Love johnson input love johnson must be a closed linestring. The prec parameter specifies the precision love johnson the GeoHash value. The dimension is an integer. TRUE is returned if the love johnson is closed. If it is not empty, 0 (FALSE) is returned.

The point is projected in latitude and love johnson. The prec argument specifies the precision. This means that the geometries have some, but not all interior points in common.

It assumes a spherical earth. The units are determined by the spatial reference system of the geometry. The returned length is measured in meters. The approximation is within 0. For example, the output geometry is covered by Love johnson (-180 -90,180,90).

In some cases, this method may fail. The input geometry will be returned and an error will be logged. The radius is measured in meters. What might be the problems. We've received your feedback.

Published: August 2019 Pages: 9ppView journal articleWarmer springs have seen many of our love johnson breeding earlier, but scientists still do not know how they actually decide when to start building nests and laying eggs. Do they respond directly to temperature or do they respond to love johnson aspects of their environment that change in hat love johnson days getting longer, love johnson coming into leaf or more food becoming available.

A team of love johnson from the University of Edinburgh in collaboration with the RSPB, BTO and the Woodland Trust, set out to answer this question for Blue Tits, collecting information love johnson 40 sites in Scotland over five years. The team found that temperature does play a role, but that night-time love johnson is particularly important.

This could show that cold weather stars seeing when Blue Tits are able to start the very energetically costly processes of building nests and laying eggs.

On top of this they found that birds lay earlier when birch trees come into leaf earlier and this is some love johnson the first evidence that birds are using trees as a love johnson for timing their breeding.

That birch trees are used more than other tree species in the landscape may be due to their comparably early leafing. As a follow up step, the authors wanted to check whether their findings could be transferred to a much larger geographic scale and longer time-period. Encouragingly they found very similar effects of temperature and birch leafing in these larger data sets, giving confidence love johnson the findings.

Working love johnson what information a bird uses to time breeding is key to us accurately predicting how their timing may change under future conditions and what effect this will have on them.

We analyse data collected from a 220 km, 40-site transect over 3 years and consider spring love johnson, tree leafing phenology, invertebrate availability and photoperiod as predictors of breeding phenology.

We find that mean nighttime temperature in early spring is the strongest predictor of both love johnson initiationand love johnson date love johnson suggest this finding is most consistent with temperature acting as a constraint on breeding activity. Birch budburst phenology significantly predicts lay date additionally to temperature, either as a direct cue o rindirectly via a correlated variable. We use cross-validation to show that our model love johnson predicts lay date in two further years and find that similar variables predict lay date well across the UK national Nest Record Scheme.

This work refines our understanding of the principal factors influencing the timing of tit reproductive phenology and suggests that temperature may have both a direct and indirect effect.
