Computational Analysis of new Degree-based descriptors of oxide networks

Open Chemistry, 2019
Oxide networks have diverse applications in the polymer and pharmaceutical industries. Polynomials and degree-based topological indices have tendencies to correlate properties of molecular graphs.

Relational Intensification in Families During COVID‐19: A Comparative Study of Slovenia and Croatia

Family Relations, EarlyView.
ABSTRACT Objective This study examines how young people in Slovenia and Croatia perceived changes in family satisfaction, parent–child relationship quality, and family influence on important decisions before, during, and after the COVID‐19 pandemic. Background Pandemic restrictions redirected daily life toward family contexts and intensified family co ...

Acclimatization length and post‐release spatial cohesion in translocated Griffon Vultures (Gyps fulvus)

Ibis, EarlyView.
Translocations are often used in the conservation of large raptors, including Old World vultures. Different release methods are usually assessed by comparing the movement patterns and survival of released individuals. However, these approaches fail to capture the gregarious behaviour of many vulture species.

Comparing species accumulation within taxonomically well‐ and poorly resolved insect groups over 37 years

Insect Conservation and Diversity, EarlyView.
Here, we used a unique 37‐year (1969–2006) freshwater macroinvertebrate time‐series, collected over seven sites in central Germany, to study biodiversity patterns and species accumulation over time. Accumulation curves of Diptera diversity have not reached a plateau in 37 years of sampling.

On some topological indices of zero divisor graphs of direct product of three finite fields

Examples and Counterexamples
In this paper, we determine some degree-based topological indices, such as the Sombor index, the first and second Zagreb indices, the forgotten topological index, the Narumi–Katayama index, the first and second multiplicative Zagreb indices, the atom ...

Environmental and seasonal filtering of taxonomic, functional and phylogenetic diversity patterns of mountain butterflies in a prime butterfly area, Greece

Insect Conservation and Diversity, EarlyView.
Forest clearings support butterfly communities comparable to mountainous grasslands in alpha‐diversity and conservation value, yet remain compositionally distinct. Generalized linear models (GLMs) showed three key habitat predictors shaping multifaceted diversity and community composition: herb/grass height, flowerhead abundance and elevation.

Sharp bounds for the second Zagreb index and co-index under trees of given conditions

Mathematics Open
The second Zagreb index and co-index are two important graph invariants. They are defined as [Formula: see text] and [Formula: see text], respectively, where [Formula: see text] is the complement of G and [Formula: see text] is the degree of a vertex u ...

Dragonfly taxonomic and functional responses to urbanized streams in southeastern Europe, with management recommendations

Insect Conservation and Diversity, EarlyView.
Urbanization drives turnover in dragonfly species composition, traits, and habitat conservation value. Natural stream sections have a higher conservation value (higher DBI) due to presence of specialists. Properly managed urban streams can support diverse dragonfly assemblages.
