Abstract BACKGROUND Olive maturity governs lot destination and the yield–quality trade‐off in olive oil production, yet it is still monitored by subjective visual scoring of the Jaén index. Spectroscopic alternatives have relied mainly on near‐infrared instruments, with scarce evidence from Brazilian orchards and almost no evaluation of spatial or ...

We estimated the distribution of the federally threatened wolverine (Gulo gulo) across the western United States in 2022, evaluated changes in distribution since 2017 (the last survey), and made inference on drivers of wolverine occurrence. This monitoring program and subsequent results are used by states to make management and conservation decisions ...

Fine‐scale population variables better explain roadkill patterns in natterjack toads (Epidalea calamita) than habitat proxies, with mortality driven mainly by local abundance, reduced by roadside embankments, and decreasing as the season advanced. Despite high roadkills, population viability analyses indicate no immediate extinction risk under current ...

Herbicide impacts on exotic grasses and a population of the critically endangered herb "Calystegia affinis" (Convolvulaceae) on Lord Howe Island [PDF]
Introduced perennial grasses are capable of altering the habitat of native species, causing reductions in population size and vigour, and potentially affecting life-history processes such as survival, pollination and seedling recruitment. We examined the

Caribou forage lichens were present in post‐burn lodgepole pine stands multiple decades before stem‐density was likely open enough to attract wintering caribou. We posit that the prolonged self‐thinning of lodgepole pine after fire may be a greater limiting factor than lichen abundance for habitat recovery in lodgepole pine forests.
