infinitylists: A Shiny application and R package for rapid generation of place‐based species checklists

Applications in Plant Sciences, Volume 13, Issue 3, May-June 2025.
Abstract Premise Biodiversity researchers often need to answer the question: “Which species of taxon X have been documented in (or near) spatial polygon Y?” Online databases with billions of occurrence records, including vouchered specimens and citizen science records, can provide the answer; however, quick spatial processing of huge biodiversity ...

Enigmatic new mammals from the late Eocene of Egypt [PDF]

, 2018
A new mammalian genus and species from the earliest late Eocene of Egypt is represented by a lower jaw fragment and two isolated lower molars. A rare combination of features and the fragmentary nature of the materials make their taxonomic assignment to ...

Numerous independent gains of daily torpor and hibernation across endotherms, linked with adaptation to diverse environments

Functional Ecology, Volume 39, Issue 3, Page 824-839, March 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Many endotherms from diverse taxonomic groups can respond to environmental changes through torpor, that is, by greatly reducing their energy expenditure for up to 24 hours (daily torpor) or longer (hibernation).

Adaptive evolution of the venom-targeted vWF protein in opossums that eat pitvipers. [PDF]

PLoS ONE, 2011
The rapid evolution of venom toxin genes is often explained as the result of a biochemical arms race between venomous animals and their prey. However, it is not clear that an arms race analogy is appropriate in this context because there is no published ...

Localization of brain stem motoneurons innervating the laryngeal muscles in the rufous horseshoe bat,rhinolophus rouxi [PDF]

, 1981
The motoneurons innervating the laryngeal muscles were localized in the rufous horseshoe bat,Rhinolophus rouxi, using the HRP method. HRP was applied to the cricothyroid muscle and to the cut end of the recurrent laryngeal nerve. Labeled motoneurons were

Down to earth: therian mammals became more terrestrial towards the end of the Cretaceous

Palaeontology, Volume 68, Issue 2, March/April 2025.
Abstract The end Cretaceous extinctions had a profound effect on mammalian diversity, especially on metatherians (marsupials and their extinct relatives). Could mammalian substrate preference have influenced differential survival patterns? The plant fossil record shows changing angiosperm leaf anatomy during the last ten million years of the Cretaceous

Latitudinal Variation in the Timing of Nest Predator Activity Is Habitat Specific

Global Ecology and Biogeography, Volume 34, Issue 1, January 2025.
ABSTRACT Aim The goal of this work was to investigate whether the community of avian nest predators shifts from nocturnal to diurnal with changes in latitude. This hypothesis was formulated 70 years ago, under the rationale that longer day length during the bird breeding season at high latitudes increases opportunities for visual predators.
