Multiyear Drought Strengthens Positive and Negative Functional Diversity Effects on Tree Growth Response

open access: yesGlobal Change Biology, Volume 31, Issue 9, September 2025.
Mixed‐species forests may help trees better cope with increasing drought stress under climate change. We analyzed tree‐ring growth from nearly 1000 trees across 16 species in 9 experimental plantations across Europe to understand how tree diversity influences drought responses.

The American cocoa pod borer, Carmenta foraseminis, an emerging pest of cocoa: A review El barrenador americano de la mazorca de cacao, Carmenta foraseminis, una plaga emergente del cacao: una revisión

open access: yesAgricultural and Forest Entomology, Volume 27, Issue 3, Page 340-356, August 2025.
Abstract This review provides a synthesis of the available knowledge on Carmenta foraseminis, an emerging cocoa pest in northern South America. This moth was first described in 1995 in Panama, and its proliferation across the Amazon basin is currently threatening the production of cocoa in the region and may endanger the sector's sustainability. Hence,

Biermann Mechanism in Primordial Supernova Remnant and Seed Fields

open access: yes, 2006
We have studied the generation of magnetic fields by the Biermann mechanism in the pair-instability supernovae explosions of the first stars. The Biermann mechanism produces magnetic fields in the shocked region between the bubble and interstellar medium

INSECT LIFE AND LETTERS: THE STUDIES OF HANNS HEINZ EWERS AND OTTO AND ROSE HECHT

open access: yesGerman Life and Letters, Volume 78, Issue 3, Page 342-363, July 2025.
ABSTRACT This article argues that vast histories of war and displacement in the twentieth century are connected to the small and almost unnoticeable lives of insects, and that philology has much to gain from paying attention to insect worlds. We examine two case studies: the work of the German entomologist Otto Hecht and his wife, Rose Caro Hecht, and ...

Origin of the Ultrahigh-Energy Cosmic Rays and their Spectral Break

open access: yes, 2010
The energy spectrum, composition and arrival directions of ultrahigh energy cosmic rays (UHECRs) with energy above the cosmic ray ankle, measured by the Pierre Auger Observatory, are inconsistent if their origin is assumed to be extragalactic.

Response of Amblyseius swirskii to deltamethrin

open access: yesPest Management Science, Volume 81, Issue 6, Page 2800-2811, June 2025.
The analysis of toxicological and molecular data reveals target‐site as well as metabolic modifications associated with the resistance to deltamethrin in Amblyseius swirskii colonies. However, semi‐field assays show increased run‐off behavior after treatments with the same pesticide.

Overview on direct and indirect measurements of cosmic rays - Some thoughts on galactic cosmic rays and the knee

open access: yes, 2005
An overview is given on results from direct and indirect measurements of galactic cosmic rays. Their implications on the contemporary understanding of the origin of cosmic rays and the knee in their energy spectrum are discussed.Comment: Invited overview,

Rthoptera: Standardised insect bioacoustics in R

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 6, Page 1084-1094, June 2025.
Abstract Almost 100 years after the dawn of insect bioacoustics, freely available and robust analysis tools and protocols are still needed. We introduce Rthoptera, an open‐source R package designed for robust analysis of insect acoustic signals. It delivers accurate temporal and spectral measurements, along with intuitive visualisations, through a ...
