BUSCADOR RECOLECTA

Peer reviewed

Data are organized in three independent files. (1) Breeding_parameters_Espartar_2014_2018.csv records the reproductive parameters (hatching success (HS), fledgling success (FS) and breeding success (BS)) of all accessible nests of storm petrels at s’Espartar islet (Ibiza, Balearic Islands) during breeding seasons 2014 to 2018. First columns correspond to year (2014 to 2018), colony, nest number and zone of the study nests. Zone was coded as “C” = Chambers and “E” = Entrance. Last three columns (F, G and H) gather reproductive parameters HS, FS and BS being 0 if fails and 1 if successful. (2) Data_nestlings_BC_ticks_Espartar_2018.csv contains the state, the number of ticks attached to nestlings, their maximum number, biometric measurements and the estimated age of nestlings of storm petrels at s’Espartar (Ibiza, Balearic Islands) during breeding season in 2018. This file may contain more than one record (line) per individual because some nestlings were inspected multiple times. First column indicates the zone of the nest (“C” = Chambers and “E” = Entrance), next column corresponds to the nest number (= nestling number) followed by state and the state of the next inspection (state_t+1) of the nestling; these columns indicate if nestling is alive or dead. Columns F and G correspond to the number of ticks in each inspection and the maximum number of ticks found among all inspections respectively; last columns are the measurements of the wing length (mm), tarsus (mm), body mass (g) and estimated age of each nestling inspection. (3) Data_Adults_Espartar2018.csv contains the information about breeding adults of storm petrels from the entrance and chambers of the s’Espartar cave (Ibiza, Balearic Islands) during the breeding season in 2018. This file contains one line per individual being the first column the date of inspection, followed by the zone of the nest, the number of nest, and the ring code of the each individual; and the last three columns (E, F, G) correspond to the biometric measurements of tarsus, wing length and body mass (weight). Missing values in all datasets were coded as “NA”., Dataset (1) was used to analyze reproductive parameters of Storm petrels at S’Espartar islet (Ibiza, Balearic Islands) from 2014 to 2018. Dataset (2) was used to study the number of ticks (tick load) attached on nestlings and how affect them to their body condition depending on the zone where they are found during the breeding season in 2018. Dataset (3) was used to study if exists differences between adults of the different zones of the study area during the breeding season in 2018., This project was partially funded by the Govern Balear (Acciones Especiales, AAEE031/2017) and the Spanish Ministry of innovation and Universities (RESET, ref: CGL2017-85210-P)., No

Data are organized in two independent files: (1) “Burrowing_Owl_Data.xlsx” records all the information of burrowing owls ringed during a monitoring program at Bahia Blanca (Argentina) during the breeding seasons 2005/2006 - 2017/2018. Each line corresponds to one individual. The dataset includes the year of birth and the year of first resight, the natal dispersal distance, the sex, the flight initiation distance (FID) and the breeding productivity both in the first breeding attempt and during the entire life for each individual. We also provide information about the habitat type, the conspecific density and the conspecific productivity both for their natal area and for their first breeding territory.-- (2) “dispnatalsurvival.inp” records the recaptures of each marked burrowing owls during a continuous monitoring program, grouped by sex and habitat. Each line corresponds to one individual. The first 11 columns represent the history of life of the individuals by years (with 0 = no resight and 1= resight). The following 4 columns are the groups (urban males, urban females, rural males, rural females), and the last column is the natal dispersal distance (log transformed) covered by each burrowing owl., Dataset (1) was used to analyze how different individual and social traits influence the natal dispersal distances of burrowing owls and how the variation in the dispersal distances can influence breeding productivity. Dataset (2) was used to study how dispersal distances can influence survival in male and females burrowing owls living in urban and rural habitats., The project was funded by Projects CGL2012-31888 and CGL2015-71378-P from MINECO (Spain) and Fundación Repsol.

Female birds can influence offspring development by adjusting egg size or by a differential allocation of egg resources. Such maternal effects can be expected to be shaped by natural selection, given the costs connected to the allocation of maternal resources. Among egg components, yolk androgens play an important role in affecting offspring life-history traits. Despite their relevance for nestling development, factors accounting for the observed within- and between-clutch variation are still poorly known. By using a cross-sectional sampling approach, we tested the effect of female age, laying order and laying date on the deposition of yolk androstenedione (A4) and testosterone (T), since young and older females could maximize their fitness differently according to breeding conditions. We found a remarkable lack of differences in overall yolk androgen levels across different ages. However, comparing first-year with older females, our results showed that age did not influence yolk T levels at the beginning of the breeding season, whereas at the end first-year females transferred lower hormone levels than older females. Within clutches, both androgens increased across the laying sequence, suggesting that late nestlings benefit from an increased allocation that could compensate hatching asynchrony. However, when considering A4 we found that, whereas older females always increased A4 levels across the laying sequence, first-year females did not increase it at the end of the breeding season, thus increasing the likelihood of brood reduction when environmental conditions became hardest. These findings suggest that yolk A4 variation may be particularly important at the within-clutch scale, by providing females with a tool to modify nestling hierarchies., The project was funded by projects CGL2011-26318 to DG (Ministerio de Economía y Competitividad) and PGC2018-099596-B-I00 to LP-R (Ministerio de Ciencia, Innovación y Universidades, co-financed by the European Regional Development Fund -ERDF).

The data file contains data on Canary Island date palms Phoenix canariensis located in public gardens within Palma city and monitored between 2011 and 2017. We coded yearly observations on each palm (first seven columns on the excel file) into individual histories using the four following codes: 1 = palm tree apparently healthy (i.e. with no signs of weevil infestation); 2 = palm tree infested by red palm weevil and treated with a partial pruning (i.e. curative treatment); 3 = palm tree infested by red palm weevil and treated with a total cut (i.e. destructive treatment);0 = palm tree that no longer exist due to a destructive treatment applied the previous year. Columns 8 to 15 indicate the individual covariates used as linear predictors of infestation probabilities: the number of palms (P. canariensis and P. dactylifera) within a 500 m radius from each palm monitored. We sorted palms into public (“public”, i.e. those directly managed by the city council) and private (“priv”), differentiating in this last case between palms under the responsibility of other governmental entities (e.g. schools, namely “ent”) and those belonging to particular owners in private areas (e.g. hotels or other private gardens, namely “part”)., This dataset was used to analyze the infestation probabilities of Canary Island date palms by Red palm weevils., We acknowledge financial support through projects ‘Vicenç Mut’ PD/003/2016 and Ramón y Cajal RYC-2017- 22796., Peer reviewed
