Humic substances modulate bacterial communities and mitigate adverse effects of temperature stress in coral reef organisms.

J Appl Microbiol

January 2025

Centre for Environmental and Marine Studies (CESAM) and Department of Biology, University of Aveiro, Aveiro, Portugal.

Aims: In the present study, we tested if terrestrially-derived humic substances (HS) could mitigate the adverse effects of elevated temperature and UVB radiation on the bacterial communities of two hard corals (Montipora digitata and Montipora capricornis), one soft coral (Sarcophyton glaucum), sediment and water. We also examined the impact of temperature, UVB radiation and HS supplementation on coral photosynthetic activity, a proxy for coral bleaching.

Methods And Results: We performed a multifactorial experiment using a randomized-controlled microcosm setup.

Neotropical regions near the equator are recognized as speciation "hot spots" reflecting their abundant biodiversity. In western South America, the coasts of Panama, Colombia, Ecuador, the Galápagos Archipelago, and northern Peru form the Tropical Eastern Pacific biome. This area has the greatest heterogeneity of sympatric fiddler crab species of any portion of the planet.

The small-sized cervid Procervulus is considered as the most basal member of the Cervidae and one of the earliest ruminants bearing antler-like appendages. The Iberian Miocene record of this stem-cervid is extensively documented and largely overlaps with the Miocene Climatic Optimum (MCO), a transient period of global warming of particular interest when comparing present and near future conditions. Despite receiving a substantial amount of attention, histological studies on Procervulus are very scarce and only limited to postcranial remains of Procervulus praelucidus from Germany (MN3).

Toward a phylogenomic classification of magnoliids.

Am J Bot

January 2025

National Herbarium of NSW, Botanic Gardens of Sydney, Mount Annan, NSW, Australia.

Premise: Magnoliids are a strongly supported clade of angiosperms. Previous phylogenetic studies based primarily on analyses of a limited number of mostly plastid markers have led to the current classification of magnoliids into four orders and 18 families. However, uncertainty remains regarding the placement of several families.

Floodplain forests drive fruit-eating fish diversity at the Amazon Basin-scale.

Proc Natl Acad Sci U S A

January 2025

Centre de Recherche sur la Biodiversité et l'Environnement, Université de Toulouse, Institut de Recherche pour le Développement, Institut National Polytechnique de Toulouse, Université Toulouse 3 - Paul Sabatier, Toulouse F-31062, France.

Unlike most rivers globally, nearly all lowland Amazonian rivers have unregulated flow, supporting seasonally flooded floodplain forests. Floodplain forests harbor a unique tree species assemblage adapted to flooding and specialized fauna, including fruit-eating fish that migrate seasonally into floodplains, favoring expansive floodplain areas. Frugivorous fish are forest-dependent fauna critical to forest regeneration via seed dispersal and support commercial and artisanal fisheries.

Coastal eutrophication transforms shallow micro-benthic reef communities.

Sci Total Environ

January 2025

Naturalis Biodiversity Center, Darwinweg 2, 2333 CR Leiden, the Netherlands; IBED, University of Amsterdam, Sciencepark 904, 1098 XH Amsterdam, the Netherlands.

Article Synopsis
  • Coral reefs worldwide are suffering from coastal eutrophication, leading to decreased coral cover and increased harmful organisms like algae and invertebrates.
  • The study focuses on how micro-benthic communities, specifically foraminifera, diatoms, and bacteria, are influenced by turbidity associated with eutrophication in the Spermonde Archipelago, using environmental DNA analysis.
  • Findings indicate that shallower reef flat communities are much more affected by turbidity than deeper reef slope communities, with foraminifera and diatom ESVs serving as indicators of varying turbidity levels, thus highlighting the influence of local environmental conditions on these micro-benthic communities.

Freshwater ecosystems are highly biodiverse and important for livelihoods and economic development, but are under substantial stress. To date, comprehensive global assessments of extinction risk have not included any speciose groups primarily living in freshwaters. Consequently, data from predominantly terrestrial tetrapods are used to guide environmental policy and conservation prioritization, whereas recent proposals for target setting in freshwaters use abiotic factors.

Starch-rich plant foods 780,000 y ago: Evidence from Acheulian percussive stone tools.

Proc Natl Acad Sci U S A

January 2025

The Martin (Szusz) Department of Land of Israel Studies and Archaeology, Institute of Archaeology, Bar-Ilan University, Ramat Gan 5290002, Israel.

In contrast to animal foods, wild plants often require long, multistep processing techniques that involve significant cognitive skills and advanced toolkits to perform. These costs are thought to have hindered how hominins used these foods and delayed their adoption into our diets. Through the analysis of starch grains preserved on basalt anvils and percussors, we demonstrate that a wide variety of plants were processed by Middle Pleistocene hominins at the site of Gesher Benot Ya'aqov in Israel, at least 780,000 y ago.

Phylogenomics yields new systematic and taxonomical insights for Lissotriton newts, a genus with a strong legacy of introgressive hybridization.

Mol Phylogenet Evol

December 2024

Institute of Biology Leiden, Leiden University, P.O. Box 9505, 2300 RA Leiden, The Netherlands; Naturalis Biodiversity Center, P.O. Box 9517, 2300 RA Leiden, The Netherlands. Electronic address:

The ease with which genome-wide data can nowadays be collected allows complicated phylogenetic questions to be re-evaluated. Phylogenetic relationships among newts have often proven difficult to resolve due to the prevalence of incomplete lineage sorting and introgressive hybridization. For the newt genus Lissotriton, phylogenetic relationships are not settled and there is controversy surrounding the species status of several taxa.

Unravelling a Latent Pathobiome Across Coral Reef Biotopes.

Environ Microbiol

December 2024

Department of Biology and Centre for Environmental and Marine Studies (CESAM), University of Aveiro, Campus Universitário de Santiago, Aveiro, Portugal.

Previous studies on disease in coral reef organisms have neglected the natural distribution of potential pathogens and the genetic factors that underlie disease incidence. This study explores the intricate associations between hosts, microbial communities, putative pathogens, antibiotic resistance genes (ARGs) and virulence factors (VFs) across diverse coral reef biotopes. We observed a substantial compositional overlap of putative bacterial pathogens, VFs and ARGs across biotopes, consistent with the 'everything is everywhere, but the environment selects' hypothesis.

Running performance in Australopithecus afarensis.

Curr Biol

January 2025

School of Natural Sciences, University of Manchester, Michael Smith Building, Oxford Road, Manchester M13 9PT, UK.

The evolution of bipedal gait is a key adaptive feature in hominids, but the running abilities of early hominins have not been extensively studied. Here, we present physics simulations of Australopithecus afarensis that demonstrate this genus was mechanically capable of bipedal running but with absolute and relative (size-normalized) maximum speeds considerably inferior to modern humans. Simulations predicted running energetics for Australopithecus that are generally consistent with values for mammals and birds of similar body size, therefore suggesting relatively low cost of transport across a limited speed range.

The Urban Heat Island Effect (UHIE) is a globally consistent pressure on biological species living in cities. Adaptation to the UHIE may be necessary for urban wild flora to persist in cities, but experimental evidence is scarce. Here, we report evidence of adaptive evolution in a perennial plant species in response to the UHIE.

Article Synopsis
  • The study describes and compares the final stadium larvae of four species of south-east Asian Chlorocyphidae using genetic analysis and morphological features.
  • Identification was primarily based on matching mitochondrial COI markers with known adult specimens, though some species require considering known adult distributions for accurate determination.
  • The research highlights distinct morphological differences among the species, suggests the potential for localized identification keys, but concludes that a comprehensive generic-level key for the region may not be feasible.
