Responses to novelty in wild insular birds: comparing breeding populations in ecologically contrasting habitats by Samara Danel, Nancy Rebout, Léna Bureau, Timothée Zidat, Dora Biro, Francesco Bonadonna

“…In this study, we presented novel objects to two geographically isolated breeding populations of the black-faced sheathbill (Chionis minor), a sedentary land-based bird that frequents remote sub-Antarctic islands. In the first population (Chionis minor ssp. crozettensis), the “Crozet group” (Baie du Marin, Ile de la Possession, Crozet Islands), breeding pairs inhabit a variable habitat close to penguin (Aptenodytes patagonicus) colonies. …”

Using satellite imagery to assess the glacier retreat in King George Island, Antarctica by Ibeth Rojas-Macedo, Cinthya Bello, Wilson Suarez, Edwin Loarte, Fiorella Vega-Jacome, Maria G. Bustamante Rosell, Pedro M. Tapia

“…In this study, Landsat satellite images (1989–2020) were used to quantify glacier retreat in the ice cap of King George Island (KGI), located in the Antarctic Peninsula, and to evaluate the teleconnections of El Niño – Southern Oscillation - ENSO (ONI and SOI indices) with climatic variables (temperature and precipitation) in this region. …”

A novel conceptual model for Dansgaard–Oeschger event dynamics based on ice-core data by J. O. Melcher, S. Halkjær, P. Ditlevsen, P. L. Langen, G. Vettoretti, S. O. Rasmussen

“…Utilising a simplified two-equation framework derived from the Stommel model, our approach integrates an internal control parameter which acts as a feedback parameter on the Antarctic Bottom Water (AABW) formation. Through both analytical and numerical methods, we establish a suitable parameter domain within which the newly adjusted models can accurately replicate the palaeoclimatic records of DO events as described by summary statistics derived from ice-core data. …”

Climatic Background and Prediction of Boreal Winter PM2.5 Concentrations in Hubei Province, China by Yuanyue Huang, Zijun Tang, Zhengxuan Yuan, Qianqian Zhang

“…Near-surface easterlies and an anomalous anticyclonic circulation over Hubei contribute to reduced precipitation, thereby decreasing the dispersion of pollutants and leading to higher PM2.5 concentrations. (2) Significant correlations are observed between DJF-HBPMC and sea surface temperature (SST) anomalies in specific oceanic regions, as well as sea-ice concentration (SIC) anomalies near the Antarctic. For the atmospheric pattern anomalies over Hubei Province, the North Atlantic SST mode (NA) promotes the southward intrusion of northerlies, while the Northwest Pacific (NWP) and South Pacific (SPC) SST modes enhance wet deposition through increased precipitation, showing a negative correlation with DJF-HBPMC. …”

Enhancing microbial predator–prey detection with network and trait-based analyses by Cristina Martínez Rendón, Christina Braun, Maria Kappelsberger, Jens Boy, Angélica Casanova-Katny, Karin Glaser, Kenneth Dumack

“…For this, we investigated algae and their protistan predators in biocrusts of three distinct polar regions, i.e., Svalbard, the Antarctic Peninsula, and Continental Antarctica. Network analyses using FlashWeave indicated that 89, 138, and 51 correlations occurred between predatory protists and algae, respectively. …”
