The Birthrate of Magnetars

open access: yes, 2007
Magnetars, neutron stars with ultra strong magnetic fields ($B\sim 10^{14} - 10^{15}$G), manifest their exotic nature in the form of soft gamma-ray repeaters and anomalous X-ray pulsars. This study estimates the birthrate of magnetars to be $\sim$ 0.22

Dynamic Updating of Cognitive Maps via Traces of Experience in the Subiculum

open access: yesHippocampus, Volume 36, Issue 2, March 2026.
ABSTRACT In the classical view of hippocampal function, the subiculum is assigned the role of the output layer. In spatial paradigms, some subiculum neurons manifest as so‐called boundary vector cells (BVCs), firing in response to boundaries at specific allocentric directions and distances.

Not just ‘super‐predators': human behaviour shapes wildlife behavioural responses across avoidance, tolerance and attraction

open access: yesOikos, Volume 2026, Issue 3, March 2026.
Humans are thought to have a disproportionately negative impact on wildlife and are viewed by some as the ultimate ‘super predator'. This view implies that wild animals perceive humans primarily as predators. However, a growing body of evidence shows that wildlife can have remarkable tolerance for, or even attraction to, humans.

Landscape Composition and Proximity to Water Affect American Badger Occupancy in Shortgrass Prairies 景观组成和与水的距离影响矮草草原中美洲獾的占域率

open access: yesWildlife Letters, Volume 4, Issue 1, Page 23-31, March 2026.
American badgers, a medium‐sized carnivore occurring in much of North America, are important predators in prairie landscapes though our understanding of their habitat use requirements in these areas is unclear. We used a multi‐scale approach to understand American badger habitat use at both local and landscape scales.

Patterns and Determinants of Mortality in Grey Wolves (Canis lupus)

open access: yesMammal Review, Volume 56, Issue 1, March 2026.
This systematic review reveals the global patterns and drivers of grey wolf mortality, highlighting the high mortality risk associated with human coexistence for this cursorial carnivore, and reshaping previous knowledge to guide management and conservation strategies.

Vanishing of quasi-invariant generalized functions [PDF]

open access: yes, 2012
Determination of quasi-invariant generalized functions is important for a variety of problems in representation theory, notably character theory and restriction problems.

Understanding Why Grey Squirrels (Sciurus carolinensis) Bark Strip in British Woodlands: A Systematic Map

open access: yesMammal Review, Volume 56, Issue 1, March 2026.
Studies investigating the bark‐stripping behaviour of squirrel species that cause economic damage focus on developing methods to manage the behaviour. On the other hand, studies investigating the behaviour of species that do not cause economic damage focus on understanding the behavioural ecology of the species to meet conservation objectives.

The weak (1,1) boundedness of Fourier integral operators with complex phases

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 3, March 2026.
Abstract Let T$T$ be a Fourier integral operator of order −(n−1)/2$-(n-1)/2$ associated with a canonical relation locally parametrised by a real‐phase function. A fundamental result due to Seeger, Sogge and Stein proved in the 90's gives the boundedness of T$T$ from the Hardy space H1$H^1$ into L1$L^1$. Additionally, it was shown by T.
