An unexpectedly vital part of the ecology

The disappearance of frogs and toads contributes to the appalling modern phenomenon that conservationists are now encountering everywhere: “trophic cascade”.

What is it with poets, frogs and toads? “Stop looking like a purse,” says the poet Norman MacCaig, carrying a toad outside. “How could a purse/squeeze under the rickety door and sit,/full of satisfaction, in a man’s house?” The pair of toads Jamie McKendrick encounters find their own exit: “they make for the hallway with sagging hops/like small encrusted beanbags on the move”, he says in “Right of Way”.

Frogs and toads live on all continents except Antarctica, in 24 different families and more than 4,000 species. In children’s literature they are gently comical, but the amphi in amphibian reminds us that they belong to two worlds.

They disappear in a second, leaping from one medium into another, and global folklore invests them with darker powers than Kenneth Grahame. A life cycle of spawn, tails and legs means they incarnate metamorphosis: you kiss them into princes, get turned into one by witches. In the Rig Veda, Great Frog supports the universe. They are familiars, boiled up by the Weird Sisters in Macbeth, and the “great kings” of slime terrify the boy in Seamus Heaney’s “Death of a Naturalist”.

Frogs and toads are an unobtrusive but vital part of the ecology, and their loss contributes to the appalling modern phenomenon that conservationists are now encountering everywhere: “trophic cascade”.

As children, we used to put bricks up on end in a long wavy line, then tip the first and watch the whole circuit ripple to the ground. Imagine a similar sequence in a South American forest, with frogs at its centre. The frogs live in delicate balance with nine other species: lizards, mango trees, mango-eating ants, monkeys, wild pigs, owls, wasps, mosquitoes and a microbial parasite. They breed in riverbank puddles created by the rootling wild pigs. Mosquitoes breed in those puddles, too. The parasite they carry infects monkeys that eat the mango fruit, spreading its seed in fertilising scat, but few monkeys die, because the frogs’ tadpoles eat most mosquito larvae.

The lizards eat the ants; they also eat wasps that nest in holes in trees. Owls compete for these nesting holes and keep the wasps in check.

Now men kill off the pigs. No more puddles – so the frogs die out, but the mosquitoes breed in rainwater instead. Uneaten, they multiply, along with their parasites, which kill off the monkeys. With no monkey-scat, the mango trees die, along with the mango-eating ants. This halves the lizards’ food and they fade away. No lizards means more wasps, which crowd the weakening owls out of nesting sites. The owls go. Only three viable species are left: wasps, mosquitoes and their parasite, which will now turn on the cause of all this - man.

Trophic cascade could happen here. Frogs are disappearing globally into extinction. Two diseases are ravaging amphibians worldwide. Chytrid fungus has extinguished hundreds of species, and thousands of British frogs are dying from ranavirus.

Conservationists are working against time to save them. Scientists from the Zoological Society of London have swabbed amphibians in ponds across the UK and are collaborating with other organisations on the Garden Wildlife Health website, which asks for the public’s help in monitoring British wildlife. ZSL has also rescued, through a unique conservation programme you can see in action at Regent’s Park, the Majorcan midwife toad – until 1979 believed extinct – whose males carry new-laid spawn on their back until the tadpoles hatch.

Glyn Maxwell has written a poem to these toads, not now entering human houses but being saved – just – by human beings from exiting the world. “We are back who were never gone,” they sing. “We were here and you never knew./We thought you’d died out too.”

Next week: Felicity Cloake on food

How power shifted dramatically in this week’s Game of Thrones

The best-laid plans of Mothers and men often go awry.

Last week’s Game of Thrones was absolutely full of maps. It had more maps than a Paper Towns/Moonrise Kingdom crossover. More maps than an Ordnance Survey walking tour of a cartographer’s convention. More maps than your average week on CityMetric.

So imagine the cheers of delight when this week’s episode, “Stormborn”, opened with – yes, a map! Enter Daenerys, casting her eyes over her carved table map (Ikea’s Västeross range, I believe), deciding whether to take King’s Landing and the iron throne from Cersei or a different path. After some sassy debates with Varys over loyalty, more members of her court enter to point angrily at different grooves in the table as Dany and Tyrion move their minature armies around the board.

In fact, this whole episode had a sense of model parts slotting pleasingly into place. Melisandre finally moved down the board from Winterfell to Dragonstone to initiate the series’ most inevitable meeting, between The King of the North and the Mother of Dragons. Jon is hot on her heels. Arya crossed paths with old friends Hot Pie and Nymeria, and the right word spoken at the right time saw her readjust her course to at last head home to the North. Tyrion seamlessly anticipated a move from Cersei and changed Dany’s tack accordingly. There was less exposition than last week, but the episode was starting to feel like an elegant opening to a long game of chess.

All this made the episode’s action-filled denouement all the more shocking. As Yara, Theon and Ellaria dutifully took their place in Dany’s carefully mapped out plans, they were ambushed by their mad uncle Euron (a character increasingly resembling Blackbeard-as-played-by-Jared-Leto). We should have known: just minutes before, Yara and Ellaria started to get it on, and as TV law dictates, things can never end well for lesbians. As the Sand Snakes were mown down one by one, Euron captured Yara and dared poor Theon to try to save her. As Theon stared at Yara’s desperate face and tried to build up the courage to save her, we saw the old ghost of Reek quiver across his face, and he threw himself overboard. It’s an interesting decision from a show that has recently so enjoyed showing its most abused characters (particularly women) delight in showy, violent acts of revenge. Theon reminds us that the sad reality of trauma is that it can make people behave in ways that are not brave, or redemptive, or even kind.

So Euron’s surprise attack on the rest of the Greyjoy fleet essentially knocked all the pieces off the board, to remind us that the best-laid plans of Mothers and men often go awry. Even when you’ve laid them on a map.

But now for the real question. Who WAS the baddest bitch of this week’s Game of Thrones?

Bad bitch points are awarded as follows:

  • Varys delivering an extremely sassy speech about serving the people. +19.
  • Missandei correcting Dany’s High Valerian was Extremely Bold, and I, for one, applaud her. +7.
  • The prophecy that hinges on a gender-based misinterpretation of the word “man” or “prince” has been old since Macbeth, but we will give Dany, like, two points for her “I am not a prince” chat purely out of feminist obligation. +2.
  • Cersei having to resort to racist rhetoric to try and persuade her own soldiers to fight for her. This is a weak look, Cersei. -13.
  • Samwell just casually chatting back to his Maester on ancient medicine even though he’s been there for like, a week, and has read a total of one (1) book on greyscale. +5. He seems pretty wrong, but we’re giving points for sheer audacity.
  • Cersei thinking she can destroy Dany’s dragon army with one (1) big crossbow. -15. Harold, they’re dragons.
  • “I’ve known a great many clever men. I’ve outlived them all. You know why? I ignored them.” Olenna is the queen of my LIFE. +71 for this one (1) comment.
  • Grey Worm taking a risk and being (literally) naked around someone he loves. +33. He’s cool with rabid dogs, dizzying heights and tumultuous oceans, but clearly this was really scary for him. It’s important and good to be vulnerable!! All the pats on the back for Grey Worm. He really did that.
  • Sam just fully going for it and chopping off all of Jorah’s skin (even though he literally… just read a book that said dragonglass can cure greyscale??). +14. What is this bold motherfucker doing.
  • Jorah letting him. +11.
  • “You’ve been making pies?” “One or two.” Blatant fan service from psycho killer Arya, but I fully loved it. +25.
  • Jon making Sansa temporary Queen in the North. +7.
  • Sansa – queen of my heart and now Queen in the North!!! +17.
  • Jon choking Littlefinger for perving over Sansa. +19. This would just be weird and patriarchal, but Littlefinger is an unholy cunt and Sansa has been horrifically abused by 60 per cent of the men who have ever touched her.
  • Nymeria staring down the woman who once possessed her in a delicious reversal of fortune. +13. Yes, she’s a wolf but she did not consent to being owned by a strangely aggressive child.
  • Euron had a big win. So, regrettably, +10.

​That means this week’s bad bitch is Olenna Tyrell, because who even comes close? This week’s loser is Cersei. But, as always, with the caveat that when Cersei is really losing – she strikes hard. Plus, Qyburn’s comment about the dragon skeletons under King’s Landing, “Curious that King Robert did not have them destroyed”, coupled with his previous penchant for re-animated dead bodies, makes me nervous, and worry that – in light of Cersei’s lack of heir – we’re moving towards a Cersei-Qyburn-White Walkers alliance. So do watch out.
