Drought stress reduces plant development and productivity but the specific MPK responsible for drought stress responses has not been previously identified.

This study investigated the speciation and aqueous dissolution of macronutrients in fire ash from diverse ecosystems and speciation of ash and smoke from laboratory burning, exploring the variations and their causes. The speciation of phosphorus (P), calcium (Ca), and potassium (K) in fire ash from five globally distributed ecosystems was characterized by using X-ray absorption spectroscopy and sequential fractionation. Aqueous dissolution of the macronutrients was measured by batch experiments at acidic and alkaline pHs.

Worldwide comparison of carbon stocks and fluxes between native and non-native forests.

Biol Rev Camb Philos Soc

December 2024

Departamento de Ciencias de la Vida, Universidad de Alcalá, Facultad de Ciencias, Área de Ecología, Ctra. Madrid-Barcelona, km.33, 600, 28805, Alcalá de Henares, Madrid, Spain.

Climate change is one of the main challenges that human societies are currently facing. Given that forests represent major natural carbon sinks in terrestrial ecosystems, administrations worldwide are launching broad-scale programs to promote forests, including stands of non-native trees. Yet, non-native trees may have profound impacts on the functions and services of forest ecosystems, including the carbon cycle, as they may differ widely from native trees in structural and functional characteristics.

The costs and benefits of a dynamic host microbiome.

Trends Ecol Evol

December 2024

Department of Ornithology, Max Planck Institute for Biological Intelligence, Eberhard Gwinner Straße, 82319 Seewiesen, Germany.

All species host a rich community of microbes. This microbiome is dynamic, and displays seasonal, daily, and even hourly changes, but also needs to be resilient to fulfill important roles for the host. In evolutionary ecology, the focus of microbiome dynamism has been on how it can facilitate host adaptation to novel environments.

Characterization of plastic ingestion in urban gull chicks and its implications for their use as pollution sentinels in coastal cities.

Mar Pollut Bull

December 2024

Institut de Ciències del Mar (ICM), CSIC, Barcelona, Spain; Department of Evolutionary Biology, Ecology and Environmental Sciences, and Biodiversity Research Institute (IRBio), Facultat de Biologia, Universitat de Barcelona, Barcelona, Spain.

The increase of plastic pollution represents a significant ecological threat, particularly in human-impacted environments. However, the effects of plastic ingestion by urban wildlife are less understood. This study investigates the presence of microplastic (MPs; plastic <5 mm in size) and macroplastics (MaPs, plastic >5 mm in size) in yellow-legged gull (Larus michahellis) chicks inhabiting the urban marine ecosystem of Barcelona (northeastern Spain).

Lipid metabolism may play a critical role in fueling seed germination, but the knowledge of lipid metabolism during germination is still ambiguous. Here, we hypothesize that gibberellic acid (GA) promotes germination by means of enhancing lipid mobilization in Chinese pistachio (Pistacia chinensis Bunge), a species belonging to Anacardiaceae with high oil content in its seeds. A multi-omics approach has been applied to measure lipid mobilization during seed germination, and to identify the key regulators involved in GA-mediated lipid metabolism.

Intrinsic and environmental drivers of pairwise cohesion in wild Canis social groups.

Ecology

December 2024

Wildlife Research and Monitoring Section, Ministry of Natural Resources and Forestry, Peterborough, Ontario, Canada.

Animals within social groups respond to costs and benefits of sociality by adjusting the proportion of time they spend in close proximity to other individuals in the group (cohesion). Variation in cohesion between individuals, in turn, shapes important group-level processes such as subgroup formation and fission-fusion dynamics. Although critical to animal sociality, a comprehensive understanding of the factors influencing cohesion remains a gap in our knowledge of cooperative behavior in animals.

Mountain Dragons of the genus Diploderma has experienced rapid taxonomic change in the recent years. The fast rate of taxonomic changes often leads to insufficient data for newly described species on their morphological variation, especially regarding sexual dimorphism, as well as the missing information on their natural history and conservation status. Limited time for taxonomic works may also result in misidentification of "new species".

Article Synopsis
  • Arid islands have unique wildlife adapted to harsh environments, but climate change poses significant risks to their biodiversity and sustainability.
  • A study spanning 20 years observed a drastic decline of 63%-70% in an endemic bird species' population due to extreme weather and decreased rainfall, with the population dropping to around 4,650 individuals in 2024.
  • Results indicate that these birds require a larger habitat area to sustain their population, emphasizing the impact of severe climate events on not just this species but also other native birds sharing similar habitats.

Livestock predation constitutes the primary source of conflict between humans and large carnivores. Moreover, human factors, such as attitudes and emotions, can affect people's tolerance towards carnivores, exacerbating the conflict. Such conflicts often lead to retaliatory killing of carnivores, which not only poses significant threats to species conservation but also to ecosystem functioning and services.

Saline shallow lakes in arid and semi-arid regions frequently undergo drying episodes, leading to significant variations in salinity and water availability. Research on the impacts of salinity and drought on the structure and function of biofilms in hypersaline shallow lakes is limited. This study aimed to understand the potential changes of biofilms in playa-lake sediments during the drying process.

Ecological theory predicts that plant reproductive phenology in the Mediterranean regions is shaped by evolutionary processes driven by strong seasonality in precipitation-evaporation patterns. Thus, it can be expected that seed germination phenology has adapted to maximise recruitment during the season of highest water availability. Cold-cued and slow germination (i.

The accident that occurred at the Chornobyl nuclear power plant (Ukraine, 1986) contaminated a large extension of territory after the deposition of radioactive material. It is still under debate whether the chronic exposure to the radiation levels currently present in the area has long-term effects on organisms, such as decreases in longevity. Here, we investigate whether current levels of radiation in Chornobyl negatively impact the age of the Eastern tree frog .

Given the vulnerability of large and medium-sized mammal communities to climate change and human disturbances, understanding the spatial-temporal dynamics of these communities is essential for effective conservation planning. However, in many biodiversity hotspots, precise biological community assessments are insufficient. From 2012 to 2022, we deployed 784 camera traps in eight nature reserves (including sub-reserves) and one State Forest Farm (SFF, less strictly protected than a reserve) to study the composition and distribution of large and medium-sized mammals in tropical Xishuangbanna.
