Data from: Black goby territorial males adjust their ejaculate’s characteristics in response to the presence of sneakers
In many species males can rapidly adjust their ejaculate performance in response to changing levels of sperm competition, an ability that is probably mediated by seminal fluid adaptive plasticity. In the black goby, Gobius niger, female spawning in the nest of a territorial male can last hours, and males attach a viscous ejaculate to the nest roof, from which sperm are slowly released. During spawning, sneaker males attempt to approach the nest and release their sperm, and territorial males intensify their defensive effort at the increasing of sneaking pressure. We show here that territorial males adjust the characteristics of their seminal fluid in response to the number of competitor sneakers. Territorial males produce an ejaculate from which sperm are released at a rate that decreases as the number of surrounding competitor sneakers increases. Field observations showed that multiple sneaking attempts occurred sequentially, forcing territorials to frequently leave the nest. Overall these results suggest that the adjustment of seminal fluid viscosity may guarantee a continuous release of sperm from the ejaculate, although at a lower rate, when the territorial male is engaged in prolonged nest defense possibly minimizing the postcopulatory cost of an increased precopulatory mate guarding

Relative numerical middle in rhesus monkeys
Animals show vast numerical competence in tasks that require both ordinal and cardinal numerical representations, but few studies have addressed whether animals can identify the numerical middle in a sequence. Two rhesus monkeys (Macaca mulatta) learned to select the middle dot in a horizontal sequence of three dots on a touchscreen. When subsequently presented with longer sequences composed of 5, 7 or 9 items, monkeys transferred the middle rule. Accuracy decreased as the length of the sequence increased. In a second test, we presented monkeys with asymmetrical sequences composed by nine items, where the numerical and spatial middle were distinct and both monkeys selected the numerical middle over the spatial middle. Our results demonstrate that rhesus macaques can extract an abstract rule to bisect a discrete set of items

Approach direction or response times? A new measure for spatial numerical association in the day-old domestic chick (Gallus gallus) Hemispheric processing of spatial numerical information
Chicks trained to identify a target item in a sagittally-oriented series of identical items showed a higher accuracy for the target on the left, rather than that on the right, at test when the series was rotated by 90°. Such bias seems to be due to a right hemispheric dominance in visuospatial tasks. Up to now, the bias was highlighted by looking at accuracy, the measure mostly used in human studies to detect spatial numerical association, SNA. In the present study, processing by each hemisphere was assessed by scoring three variables: Accuracy, Response Times and Direction of Approach. Domestic chicks were tested under monocular vision conditions, as in the avian brain input to each eye is mostly processed by the contralateral hemisphere. Four-day-old chicks learnt to peck at the 4th element in a sagittal series of 10 identical elements. At test, when facing a left-to-right-oriented series, birds confined their responses to the visible hemifield, with high accuracy for the 4th element. The first element in the series was also highly selected, suggesting an anchoring strategy to start the proto-counting at one end of the series. In the left monocular condition, chicks approached the series starting from the left, and in the right monocular condition, they started from the right. Both hemispheres appear to exploit the same strategy, scanning the series from the most lateral element in the clear hemifield. Remarkably, there was no effect in the Response Times: equal latency was scored for correct or incorrect and for left vs. right responses.
Overall, these data indicate that the measures implying a direction of choice, Accuracy and Direction of Approach, and not velocity, i.e., Response Times, can highlight SNA in this paradigm. We discuss the relevance of the selected measures to unveil SNA

This collection includes all raw shot gathers collected around the Scrovegni Chapel the 29th October 2020 (data are in SEGD format). This dataset is the result of the collaboration between the University of Padova, that performed the data acquisition, and STRYDE, that provided the seismic nodes and the technical support
2019 Dataset of Participatory Budgeting in Italy
The dataset provides data on Italian Municipalities’ policies pertaining to participatory budgeting (PB). The dataset comprises information on municipalities with a population of over 2,000 inhabitants, and is composed as follows: Municipality ISTAT Code (ID), Municipality Name (MN) Province, Region, Population (2011 Census), Researcher (IR), Mapping randomized process (MR), Mapping Method (MM), twenty dummy variables identifying Municipalities running PB in a given year (y1994, y2002 to y2020), Number of years with PB (TOT).
Overall, the dataset comprises 4517 units (with 467 missing), for a total of 4050 mapped municipalities
