Speed measurements made by Division "A" of the airplane director [PDF]
The various speeds of an airplane can only be measured in horizontal flight, since there are no means for measuring the angle of ascent or descent. The measurements must be corrected for the density of the air.

Wildlife Biology, EarlyView.Human disturbances are threatening biodiversity worldwide, and species with restricted geographic distribution or small population sizes are more likely to become extinct. The prevention of extinctions is an urgent matter and knowledge on the ecology and distribution of threatened species is required to outline conservation strategies.

Bat Tongues and Foraging: Linking Morphology to Hunting Strategies
Integrative Zoology, EarlyView.We linked the bat tongue's mediodorsal lobe (MDL), a muscular prominence, to foraging strategies. Aerial hawkers exhibit tall MDLs and prominent forward‐pointing papillae. The MDL may function as a barrier or filter, preventing unintentional ingestion of non‐food material, aiding in prey handling, and controlling food access during fast flight ...

Annals of Applied Biology, EarlyView.Triticale and lupin are promising candidates for sustainable intercropping in low‐input, mixed crop–livestock farming systems in the Mediterranean basin, where they can be grown as rain‐fed crops during the autumn‐winter period. A field trial conducted in Sardinia demonstrated several key findings: the slower canopy development and shorter stature of ...

Animal Conservation, EarlyView.To supply high demand for exotic pets, animals are harvested illegally from the wild and laundered as captive bred. However, there are currently limited methods to identify captive or wild origins of wildlife. We assessed the accuracy of stable isotope analysis of feathers to identify differences in diets, and therefore captive and wild origins, of ...

Effects of aircraft and flight parameters on energy-efficient profile descents in time-based metered traffic [PDF]
The influence of several parameters on the time required to fly a nominal profile descent of a B-737 from an entry fix to a metering fix 75 n.mi. away was studied.

Cossid moths (Lepidoptera: Cossidae) as pests of woody plants – A review
Agricultural and Forest Entomology, EarlyView.Abstract The Cossidae is a worldwide family of macro‐moths popularly known as carpenter moths due to the larval habit of boring in the wood of living plants. This review compiles current knowledge on the characteristics, diversity and bionomy of cossid moths as well as the damage they cause on woody plants.

Agricultural and Forest Entomology, EarlyView.Wildfire and intensive site preparation influence beetle assemblages by shaping habitat heterogeneity, with wildfire fostering biodiversity while disc trenching leads to long‐term species declines due to habitat homogenization. Post‐fire beetle succession follows a predictable trajectory, with early successional species dominating open habitats and ...

Agricultural Economics, EarlyView.ABSTRACT The core of Colombia's coffee growing region was designated as a World Heritage (WH) site in 2011, making a distinction between “the core” of the region and “the periphery.” However, the coffee cultural heritage does not abruptly stop at the WH boundary but it exists inside and outside the boundary.
