A possible case of lek demes in some troglophilic bats and interspecific relations in bat colonies from some Romanian caves?

open access: yesTravaux de l'Institut de Speologie Emile Racovitza, 2018
Five bat species from the Romanian fauna shelterand hibernate in caves: Mediterranean Horseshoe Bat – Rhinolophus euryale Blasius, 1853; Mehely’s horseshoe bat – Rhinolophus mehelyi Matschie, 1901; the common bent-wing bat/Schreibers’ long-fingered bat ...

Individual Variation in Overwintering Strategies of the Great Evening Bat (Ia io) in Subtropical China 中国亚热带地区大足蝠 (Ia io) 越冬策略的个体差异

open access: yesWildlife Letters, EarlyView.
Tracking with GPS and accelerometers shows that great evening bats in subtropical China use two overwintering strategies: some remain in continuous hibernation, while others switch between torpor and activity as temperatures change. This behavioral flexibility, shaped by climate, underscores the importance of protecting diverse roosting habitats for ...

Modified wintering strategy in Daubenton’s bat (Myotis daubentonii, Kuhl 1817) in response to climate change, a case study in “Nietoperek” bat reserve (W. Poland)

open access: yesThe European Zoological Journal
Climate change is impacting on wildlife. Animals that hibernate, such as bats (Chiroptera), are particularly susceptible to the adverse effects of shortened winters, reduced snow cover, weather anomalies and increased underground temperatures. To measure

Comparing the performance of object and object relational database systems on objects of varying complexity [PDF]

open access: yes, 2012
This is the first published work to compare the performance of object and object relational database systems based on the object's complexity. The findings of this research show that the performance of object and object relational database systems are ...

Torpor‐assisted migration: Regular use of shallow torpor reduces rest‐phase energy expenditure for songbirds during migration

open access: yesJournal of Animal Ecology, EarlyView.
Migrating songbirds regularly use shallow torpor (up to 98% of birds for some species) to save energy (up to 42%) during inactive periods. This Ruby‐crowned Kinglet Corthylio calendula that was captured after a spring snowstorm highlights the value of being able to save energy when encountering unfavourable conditions.

Exposing the myth: object-relational impedance mismatch is a wicked problem [PDF]

open access: yes, 2015
Addressing a problem of software integration is a fact of life for those involved in software development. The popularity of both object and relational technologies means that they will inevitably be used together.

Season and human footprint weaken the negative effect of temperature on the intraspecific metabolic scaling exponent of wild brown trout populations

open access: yesJournal of Animal Ecology, EarlyView.
We apply a new parameterized model through linking metabolic scaling and the maximum entropy theory of ecology to quantify the intraspecific metabolic scaling exponent of brown trout populations and assess the main drivers shaping the exponent. Abstract Metabolic scaling fundamentally sets the pace of life in almost all organisms.

Performance Evaluation of Java Based Object Relational Mapping Tools [PDF]

open access: yesMehran University Research Journal of Engineering and Technology, 2013
Object persistency is the hot issue in the form of ORM (Object Relational Mapping) tools in industry as developers use these tools during software development. This paper presents the performance evaluation of Java based ORM tools.

Latitudinal Variation in Seasonal Activity and Mortality in Ratsnakes (Elaphe obsoleta)

open access: yes, 2010
The ecology of ectotherms should be particularly affected by latitude because so much of their biology is temperature dependent. Current latitudinal patterns should also be informative about how ectotherms will have to modify their behavior in response ...
