Our cover for issue 12 shows a green-eyed tree frog in Birthday Creek, Paluma, Queensland (photo credit: Richard Duffy). Frogs and other amphibians are susceptible to chytridiomycosis (caused by Batrachochytrium dendrobatidis (Bd)), which has taken a heavy toll on amphibian populations. In this issue, Greenspan et al’s paper Realistic heat pulses protect frogs from disease under simulated rainforest frog thermal regimes suggests that even where average temperatures are suitable for fungal growth and reproduction, infection risk and the outcome of existing infections may be heavily influenced by mild heat spikes only slightly higher than Bd’s thermal limits, providing support for management interventions that promote warm microenvironments for hosts. You can also read a Q&A with the lead author.
Also in this issue, Garnier et al talk about recurring issues (and their solutions) for interpreting ELISA analyses from wild animal samples, Powell et al explore context-dependent defences in turtle ants and Delgado-Baquerizo et al show how microbial richness and composition independently drive soil multifunctionality.
Our cover shows a tropical stonefly, an aquatic insect found in many rivers and streams (photo credit: Alisha A Shah). In the paper Climate variability predicts thermal limits of aquatic insects across elevation and latitude, Shah et al tested Janzen’s extension of the climate variability hypothesis, which posits that increased seasonal variation at high latitudes should result in greater temperature overlap across elevations, and favour wider thermal breadths in temperate organisms compared to their tropical counterparts, by measuring stream temperatures and thermal breadths for 62 aquatic insect species from temperate and tropical streams spanning an elevation gradient of c. 2000 m. They found that tropical aquatic insects have narrower thermal breadths than their temperate counterparts. Their findings suggest that lowland tropical insects may be the most vulnerable to climate change compared to other populations. Read the paper here and plain language research summary here.

Our cover image (photo credit: Ruben Heleno) comes from Rumeu et al’s paper, Predicting the consequences of disperser extinction: richness matters the most when abundance is low. In their paper, Rumeu et al assessed the functional consequences of defaunation on a seed dispersal network from the Galápagos Islands under five simulated extinction scenarios based on current threats to the archipelago biota. The authors found that both abundance and species richness of frugivores significantly affect the seed dispersal function (measured as the number of plant species dispersed after frugivore extinctions). The sequence of animal extinctions also has profound implications for the service available to the plant community. In the Galapagos, abundant species with generalist diets (like the lava lizard pictured here) can to a large extent mitigate the loss of more specialized dispersers and the early extinction of key generalist frugivores can lead to the rapid collapse of seed dispersal services. At the same time as generalist frugivores provide functional redundancy and secure high levels of seed dispersal, the identity of the species lost is also critical to understand the consequences for the number of plant species dispersed.

(This paper, and all our Reviews are free to read online).
Our cover image shows a liana in the forest canopy. Compared to trees, lianas have a much greater amount of leaves relative to their basal stem area (through which water flows). In their paper, Contribution of lianas to community‐level canopy transpiration in a warm‐temperate forest, Ichihashi et al showed that the contribution of lianas to forest water dynamics may be several times greater than their contribution to forest BA (or standing biomass), so a slight increase in liana abundance may have considerable effects on water dynamics and the capacity of forests to store carbon.

Our cover photo shows a humpback whales, mother and calf surfacing. To study their nursing behavior, Videsen et al. deployed non-invasive multi-sensor tags on eight young
humpback whale calves and two mothers. These tags (Dtags) record both depth, movement and sound data from the animals, providing unique and detailed insights into the lives of whales in the wild (see Videsen et al.’s High suckling rates and acoustic crypsis of humpback whale neonates maximise potential for mother–calf energy transfer).

This issue includes our Special Feature: The Ecology of De-Extinction. The next decade will see the cloning or genetic reconstruction of some version of a formerly extinct species; one that will live long enough to breathe and shake its fur, feathers, or scales, or to unfurl a leaf. A defensible objective for de-extinction is to seek some conservation benefit and a realistic conservation benefit is the restoration of lost ecosystem functions, but seeking benefits is not the same as achieving them. The six papers presented in this special feature have been selected to be a first attempt to consider the feasibility, desirability, and the implications of the translocation (movement and release) of resurrected forms with the aim of achieving some conservation benefit. We also have a new FE Spotlight from Richard Karban, "Plant communication increases heterogeneity in plant phenotypes and herbivore movement", looking at Morrell and Kessler's "Plant communication in a widespread goldenrod: keeping herbivores on the move" (both also in this issue).

Our cover image shows a vibrant coral reef in the Red Sea (photo taken by Stephanie Helber). Despite being located in oligotrophic waters, which offer little to sustain life, corals reefs such as this one maintain high productivity, in part due to efficient nutrient cycling. Sponges have recently been shown to recycle dissolved organic matter (DOM) on coral reefs by rapidly taking up DOM and transforming it into particulate detritus that can then be transferred up the reef food web. This "sponge loop" is proposed to play an important role in recycling the large quantities of DOM released by benthic primary producers, such as corals and algae. In their study, Rix et al. compare how reef sponges process the DOM produced by corals and algae and investigate how different DOM sources may influence DOM cycling via the sponge loop (see Rix et al., Differential recycling of coral and algal dissolved organic matter via the sponge loop).
Our latest FE Spotlight by Cleo Bertelsmeier, Functional trait ecology in the Anthropocene: a standardized framework for terrestrial invertebrates , looks at the importance of Moretti et al’s, Handbook of protocols for standardized measurement of terrestrial invertebrate functional traits. Also in this issue (and free to read), is Sheil et al’s Review Does biomass growth increase in the largest trees? Flaws, fallacies and alternative analyses
Our cover shows a Nidua fringe-ﬁngered lizard (Acanthodactylus scutellatus) - a lizard with cryptic pattern (photo by Dror Hawlena). In their paper, Movement correlates of lizards’ dorsal pigmentation patterns, Halperin et al suggested that species that forage less actively should have cryptic patterns while species that actively search for food should have stripes. Using an extensive literature survey, the authors found that lizards with stripes were substantially more active than lizards with cryptic patterns, providing the first quantitative support for the hypothesized relationships between pigmentation-patterns and foraging behaviour.
Also in this issue: in our latest FE Spotlight, New technology highlights the importance of scale in the foraging behaviour of a pelagic predator, Adrian Gleiss highlights the recent work by Adachi et al, Searching for prey in a three-dimensional environment: hierarchical movements enhance foraging success in northern elephant seals.

Issue 30.12 is out now and includes our new Special Feature: Advances and challenges in the study of ecological networks. Networks are collections of nodes that are connected to each other by links. Food webs, where nodes are species and links are feeding interactions (such as the Silvereye on our cover, Zosterops lateralis feeding on New Zealand ﬂax), are just one type of ecological network (Photograph by Timothée Poisot, CC-BY) (see paper by Poisot, pp. 1878–1882).
This Special Feature presents research at the frontier of what networks can do for ecologists, and outlines an ambitious research agenda to integrate network approaches into the standard ecological toolkit. As networks are becoming more popular generally, tools developed in network science keep increasing. At the same time, new types of ecological data are emerging, placing us at an opportune crossroad to reflect on when and how looking at ecological communities as networks leads to new and useful insights.
