Tropical field stations yield high conservation return on investment

Dr. Tim Eppley led a recent study titled “Tropical field stations yield high conservation return on investment” that was published in Conservation Letters. The study consisted of a survey of field stations in mostly tropical and subtropical countries, to understand the impact of the pandemic on funding and evaluate the conservation benefits of the field stations.

Towards new agricultural practices to mitigate food insecurity in southern Madagascar

Dr. Tim Eppley and colleagues published this chapter in the book Defining Agroecology: A Festschrift for Teja Tscharntke. The volume was compiled in honor of Prof. Tscharntke, whose legacy is synonymous with agroecology. In the study, Dr. Eppley et al. evaluated agricultural practices in southern Madagascar, a food-insecure region that suffers from droughts and exponential human population growth. They found that food insecurity could be improved if annual crops were replaced or combined with perennial crops in agroforestry systems. This benefits humans while protecting remaining forest habitats for native plants and animals.

Evaluating the impact of infrastructure and human-modified landscapes on spatial patterns of primate species

Dr. Tim Eppley and colleagues recently published an article in the high-profile journal Global Change Biology, evaluating the impact of infrastructure and human-modified landscapes on spatial patterns of primate species worldwide. They show that the negative impact of anthropogenic pressures is leading to a significant decline in global primate biodiversity. They advocate for stronger national and international policies that promote sustainable livelihoods and reduce pressures.

Huddling is more important than rest site selection for thermoregulation in southern bamboo lemurs

Resting site selection can have important effects on the behavior and fitness of organisms. We sought to determine whether a medium-sized lemur model, the southern bamboo lemur (Hapalemur meridionalis), would maintain thermoregulation through microhabitat rest site selection, huddling behavior, or potentially both strategies.

Evidence of spatiotemporal planning in a panther chameleon (Furcifer pardalis) on the Masoala Peninsula, Madagascar

There is a generally a lack of information on the natural history and reproduction of the panther chameleon (Furcifer pardalis) in the wild, and few written accounts of egg deposition. Here, I report an unusual behavior of nesting and egg deposition in a panther chameleon, based on observations made at a field site in northeastern Madagascar.

Factors influencing terrestriality in primates of the Americas and Madagascar

Primates from the Americas and Madagascar are predominantly arboreal but occasionally descend to the ground. As anthropogenic impacts to habitats and climate worsen, our results suggest that diurnal species already inhabiting hot, sparsely canopied sites, and exhibiting more generalized diets, are more likely to shift toward greater ground use.

A habitat stronghold on the precipice: A call‐to‐action for supporting lemur conservation in northeast Madagascar

The northeast of Madagascar is as diverse as it is threatened. The area bordering the Analanjirofo and SAVA regions contains six protected areas and at least 22 lemur species. In this paper, we discuss the major threats to the region and advocate for eight conservation activities that help reduce threats and protect the environment.

Do functional traits offset the effects of fragmentation? The case of large‐bodied diurnal lemur species

Primates worldwide are faced with increasing threats, particularly anthropogenic disturbances, making them more vulnerable to extinction. As this situation continues to worsen, we sought to understand how fragmentation affects primate distribution throughout the island, and to estimate the role of functional traits in mitigating their response.

Urgent action needed: the forgotten forests of the Lavasoa-Ambatotsirongorongo Mountains, southeast Madagascar

When people think of important areas of biodiversity within Madagascar, they tend to focus on the more well-known national parks and special reserves. The truth is, though, that there are many small fragments of habitat scattered across the island that hold a significant wealth of biodiversity and are in critical need of attention and immediate conservation actions.
