Abstract

Current climate change is disrupting biotic interactions and eroding biodiversity worldwide. However, species sensitive to aridity, high temperatures, and climate variability might find shelter in microclimatic refuges, such as leaf rolls built by arthropods. To explore how the importance of leaf shelters for terrestrial arthropods changes with latitude, elevation, and climate, we conducted a distributed experiment comparing arthropods in leaf rolls versus control leaves across 52 sites along an 11,790 km latitudinal gradient. We then probed the impact of short- versus long-term climatic impacts on roll use, by comparing the relative impact of conditions during the experiment versus average, baseline conditions at the site. Leaf shelters supported larger organisms and higher arthropod biomass and species diversity than non-rolled control leaves. However, the magnitude of the leaf rolls' effect differed between long- and short-term climate conditions, metrics (species richness, biomass, and body size), and trophic groups (predators vs. herbivores). The effect of leaf rolls on predator richness was influenced only by baseline climate, increasing in magnitude in regions experiencing increased long-term aridity, regardless of latitude, elevation, and weather during the experiment. This suggests that shelter use by predators may be innate, and thus, driven by natural selection. In contrast, the effect of leaf rolls on predator biomass and predator body size decreased with increasing temperature, and increased with increasing precipitation, respectively, during the experiment. The magnitude of shelter usage by herbivores increased with the abundance of predators and decreased with increasing temperature during the experiment. Taken together, these results highlight that leaf roll use may have both proximal and ultimate causes. Projected increases in climate variability and aridity are, therefore, likely to increase the importance of biotic refugia in mitigating the effect

Abstract

The construction of shelters on plants by arthropods might influence other organisms via changes in colonization, community richness, species composition, and functionality. Arthropods, including beetles, caterpillars, sawflies, spiders, and wasps often interact with host plants via the construction of shelters, building a variety of structures such as leaf ties, tents, rolls, and bags; leaf and stem galls, and hollowed out stems. Such constructs might have both an adaptive value in terms of protection (i.e., serve as shelters) but may also exert a strong influence on terrestrial community diversity in the engineered and neighboring hosts via colonization by secondary occupants. Although different traits of the host plant (e.g., physical, chemical, and architectural features) may affect the potential for ecosystem engineering by insects, such effects have been, to a certain degree, overlooked. Further analyses of how plant traits affect the occurrence of shelters may therefore enrich our understanding of the organizing principles of plant-based communities. This data set includes more than 1000 unique records of ecosystem engineering by arthropods, in the form of structures built on plants. All records have been published in the literature, and span both natural structures (91% of the records) and structures artificially created by researchers (9% of the records). The data were gathered between 1932 and 2021, across more than 50 countries and several ecosystems, ranging from polar to tropical zones. In addition to data on host plants and engineers, we aggregated data on the type of constructs and the identity of inquilines using these structures. This data set highlights the importance of these subtle structures for the organization of terrestrial arthropod communities, enabling hypotheses testing in ecological studies addressing ecosystem engineering and facilitation mediated by constructs.

Abstract

The article focuses on Challenges and Opportunities in the Study of Snake Diets. Topics discussed include the importance of feeding in the evolution and ecology of snakes is difficult to overstate; and feeding and diet have had profound influences on phylogenetic diversification (Greene 1983), promoted morphological and behavioral diversification (Greene and Burghardt 1978; Hoso et al. 2007; Glaudas and Alexander 2017), and have driven the evolution of extreme physiology.

15. HOW MANY HARLEQUINS? MORPHOLOGICAL, MOLECULAR, AND ECOLOGICAL EVIDENCE FOR CRYPTIC DIVERSITY WITHIN THE AFRICAN LAMPROPHIID HOMOROSELAPS LACTEUS.

Abstract

Homoroselaps lacteus (Linnaeus, 1758) is a species of polymorphic, ornately-coloured lamprophiid snakes from southern Africa. Herpetologists have long recognised that the three colour morphs are largely geographically predictable, with barred individuals occurring in the south-western Cape, blotched individuals occurring in the Eastern Cape Province, and striped individuals occurring across the north eastern parts of the geographic distribution. Several workers have speculated that the colour patterns represent different species--an idea corroborated by a recent publication that showed significant genetic divergence between a small number of samples. Here we draw on meristic data from the examination of 148 specimens, geo-referenced digital images of 131 animals, phylogenetic maximum likelihood analysis of molecular sequence data (16S, cyt-b, RAG-1) from 23 individuals, and species distribution modelling approaches to examine the evidence for species-level differentiation within the group. Additionally, we present a thorough summary of the diet of H. lacteus as revealed by examination of museum specimen gut contents and observations drawn from a social media platform used to gather dietary data for southern African herpetofauna. Our results reveal that, in general, the three colour morphs occupy three parapatric geographical ranges which correspond broadly with three well resolved phylogenetic clades. However, not all specimens could be unambiguously assigned to one of the three colour patterns or phylogenetic clades suggesting additional evolutionary complexity within the clade. Our meristic data revealed a subtle increase in the number of ventral scales and subcaudal scales of the barred colour morph relative to the two other forms, however our dietary data suggested that diet is largely conserved across the clade, being restricted to the consumption of elongate squamate reptiles. We conclude by discussing the implications of our findings for the systematics of H. lacteus, and highlight the value of integration of morphological, molecular, and ecological data in understanding the evolutionary origins of snakes.

16. A METHOD FOR REMOTELY MEASURING ACTIVITY PATTERNS IN FREE-RANGING SNAKES.

Abstract

The secretive nature of snakes makes their behaviour and activity patterns difficult to study in a natural setting. This is especially true for alert, actively foraging snakes such as Cape Cobras, whose vigilance while foraging can easily result in significant observer effects. Additionally, Cape Cobras may spend a major portion of each day underground, making traditional focal animal analysis an extremely inefficient method for collecting information on their activity. Over recent years, biologging has become more important in the study of free-ranging animals. Custom built bio-logging devices attached to, or implanted into, large highly mobile and active mammals have proved to be very successful in collecting data on a range of physiological and behavioural traits. However, this has been less successful for small, less active animals such as snakes. We used implanted iButtons to record body temperature (Tb) of telemetered free-ranging Cape Cobras in the Kalahari Desert, South Africa. We inferred the behaviour (e.g., inactive underground; active above ground; basking etc.) of snakes from the resulting Tb profiles. We then compared our inferences of Tb profiles to field observations in a ground truthing exercise to verify the accuracy of our interpretations. Tb profiles revealed distinctive patterns that, when compared to environmental temperatures (Te), allowed us to score behaviour remotely. This made it possible to assess activity periods in relation to time of day, season and Te. We concluded from the thermal profiles that if active, the cobras display a daily bimodal activity pattern in summer, and occasionally forage at night. During the hot months of the year, the snakes spend a large proportion of their active time foraging and less time basking. The snakes usually limit surface activity to the mornings and evenings as they avoid the hottest hours of the day. In the winter months, however, the snakes may come out more frequently and regularly but if active they stay on the surface during the warmest hours in the middle of the day. While foraging behaviour occurs less in winter the snakes bask frequently close to their shelter and tend to stay on the surface for longer periods than in summer. This method opens the path to assess and analyse the thermal ecology of free-ranging animals without human disturbance. [ABSTRACT FROM AUTHOR]

17. USING FAECAL DNA TO INVESTIGATE THE DIETS OF THE SNAKES PSAMMOPHIS CRUCIFER AND PSAMMOPHYLAX RHOMBEATUS.

Abstract

Conventional approaches to studying snake diets rely upon visual identification of prey items obtained either via palpation of meals from live snakes, examination of faecal remains, or from gut contents of preserved specimens. These approaches can be biased, invasive, and often do not depict the full dietary breadth of a species. Molecular approaches provide novel mechanisms for gathering information that allows us to increase our knowledge and understanding of a predator's prey intake. Here, we propose a project that demonstrates the use of molecular analysis of snake faeces to study the diet of Psammophis crucifer and Psammophylax rhombeatus. We intend to use PCR analysis in conjunction with DNA cloning techniques to identify prey items of known identity from faecal samples of captive snakes thereby testing the hypothesis that molecular techniques can be used to identify, to species level, the remains of prey items in the faeces of these two species of snakes. Should our approach be successful, researchers would be able to sample snake diets at the population level with high intensity, including resampling individual snakes, all in a relatively non-invasive manner.

18. SHARING FOR SCIENCE: USING SOCIAL MEDIA TO BETTER UNDERSTAND THE DIETS OF AFRICAN SNAKES.

Abstract

An incomplete understanding of the feeding ecology of organisms impedes our ability to address questions related to energy flow within an ecosystem, predatorprey dynamics, population dynamics, niche partitioning, habitat preference, and the evolution of behaviours and traits. For most African snake species, it is difficult to study feeding ecology due to low detectability of study organisms and an even lower incidence of in situ feeding observations. Moreover, the cost and time associated with extensive field sampling are often prohibitive and sampling often involves destructive methods. In our study, we harnessed the power of Facebook as a crowdsourcing platform, which is comprised of thousands of potential observers, to collect photographic records of predation events involving reptiles and amphibians in sub-Saharan Africa. Feeding events in snakes were particularly well-represented with nearly 1,000 feeding events recorded in the last four years. To evaluate the usefulness of this method, we compared the observations collected from Facebook to observations we recorded from an extensive literature review on the diets of wild southern African snakes (~3,200 feeding observations). An analysis of the two datasets revealed how effectively and rapidly information on these difficult to detect ecological interactions can be collected at broad spatial, temporal, and taxonomic scales. Our work highlights that our understanding of snake feeding ecology is far from complete and that multiple methods should be utilised to compile a comprehensive and robust dataset.
