“…The site was targeted for the survey as the insect diversity of the area was previously known to be high. Initial identifications revealed 73 families of Diptera and an estimate of over 4300 species, including 286 of Tachinidae (Brown et al ., ).…”

Insect parasitoids may be an exception to the typical biogeographic pattern of increasing species richness at lower latitudes exhibited by most taxa. Evidence for this ‘anomalous’ latitudinal gradient has been derived from observations of hymenopteran parasitoids and it has been argued that other parasitoid groups should show a similar pattern of diversity. Several mechanisms have been proposed to explain this disparity, most notably the nasty host and resource fragmentation hypotheses. We review and evaluate these hypotheses with respect to tachinid flies (Diptera: Tachinidae), and bring to the argument evidence from eight trapping surveys from temperate and tropical regions in the Americas including the United States, Costa Rica, and Ecuador. We find no evidence that tachinid fly diversity is lower in the tropics than in the temperate region. Our results, along with other lines of evidence, rather suggest that New World Tachinidae likely conform to the same negative relationship between latitude and richness as their largely phytophagous host taxa. We discuss geographic patterns of tachinid diversity in relation to ecological and evolutionary processes, and why they may differ from their hymenopteran parasitoid counterparts. Parasitoid taxa appear to vary strongly in their diversity responses to latitude and we concur with previous researchers that more survey data are necessary to reach strong conclusions about parasitoid latitudinal diversity patterns.

“…This is a particular problem in tropical regions, where there is a substantial need for data. Alternative data gathering exercises, namely intensive local sampling areas (i.e., Bouchet, Lozouet, Maestrati & Heros, ; Brown et al., ; Longino et al., ) could also be useful, but these sampling endeavors also require extremely high levels of expertise and investment, which are often unavailable, and are not practical on a regional scale. In these cases, museum and other historical natural history collections provide a useful resource for estimating regional species richness.…”

Quantifying regional biodiversity in the tropics: A case study of freshwater fish in Trinidad and Tobago

et al. 2019

Extinction rates are predicted to accelerate during the Anthropocene. Quantifying and mitigating these extinctions demands robust data on distributions of species and the diversity of taxa in regional biotas. However, many assemblages, particularly those in the tropics, are poorly characterized. Targeted surveys and historical museum collections are increasingly being used to meet the urgent need for accurate information, but the extent to which these contrasting data sources support meaningful inferences about biodiversity change in regional assemblages remains unclear.Here, we seek to elucidate uncertainty surrounding regional biodiversity estimates by evaluating the performance of these alternative methods in estimating the species richness and assemblage composition of the freshwater fish of Trinidad & Tobago.We compared estimates of regional species richness derived from two freshwater fish datasets: a targeted two year survey of Trinidad & Tobago rivers and historical museum collection records submitted to The University of the West Indies Zoology Museum. Richness was estimated using rarefaction and extrapolation, and assemblage composition was benchmarked against a recent literature review. Both datasets provided similar estimates of regional freshwater fish species richness (50 and 46 species, respectively), with a large overlap (85%) in species identities. Regional species richness estimates based on survey and museum data are thus comparable, and consistent in the species they include. Our results suggest that museum collection data are a viable option for setting reliable baselines in many tropical systems, thereby widening options for meaningful monitoring and evaluation of temporal trends.Abstract in Spanish is available with online material.

In proposing what might be the three leading questions in taxonomy, I have thought primarily about what might be the biggest barriers to taxonomists accurately describing the species on our planet and interpreting their phylogenetic relationships within a historical context. I have generally used the vernacular and examples of issues which I know as a dipterist (fly taxonomist). I apologize to my colleagues working on other groups but hope to be pardoned in the recognition that the problems identified below do appear to apply to our broader taxonomic community. 1. What are the impacts of the rapid rate of present day extinctions? 2. What is the future for taxonomists themselves? 3. What are some of the impacts of technology?
