Honey Possum

ANIMALS are commonly separated into two major categories based on their activity patterns: diurnal and nocturnal. However, evidence of numerous species exhibiting diverse periods of activity, including arhythmic and crepuscular habits, broadens the description. The honey possum (Tarsipes rostratus), a small West-Australian marsupial feeding exclusively on nectar and pollen, has been described as strongly nocturnal (Wooller et al. 1981; Russell and Renfree 1989). However, infrequent daytime activity in captivity (Russell 1986) and in the wild under cold, cloudy conditions, has been reported (Hopper and Burbidge 1982; du Plessis and du Plessis 1995). During trapping exercises in the region of Jurien Bay (250 km north of Perth, Western Australia), several animals were observed foraging after sunrise and before sunset, with occasional diurnal activity. To date, no study has investigated directly the activity periods of the species. Furthermore, studies of the visual capabilities of T. rostratus revealed that its retinal organisation is not compatible with a nocturnal lifestyle, but presents features comparable to those found in diurnal species (Arrese 2002; Arrese et al. 2002). Such discrepancies warranted the monitoring of activity periods (rhythmicity) of T. rostratus in its natural environment, a study reported here. We discuss our results in the context of the visual ecology of the species.

Several Pterygoplichthys species, members of the Neotropical catfish family Loricariidae, have been widely introduced outside their native ranges. In this paper, I present observations on the diel activity pattern of non-native Pterygoplichthys, tentatively identified as P. disjunctivus, with respect to their attachment and grazing on endangered Florida manatees, Trichechus manatus latirostris. The study was conducted in December 2009 at Volusia Blue Spring, an artesianal spring system in the St. Johns River basin, Florida (USA). Supplemented by information gathered during previous visits to the spring site, this study revealed that adult Pterygoplichthys are active throughout the diel period (day, twilight and night). However, juvenile Pterygoplichthys were largely nocturnal and only at night did they consistently join adults in attaching to manatees. The juveniles generally remain hidden during the day, probably responding to presence of diurnal predators, mainly birds. Differences in diel behaviors among different Pterygoplichthys size classes in Florida are consistent with published observations on loricariids inhabiting clearwater streams within their native ranges.

Present research was planned to evaluate the breeding and feeding behaviour of Indian peafowl reared in captivity at Zoological Gardens of Government and Private Sector. For feeding behaviour, a total of fifty pairs (n=100) of Pavo cristatus at both Government Zoological Gardens (n=25pairs) and Private Sectors (n=25pairs) were observed on daily basis. The breeding season of Indian peafowl is not fixed but mostly it breeds in rainy season from April to August. It was observed that most of birds at Government Zoological Gardens breed in month of May, while most of birds at Private Sectors breed in the month of August. For feeding behaviour a total of 200 faecal samples per week were collected for six weeks, out of which 100 samples per week were randomly selected for further analysis. Faecal analysis technique showed that dietary components of Indian peafowl were covered by plant contents following by animal sources. Among the plants components grass seeds were predominant followed by dicotyledon and fruits with least portion of monocotyledons. Among animal components, ants, grasshopper, earthworms, spider and unidentified bones were present. Faecal analysis indicated the presence of some non-food items such as sand and gravel.

'In a colony of captive koalas, all aggressive behaviour was a variation on the single motor pattern of throwing a foreleg around an opponent and biting. Squabbles (the most common aggressive behaviour) were brief, low level interactions usually arising from the efforts of one koala to climb past or over another. Minor fghts involved only single bites and the combatants stayed in the same place; major ,fights involved multiple bites and changes of position. Dependent young were seldom involved in aggression. Between males. minor fights were essentially intensified squabbles, but major fights involved wrestling and chasing; they were more likely between males unfamiliar with each other, or those already aroused by, e.g., other aggressive interactions. Females became aggressive especially during pregnancy and at the end of lactation. At such times they stood their ground and vocalized at other koalas, especially males, but attacked only if the opponent came within reach. Although the opponent usually withdrew. sometimes a male seemed provoked to attack. Males sometimes attacked females without obvious provocation. Aggression was slightly more common in than outside the breeding season. Competition for females or food, dominance hierarchies, appeasement, and the defence of young were not seen.

The author examines the age structure of captive orang-utans in zoos and institutions. He shows that, unless breeding success can be achieved with captive-born animals – which so far no zoo in the world has done – zoo numbers will continue to decline, with little hope of replacement from the wild now that the International Convention on Trade in Endangered Species is in operation. John Perry is Assistant Director for Conservation at the National Zoo in Washington, and a Vice-Chairman of the IUCN's Survival Service Commission.

An entomological prospection to show the species composition and diurnal activity of tabanids was carried out using 15 Vavoua traps, during the rainy season (25th Sept-5th Oct and 21st Oct-9th Nov 2018), in the secondary forest [Ivindo National Park (INP)] and Village-Town sites in and around the biosphere reserve Ipassa-IRET Makokou in Gabon. In total, 839 tabanids were caught with 747 recorded at INP and regrouped under 11 species of the genus Tabanus [T. taeniola (57.76%),               T. ricardae (26.32%), T. par (5.54%), T. ruficrus (3.74%), T. socius (3.74%), T. disjunctus (2.49%), T. marmorosus (0.28%) and T. obscurehirtus (0.14%)]. However, two species of the genus Chrysops [C. dimidiatus (70.83%) and C. silaceus (29.17%)] and one species of the genus Haematopota [H. pluvialis (100%)] were only identified at INP. While in the Village-Town sites, 92 tabanids were caught and regrouped under five species of the genus Tabanus [T. ruficrus (14.13%), T. taeniola (9.78%), T. ricardae (73.91%), T. par (1.09%), and T. marmorosus (1.09%)]. Tabanids were more abundant in the forest (7.12 tabanid/trap/day) as compared to the Village-Town (0.77 t/t/d) with a statistically significant difference (P<0.05). At INP, tabanids showed a unimodal activity pattern with peak attained between 12-14H and in the anthropized milieu (14-16H) and dominated by females.

Courtship Activity

Freshwater crocodiles were maintained in captivity, and during the 1978 breeding season the reproductive behaviour of two pairs was observed. During 23 days, 14 courtships were recorded. Typical courtship activity is described. Nesting activities always occurred between sundown and 2130 h. During incubation females visited their respective nests regularly but did not appear to be protective. The growth rate of developing embryos is described and nest opening by the female recorded.
