A multidisciplinary approach to estimating wolf population size for long‐term conservation

open access: yesConservation Biology, Volume 37, Issue 6, December 2023., 2023
Abstract The wolf (Canis lupus) is among the most controversial of wildlife species. Abundance estimates are required to inform public debate and policy decisions, but obtaining them at biologically relevant scales is challenging. We developed a system for comprehensive population estimation across the Italian alpine region (100,000 km2), involving ...

Contact chemoreceptive mate recognition in Cerambyx welensii Küster (Coleoptera: Cerambycidae) Mediación de la quimiorrecepción por contacto en el apareamiento en Cerambyx welensii Küster (Coleoptera: Cerambycidae)

open access: yesAgricultural and Forest Entomology, Volume 25, Issue 4, Page 622-636, November 2023., 2023
Abstract Cerambyx welensii Küster (Coleoptera: Cerambycidae) is a wood‐borer responsible for the decline of Mediterranean oaks in open woodlands. To establish that contact pheromones are involved in mate recognition of C. welensii, we extracted the cuticular hydrocarbons by solid phase microextraction at pre‐reproductive, beginning and ending of the ...

Fragmentation effects on an endangered species across a gradient from the interior to edge of its range

open access: yesConservation Biology, Volume 37, Issue 5, October 2023., 2023
Abstract Understanding how habitat fragmentation affects individual species is complicated by challenges associated with quantifying species‐specific habitat and spatial variability in fragmentation effects within a species’ range. We aggregated a 29‐year breeding survey data set for the endangered marbled murrelet (Brachyramphus marmoratus) from >42 ...

Cavity‐nesting birds are limited by nesting habitat in Neotropical agricultural landscapes

open access: yesBiotropica, Volume 55, Issue 5, Page 1045-1057, September 2023., 2023
Although cavity‐nesting bird diversity is highest in the tropics, little is known about how tropical birds use cavities, how agriculture affects their reproductive biology, and how effective nest boxes could be as a conservation strategy in tropical agriculture.

Effects of forest fragmentation on avian breeding activity

open access: yesConservation Biology, Volume 37, Issue 4, August 2023., 2023
Abstract Biodiversity declines and ecosystem decay follow forest fragmentation; initially, abundant species may become rare or be extirpated. Underlying mechanisms behind delayed extirpation of certain species following forest fragmentation are unknown.
