Shifting baselines increase the risk of misinterpreting biodiversity trends

open access: yesEcography, Volume 2026, Issue 4, April 2026.
Ecological studies quantifying the impact of land‐use change on biodiversity may be sensitive to the choice of reference points – or baselines – particularly when sampling across human land‐use gradients and other space‐for‐time comparisons. Much depends on whether the chosen baseline has already undergone shifts in species composition because of ...

Normal transversality and uniform bounds [PDF]

open access: yes, 1999
For two ideals $I$ and $J$ of a noetherian ring, we characterize, in terms of the vanishing of Tor modules, when the associated graded ring of the sum $I+J$ is isomorphic to the tensor product of the associated graded ring of $I$ and the associated ...

Intercontinental comparisons of invasive spotted lanternfly egg mass densities and mortality patterns

open access: yesEcosphere, Volume 17, Issue 4, April 2026.
Abstract Spotted lanternfly, Lycorma delicatula (White) (Hemiptera: Fulgoridae), is an invasive species of planthopper native to China. Populations of this invasive insect have been detected in South Korea (2006), Japan (2009), and the United States (2014).

Human–Environment Interactions Shape Mosquito Seasonal Population Dynamics

open access: yesInsects
Mosquito species, including the Asian tiger mosquito, can transmit disease-causing pathogens such as dengue, Zika, and chikungunya, with their population dynamics influenced by a variety of factors including climate shifts, human activity, and local ...

Recasting the Elliott conjecture

open access: yes, 2006
Let A be a simple, unital, exact, and finite C*-algebra which absorbs the Jiang-Su algebra Z tensorially. We prove that the Cuntz semigroup of A admits a complete order embedding into an ordered semigroup obtained from the Elliott invariant in a ...

An Epigenetic Clock for Accurate Age Prediction in Atlantic Cod Populations for Improved Fisheries Management

open access: yesMolecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Fisheries management relies on accurate stock assessments, which in turn depend on precise age information. Recent molecular tools called ‘epigenetic clocks’ harness age‐related DNA methylation changes to build accurate and precise age‐prediction models.

The Cuntz semigroup, the Elliott conjecture, and dimension functions on C*-algebras

open access: yes, 2006
We prove that the Cuntz semigroup is recovered functorially from the Elliott invariant for a large class of C*-algebras. In particular, our results apply to the largest class of simple C*-algebras for which K-theoretic classification can be hoped for ...
