Reduced adult stem cell fate specification led to eye reduction in cave planarians.

Nat Commun

January 2025

Departamento de Zoologia, Instituto de Biociências, Universidade de São Paulo, São Paulo, Brazil.

Eye loss occurs convergently in numerous animal phyla as an adaptation to dark environments. We investigate the cave planarian Girardia multidiverticulata (Gm), a representative species of the Spiralian clade, to study mechanisms of eye loss. We found that Gm, which was previously described as an eyeless species, retains rudimentary and functional eyes.

Article Synopsis
  • The subseafloor igneous basement contains a vast microbial habitat, but little is known about the life that exists there, especially in older sections over 65 million years old.
  • Recent research tested this by analyzing samples from the Louisville Seamount Chain, finding varied cell biomass indicating the presence of microbial life in rocks older than 65 million years.
  • The dominant bacterial genes found suggest active microbial processes related to nitrogen, sulfur, metal transformations, and hydrocarbon breakdown, highlighting a much broader range of subseafloor life than previously recognized.

Persistent but weak magnetic field at the Moon's midstage revealed by Chang'e-5 basalt.

Sci Adv

January 2025

State Key Laboratory of Lithospheric and Environmental Coevolution, Institute of Geology and Geophysics, Chinese Academy of Sciences, Beijing 100029, China.

The evolution of the lunar magnetic field can reveal the Moon's interior structure, thermal history, and surface environment. The mid-to-late-stage evolution of the lunar magnetic field is poorly constrained, and thus, the existence of a long-lived lunar dynamo remains controversial. The Chang'e-5 mission returned the heretofore youngest mare basalts from Oceanus Procellarum uniquely positioned at midlatitude.

Vascular cambium is the continuation of meristem activity at the top of plants, which promotes lateral growth of plants. The vascular cambium evolved as an adaptation for secondary growth, initially in early seed plants, and became more refined in the evolution of gymnosperms and angiosperms. In angiosperms, it is crucial for plant growth and wood formation.

Environmental microbial reservoir influences the bacterial communities associated with Hydra oligactis.

Sci Rep

December 2024

MTA-DE "Momentum" Ecology, Evolution & Developmental Biology Research Group, Dept. of Evolutionary Zoology, University of Debrecen, Debrecen, Hungary.

The objective to study the influence of microbiome on host fitness is frequently constrained by spatial and temporal variability of microbial communities. In particular, the environment serves as a dynamic reservoir of microbes that provides potential colonizers for animal microbiomes. In this study, we analyzed the microbiome of Hydra oligactis and corresponding water samples from 15 Hungarian lakes to reveal the contribution of environmental microbiota on host microbiome.

We introduce a family of membrane-targeted azobenzenes (MTs) with a push-pull character as a new tool for cell stimulation. These molecules are water soluble and spontaneously partition in the cell membrane. Upon light irradiation, they isomerize from trans to cis, changing the local charge distribution and thus stimulating the cell response.

Unraveling the drivers of optimal stomatal behavior in global C plants: A carbon isotope perspective.

Sci Total Environ

January 2025

College of Life Sciences and Oceanography, Shenzhen University, Shenzhen 518060, China. Electronic address:

Understanding the drivers of stomatal behavior is critical for modeling terrestrial carbon cycle and water balance. The unified stomatal optimization (USO) model provides a mechanistic linkage between stomatal conductance (g) and photosynthesis (A), with its slope parameter (g) inversely related to intrinsic water use efficiency (iWUE), providing a key proxy to characterize the differences in iWUE and stomatal behavior. While many studies have identified multiple environmental factors influencing g, the potential role of evolutionary history in shaping g remains incompletely understood.

Department of Urban and Rural Planning, School of Landscape Architecture, Beijing Forestry University, Beijing, 100083, China. Electronic address:

Cropland changes are crucial aspects of land-use/land-cover changes (LUCC), which profoundly influence agricultural sustainability and terrestrial ecosystem health. In the context of dynamic shifts within the natural environment, coupled with the evolution of agricultural practices and the transformation of agrarian systems and policies, the trajectory of farmland alteration has exhibited significant divergence across various nations and regions. This article delves into the intriguing phenomenon of China's cropland migrating up to mountains and down to wetlands and analyses its spatiotemporal pattern evolution from 1990 to 2020.

Evolution takes multiple paths to evolvability when facing environmental change.

Proc Natl Acad Sci U S A

January 2025

Department of Ecology and Evolutionary Biology, University of Michigan, Ann Arbor, MI 48109.

Life at all scales is surprisingly effective at exploiting new opportunities, as demonstrated by the rapid emergence of antimicrobial resistance and novel pathogens. How populations acquire this level of evolvability and the various ways it aids survival are major open questions with direct implications for human health. Here, we use digital evolution to show that changing environments facilitate the simultaneous evolution of high mutation rates and a distribution of mutational effects skewed toward beneficial phenotypes.

The Northern Antarctic Peninsula (NAP) and the West Antarctic Ice Sheet (WAIS) are likely to respond rapidly to climate changes by increasing the collapse of peripheral ice shelves and the number of days above 0 °C. These facts make this region a representative hotspot of the global sea level rise and the location of one of the global climate tipping points (thresholds in the Earth system whose changes may become irreversible, if exceeded). Understanding the climate evolution of the NAP, based on past evidences, may help infer its future scenario.

Adaptive radiations are characterized by an increase in species and/or phenotypic diversity as organisms fill open ecological niches. Often, the putative adaptive radiation has been studied without explicit comparison to the patterns and rates of evolution of closely related clades, leaving open the question whether notable changes in evolutionary process indeed occurred at the origin of the group. Anolis lizards are an oft-used model for investigating the tempo and mode of adaptive radiations.

Biophysical effects of croplands on land surface temperature.

Nat Commun

December 2024

Department of Natural Resources and the Environment, University of Connecticut, Storrs, CT, USA.

Converting natural vegetation to croplands alters the local land surface energy budget. Here, we use two decades of satellite data and a physics-based framework to analyse the biophysical mechanisms by which croplands influence daily mean land surface temperature (LST). Globally, 60% of croplands exhibit an annual warming effect, while 40% have a cooling effect compared to their surrounding natural ecosystems.

Strontium isotope (Sr/Sr) analysis with reference to strontium isotope landscapes (Sr isoscapes) allows reconstructing mobility and migration in archaeology, ecology, and forensics. However, despite the vast potential of research involving Sr/Sr analysis particularly in Africa, Sr isoscapes remain unavailable for the largest parts of the continent. Here, we measure the Sr/Sr ratios in 778 environmental samples from 24 African countries and combine this data with published data to model a bioavailable Sr isoscape for sub-Saharan Africa using random forest regression.

Relations among territoriality, abundance and habitat suitability are fundamental to the ecology of many animal populations. Theory suggests two classes of possible responses to increasing abundance in territorial species: (1) the ideal free distribution (IFD), which predicts smaller territory sizes and decreased fitness as individuals adaptively pack into suitable habitats, and (2) the ideal despotic distribution (IDD), which predicts stable territory sizes and fitness in preferred habitats for dominant individuals and increased use of marginal habitats, reduced fitness and changes in territory sizes for subordinate individuals. We analysed the territory sizes and locations of seven migratory songbird species occupying a 10-ha plot in the Hubbard Brook Experimental Forest, New Hampshire, USA over a 52-year period.
