“…This result confirmed the high sleeping site fidelity suggested by Meier and Albignac [1991]. C. major and C. medius also had high tree hole fidelity [Müller, 1999a, b;Lahann, 2007]. C. major family groups repeatedly used 1 or 2 group-exclusive tree holes, while C. medius family groups re-used their tree holes from 1 year to the next.…”

“…Four species use leaf nests exclusively (Microcebus griseorufus , Microcebus myoxinus , Mirza coquereli and Mirza zaza) [Kappeler, 1998;Kappeler et al, 2005;Génin, 2008]. Tree holes are used exclusively or in combination with leaf nests by the majority of species (Cheirogaleus major , Cheirogaleus medius , Microcebus berthae , Microcebus murinus , Microcebus ravelobensis , Microcebus rufus and Phaner pallescens) [Martin, 1973;Wright and Martin, 1995;Radespiel, 1998;Schmid, 1998;Müller, 1999a;Schmelting, 2000;Schwab, 2000;Fietz and Dausmann, 2003;Radespiel et al, 2003;Schülke and Kappeler, 2003;Dammhahn and Kappeler, 2005;Dausmann et al, 2005;Rasoazanabary, 2006;Lahann, 2007Lahann, , 2008; Deppe et al, 2008]. Although the hairy-eared dwarf lemur (Allocebus trichotis) has previously been observed to use tree holes and the characteristics of a few of these cavities have been reported, it is important for the survival of this enigmatic species to gather additional information on this aspect of its habitat needs [Meier and Albignac, 1991;Rakotoarison et al, 1997;Goodman and Raselimanana, 2002].…”

“…Although studied in a different area, the sympatric M. rufus was reported to use leaf nests at 1-10 m above ground as well as tree holes; while the sympatric C. major was observed to build leaf nests at 12-20 m height and to use tree holes at 8-10 m height in trees with diameters over 47 cm [Wright and Martin, 1995;Lahann, 2007;Deppe et al, 2008].

“…In the Cheiro-galeidae, the social system is usually either a dispersed multi-male/multi-female group (M. berthae , M. ravelobensis , M. rufus and M. zaza) or a dispersed or gregarious family group composed of an adult pair with or without offspring (Cheirogaleus spp. and P. pallescens) [Charles-Dominique and Petter, 1980;Atsalis, 1998Atsalis, , 2000Müller, 1998Müller, , 1999aFietz, 1999Fietz, , 2003Schwab, 2000;Schülke, 2002;Radespiel et al, 2003;Schülke and Kappeler, 2003;Weidt et al, 2004;Braune et al, 2005;Dammhahn and Kappeler, 2005;Kappeler et al, 2005;Lahann, 2007Lahann, , 2008. Male or female uni-sex pairs (M. griseorufus) , female groups with solitary males (M. murinus) or solitary females with offspring and solitary males (M. coquereli) have also been observed [Martin, 1973;Pagès, 1978;Kappeler, 1997a, b;Radespiel, 1998Radespiel, , 2000Schmelting, 2000;Schwab, 2000;Eberle and Kappeler, 2002;Wimmer et al, 2002;Radespiel et al, 2003;Génin, 2008;Lahann, 2008].…”

In this study we describe tree hole characteristics and use by the hairy-eared dwarf lemur (Allocebus trichotis) to determine habitat needs, potential functions of tree holes and sleeping group composition. We radio-tracked 6 adult individuals between April and November 2007 in the Analamazaotra Special Reserve. Tree holes were 1–9 m high (median: 7 m), in living trees measuring 26–54 cm in diameter at breast height (median: 32 cm), and could be a limiting resource. Each individual used 4 or 5 tree holes and had high nest fidelity. Animals most often slept socially in mixed-sex groups of 2–6 individuals and occasionally shared a tree hole with white-tailed tree rats (Brachytarsomys albicauda). We identified two sleeping groups: one composed of 2 adult males, 2 adult females and 2 juveniles; one composed of at least 2 adult females and 2 juveniles. Although tree holes were generally group exclusive, some intergroup sleeping was observed. Tree holes could have antipredator and thermoregulatory functions. Further research into sleeping hole availability, nest use and the degree of niche separation or competition between sympatric Cheirogaleidae and other tree hole users (e.g. endemic rodents) is needed to assess better the conservation needs of these species.

“…Requirements for and usage of sleeping sites may vary for nocturnal primates based on body size, social structure, and need for thermal insulation [e.g., Schmid, 1998;Bearder et al, 2003;Lahann, 2007Lahann, , 2008Lutermann et al, 2010;Dausmann, 2013]. A common factor influencing whether a hole can serve as a potential sleeping site is tree DBH [Gursky, 1998;Hankerson et al, 2007;Seiler et al, 2013a].…”

Knowledge of the key resources for a species is critical for developing an effective conservation strategy. Kirindy Mitea National Park is an important refuge for the red-tailed sportive lemur (Lepilemur ruficaudatus), a nocturnal folivorous lemur endemic to the dry deciduous forest of western Madagascar. Because L. ruficaudatus sleeps in tree holes during the day, sleeping trees may be an important resource for this species. Our goal was to characterize the sleeping sites used by L. ruficaudatus at the Ankoatsifaka Research Station in Kirindy Mitea National Park. In July and August 2012, tree characteristics were recorded for 60 L. ruficaudatus sleeping sites. Intact and alive trees, particularly Strychnos madagascariensis, were preferred by L. ruficaudatus. Sleeping holes were generally located in taller trees (median hole height = 4 m) and in trees with large girths (median = 20.5 cm). Greater protection from predators and thermal shifts may be provided by intact trees and concealed tree holes. Because tree characteristics can influence the presence and abundance of forest-living primates, the availability and characteristics of particular trees as potential sleeping shelters in a habitat must be taken into account in conservation strategies for L. ruficaudatus.

Forest loss and degradation due to land cover changes imperil biodiversity worldwide. Subtropical and tropical ecosystems experience high deforestation rates, negatively affecting species like primates. Madagascar's endemic lemurs face exceptionally high risks of population declines and extirpation. We examined how short‐term land cover changes within a fragmented landscape in southeastern Madagascar impacted the density of lemur species. Using line transects, we assessed density changes in nine lemur species across five forest fragments. Diurnal surveys were conducted monthly from 2015 to 2019 on 35 transects (total effort = 1268 km). Additionally, 21 transects were surveyed nocturnally in 2015 and 2016 (total effort = 107.5 km). To quantify forest cover changes, we generated land use/land cover (LULC) maps from Sentinel‐2 imagery using supervised classification for each year. For the LULC maps, we overlayed species‐specific buffers around all transects and calculated the proportion of land cover classes within them. We observed declines in the annual densities of four diurnal and cathemeral lemur species between 2015 and 2019, with species‐specific declines of up to 80% (Varecia variegata). While the density of two nocturnal species decreased, one increased fivefold (Cheirogaleus major) between 2015 and 2016. By 2019, Grassland was the dominant land type (50%), while Paddy Fields had the smallest coverage (1.03%). Mature Agricultural Land increased the most (63.37%), while New Agricultural Land decreased the most (–66.36%). Unexpectedly, we did not find evidence that higher forest cover supported a higher lemur population density within sampled areas, but we found support for the negative impact of degraded land cover types on three lemur species. Our study underscores the urgent need to address land‐use changes and their repercussions for primate populations in tropical ecosystems. The diverse responses of lemur species to modified habitats highlight the complexity of these impacts and emphasize the importance of targeted conservation efforts.
