A passage through India: the biotic ferry model supports the build-up of Indo-Australian biodiversity of an ancient soil arthropod clade

The paper reconstructs the biogeographic history of Scutigeromorpha, finding that in-situ diversification in the Peninsular Indian Plate and dispersal events explain the distribution of extant species, with a single dispersal event generating most of Australia's diversity.

Idiosyncrasies unveiled: examining the pace, patterns and predictors of biotic diversification in peninsular India

The paper examines diversification rates and drivers in Peninsular India's endemic lineages using molecular phylogenies and birth-death models, finding angiosperms diversified fastest and Miocene climate changes influenced patterns in some lineages.

libpspm: A feature-rich numerical package for solving physiologically structured population models

libpspm provides a numerical library for solving physiologically structured population models with multiple methods and flexible model definitions.

Incorporating photosynthetic acclimation improves stomatal optimisation models

The paper evaluates stomatal optimization models with and without photosynthetic acclimation, finding that including acclimation improves carbon assimilation predictions under drought.

Competition for light can drive adverse species-composition shifts in the Amazon Forest under elevated CO2

The paper uses a vegetation model to predict how elevated CO2 affects Amazonian forest composition and carbon dynamics under different soil conditions.

Range restricted old and young lineages show the southern Western Ghats to be both museum and cradle of diversity for woody plants

The paper examines the southern Western Ghats as both a museum and cradle of woody plant evolutionary diversity using phylogenetic and distribution analyses.

A bi-functional PARP-HDAC inhibitor with activity in Ewing sarcoma

This paper develops a dual PARP and HDAC inhibitor, kt-3283, showing enhanced cytotoxicity and efficacy in Ewing sarcoma models compared to single-agent inhibitors.

Newcastle disease burden in Nepal and efficacy of Tablet I-2 vaccine in commercial and backyard poultry production

The paper assesses Newcastle Disease burden in Nepal and evaluates the efficacy of the I-2 vaccine in poultry, finding high sero-prevalence and identifying new NDV strains, with the vaccine showing over 85% efficacy.

Genetic diversity varies with species traits and latitude in predatory soil arthropods (Myriapoda: Chilopoda)

The paper examines genetic diversity in centipedes, finding it varies with body size, latitude, maternal care, and geographic distance, while being influenced by evolutionary history and biogeography.

Optimal balancing of xylem efficiency and safety explains plant vulnerability to drought

The paper explains plant vulnerability to drought by showing that xylem efficiency and safety are optimally balanced, with gymnosperms having greater safety due to lower recovery capacity from conductivity loss.

Polytypy and systematics: diversification of Papilio swallowtail butterflies in the biogeographically complex Indo-Australian Region

This study re-examines the diversification of Papilio swallowtail butterflies using phylogenetic and biogeographic analyses to reveal higher species diversity and taxonomic restructuring.

Towards a unified theory of plant photosynthesis and hydraulics

This paper introduces a trait-based optimality theory that unifies stomatal responses and plant biochemical acclimation, validated with experimental data from 18 species.

Spatial patterns of phylogenetic diversity and endemism in the Western Ghats, India: a case study using ancient predatory arthropods

The paper analyzes phylogenetic diversity and endemism patterns in ancient arthropods across the Western Ghats using distribution data and phylogenetic analysis.

Improving prediction and assessment of global wildfires using neural networks

This paper uses neural networks to predict global wildfires, finding higher predictability with strong regional differences in fire-climate and fire-human relationships.

Large frugivores matter more on an island: insights from island-mainland comparison of plant-frugivore communities

The paper compares plant-frugivore communities on an island and mainland, finding the island community more asymmetric and nested, with figs and the Narcondam Hornbill playing central roles.

Bioinformatic and experimental evidence for suicidal and catalytic plant THI4s

The paper investigates plant THI4 enzymes, finding that some are suicidal while others are catalytic, with implications for thiamin synthesis and energy efficiency.

A multidimensional framework for measuring biotic novelty: How novel is a community?

The paper introduces the Biotic Novelty Index (BNI) to quantify ecological novelty by combining functional differences and temporal dynamics of species introductions, demonstrating its application in urbanization gradients and national scales.

Resilience trinity: safeguarding ecosystem services across three different time horizons and decision contexts

The paper introduces a conceptual framework called resilience trinity to manage ecosystem resilience across three decision contexts and time horizons.

Emergence of social inequality in a spatial-ecological public goods game

This study models how social inequality and overexploitation emerge in spatial-ecological public goods games under varying harvesting efficiency and dispersal costs.

Mobility can promote the evolution of cooperation via emergent self-assortment dynamics

This paper shows mobility can promote cooperation by enabling self-assortment of cooperators in dynamic populations without requiring information about others' traits or strategies.
