A new combination in Strophopappus (Asteraceae, Vernonieae, Lepidaploinae)

Nordic Journal of Botany, EarlyView.
Revisions of herbarium collections reveal a new combination in Strophopappus (Asteraceae, Vernonieae, Lepidaploinae). Strophopappus comprises nine species occurring in South America, eight of which are endemic to Brazil. Currently, Vernonia riedeliana is treated as a synonym of Strophopappus bicolor.

Occurrence of a Crocodile on Cocos Islands [PDF]

Nature, 1890
DURING a recent visit to Cocos Islands Mr. Ross showed me the skull of a crocodile of small size which had appeared about a year previously on the islands. It was first seen by a native Cocosian, who reported that he had seen something between a lizard and a log of wood in the sea. It then reappeared upon another island and destroyed a number of ducks,

Speciation with gene flow

PLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

Demographic Responses to Experimental Manipulation of an Enclosed Population of Invasive Brown Treesnakes (Boiga irregularis)

Population Ecology, Volume 68, Issue 3, July 2026.
We evaluated demographic responses of an enclosed population of brown treesnakes to two experimental perturbations: supplemental feeding followed by removal of the adult and sub‐adult cohort 2 years later. Our results indicate that adding food to the system increased the population growth rate by 50% within 6 months and that removing the adults and ...

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

Biological Reviews, Volume 101, Issue 3, Page 1091-1119, June 2026.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis
