Porous Organic Polymers: From Molecular Design to Scalable Technologies

open access: yesSmall, Volume 22, Issue 46, 18 August 2026.
This review introduces porous organic polymers (POPs) for a wide range of applications, including energy storage, gas adsorption, catalysts, adsorbents, biomedical applications, sensors, and other exciting fields, and critically analyzes the synthesis and modification, and how structural topology influences the composites' architecture of POPs, along ...

Digging into dirt: Rewilding with threatened mammals shapes soil‐emerging insect assemblages

open access: yesJournal of Animal Ecology, Volume 95, Issue 7, Page 1207-1219, July 2026.
By comparing insect communities across treatments at two time points, we show that reintroduced digging mammals shape soil‐emerging insect assemblages. This provides empirical evidence that restoring ecosystem engineers may drive broader community‐level change in semi‐arid ecosystems. Abstract Digging mammals function as ecosystem engineers by altering

Pump less wearable microfluidic device for real time pH sweat monitoring [PDF]

open access: yes, 2009
This paper presents the fabrication and the performance of a novel, wearable, robust, flexible and disposable microfluidic device which incorporates micro-Light Emitting Diodes (μ-LEDs) as a detection system, for monitoring in real time mode the pH of ...

Insecticides alter wild and managed pollination dynamics on oil crop yield

open access: yesJournal of Applied Ecology, Volume 63, Issue 7, July 2026.
Our results show that combining honey bee hives with insecticide use does not automatically enhance crop yield. Pollination outcomes are strongly scale‐ and context‐dependent, with wild pollinators providing disproportionately important services. Agricultural management should therefore prioritize integrated strategies that reduce pesticide pressure ...

Getting more than a fair share: nutrition of worker larvae related to social parasitism in the Cape honey bee Apis mellifera capensis [PDF]

open access: yes, 2002
Besides activation of ovaries and thelytokous reproduction of Cape workers, larval nutrition is an important aspect in parasitism of the African honey bee.

A Master Gardener Survey: Promoting Pollinator-friendly Plants Through Education and Outreach

open access: yesHortTechnology, 2020
As land-use patterns change over time, some pollinating insects continue to decline both in abundance and diversity. This is due, in part, to reductions in floral resources that provide sufficient nectar and pollen.

Tropical Bee Assemblage Diversity Decreases With Elevation While Body Size Increases

open access: yesBiotropica, Volume 58, Issue 4, July 2026.
Photos of bee specimens collected in the Colombian Andes across a nearly 3000 m elevational cline. They are arranged to illustrate both the decline in richness with elevation and the increase in community average body size with elevation. ABSTRACT Elevation gradients are powerful drivers of changes in species composition, richness, and functional ...

Deep learning for identifying bee species from images of wings and pinned specimens.

open access: yesPLoS ONE
One of the most challenging aspects of bee ecology and conservation is species-level identification, which is costly, time consuming, and requires taxonomic expertise.
