Evaluating eDNA Metabarcoding Techniques for Pollinator Community Assessment in a Field and Controlled Experiment

open access: yesEnvironmental DNA, Volume 7, Issue 4, July–August 2025.
This study evaluates the use of environmental DNA (eDNA) metabarcoding on flowers to detect pollinator species and compares it with traditional visual sampling methods. Findings show that while eDNA complements conventional techniques in monitoring pollinators, it cannot fully replace them, highlighting the need for integrated approaches.

Insect Lipids as Novel Source for Future Applications: Chemical Composition and Industry Applications—A Comprehensive Review

open access: yesFood Science &Nutrition, Volume 13, Issue 7, July 2025.
Fat body (FB) acts as a major metabolic center important for the regulation of a variety of physiological processes such as embryogenesis, reproduction, flight, overwintering, protection, and communication. Lipid amounts and fatty acid (FA) composition vary with species, stage of life, and their diet.

From Columns to Networks: Search toward the Elusive Single Gyroid with π‐Shaped Polyphilic Liquid Crystalline Block Molecules

open access: yesSmall Science, Volume 5, Issue 7, July 2025.
A full spectrum of π‐shaped bolapolyphiles with self‐assembled phases ranging from honeycombs to segmented networks via a zeolite‐like structure is reported. The phase sequence suggests that self‐assembled single‐network phases require junction valence numbers of at least 4 to be thermodynamically stable. Polyphilic block molecules form a wide range of

Super‐Tough Silk: The Potential of Knots in Evolved Spiders

open access: yesAdvanced Functional Materials, Volume 35, Issue 15, April 10, 2025.
The toughness of spider silk can be further significantly enhanced if spiders evolved the –currently absent/undiscovered– ability to tie knots in their silk. The results on 393 spiders suggest toughness increments by one or two orders of magnitude and thus a new perspective on how knotting can serve as a key innovation in spider evolution and in ...

Insights Into Spatial Synchrony Enabled by Long‐Term Data

open access: yesEcology Letters, Volume 28, Issue 4, April 2025.
We review and synthesise some important recent advances in spatial synchrony, with a focus on how long‐term data have facilitated new understanding. Longer time series do not just facilitate better testing of existing ideas or more precise statistical results; more importantly, they also frequently make possible the expansion of conceptual paradigms ...

A hybrid approach for energy‐efficient routing in IoT using duty cycling and improved ant colony

open access: yesIET Communications, Volume 19, Issue 1, January/December 2025.
The proposed approach poses the empirical notion to manage the energy consumption of the IoT network by considering the key performance indicators (KPI) like energy consumption, average residual energy, mobility factor, distance, throughput, and network lifespan to accomplish the tangible outputs.The proposed approach is modelled using DFD's and ...

New York State Climate Impacts Assessment Chapter 05: Ecosystems

open access: yesAnnals of the New York Academy of Sciences, Volume 1542, Issue 1, Page 253-340, December 2024.
Abstract The people of New York have long benefited from the state's diversity of ecosystems, which range from coastal shorelines and wetlands to extensive forests and mountaintop alpine habitat, and from lakes and rivers to greenspaces in heavily populated urban areas.
