From Purpose to Persistence: How Intentional Introductions by Humans Influence Ecological Niches of Non‐Native Plants

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 5, May 2026.
ABSTRACT Aim The intentional or unintentional transport of non‐native plants is key to overcoming geographic barriers. However, it remains unclear whether such introduction pathways associate with overcoming environmental barriers, which is key for successful invasion.

Trophic Niche Overlap Between the Invasive Crab Rhithropanopeus harrisii (Gould, 1841) and Native Crab Species in the Southwest Atlantic Coast

open access: yesMarine Ecology, Volume 47, Issue 3, May/June 2026.
ABSTRACT The introduction of exotic species is one of the main drivers of biodiversity loss in aquatic ecosystems. The Harris mud crab Rhithropanopeus harrisii, native to the Atlantic coast of North America, was recorded in the Patos Lagoon estuary (southern Brazil) in the 1980s, likely introduced via ballast water. However, the effects of this invader

Florpyrauxifen‐Benzyl Controls Cirsium arvense by Inhibiting Root Growth and Decreasing Root Bud Regeneration

open access: yesWeed Research, Volume 66, Issue 3, May/June 2026.
ABSTRACT Cirsium arvense L. (Canada thistle) is a perennial weed with an extensive root system and prolific vegetative propagation through adventitious root buds, making long‐term management challenging. Florpyrauxifen‐benzyl, a novel synthetic auxin herbicide, has shown potential for controlling broadleaf weeds, but its effects on C.

Power supply for carbon dioxide lasers [PDF]

open access: yes, 1973
An improved ac power supply for a CO2 laser which eliminates the need for ballast resistors to excite a stable discharge is disclosed. The method involves the connection of an inductance in front of the rectifier. This procedure provides a nondissapative

Physical and Ecological Forcings Drive the Particle Dynamics and Enhanced Carbon Export Efficiency in the Tropical Marginal Sea

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Marginal seas contribute disproportionately to the ocean carbon cycle but remain poorly constrained due to strong spatial and seasonal variability. Here, we combine newly collected in situ particle imagery with machine learning to reconstruct monthly, depth‐resolved climatologies of particle biovolume and size distribution in the South China ...

Radiographic evaluation of gastroliths in a group of 49 juvenile saltwater crocodiles (Crocodylus porosus) in the UK

open access: yesVeterinary Record, Volume 198, Issue 8, Page e343-e350, 18/25 April 2026.
Abstract Background Gastrolith ingestion is a known inherent behaviour in crocodiles. However, the interpretation of coelomic radiographs in crocodilians is challenging due to the limited informative literature in this field. Methods Dorsoventral coelomic radiographs of 49 juvenile saltwater crocodiles (Crocodylus porosus) were acquired twice, with an ...

Sub-collision hyperfine structure of nonlinear-optical resonance with field scanning

open access: yes, 2004
Some experimental evidences for methane are produced that the simple transition from frequency scanning of nonlinear-optical resonances to magnetic one may be accompanied with transition from sub-Doppler collisionally broadened structure to sub-collision

Upgrading of vibrating compactor of the railway track ballast of VPO-3000 machine [PDF]

open access: yesTransport Problems, 2012
In the course of work a new vibrating compactor with single-direction inertial forces according to the authors’ innovative license is applied. Examination of possible dependence on substantiation of the new vibrating device parameters is shown.
