Direct evidence supporting Darwin's hypothesis of cross-pollination promoted by sex organ reciprocity. [PDF]
New Phytol, 2022 Summary The floral phenotype plays a main role in the attraction and fit of pollinators. Both perianth traits and the positioning of sex organs can be subjected to natural selection and determine nonrandom mating patterns in populations. In stylar‐polymorphic species, the Darwinian hypothesis predicts increased mating success between individuals with ...

Selection on tropane alkaloids in native and non-native populations of Datura stramonium. [PDF]
Ecol Evol, 2019 Here, we measured phenotypic selection on two chemical defense against herbivores (atropine and scopolamine) in native (Mexico) and non‐native (Spain) populations of Datura stramonium. Our results support the assumption that the reduction in plant defense in the absence of the plant's natural enemies in invasive ranges is driven by natural selection ...

Laboratory assessment of trilostane treatment in dogs with pituitary-dependent hyperadrenocorticism. [PDF]
J Vet Intern Med, 2020 Abstract Background Results of ACTH stimulation test (ACTHst), pre‐ and post‐trilostane serum cortisol concentrations (SCCs), urine concentration (urine‐specific gravity [USG]), and urine cortisol : creatinine ratios (UCCRs) are common variables used to monitor trilostane treatment of dogs with pituitary‐dependent hyperadrenocorticism (PDH).

Pest categorisation of Aleurocanthus spp. [PDF]
EFSA J, 2018 Abstract The Panel on Plant Health performed a pest categorisation of Aleurocanthus spp., a well‐defined insect genus of the whitefly family Aleyrodidae (Arthropoda: Hemiptera). Difficulties within the taxonomy of the genus give doubt about the ability to accurately identify some members to species level. Nevertheless, the genus is thought to currently

Global warming facilitates the nesting of the loggerhead turtle on the Mediterranean coast of Spain
Animal Conservation, Volume 26, Issue 3, Page 365-380, June 2023., 2023 Average summer sand temperature (July 20th–August 10th) at 40 cm deep in Spanish Mediterranean beaches, as reconstructed from air temperature at El Prat beach, has increased from 1950 to 2019 (top figure). As a result, the duration of the viable nesting window for loggerhead turtles (bottom figure) has also increased and the thermal environment has ...
