Observational constraints on tidal effects using orbital eccentricities

open access: yes, 2012
We have analysed radial velocity measurements for known transiting exoplanets to study the empirical signature of tidal orbital evolution for close-in planets.

WASP-29b: A Saturn-sized transiting exoplanet [PDF]

open access: yes, 2010
We report the discovery of a Saturn-sized planet transiting a V = 11.3, K4 dwarf star every 3.9 d. WASP-29b has a mass of 0.24+/-0.02 M_Jup and a radius of 0.79+/-0.05 R_Jup, making it the smallest planet so far discovered by the WASP survey, and the ...

From cities to refuges for pollinators: Urban practices for enhancing pollinator habitats in changing landscapes

open access: yesJournal of Applied Ecology, EarlyView.
A framework for the support of pollinators in urban areas is developed here, based on five pillars: nesting, flower resources, artificial support, management and society acceptance, with additional key elements from science and society. Society should incorporate strategies for pollinators as in this framework by means of co‐planning with stakeholders,

Effects of Different Habitats on the Productivity of the Native Paper Wasp Polistes Fuscatus and the Invasive, Exotic Paper Wasp P. Dominulus (Hymenoptera: Vespidae)

open access: yesGreat Lakes Entomologist, 2018
We examined the colony productivities of the native paper wasp, Polistes fuscatus (Fab.),(Hymenoptera: Vespidae), and the invasive, exotic paper wasp, P.

Homogeneously derived transit timings for 17 exoplanets and reassessed TTV trends for WASP-12 and WASP-4 [PDF]

open access: yes, 2019
19 pages, 4 figures, 6 tables; revised manuscript submitted to MNRAS; online-only supplements are in the download archiveWe homogeneously analyse ∼3.2 × 10 5 photometric measurements for ∼1100 transit light curves belonging to 17 exoplanet hosts.

Using total abundance as a proxy for wild bee species richness: A practical tool for non‐experts

open access: yesJournal of Applied Ecology, EarlyView.
The use of a simple but effective proxy could be an important starting point for the expansion of wild bee monitoring initiatives at the regional scale, particularly given the growing involvement of non‐specialists. We provided here a simple implementation framework to use this proxy in rapid biodiversity assessments, such as the evaluation of payment ...

Associative Learning of Food Odors by the European Paper Wasp, Polistes dominula Christ (Hymenoptera: Vespidae).

open access: yesEnvironmental Entomology, 2018
We investigated associative learning of food odors by the European paper wasp Polistes dominula Christ (Hymenoptera: Vespidae) because of consistent low rates of attraction to food materials in laboratory assays.

Polarization in exoplanetary systems caused by transits, grazing transits, and starspots

open access: yes, 2015
We present results of numerical simulations of flux and linear polarization variations in transiting exoplanetary systems, caused by the host star disk symmetry breaking.

Mixed plant and arthropod biodiversity responses to solar park establishment on former agricultural lands

open access: yesJournal of Applied Ecology, EarlyView.
Our results suggest that while biodiversity can increase in solar parks post‐conversion compared to previous land use, not all taxonomic groups benefit from the land use change. Potential benefits for certain groups (particularly for butterflies and soil‐emergent arthropods) are likely lost due to disturbance during land conversion and solar panel ...

Constraints, Lazy Constraints, or Propagators in ASP Solving: An Empirical Analysis

open access: yes, 2017
Answer Set Programming (ASP) is a well-established declarative paradigm. One of the successes of ASP is the availability of efficient systems. State-of-the-art systems are based on the ground+solve approach.
