1/15 Hello y’all! I’m thrilled to be one of the plenary presenters at #AnimBehav2021 and to share with you some of the research that we’ve been doing recently on #poisonfrogs, both in the lab at @jyuscience and in the field at @RNNouragues Follow the

2 Offspring survival is highly dependent on the environment that parents select or create for them, particularly in species with external fertilisation. Thus, many animals have evolved ways to assess the quality of the sites where their young will be reared #AnimBehav2021

with eggs & tadpoles in large water bodies are the most common. These sites have 
food but also predation. Other have terrestrial reproduction, which entails 
predation but also food & desiccation risk. For many of them, #parentalcare is key! #AnimBehav2021

5 Do dads take tadpoles to the nearest pool available? if not, how far? We equipped with tiny transmitters to follow their trajectories in the rainforest (see how in the 
) and found that actually go farther —dozens of m from home! http://rb.gy/xcbwye #AnimBehav2021

6 Dads can also go really far on the vertical landscape. Tadpoles of D. tinctorius have been found up to 20+ m up in canopy treeholes. So, can climb ~500 times their own body length 
That's as if I climbed a giant ~800m+ high tree #AnimBehav2021

7 Are under a predation risk while climbing up? We exposed clay models on tree trunks and on the leaf litter to wild 
predators to test whether the former were more 'attacked'. We found no evidence of increased predation attempts on 'climbing'

8 What pool properties predict the presence of D. tinctorius tadpoles? They are most likely to be in high pools with levels of salinity, alkalinity (inhibits fungal growth) and insect diversity (food?), but the range of suitable properties is surprisingly wide! #AnimBehav2021

9 Other species can occupy these pools too, but there seems to be some vertical segregation. D. tinctorius, in contrast, can occupy pools across all the vertical gradient. If that's the case, why bother taking tadpoles so high up? #AnimBehav2021

10 Canopy pools are often occupied by treefrogs which mate and lay their (hundreds of) eggs in them. These can make a succulent meal for the carnivorous Dt tadpoles. We don't know how Dt find these high pools —maybe they eavesdrop on the treefrogs' calls?

11 What do they eat in lower pools? Dt tadpoles are voracious carnivores which can eat insect larvae & 
/tadpoles of any other species, but also of their own! Newly-deposited tadpoles can be eaten promptly when larger conspecifics are already in the pool #AnimBehav2021

12 Surely if dads can choose, they'd deposit tadpoles in empty pools rather than occupied ones, right? Wrong! 
Given the choice, deposit their tadpoles in pools occupied by large conspecifics: likely, these are a cue of pool quality http://rb.gy/q3kcra #AnimBehav2021

13 Do they eat *any* conspecific? Also relatives? Possibly 
So far we know that aggression, a precursor of cannibalism, is lower towards kin than towards non-kin, but the onset of aggression depends on relatedness AND diff in size http://rb.gy/r0jrr0 #AnimBehav2021

14 We are beginning to understand what are the criteria that Dt use to pick the nurseries for their tadpoles and how these thrive there, sometimes at the expense of killing conspecifics. Next: bringing kin recognition and pathogen transmission into the picture. #AnimBehav2021
