Abstract A major barrier to advancing ornithology is the systemic exclusion of professionals from Global South. recent special feature, Advances in Neotropical Ornithology, and a shortfalls analysis therein, unintentionally followed long-standing pattern highlighting individuals, knowledge, views North, while largely omitting perspectives people based within Neotropics. Here, we review current strengths opportunities practice ornithology. Further, discuss problems with assessing state...
Mutualisms often define ecosystems, but they are susceptible to human activities. Combining experiments, animal tracking, and mortality investigations, we show that the invasive big-headed ant (
Understanding the demography of an invasive species is crucial to better guide managers seeking slow spread invader. Habitat differences can affect demographic rates, which may in turn impact speed invasion, but this has been rarely addressed. We studied North American beavers (Castor canadensis) 2 contrasting habitat types island, forest and steppe, on Tierra del Fuego southern Patagonia. used repeated observations, mark-resight methods, telemetry, camera traps estimate colony size rates...
Abstract Although forest loss is still a problem worldwide, estimated rates of deforestation have declined in the last decade, primarily because an increase area tree plantations. This leads to central question how suitable plantations are for indigenous species. Native thought higher value biodiversity than non‐native trees; however, not all studies support this view. We assessed occupancy and density araucaria tit spinetail ( Leptasthenura setaria , Furnariidae), near threatened species,...
Biological invasions can lead to the reassembly of communities and understanding predicting impacts exotic species on community structure functioning are a key challenge in ecology. We investigated impact predatory invasive ant, Pheidole megacephala, function foundational mutualism between Acacia drepanolobium its associated acacia-ant an East African savanna. Invasion by P. megacephala was with extirpation three extrafloral nectar-dependent Crematogaster acacia ant strong increases...
Abstract Tephritidae fruit fly larvae develop entirely in the host chosen by females. To improve fitness of their progeny, females would benefit from rejecting previously exploited hosts. Anastrepha fraterculus and Ceratitis capitata are two species flies having similar nutritional requirements overlapping distribution. Previous studies found that competition between these might reach high levels, suggesting cross‐recognition be an adaptive trait. In this work, we tested ability A. C. to...
Research Highlights: Lodge abandonment by beavers is apparently a common phenomenon in Patagonia, but it still poorly understood and we ignore what drives it. In relatively slow growth Nothofagus forests, resource depletion can impact while water availability may be major driver the semiarid steppe. Background Objectives: North American beaver (Castor canadensis) was introduced 1946 on island of Tierra del Fuego (TDF) southern Argentina. Since then, have become disturbance affecting not only...
Many habitat-specialist organisms occur in distinct, patchy habitat, yet do not occupy all patches, and an important question is why apparently suitable habitat remains unoccupied. We examined factors influencing patch occupancy near-threatened, little-known Diademed Plovers ( Phegornis mitchellii ), arguably the bird most specialized to life High Andean peatlands. peatlands are well-suited modelling because they discrete patches of humid within a matrix high-altitude steppe. hypothesized...
La chinchilla de cola corta ha sido cazada hasta casi su extinción entre los siglos XIX y XX. En abril 2022 confirmamos la presencia poblaciones en provincia Salta, luego décadas sin registros visuales Argentina. Aquí, documentamos una nueva población Antofalla, Catamarca, 80 km al sudeste salteña. especie fue confirmada por fotografías obtenidas con trampas cámara. búsqueda remanentes Altos Andes es prioritaria para establecer situación actual e identificar potenciales áreas conservación.
