Understanding the fate of shrimp aquaculture effluent in a mangrove ecosystem: aiding management for coastal conservation

Kathryn Hargan, Branwen Williams, Bunlung Nuangsaeng, Sarawut Siriwong, Pisut Tassawad, Chatdanai Chaiharn, Brian Mcadoo & Marc Los Huertos
1. Areas dedicated to shrimp aquaculture have increased dramatically over the last 50 years. Resultant land-use changes directly threaten the extent of mangroves and yield conflicts on the discharge location of aquaculture effluent. 2. Khung Krabaen Bay (KBB), Thailand, is reforesting mangroves while increasing the efficiency of shrimp aquaculture for local farmers. In this coupled shrimp farm-mangrove system, effective management requires understanding the fate of aquaculture organic matter (OM) in the coastal environment. 3. We...

Data from: Attack risk for butterflies changes with eyespot number and size

Sebastian Ho, Sandra R. Schachat, William H. Piel & Antónia Monteiro
Butterfly eyespots are known to function in predator deflection and predator intimidation, but it is still unclear what factors cause eyespots to serve one function over the other. Both functions have been demonstrated in different species that varied in eyespot size, eyespot number and wing size, leaving the contribution of each of these factors to butterfly survival unclear. Here, we study how each of these factors contributes to eyespot function by using paper butterfly models,...

From crypsis to masquerade: ontogeny changes the colour defences of a crab spider hiding as bird droppings

Long Yu, Xin Xu, Fan Li, Wei Zhou, Hua Zeng, Eunice Tan, Shichang Zhang & Daiqin Li
Selection imposed by visually-hunting predators has driven the evolution of colour-based antipredator defence strategies such as crypsis, masquerade, mimicry and aposematism. Individuals of many animals are generally considered to rely on a single type of defence strategy, but individuals of some species use multiple colour-based defences. Many animals switch between colour-based defences against visually-hunting predators during ontogeny. However, why this occurs remains poorly understood. The crab spider Phrynarachne ceylonica is an often-cited example of a...

The evolution of insect Metallothioneins

Mei Luo, Cedric Finet, Haosu Cong, Hong-Yi Wei & Henry Chung
Metallothioneins (MTs) are a family of cysteine-rich metal-binding proteins that are important in the chelating and detoxification of toxic heavy metals. Until now, the short length and the low sequence complexity of MTs has hindered the inference of robust phylogenies, hampering the study of their evolution. To address this longstanding question, we applied an iterative BLAST search pipeline that allowed us to build a unique dataset of more than 300 MT sequences in insects. By...

What’s in a band? The function of the colour and banding pattern of the Banded Swallowtail

Eunice Tan, Bodo Wilts, Brent Tan & Antonia Monteiro
Butterflies have evolved a diversity of colour patterns, but the ecological functions for most of these patterns are still poorly understood. The Banded Swallowtail butterfly, Papilio demolion demolion, is a mostly black butterfly with a greenish-blue band that traverses the wings. The function of this wing pattern remains unknown. Here, we examined the morphology of black and green-blue coloured scales, and how the colour and banding pattern affects predation risk in the wild. The protective...

Data from: Soil nutrients and dispersal limitation shape compositional variation in secondary tropical forests across multiple scales

Michiel Van Breugel, Dylan Craven, Hao Ran Lai, Mario Bailon, Benjamin L. Turner, Jefferson S. Hall & Mario Baillon
1. Soil resource partitioning and dispersal limitation have been shown to shape the tree community structure of mature tropical forests, but are poorly studied in the context of forest succession. We examined the relative contributions of both ecological processes to the variation in the species composition of young tropical secondary forests at different spatial scales, and if the relative importance of these two ecological processes changed during succession. At the species level, we examined if...

Data from: A hyperspectral image can predict tropical tree growth rates in single-species stands

T. Trevor Caughlin, Sarah J. Graves, Gregory P. Asner, Michiel Van Breugel, Jefferson S. Hall, Roberta E. Martin, Mark S. Ashton & Stephanie A. Bohlman
Remote sensing is increasingly needed to meet the critical demand for estimates of forest structure and composition at landscape to continental scales. Hyperspectral images can detect tree canopy properties, including species identity, leaf chemistry and disease. Tree growth rates are related to these measurable canopy properties but whether growth can be directly predicted from hyperspectral data remains unknown. We used a single hyperspectral image and LiDAR-derived elevation to predict growth rates for twenty tropical tree...

Data from: Accurate predictions of coexistence in natural systems require the inclusion of facilitative interactions and environmental dependency

Malyon D. Bimler, Daniel B. Stouffer, Hao Ran Lai & Margaret M. Mayfield
1. Coexistence between plant species is well known to depend on the outcomes of species interactions within an environmental context. The incorporation of environmental variation into empirical studies of coexistence are rare, however, due to the complex experiments needed to do so and the lack of feasible modelling approaches for determining how environmental factors alter specific coexistence mechanisms. 2. In this paper, we present a simple modelling framework for assessing how variation in species interactions...

Pupal brain transcriptome for Bicyclus anynana

Heidi Connahs, Eunice Tan, Yiting Ter, Emilie Dion, Ashely Bear, Yuji Matsuoka & Antonia Monteiro
Seasonal plasticity in male courtship in Bicyclus anynana butterflies is due to variation in levels of the steroid hormone 20E (20-hydroxyecdysone) during pupation. Wet season (WS) males have high levels of 20E and become active courters. Dry season (DS) males, have lower levels of 20E and reduced courtship rates, although WS courtship rates can be achieved if DS male pupae are injected with 20E at 30% of pupation. Here, we investigated the genes involved in...
