A double-edged sword : Unrecognized cryptic diversity and taxonomic impediment in Eois (Lepidoptera, Geometridae)

The genus Eois Hübner (Geometridae: Larentiinae) comprises 254 valid species. Being a hyperdiverse genus, Eois potentially includes many undescribed cryptic species and embodies a problematic taxonomic scenario. The actual diversity of Eois is greatly underestimated and the Neotropical fauna needs to be well known since it figures as one of the most threatened terrestrial ecosystem. In the present

A novel hybrid dragonfly optimization algorithm for agricultural drought prediction

Palmer Drought Severity Index (PDSI) is known as a robust agricultural drought index since it considers the water balance conditions in the soil. It has been widely used as a reference index for monitoring agricultural drought. In this study, the PDSI time series were calculated for nine synoptic stations to monitor agricultural drought in semi-arid region located at Zagros mountains of Iran. Auto

Accounting for all territorial emissions and sinks is important for development of climate mitigation policies

The Paris agreement identifies the importance of the conservation, or better, increase of the land carbon sink. In this respect, the mitigation policies of many forest rich countries rely heavily on products from forests as well as on the land sink. Here we demonstrate that Sweden’s land sink, which is critical in order to achieve zero net emissions by 2045 and negative emissions thereafter, is re

Using ecological and field survey data to establish a national list of the wild bee pollinators of crops

The importance of wild bees for crop pollination is well established, but less is known about which species contribute to service delivery to inform agricultural management, monitoring and conservation. Using sites in Great Britain as a case study, we use a novel qualitative approach combining ecological information and field survey data to establish a national list of crop pollinating bees for fo

Socio-psychological factors, beyond knowledge, predict people's engagement in pollinator conservation

1. Nature conservation often depends on the behaviour of individuals, which can bedriven by socio-psychological factors such as a person's attitude, knowledge andidentity. Despite extensive ecological research about pollinator declines, there hasbeen almost no social research assessing the drivers of people's engagement inpollinator conservation.2. To address this gap, we used a large-scale, onlin

The influence of soil structure on microbial processes in microfluidic models

The way microbes behave in nature can vary widely depending on the spatial characteristics of the habitats they are located in. The spatial structure of the microbial environment can determine whether and to which extent processes such as organic matter degradation, and synergistic or antagonistic microbial processes occur. Investigating how the different spatial characteristics of microhabitats i

Phenological stage of tundra vegetation controls bidirectional exchange of BVOCs in a climate change experiment on a subarctic heath

Traditionally, biogenic volatile organic compound (BVOC) emissions are often considered a unidirectional flux, from the ecosystem to the atmosphere, but recent studies clearly show the potential for bidirectional exchange. Here we aimed to investigate how warming and leaf litter addition affect the bidirectional exchange (flux) of BVOCs in a long‐term field experiment in the Subarctic. We also ass

Covariation in population trends and demography reveals targets for conservation action

Wildlife conservation policies directed at common and widespread, but declining, species are difficult to design and implement effectively, as multiple environmental changes are likely to contribute to population declines. Conservation actions ultimately aim to influence demographic rates, but targeting actions towards feasible improvements in these is challenging in widespread species with ranges

Low cross-taxon congruence and weak stand-age effects on biodiversity in Swedish oak forests

Assessing cross-taxon congruence is vital for effective forest conservation, because different taxonomic groups may respond inconsistently to key habitat variables such as stand age. We examined six taxonomic groups—insects, arachnids, springtails, epiphytic lichens, bryophytes, and vascular plants—across 25 Swedish oak stands ranging from 19 to 165 years old to determine whether species richness

Reconstructing Reservoir Water Level-Area-Storage Volume Curve Using Multi-source Satellite Imagery and Intelligent Classification Algorithms

The water level-area-storage volume (Z-A-V) relationship serves as the cornerstone of reservoir operations, governing water allocation, flood mitigation, and power generation. Sedimentation-induced capacity alterations can progressively degrade Z-A-V accuracy, yet systematic curve updates remain inadequately implemented across developing nations. Traditional reconstruction approaches face inherent

Where to restore : Connectivity forest for spatial prioritization in forest landscape restoration

Forest loss, fragmentation, and transformation negatively impact forest biodiversity and ecosystem functionality worldwide. Improving landscape intactness and connectivity through restoration is critical. Determining where to restore remains, however, a challenge. As an approach for prioritizing restoration areas, we define connectivity forest (CFs) as forests outside recognized high conservation

Structural variation in the pangenome of wild and domesticated barley

Pangenomes are collections of annotated genome sequences of multiple individuals of a species1. The structural variants uncovered by these datasets are a major asset to genetic analysis in crop plants2. Here we report a pangenome of barley comprising long-read sequence assemblies of 76 wild and domesticated genomes and short-read sequence data of 1,315 genotypes. An expanded catalogue of sequence

Opposing effects of nitrogen versus phosphorus additions on mycorrhizal fungal abundance along an elevational gradient in tropical montane forests

Studies in temperate systems provide evidence that the abundance of arbuscular mycorrhizal fungal (AMF) depends on soil nutrient availability, which is mainly explained in the context of resource stoichiometry and differential plant biomass allocation. We applied this concept to an understudied ecosystem - tropical montane forest - analyzing root and AMF abundance along an elevational gradient wit

CEASA : Dominant spatial autocorrelation in dual-constraint calibration as the game-changer for hydrological modeling with high-uncertainty remotely sensed evaporation: Application to the Meichuan basin

Accurate evapotranspiration (ET) estimation is vital for hydrological modeling, yet remotely sensed ET (RS-ET) products are often limited by algorithmic uncertainties and sensor biases. To mitigate error propagation and better capture spatial patterns, this study introduces the Composite Efficiency of Absolute ET and Spatial Autocorrelation (CEASA) —a dual-constraint framework that integrates abso

Leveraging multi-source satellite imagery for improving daily reservoir water storage and inflow estimation in a catchment hydrological model

Accurate reservoir dynamics, particularly water storage and inflow, are crucial for release decisions and operation rule assessments. However, the lack of sufficient monitoring data has hindered the accurate representation of reservoir behavior in hydrological models. While the increasing availability of satellite imagery provides unprecedented opportunities for dynamic reservoir monitoring, its p

Seasonal divergence in the sensitivity of carbon and water fluxes to climate variability in terrestrial ecosystems

Understanding vegetation sensitivity to hydroclimate factors, especially how carbon and water cycles respond to climate change, is crucial for assessing ecosystem vulnerability. However, the seasonal sensitivity of carbon and water fluxes to temperature, radiation, soil water content, and vapor pressure deficit across diverse biomes and climates remains unclear. Here, we use 196 eddy covariance ob

Diversity modulates above-ground productivity in response to disturbances : The case of Iberian forests

Disturbances play a key role in forest dynamics globally, with various effects on productivity. Tree diversity is expected to attenuate the negative impact of disturbance on forest productivity, but its overall effect has been little explored and might depend on the functional composition. Here, we analysed whether forest productivity responses to disturbances were modulated by structural and func
