Beyond Species Diversity: Functional Approaches Reveal Consistent Fauna Community Responses to Exotic Grass Invasion in Arid Lands

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
To assess whether the impacts of exotic plant invasion can be generalised across taxa, we developed a conceptual framework predicting faunal responses to grass invasion in open, arid ecosystems and tested our predictions using data on birds, reptiles and ants from sites invaded by buffel grass (Cenchrus ciliaris) and paired uninvaded sites.

Depletion Estimation, Stock–Recruitment Relationships, and Interpretation of Biomass Reference Points

open access: yesFishes
Stock depletion level is an important concept in the assessment and management of exploited fish stocks because it is often used in conjunction with reference points to infer stock status.

Census and ear-notching of black rhinos (Diceros bicornis michaeli) in Tsavo East National Park, Kenya [PDF]

open access: yes, 2011
This paper updates the status of the black rhino population in Tsavo East National Park (NP). Data were acquired through aerial counts of the black rhino between 3 and 9 October 2010 using three fixed-wing husky aircrafts and a Bell 206L helicopter in an

DnaDot - fixing ecology and evolution’s blind spot, population size

open access: yesEcological Indicators
To understand and manage any ecosystem, one of the most critical indicators is census population size (‘Nc’) for each component species. This is why the International Union for Conservation of Nature (IUCN) stipulates that it is ideal to know census size

Distribution of the brown bear (Ursus arctos marsicanus) in the Central Apennines, Italy, 2005-2014 [PDF]

open access: yes, 2017
Despite its critical conservation status, no formal estimate of the Apennine brown bear (Ursus arctos marsicanus) distribution has ever been attempted, nor a coordinated effort to compile and verify all recent occurrences has ever been ensured.

Degenerate quantum gases of strontium

open access: yes, 2014
Degenerate quantum gases of alkaline-earth-like elements open new opportunities in research areas ranging from molecular physics to the study of strongly correlated systems. These experiments exploit the rich electronic structure of these elements, which

Mating systems and sexual selection in male-pregnant pipefishes and seahorses: insights from microsatellite-based studies of maternity. [PDF]

open access: yes, 2001
In pipefishes and seahorses (family Syngnathidae), the males provide all postzygotic care of offspring by brooding embryos on their ventral surfaces. In some species, this phenomenon of male "pregnancy" results in a reversal of the usual direction of ...
