Camel livestock is an ancestral activity in Algeria; however, climate change has forced camel herders to modify their breeding practices make them more sustainable. This study summarized production practices, milk qualities, and the potential of preserve ability under global warming. To collect data related farming 10 were interviewed using a formal questionnaire. Then, 15 samples (9 raw 6 that had undergone heat treatment) collected region Oued Souf southeastern Algeria carry out...
In the Mediterranean, Urothemis edwardsii is one of most threatened dragonfly species with a relict population restricted to northeast Algeria.Despite recent subtle local expansion in geographic distribution during past decade, studies on life history are still lacking.We carried out study phenology emergence and flight season Lake Bleu, Northeast-Algeria.Using repeated sampling exuviae marking adults two seasons (2018 2019), we estimated size, sex ratio, temporal pattern season.The first...
Capsule: Collective roosting behaviour of the Cattle Egret Bubulcus ibis was influenced by weather and season.Aims: To document assess relationship between conditions four components including population size, duration roost occupancy, timing gathering rate arrival at roost.Methods: We recorded number times individuals occupying a communal site in northeast Algeria 2013–2014 December April.Results: There seasonal decline flock size increase gathering. Weather affected all variables assessed...
Summary.Assessing temporal changes of the distribution threatened species is paramount for effective management. Threatened are sensitive to environmental and can be extirpated rapidly due climatic anthropogenic effects. Here, we monitor locally critically endangered Urothemis edwardsii in northeastern Algeria where has been recovering during last decade after being restricted a single locality since 1990s. During flight seasons 2018, 2019, 2021, conducted field surveys recording number...
Age is a critical intrinsic factor that influences the probability of survival organisms on Earth. In many animals, lifestyles and habitat occupancy males females are so different effect age could be sex-dependent. To reveal such patterns in wild animal populations, we here use natural population Mediterranean demoiselle Calopteryx haemorrhoidalis Vander Linden (Calopterygidae: Zygoptera) Northeast Algeria to analyze influence sex using daily capture–mark–recapture. We used stepwise model...
Understanding habitat requirements of species conservation concern is central for their and management. Although much the research attention has been focused on reproductive sites, understanding roosting behavior microhabitat selection, potential fitness consequences also crucial. Here, we assess an endangered endemic damselfly Calopteryx exul Selys in a lotic Northeast Algeria. Based marked individuals, specifically investigated vertical horizontal distribution at as well timing its...
Abstract The white-headed duck is a globally threatened species and its populations have become fragmented undergone major decline in recent decades. Changes including long-term abundance (five times from 2005 to 2018) diurnal activity budget (2010−2011 2017−2018) with respect the effect of habitat features at Boussedra marsh (unprotected area) were compiled order fill some gaps status trend North African populations. population size decreased over years 2010 2018 by about 52.81%, was...
Abstract Decreased ambient temperature and shorter reproductive seasons are the two main obstacles that ectotherms face at higher elevations. Studies have shown some life history traits such as phenological windows of activity, duration, fitness components vary elevation increases. However, studies on elevational gradient southern range limit species lacking. In this study, we aim assessing aspects a spider species, sprassid Micrommata ligurina (C.L. Koch, 1845), across an from 30 to 1030 m...
Atmospheric conditions play an important role in structuring avian communities space and time. Here we assess the of weather on distribution abundance enigmatic glossy ibis (Plegadis falcinellus) Northeast Algeria both wintering grounds breeding areas a survey spanning from 2011 to 2019. During study period, cooler years were wetter warmer drier. The population size region could be estimated 200-300 individuals. number individuals increased recent one site (Berrihane), but it did not show...
Ectotherms respond quickly to environmental change and thus are prone show adaptive mechanisms across a gradient of conditions. Frogs in particular have been widely used experimental ecology test life history theory plasticity gradients. However, little has carried out on the North African Sahara frog (Pelophylax saharicus) which experiences particularly stressful environment characterized by warm dry In this study, we documented adaptation P. saharicus elevation northeast Algeria using six...
Abstract Species adjust their behavior and life-history to adapt local environmental conditions. with large ecological prevalence often show signatures of adaptations different environment, particularly in extreme ones. Here, we investigate adaptation populations the North African Sahara frog ( Pelophylax saharicus ) living various conditions that varies mostly temperature, precipitation, elevation by mean common garden experiment aiming estimate growth rate under two predation treatments...
