Within-species and among-species differences in growth responses to a changing climate have been well documented, yet the relative magnitude of within-species vs. among-species variation has remained largely unexplored. This missing comparison impedes our ability to make general predictions of biodi...

Abstract A dramatic insect decline has been documented on the grasslands and forests of European or North American mainland. Yet, other parts of the world and other ecosystems remain much less studied with unknown patterns. Using a unique time‐series dataset, we investigate recent trends on abundanc...

There is growing evidence that global climate change is significantly altering forest ecosystems, and will continue to do so in the future. Changes in mean climate and climate extremes such as drought, storms, cyclones and wildfires can fundamentally alter species distribution, composition, phenolog...

In oviparous species a female's choice of oviposition site can have a significant impact on off-spring survival and thereby on reproductive fitness. Here we compare the spawning behaviour of domesticated zebrafish, Danio rerio, in the laboratory with wild fish in a field-based mesocosm study in Bang...

We used long‐term (20+ yr) datasets to determine how the sum of 209 polychlorinated biphenyl congeners ([ΣPCB]), dodecachloropentacyclodecane ([mirex]), para‐para dichlorodiphenyltrichloroethane ([ p,p '‐DDT]), and total mercury ([Tot‐Hg]) concentrations have changed in Lake Ontario chinook salmon (...

The effects of introducing common carp (CC) and of adding artificial feed to fertilized rohu ponds on water quality and nutrient accumulation efficiency were studied. All ponds were stocked with 15 000 rohu ha−1. Treatments included ponds with rohu alone, rohu plus 5000 common carp ha−1 and rohu plu...

Plantations are important REDD+strategies for increasing carbon sequestration while enhancing local livelihoods. Reforestation along roads and highways under participatory forest management in southwestern Bangladesh could contribute to REDD+. This study assessed the diversity and structure of roads...

Abstract Studying postrelease effects of fisheries capture on chondrichthyans in the wild poses considerable logistical challenges. We report a laboratory-based technique to (1) simulate gill-net capture of sharks, which allows monitoring the condition of animals during recovery from a controlled ca...

We examine 87 Sr/ 86 Sr isotope ratios in transects across the otoliths of the diadromous tropical shad hilsa, Tenualosa toli, to assess the extent of movement of fish within the large Meghna (Ganges) River system and adjacent coastal waters. Hilsa collected from marine, estuarine, and freshwater ha...

Hybridization between silver carp (Hypophthalmichthys molitrix) and bighead carp (Aristichthys nobilis) has been reported to occur fairly frequently in commercial aquaculture hatcheries in Bangladesh. The consequences of hybridization for broodstock purity had not previously been investigated. Allel...

Forest carbon stocks can be estimated using some easily measureable stand variables, such as basal area, mean or maximum tree height and wood density. Estimation of stand level carbon stocks per unit area of forests or woodlands is of great importance for forestry related mitigation options of futur...

Abstract We used customized fish tanks as model fish ponds to observe grazing, swimming, and conspecific social behavior of common carp ( Cyprinus carpio ) under variable food‐resource conditions to assess alterations in feeding niche. Different food and feeding situations were created by using only...

The present research investigated the optimum surface area of periphyton substrate in earthen ponds stocked with a pre-optimized density and ratio of the Indian major carps, catla (Catla catla), rohu (Labeo rohita) and kalbaush (Labeo calbasu) to support enhanced fish production. Four treatments in ...

A mark‐recapture programme at the Pabna Irrigation and Rural Development Project (PIRDP) site in NW Bangladesh showed that Catla catla, Channa striata and Wallago attu migrated through the sluice gates, both with and against prevailing currents in different season, while the smaller Anabas testudine...

Genetic structure and natal origins of green turtle mixed stocks in southern Brazil were assessed based on analyses of mtDNA control region sequences from the Arvoredo Island (n = 115) and Cassino Beach (n = 101) feeding areas. These were compared to other mixed aggregations to examine structuring, ...
