A family of null models to distinguish between environmental filtering and biotic interactions in functional diversity patterns
We argue that the traditional null model approach can only identify a single main process at a time and suggest to rather use a family of null models to disentangle intertwined assembly processes acting across spat...

The quest for trait divergence and convergence: are null-models the magic wand?
The paper shows that null models should be more thoroughly described and validated before being considered as a magic wand to reveal assembly patterns....

Tooth development in a model reptile: functional and null generation teeth in the gecko Paroedura picta
This paper describes tooth development in a basal squamate, Paroedura picta. Due to its reproductive strategy, mode of development and position within the reptiles, this gecko represents an excellent model organism for the study of reptile d...

Null model analyses of temporal patterns of bird assemblages and their foraging guilds revealed the predominance of positive and random associations
null models on assemblage and guild levels. These null model outcomes were further of the null models. The analysis of two binary null models in combination with three of the qu...

The paradox of energy equivalence
, the independence of mass and energy flux is a null hypothesis. We show that our mechanistic understanding of sizedensity relationships (SDRs) follows directly from this null model an expression for the strength (r 2) of S...

Testing the adequacy of semiparametric transformation models
We consider a semiparametric model whereby the response variable following a transformation can be expressed by means of a regression model. In this model, the form the regression function is completely unknown. We develop ...

Change point detection
This contribution deals with tests on the stability of statistical models. The problem is formulated in terms of testing the null hypothesis against the alternative hypothesis. The null hypothesis claims that the model<...
