Annual Temperature Variation, Not Number of Predators, Predicts Variation in Foraging Group Size Among Pigeons Worldwide

open access: yesBiology
Many life history traits show predictable patterns at broad biogeographical scales, yet much less is known about how behavioural traits vary across such gradients.

APHYLLOPHOROID FUNGI OF THE KIY ARCHIPELAGO. SPECIES COMPOSITION AND MYCOBIOTA CHARACTERISTICS

open access: yesTransactions of the Karelian Research Centre of the Russian Academy of Sciences, 2017
The analysis of the occurrence of aphyllophoroid fungi on islands of the Kiy Archipelago (Onezhskiy District, Arkhangelsk Region) is carried out for the first time. In total, 150 species of aphyllophoroid fungi were revealed.

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

open access: yesFEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Enhanced Ant Colony Algorithm Based on Islands for Mobile Robot Path Planning

open access: yesApplied Sciences
Path planning in complex environments presents a substantial research challenge for mobile robots. This study introduces an enhanced ant colony algorithm based on islands (EACI) for mobile robot path planning.

Nanodot to Nanowire: A strain-driven shape transition in self-organized endotaxial CoSi2 on Si (100)

open access: yes, 2012
We report a phenomenon of strain-driven shape transition in the growth of nanoscale self-organized endotaxial CoSi2 islands on Si (100) substrates. Small square shaped islands as small as 15\times15 nm2 have been observed.

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

An evaluation of the bryophyte flora of the Azores [PDF]

open access: yes, 2005
The diversity of bryophytes on the different islands of the Azores varies much between 104 and 324 species. Attempts have been made to explain the heterogenity of the bryoflora. There is a correlation between species numbers and age of the islands in the

Study of the island morphology at the early stages of Fe/Mo(110) MBE growth

open access: yes, 2008
We present theoretical study of morphology of Fe islands grown at Mo(110) surface in sub-monolayer MBE mode. We utilize atomistic SOS model with bond counting, and interactions of Fe adatom up to third nearest neighbors.

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

open access: yesMolecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

Landscape level assessment of the relationship of hydrologic conditions to tree island in water conservation Area 3 [PDF]

open access: yes, 1999
Water Conservation Area 3 is the largest of the water conservation areas covering approximately 2442 km2 (914 mi2). The habitats within this area of central Everglades marsh range from sloughs and wet prairies to sawgrass, brush, and tree islands ...
