Understanding climate change impacts on biome and plant distributions in the Andes: Challenges and opportunities

Journal of Biogeography, Volume 49, Issue 8, Page 1420-1442, August 2022., 2022
Abstract Aim Climate change is expected to impact mountain biodiversity by shifting species ranges and the biomes they shape. The extent and regional variation in these impacts are still poorly understood, particularly in the highly biodiverse Andes. Regional syntheses of climate change impacts on vegetation are pivotal to identify and guide research ...

Guanaco colonisation of Tierra del Fuego Island from mainland Patagonia: Walked, swam, or by canoe?

Geo: Geography and Environment, Volume 9, Issue 2, July‐December 2022., 2022
A geographical and biological puzzle that has perplexed scientists since the late 1800s working in southern South America: why are there so few vertebrates on the island of Tierra del Fuego compared to the adjacent Patagonia mainland, including the absence of the ubiquitous Guanaco (Lama guanicoe), wild camelid of the south? An interdisciplinary search

THE ABUNDANCES OF THE ELEMENTS OF THE MAGELLANIC CLOUDS

Odessa Astronomical Publications, 2010
The results of the spectroscopic researches of classical Chepheids of the Magellanic Clouds (MC) are presented in this paper. 21 spec tra for the Large Magellanic Cloud (LMC) and 10 for the Small Magellanic Cloud (SMC) were investigated.

Taxonomy based on limited genomic markers may underestimate species diversity of rockhopper penguins and threaten their conservation

Diversity and Distributions, Volume 27, Issue 11, Page 2277-2296, November 2021., 2021
Abstract Aim Delimiting recently diverged species is challenging. During speciation, genetic differentiation may be distributed unevenly across the genome, as different genomic regions can be subject to different selective pressures and evolutionary histories.

Residual velocities of Small Magellanic Cloud star clusters [PDF]

Monthly Notices of the Royal Astronomical Society, 2021
ABSTRACT We analysed the largest Small Magellanic Cloud (SMC) cluster sample (32) with proper motions and radial velocity measurements, from which we obtained their space velocity components. By adopting as a reference, the recent best-fitting rotating disc of SMC star clusters as a function of the position angle, we computed their ...

Comparison of Rutherford's atomic model with the Standard Model of particle physics and other models

Journal of the Royal Society of New Zealand, Volume 51, Issue 3-4, Page 538-556, September ‐ December 2021., 2021
ABSTRACT Ernest Rutherford is known almost universally as the discoverer of the structure of the atom. He is less well known for his discovery of the proton. Even less well known is a set of hypotheses on the structure of matter that was proposed by Newton 300 years ago.

Low-excitation blobs in the Magellanic Clouds [PDF]

, 2006
Aims : We study an unknown, or very poorly known, interstellar HII component in the Magellanic Clouds. This is the first study ever devoted to this class of objects, which we call Low-excitation blobs (LEBs).
