Many spider species show large differences in size between males and females, but biologists still do not fully understand how or why...

Sexual cannibalism — the consumption of one mating partner by the other before, during, or after copulation — is documented across...

Animal personalities - consistent behavioral tendencies - can play an important role in mating decisions. This study tests the idea that...

The objective of our project is to provide a robust scientific framework for testing organismal spread and invasion. Our model organisms...

Bark spiders (genus Caerostris ) are large spiders distributed across the Old-World tropics. Caerostris are characterized by   web...

We report a sequence of unusual male behaviors observed in the spider species Nephila pilipes (family Nephilidae), a sexually size...

A longstanding question in evolutionary biology is how within-population phenotypic variation is maintained under natural selection. The...

Pisauridae - nursery-web spiders - are a global and heterogeneous assemblage of spider genera with diverse morphologies and lifestyles....

Dolomedes  may easily be considered to be among the most charismatic spider taxa. Known colloquially as fishing or raft spiders, this...

In this study, we focus on Coenonympha oedippus , an endangered butterfly species protected under Annexes II and IV of the EU Habitats...

Sexual size dimorphism theory predicts biased operational sex ratios (OSRs) and an uneven distribution of males among certain females. We...

The ideal free distribution (IFD) theory predicts that individuals are free to move among habitat patches and distribute among them...

Predators often search for prey while moving through the environment, but there are important exceptions, including the way sedentary...

Ants and termites are insect groups that make up most of the insect biomass in tropical ecosystems. Due to their social structure and...

Noticeable declines in insect populations have become of concern. Among the system services that functioning ecosystems provide,...

Madagascar is well known for its diverse and unique biota. The combination of a unique geological history of Madagascar and its long...

We delved into the fascinating world of Dolomedes fimbriatus, a spider species with significant size differences between females and...

It is generally thought that mating plugs, where present, impede or reduce the possibilities of female subsequent mating. However, mating...

We report the first finding of the stygobiotic form of the cyprinid fish Garra rufa (Heckel, 1843), discovered in a single locality in...

Spiders are successful predators that inhabit nearly all kinds of terrestrial and even freshwater habitats. However, only a handful of...
