From meat to raw material: the Middle Pleistocene elephant butchery site of Casal Lumbroso (Rome, central Italy)
2025
The site of Casal Lumbroso is located in the north-west sector of Rome (central Italy). Stratigraphic and geochemical data presented here evidence that the archaeological and paleontological horizon lies at the top of the Tiber River aggradational succession related to the MIS 11c sea level highstand (dated at ca. 404 ka), and that the paleohabitat was characterised by wooded environments and humid climatic conditions. Paleontological analysis allows attributing most of the remains to an adult individual of straight-tusked elephant, Palaeoloxodon antiquus , with sporadic elements referred to Stephanorhinus sp., Bovinae, Cervinae, Cervus elaphus , Dama sp., Canis sp., Oryctolagus sp., Talpa sp., Testudines, and Amphibia. Two bird remains are referred to Anatidae and Strigiformes. A rich lithic assemblage, mainly made of flint, was also found associated with the fossil remains. Taphonomic, technological and functional analyses indicate that the P. antiquus carcass was probably exploited by humans not only as a food source, but also as a source of raw material, as documented by the presence of several intentionally fractured elephant bone fragments, some of them also with flake removals, with localized use wear traces. The findings at Casal Lumbroso highlight once again the importance of the territory around the city of Rome for Middle Pleistocene studies. The northwestern sector of the city, where other important sites such as Castel di Guido and La Polledrara di Cecanibbio have also been discovered, is therefore crucial for understanding human strategies for exploiting elephant carcasses.

Selective harvesting of large mammals: how often does it result in directional selection?
1. Harvesting of large mammals is usually not random, and directional selection has been identified as the main cause of rapid evolution. However, selective harvesting in meat and recreational hunting cultures does not automatically imply directional selection for trait size. 2. Harvesting selectivity is more than a matter of hunter preference. Selection is influenced by management regulations, hunting methods, animal trait variance, behaviour and abundance. Most studies of hunter selection only report age- or sex-specific selection, or differences in trait size selection among hunting methods or groups of hunters, rather than trait size relative to the age-specific means required for directional selection. 3. Synthesis and applications. Managers aiming to avoid rapid evolution should not only consider directional selection and trophy hunting but also mitigate other important evolutionary forces such as harvesting intensity per se, and sexual selection processes that are affected by skewed sex ratios and age structures.

Impact of Hunting on the Mammalian Fauna of Tropical Asian Forests
People have hunted mammals in tropical Asian forests for at least 40,000 yr. This period has seen one confirmed global extinction (the giant pangolin, Manis palaeojavanica) and range restrictions for several large mammals, but there is no strong evidence for unsustainable hunting pressure until the last 2000-3000 yr, when elephants, rhinoceroses, and several other species were progressively eliminated from the large parts of their ranges. Regional declines in most species have occurred largely within the last 50 yr. Recent subsistence hunting has typically focused on pigs and deer (hunted with dogs and spears or with snares), monkeys and other arboreal mammals (often caught with blowpipes), and porcupines and other rodents (smoked or dug out of burrows). Over the last 50 yr, the importance of hunting for subsistence has been increasingly outweighed by hunting for the market. The hunted biomass is dominated by the same species as before, sold mostly for local consumption, but numerous additional species are targeted for the colossal regional trade in wild animals and their parts for food, medicines, raw materials, and pets. Many populations of mammalian dispersers of large seeds and understory browsers have been depleted or eliminated, while seed predators have had a more variable fate. Most of this hunting is now illegal, but the law enforcement is generally weak. However, examples of successful enforcement show that hunting impacts can be greatly reduced where there is sufficient political will. Ending the trade in wild animals and their parts should have the highest regional conservation priority.

Road expansion and associated increases in hunting pressure are a rapidly growing threat to African tropical wildlife. In the rainforests of southern Gabon, we compared abundances of larger (> 1 kg) mammal species at varying distances from forest roads and between hunted and unhunted treatments (comparing a$130-km^2$oil concession that was almost entirely protected from hunting with nearby areas outside the concession that had moderate hunting pressure). At each of 12 study sites that were evenly divided between hunted and unhunted areas, we established standardized 1-km transects at five distances (50, 300, 600, 900, and 1200 m) from an unpaved road, and then repeatedly surveyed mammals during the 2004 dry and wet seasons. Hunting had the greatest impact on duikers (Cephalophus spp.), forest buffalo (Syncerus caffer nanus), and red river hogs (Potamochoerus porcus), which declined in abundance outside the oil concession, and lesser effects on lowland gorillas (Gorilla gorilla gorilla) and carnivores. Roads depressed abundances of duikers, sitatungas (Tragelaphus spekei gratus), and forest elephants (Loxondonta africana cyclotis), with avoidance of roads being stronger outside than inside the concession. Five monkey species showed little response to roads or hunting, whereas some rodents and pangolins increased in abundance outside the concession, possibly in response to greater forest disturbance. Our findings suggest that even moderate hunting pressure can markedly alter the structure of mammal communities in central Africa. Roads had the greatest impacts on large and small ungulates, with the magnitude of road avoidance increasing with local hunting pressure.

Hunting, Monogamy, and Economics: Are Humans Like Wolves that Hunt Elephants and Whales?
2023
Chimpanzees and bonobos are often considered the best animal models for understanding human evolutionary psychology. However, since wolves and humans evolved to cooperatively hunt animals much larger than themselves, they may provide more useful animal models. Current research on human mating and monogamy remains ambiguous, but wolf research indicates wolf monogamy facilitates imparting the skills necessary for cooperatively hunting large prey. This suggests human monogamy possibly evolved as a similar adaption for hunting large animals. The wolf-human predatory niche places no limit on the drive for large prey size except skill and cooperation. Humans have evolved hunting behaviors to the point of targeting prey as large as elephants and whales, with potential ramifications for impacting ecology.

The ongoing expansion of plantation agriculture has changed the ecological, demographic, and social conditions of Southeast Asia’s forested areas, yet little is known about hunting practices in these novel landscapes. Using information from 73 in-depth interviews with hunters, agricultural workers and wild meat dealers in the Jambi province of Sumatra, Indonesia, we describe contemporary hunting practices, including how hunting methods, wildlife harvest and consumption rates vary between different indigenous and immigrant ethnic groups. Hunting is now primarily a commercial endeavor for harvesting wild boar (Sus scrofa) meat; over 7500 wild boars were sold in Jambi City alone in 2011. The Muslim majority avoids wild boar for religious reasons, but there is substantial local and export demand driven by Chinese and Christian Batak. We conclude that hunting within oil palm plantations may reduce crop damage from wild boar and also yield large amounts of wild meat with relatively little by-catch of threatened animals.

In tropical forests, hunting nearly always accompanies logging. The entangled nature of these disturbances complicates our ability to resolve applied questions, such as whether secondary and degraded forest can sustain populations of tropical animals. With the expansion of logging in central Africa, conservation depends on knowledge of the individual and combined impacts of logging and hunting on animal populations. Our goals were (1) to decouple the effects of selective logging and hunting on densities of animal guilds, including apes, duikers, monkeys, elephant, pigs, squirrels, and large frugivorous and insectivorous birds and (2) to compare the relative importance of these disturbances to the effects of local-scale variation in forest structure and fruit abundance. In northern Republic of Congo, we surveyed animals along 30 transects positioned in forest disturbed by logging and hunting, logging alone, and neither logging nor hunting. While sampling transects twice per month for two years, we observed 47 179 animals of 19 species and eight guilds in 1154 passages (2861 km). Species densities varied by as much as 480%% among forest areas perturbed by logging and/or hunting, demonstrating the strong effects of these disturbances on populations of some species. Densities of animal guilds varied more strongly with disturbance type than with variation in forest structure, canopy cover, and fruit abundance. Independently, logging and hunting decreased density of some guilds and increased density of others: densities varied from 44%% lower (pigs) to 90%% higher (insectivorous birds) between logged and unlogged forest and from 61%% lower (apes) to 77%% higher (frugivorous birds) between hunted and unhunted forest. Their combined impacts exacerbated decreases in populations of some guilds (ape, duiker, monkey, and pig), but counteracted one another for others (squirrels, insectivorous and frugivorous birds). Together, logging and hunting shifted the relative abundance of the animal community away from large mammals toward squirrels and birds. Logged forest, even in the absence of hunting, does not maintain similar densities as unlogged forest for most animal guilds. To balance conservation with the need for economic development and wild meat in tropical countries, landscapes should be spatially managed to include protected areas, community hunting zones, and production forest.
