Do seasonal dietary shifts by Temminck’s pangolins compensate for winter resource scarcity in a semi-arid environment? (2022) Panaino et al., Journal of Arid Environments, https://doi.org/10.1016/j.jaridenv.2021.104676
Climate change and habitat destruction are never positives for any species, but if that species is adaptable, they might be able to tolerate such hazards. Finding food in changing environments is one of the big challenges for a species, and there are a few things that species can do to adapt their diets when new conditions emerge. They can try and find more energy-rich food, or they could spend more time foraging to increase their energy intake (though this could also cost them more energy as well).
This is a particular problem for species which live in dry, arid environments, where food can already be scarce. In many environments vegetation and all the animal life that comes with it will often increase with temperature, but in an area that is already hot, at a certain point an increase in temperature will result in lots of vegetation dying off.
Today’s researchers selected a particularly charismatic species, the Temminck’s pangolin, and through some truly admirable fieldwork, monitored whether or not their foraging activities changed as the environment varied.

Many careers in Ecology and Evolution begin with a trip to the field. Stumbling around a rocky beach or a fragmented grassland can be an awakening experience for a young researcher, as it’s often the first time a person perceives themselves as really doing science. Field courses, and of course field work, provide opportunities to inspire the next generation of biologists. These experiences allow people to engage with nature from a scientific perspective, experiencing the challenges and joys of translating biological theory into hands-on research. Project-based field courses in particular provide an opportunity to work through the research workflow in a supportive environment, and experience what it means to put together a meaningful experiment. As such, project-based field courses have been an important and well-established element in the training of early-career researchers (ECRs) not only in Ecology and Evolution, but across all scientific disciplines, from psychology to genetics.

The first time I remember really thinking that I could be an ecologist was during a three-day trip to a field station in northern Wisconsin as part of my college limnology course. Sure, I already loved my ecology classes and learning about nature. But actually being a scientist? Real scientists, I thought, were people like my professors and graduate teaching assistants, who peppered their lectures with captivating tales of their own research.

The smartphone fallacy – when spatial data are reported at spatial scales finer than the organisms themselves (2018) Meiri, S., Frontiers of Biogeography, DOI: https://escholarship.org/uc/item/2n3349jg
One of the greatest annoyances when using museum specimens, old datasets, or large occurrence databases (such as GBIF) is when the locality of an occurrence is only vaguely described, and the coordinate uncertainty is high; “Norway” or “Indochina” doesn’t really tell you much about where that specific animal or plant was seen. Luckily, the days where such vague descriptions were the best you could get are long gone, as most of us now walk around with a GPS in our pockets, and even community science data can be reported very accurately, and more or less in real-time.
However, we have now encountered the opposite problem: the reported coordinates of organisms are often too precise to be realistic, and in the worst-case scenario, they might be borderline meaningless. The author of this study wanted to highlight how this advance in technology coupled with our eagerness to get more accurate data and results have made us too bold in our positional claims.
